Description of Business and Summary of Significant Accounting Policies | Description of Business and Summary of Significant Accounting Policies Description of Business FireEye, Inc., with principal executive offices located in Milpitas, California, was incorporated as NetForts, Inc. on February 18, 2004, under the laws of the State of Delaware, and changed its name to FireEye, Inc. on September 7, 2005. FireEye, Inc. and its wholly owned subsidiaries (collectively, the “Company”, “we”, “us” or “our”) provide comprehensive intelligence-based cybersecurity solutions that allow organizations to prepare for, prevent, respond to and remediate cyber attacks. Our portfolio of cyber security products and services is designed to detect and prevent attacks, as well as enable rapid discovery and response when a breach occurs. We accomplish this with products and services that adapt to changes in the threat environment in a cycle of innovation that incorporates our threat intelligence, machine-based technologies and cyber security expertise. Our core competitive advantages include: • Our high efficacy detection and prevention of known and unknown threats using machine-learning, behavioral analytics, and other intelligence-driven analysis (IDA) technologies, combined with our proprietary Multi-vector Virtual Execution (MVX) engine; • Our intelligence on threats and threat actors, based on the continuous flow of new attack data from our global network of sensors and virtual machines, as well as intelligence gathered by our security researchers, security operations analysts and incident responders; and • Our accumulated security expertise derived from responding to thousands of significant breaches over the past decade. Our threat detection and prevention products encompass appliance-based, virtual and cloud solutions for network, email, and endpoint attack vectors, and provide the first line of defense against known and unknown attacks. These products are complemented by our network forensics, cloud-based threat intelligence and analytics, managed security services, cyber security consulting and incident response offerings. In combination, our products and services enable a proactive approach to cybersecurity that extends across the security operations cycle to reduce organizations’ overall cyber-risk at a lower total cost of ownership. In January 2018, we completed the acquisition of privately held X15 Software, Inc. ("X15"), a data management company. As consideration for the acquisition, we paid approximately $20.0 million in cash and equity, subject to adjustment per the terms of the agreement. In October 2017, we acquired Clean Communications Limited (d/b/a The Email Laundry) ("The Email Laundry"), a privately-held email security company. We paid cash consideration of $4.3 million and issued 259,425 shares of our common stock with an estimated fair value of $4.4 million . In February 2016, we acquired Invotas International Corporation (“Invotas”), a provider of security automation and orchestration technology. We paid upfront cash consideration of $17.7 million and issued 742,026 shares of our common stock with an estimated fair value of $11.1 million . In January 2016, we acquired iSIGHT Security, Inc. (d/b/a iSIGHT Partners, Inc.) (“iSIGHT”), one of the world’s leading providers of cyber threat intelligence for global enterprises. We paid upfront cash consideration of $192.8 million , incurred liabilities of $39.1 million contingent upon the achievement of a threat intelligence bookings target on or before the end of the second quarter of 2018, and issued 1,793,305 shares of our common stock with an estimated fair value of $29.9 million . In June 2015, we issued $460.0 million principal amount of 1.000% Convertible Senior Notes due 2035 (the “Series A Notes”) and $460.0 million principal amount of 1.625% Convertible Senior Notes due 2035 (the “Series B Notes” and together with the Series A Notes, the “Convertible Senior Notes”), in a private placement to qualified institutional purchasers pursuant to an exemption from registration provided by Section 4(a)(2) and Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). We recognized total net proceeds after the initial purchasers' discount and issuance costs of $896.5 million . In connection with the issuance of the Convertible Senior Notes, we also entered into privately negotiated prepaid forward stock purchase transactions (each a “Prepaid Forward”) with one of the initial purchasers of the Convertible Senior Notes, pursuant to which we paid approximately $150.0 million . The amount of the prepaid is equivalent to approximately 3.3 million shares which are to be settled on or around June 1, 2020 and June 1, 2022, respectively, subject to any early settlement in whole or part of each Prepaid Forward. We sell the majority of our products, subscriptions and services to end-customers through distributors, resellers, and strategic partners, with a lesser percentage of sales directly to end-customers. Basis of Presentation and Consolidation The consolidated financial statements include the accounts of FireEye, Inc. and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such management estimates include, but are not limited to, the best estimate of selling price for our products, subscriptions and services, commissions expense, bonus expense, future taxable income, contract manufacturer liabilities, litigation and settlement costs and other loss contingencies, fair value of our equity awards, achievement of targets for performance stock units, fair value of the liability and equity components of Convertible Senior Notes and the purchase price allocation of acquired businesses. We base our estimates on historical experience and also on assumptions that we believe are reasonable. Changes in facts or circumstances may cause us to change our assumptions and estimates in future periods, and it is possible that actual results could differ from current or revised future estimates. Concentrations Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. We maintain a substantial portion of our cash and cash equivalents in money market funds invested in U.S. Treasury related obligations. Management believes that these financial institutions are financially sound and, accordingly, are subject to minimal credit risk. Deposits held with banks may exceed the amount of insurance provided on such deposits. Our short-term investments primarily consist of notes and bonds issued by corporate institutions and U.S. Government agencies. All of our investments are highly-rated by credit rating agencies and are issued by organizations with reputable credit, and therefore bear minimal credit risk. Our accounts receivables are primarily derived from a diverse set of customers across various geographical locations. We perform ongoing credit evaluations of our customers and generally do not require collateral on accounts receivable. We maintain an allowance for doubtful accounts for estimated potential credit losses. See Note 15 for information on major customers. We rely primarily on a single contract manufacturer to assemble our products. In some cases we rely on sole suppliers for a certain number of our components. Foreign Currency Translation and Transactions The functional currency of our foreign subsidiaries is the U.S. dollar. We translate all monetary assets and liabilities denominated in foreign currencies into U.S. dollars using the exchange rates in effect at the balance sheet dates and other assets and liabilities using historical exchange rates. Foreign currency denominated revenue and expenses have been re-measured using the average exchange rates in effect during each period. Foreign currency re-measurement gains and losses have been included in other income (expense) and have not been significant for the years ended December 31, 2017 , 2016 and 2015 . Cash and Cash Equivalents We consider all highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. We determine the appropriate classification of our investments at the time of purchase, and evaluate such designation at each balance sheet date. Short-term Investments We classify our investments in debt and equity securities as available-for-sale and record these investments at fair value. Investments with an original maturity of three months or less at the date of purchase are considered cash equivalents, while all other investments are classified as short-term or long-term based on the nature of the investments, their maturities, and their availability for use in current operations. Unrealized gains and losses are reported as a component of other comprehensive loss. Realized gains and losses are determined based on the specific identification method, and are reflected in our Consolidated Statements of Operations. We regularly review our investment portfolio to identify and evaluate investments that have indicators of possible impairment. Factors considered in determining whether a loss is other-than-temporary include, but are not limited to: the length of time and extent a security’s fair value has been below its cost, the financial condition and near-term prospects of the investee, the credit quality of the security’s issuer, likelihood of recovery and our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in value. For our debt instruments, we also evaluate whether we have the intent to sell the security or it is more likely than not that we will be required to sell the security before recovery of its cost basis. Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by management. If the cost of an investment exceeds its fair value, we evaluate, among other factors, general market conditions, credit quality of debt instrument issuers, the duration and extent to which the fair value is less than cost and whether we have plans to sell the security, or it is more likely than not that we will be required to sell the security, before recovery. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense) and a new cost basis in the investment is established. Fair Value of Financial Instruments We define fair value as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, we consider the principal or most advantageous market in which to transact and the market-based risk. We apply fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities due to their short-term nature. Accounts Receivable Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on our assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice, each partner’s expected ability to pay and the collection history with each partner, when applicable, to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. Inventories Inventories are stated at the lower of cost or net realizable value. Provisions have been made to reduce all slow-moving, obsolete or unusable inventories to their net realizable values. We purchase completed units from contract manufacturers and substantially all of our inventories are finished goods held for use as service replacements. As of December 31, 2017 and 2016 , the reserves for excess and obsolete inventories were $4.7 million and $3.8 million , respectively. Deferred Costs of Revenue Deferred cost of revenue consists of direct and incremental costs related to product revenue deferred in accordance with the Company’s revenue recognition policy. Deferred cost of revenue that will be realized within the succeeding 12 month period is classified as current, and included in prepaid expenses and other current assets on the consolidated balance sheets. The remaining balance is classified as non-current, and included in deposits and other long-term assets. Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally two to five years. The estimated useful lives of property and equipment are described below: Property and Equipment Useful Life Computer equipment and software 2 to 5 years Leasehold improvements Shorter of estimated useful life or remaining lease term Furniture and fixtures 5 years Machinery and equipment 2 to 5 years Demonstration Units Product demonstration units are included in prepaid expenses and other current assets on the consolidated balance sheets. Demonstration units are recorded at cost and are amortized over the estimated useful life from the date of transfer from inventory, generally 12 months. We generally do not resell units that have been used for demonstration purposes. Impairment of Long-Lived Assets We evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether or not the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the assets exceeds the fair value of the asset. Through December 31, 2017 we have not written down any of our long-lived assets as a result of impairment. Business Combinations We have accounted for all of our acquisitions using the acquisition method. The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired, based on their estimated fair values. