Organization, Consolidation and Presentation of Financial Statements [Abstract]
Overview and Basis of Presentation	1. Overview and Basis of Presentation Nature of Operations Barracuda Networks, Inc., also referred to in this report as “we,” “our,” “us,” “Barracuda” or “the Company,” is headquartered in Campbell, California, and designs and delivers powerful yet easy-to-use security and storage solutions. We offer cloud-connected solutions that help our customers address security threats, improve network performance and protect and store their data. Our solutions are designed to simplify IT operations for our customers, allowing them to enhance their return on technology investments. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis, including those related to the fair values of stock-based awards, income taxes and contingent liabilities, among others. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates and such differences could be material to our condensed consolidated financial position and results of operations. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP, and follow the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP are condensed or omitted. In management’s opinion, the unaudited condensed financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three months ended May 31, 2015 are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of February 28, 2015 has been derived from audited financial statements at that date but does not include all of the information required by GAAP. The accompanying unaudited condensed consolidated financial statements include the accounts of Barracuda Networks, Inc. and our wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited financial statements and related footnotes included in our most recent Annual Report on Form 10-K. There have been no material changes in our significant accounting policies from those that were disclosed in our Annual Report on Form 10-K for the fiscal year ended February 28, 2015. Foreign Currency We have foreign subsidiaries that operate and sell our products and services in various countries and jurisdictions around the world. As a result, we are exposed to foreign exchange risks. We utilize foreign exchange forward contracts to manage foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily trade receivables, and to reduce the volatility of earnings and cash flows related to foreign currency transactions. The fair values of our contracts as of May 31, 2015 and February 28, 2015 were not significant. The change in the fair value of these foreign currency forward contracts is recorded as gain (loss) in other expense, net in the condensed consolidated statement of operations. For those subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date and revenues and expenses are translated into U.S. dollars using the average exchange rate over the period. Resulting currency translation adjustments are recorded in accumulated other comprehensive loss in the condensed consolidated balance sheets. We recorded net losses resulting from foreign exchange transactions of $0.6 million for the three months ended May 31, 2015. For the three months ended May 31, 2014, the impact of foreign exchange transactions was not material. Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard providing guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. The standard update is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The standard allows for adoption retrospectively or prospectively to all arrangements entered into or materially modified after the effective date. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In February 2015, the FASB issued an accounting standard to improve consolidation guidance for legal entities and affect the consolidation evaluation for reporting organizations. The standard update is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The standard allows for adoption retrospectively or with a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In May 2014, the FASB issued an accounting standard which completes the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improve financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards. The core principle of this update 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 intend to adopt this update as currently issued in the first quarter of fiscal 2018 at which point it will begin to affect us. The standard allows for full retrospective adoption applied to all periods presented or retrospective adoption with the cumulative effect of initially applying this update recognized at the date of initial application. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements.

We consider factors such as the duration, severity and the reason for the decline in value, the potential recovery period and whether we intend to sell. For marketable debt securities, we also consider whether (i) it is more likely than not that we will be required to sell the debt securities before recovery of their amortized cost basis, and (ii) the amortized cost basis cannot be recovered as a result of credit losses. Unrealized losses related to these investments are due to interest rate fluctuations as opposed to changes in credit quality. We do not intend to sell and it is not more likely than not that we would be required to sell these investments before recovery of their amortized cost basis, which may be at maturity. As of May 31, 2015, we have recognized no other-than-temporary impairment loss. The following table summarizes the estimated fair value of our investments in marketable debt securities by contractual maturities (in thousands): As of Due in 1 year $ 11,535 Due in 1 year through 5 years 22,643 Due in 5 years through 10 years 1,301 Due after 10 years 4,361 $ 39,840 Fair Value Measurements We determine fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value: Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3: Inputs are unobservable inputs based on our assumptions. Cash equivalents and marketable equity securities are classified within Level 1 because they are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Marketable debt securities and derivative assets are classified within Level 2 if the investments are valued using model driven valuations which use observable inputs such as quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models. We estimated the fair value of our Level 3 contingent consideration liability based on a weighted probability assessment of achieving the milestones associated with the contingent consideration related to our acquisition of C2C Systems Limited. Significant increases (decreases) in the probability assumptions in isolation would result in a significantly higher (lower) fair value measurement. In developing these estimates, we considered unobservable inputs that are supported by little or no market activity and reflect our own assumptions. The following table summarizes the change in fair value of our Level 3 contingent consideration liability (in thousands): Balance as of February 28, 2015 $ 3,028 Total remeasurement recognized in earnings 36 Balance as of May 31, 2015 $ 3,064 For the three months ended May 31, 2015, the contingent consideration remeasurement was recognized within research and development and sales and marketing expenses in our condensed consolidated statement of operations.