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. Critical estimates in valuing certain identifiable assets include, but are not limited to, expected long-term market growth, future expected operating expenses, costs of capital, and appropriate discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and, as a result, actual results may differ from estimates. Goodwill and Purchased Intangibles Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible assets acquired. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has determined that it operates as one reporting unit and has selected December 1 as the date to perform its annual impairment test. In the valuation of its goodwill, the Company must make assumptions regarding estimated future cash flows to be derived from the Company. If these estimates or their related assumptions change in the future, the Company may be required to record impairment for these assets. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. If the net book value exceeds its fair value, then the Company would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. The impairment loss would be calculated by comparing the implied fair value of the Company to its net book value. In calculating the implied fair value of the Company’s goodwill, the fair value of the Company would be allocated to all of the other assets and liabilities based on their fair values. The excess of the fair value of the Company over the amount assigned to its other assets and liabilities is the implied fair value of goodwill. An impairment loss would be recognized when the carrying amount of goodwill exceeds its implied fair value. There was no impairment of goodwill recorded for the years ended December 31, 2017 , 2016 or 2015 . Purchased intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. Purchased intangible assets with indefinite lives are assessed for potential impairment annually, or when events or circumstances indicate that their carrying amounts might be impaired. Warranties We generally provide a one -year warranty on hardware. We do not accrue for potential warranty claims as a component of cost of product revenue as all product warranty claims are satisfied under our support and maintenance contracts. Deferred Revenue Deferred revenue consists of amounts that have been invoiced and for which the Company has the right to bill, but that have not been recognized as revenue. Deferred revenue that will be realized during the succeeding 12 month period is recorded as current, and the remaining deferred revenue is recorded as non-current. Contract Manufacturer Liabilities We outsource most of our manufacturing, repair, and supply chain management operations to our independent contract manufacturers and payments to such manufacturers are a significant portion of our product cost of revenue. Although we could be contractually obligated to purchase manufactured products, we generally do not own the manufactured products. Product title transfers from our independent contract manufacturers to us and to our partners upon shipment. Our independent contract manufacturers assemble our products using design specifications, quality assurance programs, and standards that we establish, and they procure components and assemble our products based on our demand forecasts. These forecasts represent our estimates of future demand for our products based upon historical trends and analysis from our sales and product management functions as adjusted for overall market conditions. If the actual component usage and product demand are significantly lower than forecast, we may accrue for costs for contractual manufacturing commitments in excess of our forecasted demand, including costs for excess components or for carrying costs incurred by our contract manufacturers. To date, we have not accrued any significant costs associated with this exposure. Revenue Recognition We generate revenue from the sales of products, subscriptions, support and maintenance and professional services, primarily through our indirect relationships with our partners as well as end customers through our direct sales force. Our products include operating system software that is integrated into the appliance hardware and is deemed essential to its functionality. As a result, we account for product revenue in accordance with Accounting Standards Codification 605, Revenue Recognition, and all related interpretations, as all of our security appliance deliverables include proprietary operating system software, which together delivers the essential functionality of our products. Our professional services consist primarily of time and materials based contracts, and the revenue is recognized as costs are incurred at amounts represented by the agreed-upon billing amounts. Revenue from fixed-price professional services engagements are recognized under the proportional performance method of accounting. Revenue is recognized when all of the following criteria are met: • Persuasive Evidence of an Arrangement Exists . We rely upon non-cancelable sales agreements and purchase orders to determine the existence of an arrangement. • Delivery has Occurred . We use shipping documents or transmissions of service contract registration codes to verify delivery. • The Fee is Fixed or Determinable . We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction. • Collectability is Reasonably Assured . We assess collectability based on credit analysis and payment history. Our products include security product families that address critical attack vectors, including solutions to detect and prevent attacks targeting networks, email, and endpoint devices. When our solutions are deployed on an appliance, the appliance and the related subscription and support services qualify as separate units of accounting. Therefore, product revenue from these appliances is recognized at the time of shipment. At the time of shipment, product revenue meets the criteria for fixed or determinable fees. In addition, payment from our partners is not contingent on the partners' collection from their end-customers. Our partners do not stock products and do not have any stock rotation rights. We recognize subscription and support and maintenance service revenue ratably over the contractual service period, which is typically one or three years. Professional services revenue, including incident response and related consulting services for our customers who have experienced a cybersecurity breach or who require assistance assessing the vulnerability of their networks, and training services revenue is recognized as the services are rendered. Revenue from the sale of stand-alone software bundled with services is recognized ratably over contract term as we do not have Vendor Specific Objective Evidence, or VSOE, for the undelivered elements. Most of our arrangements, other than renewals of subscriptions and support and maintenance services, are multiple-element arrangements with a combination of product, subscriptions, support and maintenance, and other services. For multiple-element arrangements, we allocate revenue to each unit of accounting based on an estimated selling price at the arrangement inception. The estimated selling price for each element is based upon the following hierarchy: VSOE of selling price, if available, third-party evidence (“TPE”) of selling price, if VSOE of selling price is not available, or best estimate of selling price (“BESP”), if neither VSOE of selling price nor TPE of selling price are available. The total arrangement consideration is allocated to each separate unit of accounting using the relative estimated selling prices of each unit based on the aforementioned selling price hierarchy. We limit the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting of any specified performance conditions. To determine the estimated selling price in multiple-element arrangements, we seek to establish VSOE of selling price using the prices charged for a deliverable when sold separately and, for subscriptions and support and maintenance, based on the renewal rates and discounts offered to partners. If VSOE of selling price cannot be established for a deliverable, we seek to establish TPE of selling price by evaluating similar and interchangeable competitor products or services in standalone arrangements with similarly situated partners. However, as our products contain a significant element of proprietary technology and offer substantially different features and functionality from our competitors, we are unable to obtain comparable pricing of our competitors’ products with similar functionality on a standalone basis. Therefore, we have not been able to obtain reliable evidence of TPE of selling price. If neither VSOE nor TPE of selling price can be established for a deliverable, we establish BESP primarily based on historical transaction pricing. Historical transactions are segregated based on our pricing model and our go-to-market strategy, which include factors such as type of sales channel (reseller, distributor, or end-customer), the geographies in which our products and services were sold (domestic or international), offering type (products, subscriptions or services), and whether or not the opportunity was identified by our sales force or by our partners. In analyzing historical transaction pricing, we evaluate whether a majority of the prices charged for a product, as represented by a percentage of list price, fall within a reasonable range. To further support the best estimate of selling price as determined by the historical transaction pricing or when such information is unavailable, such as when there are limited sales of a new product, we consider the same factors we have established through our pricing model and go-to-market strategy. The determination of BESP is made through consultation with and approval by our management. We have established the estimated selling price of all of our deliverables using BESP. Shipping charges billed to partners are included in revenue and related costs are included in cost of revenue. Sales commissions and other incremental costs to acquire contracts are also expensed as incurred and are recorded in sales and marketing expense. After receipt of a partner order, any amounts billed in excess of revenue recognized are recorded as deferred revenue. Advertising Costs Advertising costs, which are expensed and included in sales and marketing expense when incurred, were $2.6 million , $3.6 million and $5.1 million during the years ended December 31, 2017 , 2016 and 2015 , respectively. Software Development Costs The costs to develop internal-use software are subject to capitalization and begin amortizing once the software is substantially ready for use. These costs are included in property and equipment and are generally amortized over 3 years. All other software development costs are expensed as incurred and included in research and development expense on the consolidated statements of operations. Stock-Based Compensation Compensation expense related to stock-based transactions, including employee and non-employee director awards and our 2013 Employee Stock Purchase Plan (the "ESPP"), is measured and recognized in the financial statements based on fair value. The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model and a single option award approach. This model requires that at the date of grant we determine the fair value of the underlying common stock, the expected term of the award, the expected volatility of the price of our common stock, risk-free interest rates, and expected dividend yield of our common stock. The fair value of restricted stock awards and restricted stock units is based on the closing market price of our common stock on the date of grant. The stock-based compensation expense is recognized using a straight-line basis over the requisite service period of the entire awards, which is generally four years , unless the awards are subject to performance conditions, in which case the Company recognizes compensation expense over the requisite service period of each vesting tranche. For performance-based awards, the Company recognizes compensation expense when it becomes probable that the performance criteria set by the Board of Directors will be achieved. Beginning January 1, 2016 with the adoption of ASU 2016-09, we elected to recognize forfeitures as they occur, and no longer estimate a forfeiture rate when calculating the stock-based compensation for our equity awards. Stock-based compensation for the year ended December 31, 2015 was calculated using an estimated forfeiture rate based on an analysis of our actual historical forfeitures. We account for stock options issued to non-employees based on the fair value of the awards determined using the Black-Scholes option-pricing model. The fair value of stock options granted to non-employees is remeasured as the stock options vest, and the resulting change in value, if any, is recognized in the statement of operations during the period the related services are rendered. Income Taxes We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carry forwards. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. We apply the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation settlement. The second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. We recognize interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statements of operations. Accrued interest and penalties are included within other long-term liabilities in the consolidated balance sheets. Net Loss Per Share Attributable to Common Stockholders We calculate our basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for companies with participating securities. Under the two-class method, in periods when the Company has net income, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period convertible preferred stock non-cumulative dividends, between common stock and the convertible preferred stock. In computing diluted net income attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. The Company’s basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock are considered common stock equivalents, but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive. Convertible Senior Notes We allocated the principal amount of the Convertible Senior Notes between its liability and equity components. The carrying amount of the liability component was determined by measuring the fair value of a similar debt instrumen |

Fair Value Measurements | Fair Value Measurements The accounting guidance for fair value measurements provides a framework for measuring fair value on either a recurring or nonrecurring basis, whereby the inputs used in our valuation techniques are assigned a hierarchical level. The following are the three levels of inputs to measure fair value: • Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2: Inputs that reflect quoted prices for identical assets or liabilities in less active markets; quoted prices for similar assets or liabilities in active markets; benchmark yields, reported trades, broker/dealer quotes, inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3: Unobservable inputs that reflect our own assumptions incorporated in valuation techniques used to measure fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. We consider an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and consider an inactive market to be one in which there are infrequent or few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, our own or the counterparty’s non-performance risk is considered in measuring the fair values of assets. The following table presents our assets and liabilities measured at fair value on a recurring basis using the above input categories (in thousands): As of December 31, 2017 As of December 31, 2016 Description Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Cash equivalents: Money market funds $ 208 $ — $ — $ 208 $ 449 $ — $ — $ 449 Treasury bills $ 3,098 $ — $ — $ 3,098 $ — $ — $ — $ — Total cash equivalents 3,306 — — 3,306 449 — — 449 Short-term investments: Certificates of deposit — — — — — 9,569 — 9,569 Commercial paper — 4,987 — 4,987 — 29,920 — 29,920 Corporate notes and bonds — 438,024 — 438,024 — 420,684 — 420,684 U.S. Government agencies — 272,900 — 272,900 — 251,885 — 251,885 Total short-term investments — 715,911 — 715,911 — 712,058 — 712,058 Total assets measured at fair value $ 3,306 $ 715,911 $ — $ 719,217 $ 449 $ 712,058 $ — $ 712,507 Liabilities Contingent earn-out $ — $ — $ — $ — $ — $ — $ 41,332 $ 41,332 Total liabilities measured at fair value $ — $ — $ — $ — $ — $ — $ 41,332 $ 41,332 The estimated fair value of the contingent earn-out incurred in connection with our acquisition of iSIGHT is considered to be a Level 3 measurement due to the use of significant unobservable inputs. The value was determined using a discounted risk-adjusted expected (probability-weighted) cash flow methodology, by applying a real options approach model. The real options approach incorporated management's estimates of expected quarterly growth rates in bookings ( 63% on average), which could not be corroborated by observable market data, with the volatility of revenue for comparable companies ( 16.5% on average) and the correlation between comparable companies' quarterly revenue growth and that of the S&P 500 Index ( 44.7% on average), which are observable in the market, to determine the probability of achieving estimated bookings within the earn-out period of performance ( 2.5 years ). The resulting expected earn-out payment was discounted back to present value using our cost of debt (ranging from 6.3% to 7.1% ). The following is a reconciliation of the Level 3 contingent earn-out liability for the years ended December 31, 2017 and 2016 (in thousands): Amount Balance at acquisition (January 14, 2016) $ 35,588 Measurement period adjustments (1) 3,500 Changes in fair value (2) 2,356 Cash payments (112 ) Balance as of December 31, 2016 41,332 Changes in fair value (2) (54 ) Cash payments (41,278 ) Balance as of December 31, 2017 $ — (1) See Note 5 Business Combinations for adjustments made to initial amounts recorded in our acquisition of iSIGHT. (2) Changes in fair value are recorded in general and administrative expenses in our consolidated statements of operations. Additionally, we have a restructuring liability related to certain real estate facilities which was calculated based on the present value of future lease payments, less estimated sublease income, discounted at a rate commensurate with our current cost of financing. This non-recurring fair value measurement is considered to be a Level 3 measurement due to the use of significant unobservable inputs. To the extent that actual sublease income or the timing of subleasing these facilities is different than initial estimates, we will adjust the restructuring liability in the period during which such information becomes known. See Note 6 Restructuring Charges for a reconciliation of this liability. We measure certain assets, including goodwill, intangible assets and our equity-method investment in a private company at fair value on a nonrecurring basis when there are identifiable events or changes in circumstances that may have a significant adverse impact on the fair value of these assets. No such events or changes occurred during the year ended December 31, 2017 . The estimated fair value of the Convertible Senior Notes as of December 31, 2017 was determined to be $851.3 million , based on quoted market prices. We consider the fair value of the Convertible Senior Notes to be a Level 2 measurement as they are not actively traded. |

Business Combinations [Abstract] | |
Business Combinations | Business Combinations On October 20, 2017, we acquired all of the outstanding shares of The Email Laundry, a privately held email security company, which is expected to enhance our current email offerings. In connection with this acquisition, we paid cash consideration of $4.3 million and issued 259,425 shares of our common stock with an estimated fair value of $4.4 million , resulting in total purchase consideration of $8.7 million . The purchase price is subject to customary working capital and related adjustments. The purchase price was allocated to intangible assets of $2.7 million , goodwill of $6.4 million and tangible net liabilities of $0.3 million . The intangible assets are composed of technology and customer relationships, each with an estimated weighted average useful life of 3 years. The goodwill is primarily attributable to the know-how of the workforce and is not expected to be deductible for U.S. federal income tax purposes. The results of operations of The Email Laundry have been included in our consolidated statements of operations from the acquisition date. Pro forma financial information has not been presented for this acquisition as the impact to our consolidated financial statements was not material. On January 11, 2018, we completed the acquisition of privately held X15, a data management company. We expect that the X15 technology will be incorporated into the foundation for our platform and analytics capabilities going forward. As consideration for the acquisition, we paid approximately $20.0 million in cash and equity, subject to adjustment per the terms of the agreement. We are currently in the process of completing the preliminary purchase price allocation, which will be included in our Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. Acquisitions in 2016 Acquisition of iSIGHT On January 14, 2016, we acquired all of the outstanding shares of privately held iSIGHT, one of the world’s leading providers of cyber threat intelligence for global enterprises. The acquisition extends our intelligence network to create an advanced and comprehensive private cyber threat intelligence operation, providing customers with higher fidelity alerts, context to prioritize threats and the strategic insights to proactively prepare for threats that might target their industry or region. In connection with this acquisition, we paid upfront cash consideration of $192.8 million , incurred liabilities of $39.1 million contingent upon the achievement of a threat intelligence bookings target on or before the end of the second quarter of 2018, and issued 1,793,305 shares of our common stock with an estimated fair value of $29.9 million ; 1,793,297 of which were released in February 2017 to former stockholders of iSIGHT once the threat intelligence bookings target was determined to have been achieved. This resulted in total purchase consideration of $261.8 million . The number of shares was fixed at the completion of the acquisition and is the maximum number of shares that can be released. The contingent earn-out liability is included in accrued compensation on the consolidated balance sheet as of December 31, 2017 , and subsequently resulted in a cash payment of $41.3 million during February 2017, once the threat intelligence bookings target was determined to have been achieved. The acquisition of iSIGHT was accounted for in accordance with the acquisition method of accounting for business combinations with FireEye as the accounting acquirer. During the three months ended June 30, 2016, we finalized our valuation analysis and revised our preliminary estimates of the earn-out liability and related fair value of common stock contingent upon the achievement of a threat intelligence bookings target by $3.5 million and $1.7 million , respectively, resulting in a higher purchase price of $5.2 million . As a result, we also revised our preliminary estimate of customer relationship and content intangible assets by $1.1 million and $1.2 million , respectively, resulting in an additional $0.2 million of intangible amortization. We expensed the related acquisition costs of $1.9 million in general and administrative expenses. We also assumed and paid liabilities of $7.0 million for transaction costs incurred by iSIGHT prior to acquisition, which were accounted for separate from consideration transferred. Allocation of the purchase price of $261.8 million was as follows (in thousands): Amount Net tangible liabilities assumed $ (18,248 ) Intangible assets 85,100 Deferred tax liability (11,637 ) Goodwill 206,623 Total purchase price allocation $ 261,838 The purchase price exceeded the fair value of the net tangible and identifiable intangible assets acquired, resulting in the recognition of goodwill. Goodwill is primarily attributable to expected synergies in our subscription offerings and cross-selling opportunities. None of the goodwill is expected to be deductible for U.S. federal income tax purposes. Intangible assets consist primarily of customer relationships, content, developed technology and other intangible assets. Customer relationship intangibles relate to iSIGHT's ability to sell current and future content, as well as products built around this content, to its existing customers. Content intangibles represent threat intelligence data gathered through the analysis of cyber-crimes, cyber attacks, hacking, and cyber criminals. Intangible assets attributable to developed technology include a combination of patented and unpatented technology, trade secrets, computer software and research processes that represent the foundation for the existing and planned new products to facilitate the generation of new content. The estimated useful life and fair values of the identifiable intangible assets are as follows (in thousands): Estimated Useful Life (in years) Amount Customer relationships 7 $ 33,700 Content 4 30,100 Developed technology 4-6 17,100 Trade name 5 3,100 Non-competition agreements 2 1,100 Total identifiable intangible assets $ 85,100 The value of customer relationships and content was estimated using the excess earnings method, an income approach (Level 3), which converts projected revenues and costs into cash flows. To reflect the fact that certain other assets contribute to the cash flows generated, the returns for these contributory assets were removed to arrive at estimated cash flows solely attributable to the customer relationships and content, which were discounted at rates of 15% and 14% , respectively. The value of developed technology and the trade name was estimated using the relief-from-royalty method, an income approach (Level 3), which estimates the cost savings that accrue to the owner of the intangible asset that would otherwise be payable as royalties or license fees on revenues earned through the use of the asset. A royalty rate is applied to the projected revenues associated with the intangible asset to determine the amount of savings, which is then discounted to determine the fair value. The developed technology and trade name were valued using royalty rates of 10% and 1% , respectively, and discounted at rates of 14% and 15% , respectively. The results of operations of iSIGHT have been included in our consolidated statements of operations from the acquisition date, and contributed $9.4 million to our consolidated revenues and $2.3 million to our consolidated net loss during the three months ended March 31, 2016. Subsequent to March 31, 2016, the operations of iSIGHT were integrated with the Company's operations. Pro forma results of operations have not been presented because the acquisition was not material to our results of operations. Acquisition of Invotas On February 1, 2016, we acquired all of the outstanding shares of privately held Invotas, a provider of security automation and orchestration technology. This acquisition enables us to deliver a premier security orchestration capability as part of our global threat management platform to unify cyber attack detection results, threat intelligence and incident response elements of an organization’s security program into a single console, giving enterprises the ability to respond more quickly to attacks through automation. In connection with this acquisition, we paid upfront cash consideration of $17.7 million and issued 742,026 shares of our common stock with an estimated fair value of $11.1 million . This resulted in total purchase consideration of $28.8 million . Additionally, we replaced unvested option awards with grants of 95,614 restricted stock units which will vest over the requisite service period of four years, and granted an additional 1,002,748 restricted stock units which were scheduled to vest upon the achievement of stated performance milestones over a period of approximately three years, subject to continuing service during that time. A portion of these awards have since been released following the achievement of the first milestone, while another portion of these awards were modified to vest subject only to continuing service. These awards are being recognized as operating expense over the requisite service periods as they relate to post-combination services. The acquisition of Invotas was accounted for in accordance with the acquisition method of accounting for business combinations with FireEye as the accounting acquirer. We expensed the related acquisition costs of $0.5 million in general and administrative expenses. We also assumed and paid liabilities of $0.7 million for transaction costs incurred by Invotas prior to acquisition, which were accounted for separate from consideration transferred. Under the acquisition method of accounting, the total purchase consideration is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values. The total purchase price of $28.8 million was allocated using information currently available to us. Allocation of the purchase price was as follows (in thousands): Amount Net tangible liabilities assumed $ (306 ) Intangible assets 8,400 Deferred tax liability (688 ) Goodwill 21,349 Total purchase price allocation $ 28,755 The purchase price exceeded the fair value of the net tangible and identifiable intangible assets acquired, resulting in the recognition of goodwill. Goodwill is primarily attributable to increased selling opportunities. None of the goodwill is expected to be deductible for U.S. federal income tax purposes. Intangible assets consist primarily of developed technology, in-process research and development and other intangible assets. Developed technology intangibles include a combination of patented and unpatented technology, trade secrets, computer software and research processes that represent the foundation for the existing and planned new product offerings. The in-process research and development intangible represents the estimated fair value of acquired research projects which had not reached technological feasibility at acquisition date, but have since been developed into products. The estimated useful life and fair values of the identifiable intangible assets are as follows (in thousands): Estimated Useful Life (in years) Amount Developed technology 4 $ 4,500 In-process research and development N/A 2,800 Customer relationships 10 800 Non-competition agreements 3 300 Total identifiable intangible assets $ 8,400 The value of developed technology and in-process research and development (IPR&D) was estimated using the excess earnings method, an income approach (Level 3), which converts projected revenues and costs into cash flows. To reflect the fact that certain other assets contribute to the cash flows generated, the returns for these contributory assets were removed to arrive at estimated cash flows solely attributable to the developed technology and IPR&D, which were discounted at rates of 16% and 17% , respectively. In-process research and development of $2.8 million obtained in our acquisition of Invotas reached technological feasibility during the year ended December 31, 2016, resulting in its reclassification to developed technology. The results of operations of Invotas have been included in our consolidated statements of operations from the acquisition date, although such results did not have a material impact on our consolidated revenues or net loss during the year ended December 31, 2017 . Pro forma results of operations have not been presented because the acquisition was not material to our results of operations.

Restructuring and Related Activities [Abstract] | |
Restructuring Charges | Restructuring Charges In addition to our previous restructuring activities which took place in 2014, our Board of Directors approved a restructuring plan and reduction in workforce in August 2016 designed to reduce operating expenses and align our expense structure with current growth expectations. This resulted in a 10% reduction in our workforce, the consolidation of certain real estate facilities and impairment of certain assets. The following table sets forth a summary of restructuring activities during the years ended December 31, 2017 and 2016 (in thousands): Severance and related costs Facilities costs Total costs Balance, December 31, 2015 $ — $ 217 $ 217 Provision for restructuring charges 21,529 1,492 23,021 Cash payments (20,308 ) (1,201 ) (21,509 ) Other adjustments — 1,738 1,738 Balance, December 31, 2016 1,221 2,246 3,467 Provision for restructuring charges — — — Cash payments (752 ) (1,046 ) (1,798 ) Other adjustments (469 ) (265 ) (734 ) Balance, December 31, 2017 $ — $ 935 $ 935 The total provision for restructuring charges during the year ended December 31, 2016 of $27.6 million includes $23.0 million of cash charges shown above, as well as non-cash charges of $3.5 million related to fixed asset write-offs and $1.1 million related to stock-based compensation. Other adjustments of $1.7 million during the year ended December 31, 2016 primarily represented a reclassification of deferred rent liabilities related to closed facilities. Other adjustments of negative $0.7 million during the year ended December 31, 2017 primarily represented relief of unused benefits, changes in fair value and foreign currency fluctuations. The remaining restructuring balance of $0.9 million at December 31, 2017 is composed of non-cancelable lease costs which we expect to pay over the terms of the related obligations through the third quarter of 2024, net of sublease income. |

Debt Disclosure [Abstract] | |
Convertible Senior Notes | Convertible Senior Notes Convertible Senior Notes In June 2015, we issued $460.0 million principal amount of 1.000% Convertible Senior Notes due 2035 (the "Series A Notes") and $460.0 million principal amount of 1.625% Convertible Senior Notes due 2035 (the “Series B Notes” and together with the Series A Notes, the “Convertible Senior Notes”), including the full exercise of the initial purchasers' over-allotment option, in a private placement to qualified institutional purchasers pursuant to an exemption from registration provided by Section 4(a)(2) and Rule 144A under the Securities Act of 1933, as amended. The net proceeds after the initial purchasers' discount of $23.0 million and issuance costs of $0.5 million from the Convertible Senior Notes were $896.5 million . The Series A Notes and Series B Notes bear interest at 1.000% per year and 1.625% per year, respectively, payable semiannually in arrears on June 1 and December 1 of each year, beginning December 1, 2015. The Convertible Senior Notes mature on June 1, 2035, unless earlier repurchased, redeemed or converted. The Convertible Senior Notes are unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Convertible Senior Notes. They rank equally in right of payment with all of our existing and future liabilities that are not expressly subordinated to the Convertible Senior Notes and effectively rank junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness. They are structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The Convertible Senior Notes do not contain any financial covenants and do not restrict us from paying dividends or issuing or repurchasing our other securities. The initial conversion rate on each series of Convertible Senior Notes is 16.4572 shares of our common stock per $1,000 principal amount of Convertible Senior Notes, which is equivalent to an initial conversion price of approximately $60.76 per share of common stock. The conversion rate of each series of Convertible Senior Notes may be adjusted upon the occurrence of certain specified events, but not for accrued and unpaid interest. Holders may convert the Convertible Senior Notes at their option in multiples of $1,000 principal amount prior to March 1, 2035, excluding the period from March 1, 2020 to June 1, 2020 in the case of the Series A Notes and March 1, 2022 to June 1, 2022 in the case of the Series B Notes, only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ended on September 30, 2015 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price for the Convertible Senior Notes of the relevant series on each applicable trading day; • during the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of Series A Notes or Series B Notes, as applicable, for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate for the notes of the relevant series on each such trading day; • if we call any or all of the Convertible Senior Notes of a series for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the relevant redemption date; or • upon the occurrence of specified corporate events, as specified in each indenture governing the Convertible Senior Notes. Regardless of the foregoing conditions, holders may convert their Convertible Senior Notes at their option in multiples of $1,000 principal amount at any time during the period from March 1, 2020 to June 1, 2020 in the case of the Series A Notes and during the period from March 1, 2022 to June 1, 2022 in the case of the Series B Notes, or after March 1, 2035 until maturity for either series of Convertible Senior Notes. Upon conversion, the Convertible Senior Notes can be settled in cash, shares of our common stock or any combination thereof at our option. We may be required by holders of the Convertible Senior Notes to repurchase all or any portion of their Convertible Senior Notes at 100% of the principal amount plus accrued and unpaid interest, on each of June 1, 2020, June 1, 2025 and June 1, 2030, in the case of the Series A Notes, and each of June 1, 2022, June 1, 2025 and June 1, 2030 in the case of the Series B Notes. Holders may also require us to repurchase the Convertible Senior Notes if we undergo a "fundamental change," as defined in each indenture governing the Convertible Senior Notes, at a purchase price equal to 100% of the principal amount, plus accrued and unpaid interest. Additionally, we may redeem for cash all or any portion of the Series B Notes on or after June 1, 2020 until June 1, 2022 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending not more than three trading days immediately preceding the date we provide notice of redemption. We also may redeem for cash all or any portion of the Series A Notes on or after June 1, 2020 until maturity and all or any portion of the Series B Notes on or after June 1, 2022 until maturity, regardless of the foregoing sale price condition. In accordance with accounting for debt with conversions and other options, we allocated the principal amount of the Convertible Senior Notes into liability and equity components. We also allocated the total amount of initial purchasers' discount and transaction costs incurred to the liability and equity components using the same proportions as the proceeds from the Convertible Senior Notes. Transaction costs of $0.4 million and $0.1 million and initial purchasers' discount of $17.6 million and $5.4 million were attributable to the liability component and equity component of the Convertible Senior Notes, respectively. The liability and equity components of the Convertible Senior Notes consisted of the following (in thousands): As of December 31, 2017 2016 Series A Notes Series B Notes Series A Notes Series B Notes Liability component: Principal $ 460,000 $ 460,000 $ 460,000 $ 460,000 Less: Convertible senior notes discounts and issuance costs, net of amortization (53,762 ) (86,660 ) (74,126 ) (103,894 ) Net carrying amount $ 406,238 $ 373,340 $ 385,874 $ 356,106 Equity component, net of issuance costs $ 92,567 $ 117,834 $ 92,567 $ 117,834 The unamortized discounts and issuance costs as of December 31, 2017 will be amortized over a weighted-average remaining period of approximately 3.7 years . Interest expense for the years ended December 31, 2017 , 2016 and 2015 related to the Convertible Senior Notes consisted of the following (in thousands): Year Ended December 31, 2017 2016 2015 Series A Notes Series B Notes Series A Notes Series B Notes Series A Notes Series B Notes Coupon interest $ 4,600 $ 7,475 $ 4,600 $ 7,475 $ 2,683 $ 4,361 Amortization of convertible senior notes discounts and issuance costs 20,364 17,234 19,343 16,439 10,833 9,236 Total interest expense recognized $ 24,964 $ 24,709 $ 23,943 $ 23,914 $ 13,516 $ 13,597 Effective interest rate on the liability component 6.5 % 6.9 % 6.5 % 7.0 % 6.5 % 7.1 % Prepaid Forward Stock Purchase In connection with the issuance of the Convertible Senior Notes, we also entered into privately negotiated Prepaid Forwards with one of the initial purchasers of the Convertible Senior Notes (the “Forward Counterparty”), pursuant to which we paid approximately $150.0 million . The amount of the prepaid is equivalent to approximately 3.3 million shares which are to be settled on or around June 1, 2020 and June 1, 2022, respectively, subject to any early settlement, in whole or in part, of each Prepaid Forward. The Prepaid Forwards are intended to facilitate privately negotiated derivative transactions by which investors in the Convertible Senior Notes will be able to hedge their investment in the Convertible Senior Notes. In the event we pay any cash dividends on our common stock, the Forward Counterparty will pay an equivalent amount back to us. The related shares were accounted for as a repurchase of common stock, and are presented as Treasury Stock in the consolidated balance sheets. The 3.3 million shares of common stock purchased under the Prepaid Forwards are excluded from weighted-average shares outstanding for basic and diluted EPS purposes although they remain legally outstanding. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Leases We lease our facilities under various non-cancelable operating leases, which expire on various dates through the year ending December 31, 2027. Rent expense is recognized using the straight-line method over the term of the lease. Rent expense, net of sublease income, was $19.5 million , $14.9 million and $14.4 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. The aggregate future non-cancelable minimum rental payments on our operating leases, as of December 31, 2017 , are as follows (in thousands): Years Ending December 31, Amount 2018 $ 17,217 2019 13,270 2020 11,553 2021 10,532 2022 8,737 2023 and thereafter 31,576 Total $ 92,885 Total future non-cancelable minimum rental payments have not been reduced by future minimum sublease rentals totaling $6.4 million . We are party to letters of credit totaling $3.3 million and $3.1 million as of December 31, 2017 and 2016 , respectively, issued primarily in support of operating leases for several of our facilities. These letters of credit are collateralized by a line with our bank. No amounts have been drawn against these letters of credit. Contract Manufacturer Commitments Our independent contract manufacturers procure components and assemble our products based on our forecasts. These forecasts are based on estimates of future demand for our products, which are in turn based on historical trends and an analysis from our sales and product marketing organizations, adjusted for overall market conditions. In order to reduce manufacturing lead times and plan for adequate supply, we may issue forecasts and orders for components and products that are non-cancelable. As of December 31, 2017 and 2016 , we had non-cancelable open orders of $11.6 million and $10.2 million , respectively. We are required to record a liability for firm, non-cancelable and unconditional purchase commitments with contract manufacturers and suppliers for quantities in excess of our future demand forecasts. As of December 31, 2017 , we have not accrued any significant costs for such non-cancelable commitments. Purchase Obligations As of December 31, 2017 , we had approximately $12.5 million of non-cancelable firm purchase commitments primarily for purchases of software and services. In those situations in which we have received delivery of the goods or services as of December 31, 2017 under purchase orders outstanding as of the same date, such amounts are reflected in the consolidated balance sheet as accounts payable or accrued liabilities, and are excluded from the $12.5 million . Litigation From time to time, we are involved in claims and legal proceedings that arise in the ordinary course of business. Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources, or require us to enter into agreements which may not be available on terms favorable to us or at all. To the extent there is a reasonable possibility that a loss exceeding amounts already recognized may be incurred, and the amount of such additional loss would be material, we will either disclose the estimated additional loss or state that such an estimate cannot be made. We do not currently believe that it is reasonably possible that additional losses in connection with litigation arising in the ordinary course of business would be material. Indemnification Under the indemnification provisions of our standard sales related contracts, we agree to defend our customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. Our exposure under these indemnification provisions is generally limited to the total amount paid by our customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose us to losses in excess of the amount received under the agreement. In addition, we indemnify our officers, directors, and certain key employees for actions taken while they are or were serving in good faith in such capacities. Through December 31, 2017 , there have been no claims under any indemnification provisions. |

Equity Award Plans | Equity Award Plans We have operated under our 2013 Equity Incentive Plan ("2013 Plan") since our initial public offering ("IPO") in September 2013. Our 2013 Plan provides for the issuance of restricted stock and the granting of options, stock appreciation rights, performance shares, performance units and restricted stock units to our employees, officers, directors and consultants. Our 2013 Plan provides for annual increases in the number of shares available for issuance on the first day of each fiscal year. Awards granted under the 2013 Plan vest over the periods determined by our Board of Directors or compensation committee of our Board of Directors, generally four years , and stock options granted under the 2013 Plan expire no more than ten years after the date of grant. In the case of an incentive stock option granted to an employee who at the time of grant owns stock representing more than 10% of the total combined voting power of all classes of stock, the exercise price shall be no less than 110% of the fair value per share on the date of grant, and the award shall expire five years from the date of grant. For options granted to any other employee, the per share exercise price shall be no less than 100% of the fair value per share on the date of grant. In the case of non-statutory stock options and options granted to consultants, the per share exercise price shall be no less than 100% of the fair value per share on the date of grant. Stock that is purchased prior to vesting is subject to our right of repurchase at any time following termination of the participant's service for so long as such stock remains unvested. Approximately 11.7 million sh ares and 10.0 million shares of our common stock were reserved for future grants as of December 31, 2017 and 2016 , respectively, under the 2013 Plan . As of January 1, 2018, an additional 9,355,227 shares of common stock became available for future grants under our 2013 Plan pursuant to provisions thereof that automatically increase the share reserve under such plan each year. Our ESPP allows eligible employees to acquire shares of our common stock at 85% of the lower of the fair market value of our common stock on the first trading day of each offering period or on the exercise date. Our ESPP provides for annual increases in the number of shares available for issuance on the first day of each fiscal year. An aggregate of 2,985,358 shares and 2,850,830 shares of common stock were available for future issuance as of December 31, 2017 and 2016 , respectively, under our ESPP. As of January 1, 2018, an additional 1,871,045 shares of common stock became available for future issuance under our ESPP pursuant to the provisions thereof that automatically increase the share reserve under such plan each year. From time to time, we also grant restricted common stock or restricted stock awards outside of our equity incentive plans to certain employees in connection with acquisitions.

Restricted Stock Award (RSA) and Restricted Stock Unit (RSU) Activity A summary of the activity for our restricted common stock, RSAs and RSUs during the reporting periods and a summary of information related to unvested restricted common stock, RSAs and RSUs and those expected to vest based on the achievement of a performance condition are presented below (in thousands, except per share amounts and contractual life years): Number of Weighted- Weighted- Aggregate Unvested balance — December 31, 2014 8,341 $ 39.57 Granted 16,876 32.25 Vested (2,783 ) 35.66 Cancelled (2,380 ) 41.11 Unvested balance — December 31, 2015 20,054 $ 33.68 Granted 12,711 13.76 Vested (6,222 ) 33.99 Cancelled (6,660 ) 27.17 Unvested balance — December 31, 2016 19,883 $ 22.23 Granted 13,727 12.59 Vested (7,316 ) 21.56 Cancelled (6,277 ) 17.10 Unvested balance — December 31, 2017 20,017 $ 17.09 1.3 $ 284,255 Unvested awards for which the requisite service period has not been rendered and vesting is subject to the achievement of a performance condition — December 31, 2017 4,298 $ 20.22 2.1 $ 61,034 During the year ended December 31, 2015, awards granted includes two cycles of annual refresh grants made to the general employee population. Included in the 12.7 million shares granted during the year ended December 31, 2016 are 3.6 million shares granted to employees from acquisitions consummated in 2016. During the years ended December 31, 2017 , 2016 and 2015 , we issued 1.8 million , 3.0 million and 5.3 million shares, respectively, of restricted common stock, restricted stock awards or restricted stock units to certain employees which vest upon the achievement of certain performance conditions in addition to a continued service relationship with the Company. Stock-Based Compensation We record stock-based compensation based on the fair value as determined on the date granted. We determine the fair value of stock options and shares of common stock to be issued under the ESPP using the Black-Scholes option-pricing model. The fair value of restricted stock units and restricted stock awards equals the market value of the underlying stock on the date of grant. We grant performance-based restricted stock units and restricted stock awards to certain employees which vest upon the achievement of certain performance conditions, subject to the employees’ continued service relationship with us. We assess the probability of vesting at each reporting period and adjust our compensation cost based on this probability assessment. We recognize such compensation expense on a straight-line basis over the service provider’s requisite service period. We determined valuation assumptions as follows: Fair Value of Common Stock We use the listed stock price on the date of grant as the fair value of our common stock. Risk-Free Interest Rate We base the risk-free interest rate used in the Black-Scholes option-pricing model on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent expected term of the options for each option group. Expected Term The expected term represents the period that our stock-based awards are expected to be outstanding. We base the expected term assumption on our historical behavior combined with estimates of post-vesting holding periods. Volatility We determine the price volatility factor based on the historical volatilities of our peer group as we do not have sufficient trading history for our common stock. Dividend Yield The expected dividend assumption is based on our current expectations about our anticipated dividend policy. The following table summarizes the assumptions used in the Black-Scholes option-pricing model to determine the fair value of our common shares under the ESPP: Year Ended December 31, 2017 2016 2015 Fair value of common stock $14.14 - $15.65 $13.12 - $14.12 $19.10 - $35.16 Risk-free interest rate 1.05% - 1.62% 0.38% - 0.79% 0.09% - 0.50% Expected term (in years) 0.5 - 1.0 0.5 - 1.0 0.5 - 1.0 Volatility 29% - 52% 57% - 63% 38% - 42% Dividend yield —% —% —% Stock-based compensation expense related to stock options, ESPP and restricted stock units and awards is included in the consolidated statements of operations as follows (in thousands): Year Ended December 31, 2017 2016 2015 Cost of product revenue $ 2,141 $ 2,092 $ 1,588 Cost of subscription and services revenue 30,515 29,811 29,435 Research and development 56,720 64,755 68,329 Sales and marketing 46,766 57,750 73,286 General and administrative 30,194 43,343 49,793 Restructuring — 1,144 — Total $ 166,336 $ 198,895 $ 222,431 As of December 31, 2017 , total compensation cost related to stock-based awards not yet recognized was $240.9 million , which is expected to be amortized on a straight-line basis over the weighted-average remaining vesting period of approximately 2.2 years. |

The Tax Act makes broad and complex changes to the U.S. tax code. The changes include, but are not limited to, reducing the U.S. federal corporate tax rate from 35% to 21%, imposing a mandatory one-time transition tax on certain unrepatriated earnings of foreign subsidiaries, introducing bonus depreciation that will allow for full expensing of qualified property, eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized. In accordance with the Securities and Exchange Commission Staff Accounting Bulletin No. 118, we provided our best estimate of the impact of the Tax Act in the period ended December 31, 2017 based on our understanding of the Tax Act and guidance available as of the date of this filing. We remeasured our existing net U.S. deferred tax assets using the enacted tax rate and other known significant changes to the tax code. This remeasurement resulted in a total decrease in these assets by $71.7 million which was fully offset by the decrease in valuation allowance. In addition, we recorded a $0.3 million tax benefit related to the release of valuation allowance on AMT credit carryovers because under the Tax Act, existing AMT credits are refundable from 2018 through 2021. A valuation allowance is provided when it is more likely than not that the deferred tax asset will not be realized. Our valuation allowance decreased by approximately $48.7 million during the year ended December 31, 2017 , primarily as a result of the reduction of the Company’s valuation allowance based upon the new enacted federal tax rate and partially offset by additional deferred tax assets recorded during the year as a result of acquisition intangible amortization and net operating loss carryforwards. As of December 31, 2017 , we had federal and state net operating loss carry forwards of approximately $631.5 million and $719.1 million , respectively, available to reduce future taxable income, if any. If not utilized, the federal net operating loss carry forwards will expire from the years ending December 31, 2024 through 2037 while state net operating loss carry forwards will expire from the years ending December 31, 2020 through 2037. We also have federal and state research and development tax credit carry forwards of approximately $24.7 million and $15.7 million , respectively. If not utilized, the federal credit carry forwards will expire in various amounts from the years ended December 31, 2024 through 2037. The state credit will carry forward indefinitely. Utilization of the net operating loss carry forwards and credits may be subject to an annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. As of December 31, 2017 , we had $39.4 million of unrecognized tax benefits, of which if recognized, $1.6 million would affect our effective tax rate. We file income tax returns in U.S. federal, state and foreign jurisdictions. As we have net operating loss carry forwards for U.S. federal and state jurisdictions, the statute of limitations is open for all tax years. For foreign jurisdictions, the tax years open to examination include the years 2013 and forward. We do not expect the unrecognized tax benefits to change significantly over the next 12 months. We recognize both interest and penalties associated with uncertain tax positions as a component of income tax expense. During the year ended December 31, 2017 we recognized interest and penalties of $36,000 . During the years ended December 31, 2016 and 2015 , we recognized a $31,000 decrease and $183,000 increase to interest and penalties, respectively. As of December 31, 2017 and 2016 , our total accrual for interest and penalties was $403,000 and $367,000 , respectively. The ultimate amount and timing of any future cash settlements cannot be predicted with reasonable certainty. A reconciliation of gross unrecognized tax benefits is as follows (in thousands): Year Ended December 31, 2017 2016 2015 Unrecognized tax benefits at the beginning of the period $ 43,637 $ 31,902 $ 21,264 Additions for tax positions related to the current year 10,780 12,435 10,614 Increases related to prior year tax positions — 561 24 Decreases related to prior year tax positions (14,955 ) (1,213 ) — Decreases based on settlements with taxing authorities — (48 ) — Lapse of statute of limitations (75 ) — — Unrecognized tax benefits at the end of the period $ 39,387 $ 43,637 $ 31,902 As of December 31, 2017, we have not made any tax provision for U.S. income taxes and foreign withholding taxes on approximately $31.1 million of earnings in foreign subsidiaries, which we expect to reinvest outside of the U.S. indefinitely. If we were to distribute these earnings to the U.S., we could be subject to U.S. income taxes and foreign withholding taxes. Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. |

Earnings Per Share [Abstract] | |
Net Loss per Share | Net Loss per Share Basic net loss per share is calculated by dividing net loss by the weighted average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of employee share based awards and warrants. Diluted net income per common share is computed giving effect to all potentially dilutive common shares, including common stock issuable upon exercise of stock options, conversion of the Convertible Senior Notes and unvested restricted common stock and stock units. As we had net losses for the years ended December 31, 2017 , 2016 and 2015 , all potential common shares were determined to be anti-dilutive. The following table sets forth the computation of net loss per common share (in thousands, except per share amounts): Year Ended December 31, 2017 2016 2015 Numerator: Net loss $ (303,691 ) $ (480,129 ) $ (539,215 ) Denominator: Weighted average number of shares outstanding—basic and diluted 177,757 163,211 154,120 Net loss per share—basic and diluted $ (1.71 ) $ (2.94 ) $ (3.50 ) The following outstanding options, unvested shares and units, ESPP shares, shares issuable upon the conversion of our Convertible Senior Notes and shares contingently issuable were excluded (as common stock equivalents) from the computation of diluted net loss per common share for the periods presented as their effect would have been anti-dilutive (in thousands): As of December 31, 2017 2016 2015 Options to purchase common stock 4,433 8,085 11,494 Unvested early exercised common shares — — 936 Unvested restricted stock awards and units 20,017 19,883 20,054 Convertible senior notes 15,141 15,141 15,141 iSIGHT earn-out contingently issuable shares — 1,793 — ESPP shares 166 314 210 |

Retirement Benefits [Abstract] | |
Employee Benefit Plan | Employee Benefit Plan 401(k) Plan We have established a 401(k) tax-deferred savings plan (the “401(k) Plan”) which permits participants to make contributions by salary deduction pursuant to Section 401(k) of the Internal Revenue Code of 1986, as amended. All participants’ interests in their deferrals are 100% vested when contributed. We are responsible for administrative costs of the 401(k) Plan and have made no matching contributions into our 401(k) Plan since inception. Under the 401(k) Plan, pre-tax contributions are allocated to each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions. The 401(k) Plan is intended to qualify under Sections 401(a) and 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) Plan and earnings on those contributions are not taxable to the employees until distributed, and all contributions are deductible by us when and if made. |

Segment Reporting [Abstract] | |
Segment and Major Customers Information | Segment and Major Customers Information We conduct business globally and are primarily managed on a geographic basis. Our Chief Executive Officer, who is our chief operating decision maker, reviews financial information presented on a consolidated basis accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. There are no segment managers who are held accountable for operations, operating results, and plans for levels, components, or types of products or services below the consolidated unit level. Accordingly, we are considered to be in a single reportable segment and operating unit structure. Revenue by geographic region based on the billing address is as follows (in thousands): Year Ended December 31, 2017 2016 2015 Revenue: United States $ 494,766 $ 488,623 $ 439,205 EMEA 116,011 102,288 80,960 APAC 104,991 95,285 73,009 Other 35,318 27,918 29,793 Total revenue $ 751,086 $ 714,114 $ 622,967 Long-lived assets by geographic region based on physical location is as follows (in thousands): As of December 31, 2017 2016 Property and Equipment, net: United States $ 60,202 $ 43,214 International 11,155 18,638 Total property and equipment, net $ 71,357 $ 61,852 For the years ended December 31, 2017 , 2016 and 2015 , one distributor represented 19% , 19% and 17% , respectively, and one reseller represented 13% , 12% and 13% , respectively, of the Company's total revenue. .

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation and Consolidation | Basis of Presentation and Consolidation The consolidated financial statements include the accounts of FireEye, Inc. and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany balances and transactions have been eliminated in consolidation. |
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such management estimates include, but are not limited to, the best estimate of selling price for our products, subscriptions and services, commissions expense, bonus expense, future taxable income, contract manufacturer liabilities, litigation and settlement costs and other loss contingencies, fair value of our equity awards, achievement of targets for performance stock units, fair value of the liability and equity components of Convertible Senior Notes and the purchase price allocation of acquired businesses. We base our estimates on historical experience and also on assumptions that we believe are reasonable. Changes in facts or circumstances may cause us to change our assumptions and estimates in future periods, and it is possible that actual results could differ from current or revised future estimates. |
Concentrations | Concentrations Financial instruments that subject us to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. We maintain a substantial portion of our cash and cash equivalents in money market funds invested in U.S. Treasury related obligations. Management believes that these financial institutions are financially sound and, accordingly, are subject to minimal credit risk. Deposits held with banks may exceed the amount of insurance provided on such deposits. Our short-term investments primarily consist of notes and bonds issued by corporate institutions and U.S. Government agencies. All of our investments are highly-rated by credit rating agencies and are issued by organizations with reputable credit, and therefore bear minimal credit risk. Our accounts receivables are primarily derived from a diverse set of customers across various geographical locations. We perform ongoing credit evaluations of our customers and generally do not require collateral on accounts receivable. We maintain an allowance for doubtful accounts for estimated potential credit losses. See Note 15 for information on major customers. We rely primarily on a single contract manufacturer to assemble our products. In some cases we rely on sole suppliers for a certain number of our components. |
Foreign Currency Translation and Transactions | Foreign Currency Translation and Transactions The functional currency of our foreign subsidiaries is the U.S. dollar. We translate all monetary assets and liabilities denominated in foreign currencies into U.S. dollars using the exchange rates in effect at the balance sheet dates and other assets and liabilities using historical exchange rates. Foreign currency denominated revenue and expenses have been re-measured using the average exchange rates in effect during each period. Foreign currency re-measurement gains and losses have been included in other income (expense) |
Cash and Cash Equivalents | Cash and Cash Equivalents We consider all highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. We determine the appropriate classification of our investments at the time of purchase, and evaluate such designation at each balance sheet date. |
Short-term Investments | Short-term Investments We classify our investments in debt and equity securities as available-for-sale and record these investments at fair value. Investments with an original maturity of three months or less at the date of purchase are considered cash equivalents, while all other investments are classified as short-term or long-term based on the nature of the investments, their maturities, and their availability for use in current operations. Unrealized gains and losses are reported as a component of other comprehensive loss. Realized gains and losses are determined based on the specific identification method, and are reflected in our Consolidated Statements of Operations. We regularly review our investment portfolio to identify and evaluate investments that have indicators of possible impairment. Factors considered in determining whether a loss is other-than-temporary include, but are not limited to: the length of time and extent a security’s fair value has been below its cost, the financial condition and near-term prospects of the investee, the credit quality of the security’s issuer, likelihood of recovery and our intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in value. For our debt instruments, we also evaluate whether we have the intent to sell the security or it is more likely than not that we will be required to sell the security before recovery of its cost basis. Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. Fair value is calculated based on publicly available market information or other estimates determined by management. If the cost of an investment exceeds its fair value, we evaluate, among other factors, general market conditions, credit quality of debt instrument issuers, the duration and extent to which the fair value is less than cost and whether we have plans to sell the security, or it is more likely than not that we will be required to sell the security, before recovery. Once a decline in fair value is determined to be other-than-temporary, an impairment charge is recorded to other income (expense) and a new cost basis in the investment is established. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments We define fair value as the price that would be received from selling an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities which are required to be recorded at fair value, we consider the principal or most advantageous market in which to transact and the market-based risk. We apply fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The carrying amounts reported in the consolidated financial statements approximate the fair value for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities due to their short-term nature. |
Accounts Receivable | Accounts Receivable Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on our assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice, each partner’s expected ability to pay and the collection history with each partner, when applicable, to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against the allowance for doubtful accounts when identified. |
Inventories | Inventories Inventories are stated at the lower of cost or net realizable value. Provisions have been made to reduce all slow-moving, obsolete or unusable inventories to their net realizable values. We purchase completed units from contract manufacturers and substantially all of our inventories are finished goods held for use as service replacements. |
Deferred Costs of Revenue | Deferred Costs of Revenue Deferred cost of revenue consists of direct and incremental costs related to product revenue deferred in accordance with the Company’s revenue recognition policy. Deferred cost of revenue that will be realized within the succeeding 12 month period is classified as current, and included in prepaid expenses and other current assets on the consolidated balance sheets. The remaining balance is classified as non-current, and included in deposits and other long-term assets. |
Property and Equipment | Property and Equipment Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally two to five years. The estimated useful lives of property and equipment are described below: Property and Equipment Useful Life Computer equipment and software 2 to 5 years Leasehold improvements Shorter of estimated useful life or remaining lease term Furniture and fixtures 5 years Machinery and equipment 2 to 5 years |
Demonstration Units | Demonstration Units Product demonstration units are included in prepaid expenses and other current assets on the consolidated balance sheets. Demonstration units are recorded at cost and are amortized over the estimated useful life from the date of transfer from inventory, generally 12 months. We generally do not resell units that have been used for demonstration purposes. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets We evaluate events and changes in circumstances that could indicate carrying amounts of long-lived assets may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether or not the carrying value of such assets will be recovered through undiscounted expected future cash flows. If the total of the future undiscounted cash flows is less than the carrying amount of an asset, we record an impairment charge for the amount by which the carrying amount of the assets exceeds the fair value of the asset. |
Business Combinations | Business Combinations We have accounted for all of our acquisitions using the acquisition method. The Company allocates the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired, based on their estimated fair values. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. Critical estimates in valuing certain identifiable assets include, but are not limited to, expected long-term market growth, future expected operating expenses, costs of capital, and appropriate discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and, as a result, actual results may differ from estimates. |
Goodwill and Purchased Intangibles | Goodwill and Purchased Intangibles Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible assets acquired. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has determined that it operates as one reporting unit and has selected December 1 as the date to perform its annual impairment test. In the valuation of its goodwill, the Company must make assumptions regarding estimated future cash flows to be derived from the Company. If these estimates or their related assumptions change in the future, the Company may be required to record impairment for these assets. The first step of the impairment test involves comparing the fair value of the reporting unit to its net book value, including goodwill. If the net book value exceeds its fair value, then the Company would perform the second step of the goodwill impairment test to determine the amount of the impairment loss. The impairment loss would be calculated by comparing the implied fair value of the Company to its net book value. In calculating the implied fair value of the Company’s goodwill, the fair value of the Company would be allocated to all of the other assets and liabilities based on their fair values. The excess of the fair value of the Company over the amount assigned to its other assets and liabilities is the implied fair value of goodwill. An impairment loss would be recognized when the carrying amount of goodwill exceeds its implied fair value. There was no impairment of goodwill recorded for the years ended December 31, 2017 , 2016 or 2015 . Purchased intangible assets with finite lives are carried at cost, less accumulated amortization. Amortization is computed over the estimated useful lives of the respective assets. Purchased intangible assets with indefinite lives are assessed for potential impairment annually, or when events or circumstances indicate that their carrying amounts might be impaired. |
Warranties | Warranties We generally provide a one -year warranty on hardware. We do not accrue for potential warranty claims as a component of cost of product revenue as all product warranty claims are satisfied under our support and maintenance contracts. |
Deferred Revenue | Deferred Revenue Deferred revenue consists of amounts that have been invoiced and for which the Company has the right to bill, but that have not been recognized as revenue. Deferred revenue that will be realized during the succeeding 12 month period is recorded as current, and the remaining deferred revenue is recorded as non-current. |
Contract Manufacturer Liabilities | Contract Manufacturer Liabilities We outsource most of our manufacturing, repair, and supply chain management operations to our independent contract manufacturers and payments to such manufacturers are a significant portion of our product cost of revenue. Although we could be contractually obligated to purchase manufactured products, we generally do not own the manufactured products. Product title transfers from our independent contract manufacturers to us and to our partners upon shipment. Our independent contract manufacturers assemble our products using design specifications, quality assurance programs, and standards that we establish, and they procure components and assemble our products based on our demand forecasts. These forecasts represent our estimates of future demand for our products based upon historical trends and analysis from our sales and product management functions as adjusted for overall market conditions. If the actual component usage and product demand are significantly lower than forecast, we may accrue for costs for contractual manufacturing commitments in excess of our forecasted demand, including costs for excess components or for carrying costs incurred by our contract manufacturers. |
Revenue Recognition | Revenue Recognition We generate revenue from the sales of products, subscriptions, support and maintenance and professional services, primarily through our indirect relationships with our partners as well as end customers through our direct sales force. Our products include operating system software that is integrated into the appliance hardware and is deemed essential to its functionality. As a result, we account for product revenue in accordance with Accounting Standards Codification 605, Revenue Recognition, and all related interpretations, as all of our security appliance deliverables include proprietary operating system software, which together delivers the essential functionality of our products. Our professional services consist primarily of time and materials based contracts, and the revenue is recognized as costs are incurred at amounts represented by the agreed-upon billing amounts. Revenue from fixed-price professional services engagements are recognized under the proportional performance method of accounting. Revenue is recognized when all of the following criteria are met: • Persuasive Evidence of an Arrangement Exists . We rely upon non-cancelable sales agreements and purchase orders to determine the existence of an arrangement. • Delivery has Occurred . We use shipping documents or transmissions of service contract registration codes to verify delivery. • The Fee is Fixed or Determinable . We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction. • Collectability is Reasonably Assured . We assess collectability based on credit analysis and payment history. Our products include security product families that address critical attack vectors, including solutions to detect and prevent attacks targeting networks, email, and endpoint devices. When our solutions are deployed on an appliance, the appliance and the related subscription and support services qualify as separate units of accounting. Therefore, product revenue from these appliances is recognized at the time of shipment. At the time of shipment, product revenue meets the criteria for fixed or determinable fees. In addition, payment from our partners is not contingent on the partners' collection from their end-customers. Our partners do not stock products and do not have any stock rotation rights. We recognize subscription and support and maintenance service revenue ratably over the contractual service period, which is typically one or three years. Professional services revenue, including incident response and related consulting services for our customers who have experienced a cybersecurity breach or who require assistance assessing the vulnerability of their networks, and training services revenue is recognized as the services are rendered. Revenue from the sale of stand-alone software bundled with services is recognized ratably over contract term as we do not have Vendor Specific Objective Evidence, or VSOE, for the undelivered elements. Most of our arrangements, other than renewals of subscriptions and support and maintenance services, are multiple-element arrangements with a combination of product, subscriptions, support and maintenance, and other services. For multiple-element arrangements, we allocate revenue to each unit of accounting based on an estimated selling price at the arrangement inception. The estimated selling price for each element is based upon the following hierarchy: VSOE of selling price, if available, third-party evidence (“TPE”) of selling price, if VSOE of selling price is not available, or best estimate of selling price (“BESP”), if neither VSOE of selling price nor TPE of selling price are available. The total arrangement consideration is allocated to each separate unit of accounting using the relative estimated selling prices of each unit based on the aforementioned selling price hierarchy. We limit the amount of revenue recognized for delivered elements to an amount that is not contingent upon future delivery of additional products or services or meeting of any specified performance conditions. To determine the estimated selling price in multiple-element arrangements, we seek to establish VSOE of selling price using the prices charged for a deliverable when sold separately and, for subscriptions and support and maintenance, based on the renewal rates and discounts offered to partners. If VSOE of selling price cannot be established for a deliverable, we seek to establish TPE of selling price by evaluating similar and interchangeable competitor products or services in standalone arrangements with similarly situated partners. However, as our products contain a significant element of proprietary technology and offer substantially different features and functionality from our competitors, we are unable to obtain comparable pricing of our competitors’ products with similar functionality on a standalone basis. Therefore, we have not been able to obtain reliable evidence of TPE of selling price. If neither VSOE nor TPE of selling price can be established for a deliverable, we establish BESP primarily based on historical transaction pricing. Historical transactions are segregated based on our pricing model and our go-to-market strategy, which include factors such as type of sales channel (reseller, distributor, or end-customer), the geographies in which our products and services were sold (domestic or international), offering type (products, subscriptions or services), and whether or not the opportunity was identified by our sales force or by our partners. In analyzing historical transaction pricing, we evaluate whether a majority of the prices charged for a product, as represented by a percentage of list price, fall within a reasonable range. To further support the best estimate of selling price as determined by the historical transaction pricing or when such information is unavailable, such as when there are limited sales of a new product, we consider the same factors we have established through our pricing model and go-to-market strategy. The determination of BESP is made through consultation with and approval by our management. We have established the estimated selling price of all of our deliverables using BESP. Shipping charges billed to partners are included in revenue and related costs are included in cost of revenue. Sales commissions and other incremental costs to acquire contracts are also expensed as incurred and are recorded in sales and marketing expense. After receipt of a partner order, any amounts billed in excess of revenue recognized are recorded as deferred revenue. |
Advertising Costs | Advertising Costs Advertising costs, which are expensed and included in sales and marketing expense when incurred, were $2.6 million , $3.6 million and $5.1 million during the years ended December 31, 2017 , 2016 and 2015 , respectively. |
Software Development Costs | Software Development Costs The costs to develop internal-use software are subject to capitalization and begin amortizing once the software is substantially ready for use. These costs are included in property and equipment and are generally amortized over 3 years. All other software development costs are expensed as incurred and included in research and development expense on the consolidated statements of operations. |
Stock-Based Compensation | Stock-Based Compensation Compensation expense related to stock-based transactions, including employee and non-employee director awards and our 2013 Employee Stock Purchase Plan (the "ESPP"), is measured and recognized in the financial statements based on fair value. The fair value of each option award is estimated on the grant date using the Black-Scholes option-pricing model and a single option award approach. This model requires that at the date of grant we determine the fair value of the underlying common stock, the expected term of the award, the expected volatility of the price of our common stock, risk-free interest rates, and expected dividend yield of our common stock. The fair value of restricted stock awards and restricted stock units is based on the closing market price of our common stock on the date of grant. The stock-based compensation expense is recognized using a straight-line basis over the requisite service period of the entire awards, which is generally four years , unless the awards are subject to performance conditions, in which case the Company recognizes compensation expense over the requisite service period of each vesting tranche. For performance-based awards, the Company recognizes compensation expense when it becomes probable that the performance criteria set by the Board of Directors will be achieved. Beginning January 1, 2016 with the adoption of ASU 2016-09, we elected to recognize forfeitures as they occur, and no longer estimate a forfeiture rate when calculating the stock-based compensation for our equity awards. Stock-based compensation for the year ended December 31, 2015 was calculated using an estimated forfeiture rate based on an analysis of our actual historical forfeitures. We account for stock options issued to non-employees based on the fair value of the awards determined using the Black-Scholes option-pricing model. The fair value of stock options granted to non-employees is remeasured as the stock options vest, and the resulting change in value, if any, is recognized in the statement of operations during the period the related services are rendered. |
Income Taxes | Income Taxes We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carry forwards. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. We apply the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation settlement. The second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. We recognize interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statements of operations. Accrued interest and penalties are included within other long-term liabilities in the consolidated balance sheets. |
Net Loss Per Share Attributable to Common Stockholders | Net Loss Per Share Attributable to Common Stockholders We calculate our basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for companies with participating securities. Under the two-class method, in periods when the Company has net income, net income attributable to common stockholders is determined by allocating undistributed earnings, calculated as net income less current period convertible preferred stock non-cumulative dividends, between common stock and the convertible preferred stock. In computing diluted net income attributable to common stockholders, undistributed earnings are re-allocated to reflect the potential impact of dilutive securities. The Company’s basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock are considered common stock equivalents, but have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive. |
Convertible Senior Notes | Convertible Senior Notes We allocated the principal amount of the Convertible Senior Notes between its liability and equity components. The carrying amount of the liability component was determined by measuring the fair value of a similar debt instrument of similar credit quality and maturity that did not have the convert feature. The carrying amount of the equity component, representing the embedded conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Convertible Senior Notes as a whole. The equity component was recorded to additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Convertible Senior Notes over the carrying amount of the liability component was recorded as a debt discount, and is being amortized to interest expense using the effective interest method through the first date holders have the right to require us to repurchase all or any portion of their Convertible Senior Notes; the first put date (see Note 8). We allocate the total amount of transaction costs incurred to the liability and equity components using the same proportions as the proceeds from the Convertible Senior Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the liability component of the Convertible Senior Notes, and are being amortized to interest expense using the effective interest method through the first put date. Transaction costs attributable to the equity component were netted with the equity component of the Convertible Senior Notes in additional paid-in capital. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This standard eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (i.e. Step 2 of the current guidance), instead measuring the impairment charge as the excess of the reporting unit's carrying amount over its fair value (i.e. Step 1 of the current guidance). The guidance is effective for us beginning in the first quarter of 2020, and should be applied prospectively. Early adoption is permitted for impairment testing dates after January 1, 2017. The adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This standard changes the definition of a business by requiring that at least one substantive process exist in the acquired entity. It also states that if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets, then the set of transferred assets and activities is not a business. The guidance is effective for us beginning in the first quarter of 2018, and should be applied prospectively. Early adoption is permitted. The adoption of this standard is not expected to have a significant impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard changes the impairment model for most financial assets and certain other instruments by introducing a current expected credit loss (CECL) model. The CECL model is a more forward-looking approach based on expected losses rather than incurred losses, requiring entities to estimate and record losses expected over the remaining contractual life of an asset. The guidance is effective for us beginning in the first quarter of 2020. Early adoption beginning in 2019 is permitted. We are currently evaluating the impact the adoption of this guidance will have on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This standard is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The guidance is effective for us beginning in the first quarter of 2019, and should be applied on a modified retrospective basis. Early adoption is permitted. We expect the adoption of this standard to have a material impact on our consolidated financial statements and related disclosures as it will materially increase our assets and liabilities. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). This standard provides a single model for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. We will adopt this standard effective January 1, 2018. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. We have elected to apply the standard retrospectively to all prior periods presented. The most significant impact of the standard relates to our accounting for intelligence dependent appliance and software license revenue. Revenue related to certain appliances and software licenses not dependent on intelligence, subscription and support offerings, cloud offerings and professional services will remain substantially unchanged. Specifically, under the new standard we will combine intelligence dependent appliances and software licenses with the related intelligence subscription and support as a single performance obligation. As a result, we expect to recognize intelligence dependent appliance and software license revenue ratably, rather than at the time of shipping. Where our contracts contain material right of renewal options, we expect to recognize intelligence dependent appliance and software license revenue over the longer of the life of the related appliance and license or the contractual term. For the contracts where the term is less than the life of the appliance and license, the intelligence subscription and support will be recognized ratably over the contractual term with the allocated value of the material right performance obligations being recognized in the period between the end of the contractual term and the useful life. Where our contracts do not contain material right of renewal options, or the contractual term is longer than the useful life, we expect to recognize intelligence dependent appliance and software license revenue ratably over the contractual term. Due to the complexity of certain of our customer contracts, the actual revenue recognition treatment required under the standard will be dependent on contract-specific terms, and may vary in some instance from the recognition models noted above. We currently believe appliance and software license revenue will be recognized predominantly over the useful life of the appliance and license as most of our appliance and license offerings are intelligence dependent. Incremental costs to obtain a contract will be capitalized and amortized on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained. Most of our commission expenses and related payroll taxes meet this definition. In determining the amortization period, we take into consideration the pattern of transfer to which the asset relates and the renewal periods during which renewal commissions are not commensurate with the initial commissions paid. When initial commissions are not commensurate with renewal commissions, we will recognize the non-commensurate portion of initial commissions over an estimated useful life while the commensurate portion will be recognized over the same period as the initial revenue arrangement to which it relates. Additionally, our appliance related cost of goods sold will be capitalized and amortized on a systematic basis that is consistent with the pattern of transfer to which the asset relates. We expect that adoption of the standard will result in the recognition of additional revenue in fiscal 2017 of $28.0 million and a reduction in revenue in fiscal 2016 of $8.5 million, primarily due to the net change in the recognition of intelligence dependent appliance and software license revenue. In addition, we expect that adoption of the standard will result in a decrease in operating loss of $18.0 million in fiscal 2017 and an increase in operating loss of $5.7 million in fiscal 2016 |