Investment in Non-marketable Equity Security In October 2011, we acquired stock in a privately held company for $750,000, which represented an ownership interest of approximately 24%. In October 2014, we acquired additional shares of stock in the privately held company for $500,000 to maintain our percentage ownership interest. Under the equity method of accounting, we recognize our proportional share of earnings and losses of the investee in our financial statements and adjust the carrying amount of our investment accordingly. For the three months ended May 31, 2015 and 2014, our proportionate share of the investee’s earnings and losses was not material. The investment is classified in other non-current assets in our condensed consolidated balance sheets. Accumulated Other Comprehensive Income (Loss) The components of accumulated other comprehensive income (loss) (“AOCI”), net of tax, were as follows (in thousands): Foreign Currency Translation Adjustments Unrealized Gains (Losses) on Available-for- Sale Investments Total Balance as of February 28, 2015 $ (4,225 ) $ (8 ) $ (4,233 ) Other comprehensive income (loss) before reclassifications (51 ) 1,855 1,804 Amounts reclassified from AOCI — (3 ) (3 ) Other comprehensive income (loss) (51 ) 1,852 1,801 Balance as of May 31, 2015 $ (4,276 ) $ 1,844 $ (2,432 )

Options granted are exercisable for periods not to exceed 10 years. Options and RSUs granted typically vest over four years contingent upon employment or service with us on the vesting date. As of May 31, 2015, net of forecasted forfeitures, there was $23.4 million of unrecognized compensation cost related to outstanding stock options, expected to be recognized over a weighted-average period of 2.87 years and $43.7 million of unrecognized compensation cost related to unvested RSUs, expected to be recognized over a weighted-average period of 3.27 years. To the extent the actual forfeiture rate is different from what management has anticipated, stock-based compensation expense related to these equity awards will be different from management’s expectations. Total stock-based compensation expense has been classified as follows in the accompanying condensed consolidated statements of operations (in thousands): Three Months Ended May 31, 2015 2014 Cost of revenue $ 211 $ 52 Research and development 1,835 748 Sales and marketing 1,550 582 General and administrative 2,948 1,700 $ 6,544 $ 3,082

Income Tax Disclosure [Abstract]
Income Taxes	5. Income Taxes For the three months ended May 31, 2015 and 2014, we recorded an income tax provision of $2.4 million and $0.6 million, respectively. In fiscal 2015, we established a valuation allowance against a significant portion of our deferred tax assets, including U.S. federal and state deferred tax assets and certain foreign deferred tax assets, because realization of these tax benefits through future taxable income did not meet the more-likely-than-not threshold. We intend to maintain the valuation allowances until sufficient positive evidence exists to support its reversal. The difference between the income tax provision that would be derived by applying the statutory rate to our before tax loss for the three months ended May 31, 2015 and the income tax provision actually recorded is primarily due to the temporary differences we did not benefit from during the period due to our valuation allowance, as well as non-deductible stock-based compensation expense and other currently non-deductible items.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	7. Commitments and Contingencies Legal Matters In late 2011, following a voluntary internal review of our compliance with U.S. export control and sanctions laws, our management team became aware that certain of our physical appliances had been sold indirectly into embargoed countries via our distributors and resellers, potentially in violation of U.S. export control and economic sanctions laws. In addition, certain of our solutions incorporate encryption components and may be exported from the United States only with the required approvals; in the past, we may have exported products prior to receiving these required authorizations. After completion of a comprehensive internal investigation conducted by outside counsel, we submitted voluntary disclosures regarding these matters to the U.S. Commerce Department, Bureau of Industry and Security (“BIS”), and to the U.S. Treasury Department, Office of Foreign Assets Control (“OFAC”). These disclosures summarized potential violations of export controls and economic sanctions laws, including reexports by third parties and provision of services to end users in embargoed countries including Iran, Sudan and Syria. We agreed to a settlement with OFAC in May 2015 pursuant to which we agreed to pay $38,930 as consideration for the final resolution of all issues related to the voluntary disclosure that we submitted to OFAC. We received a Proposed Charging Letter from BIS on August 21, 2014, which asserts certain export violations against us and our UK subsidiary. Based on discussions with BIS, we expect a one-time monetary penalty to be imposed, and do not currently expect any criminal charges, denial of export privileges or ongoing monitoring actions. We intend to continue cooperating with BIS in an effort to resolve this matter. However, at this time, we are unable to estimate the timing or amount of any final resolution. On January 23, 2015, Wetro Lan LLC (“Wetro Lan”) filed a lawsuit against us in the U.S. District Court for the Eastern District of Texas, Marshall Division, Wetro Lan LLC v. Barracuda Networks, Inc., Case No. 2:15-CV-46, alleging that certain of our products infringe U.S. Pat. No. 6,795,918. Wetro Lan has asserted similar claims against other companies. We intend to vigorously defend the lawsuit and we are currently unable to estimate a possible loss or range of possible loss, if any. On June 3, 2015, Verifire Network Solutions, LLC (“Verifire”) filed a lawsuit against us in the U.S. District Court for the Eastern District of Texas, Marshall Division, Verifire Network Solutions, LLC v. Barracuda Networks, Inc., Case No. 2:15-CV-928, alleging that certain of our products infringe U.S. Pat. No. 8,463,727. Verifire has asserted similar claims against other companies. This matter is in its early stages, but we intend to vigorously defend the lawsuit. Given the early stage of the litigation, we are unable to estimate a possible loss or range of possible loss, if any. From time to time, we are party to litigation and subject to claims that arise in the ordinary course of our business, including actions with respect to employment claims and other matters. Although the results of litigation and claims are inherently unpredictable, we believe that the final outcome of such matters will not have a material adverse effect on our business, consolidated financial position, results of operations or cash flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Barracuda Networks, Inc., also referred to in this report as “we,” “our,” “us,” “Barracuda” or “the Company,” is headquartered in Campbell, California, and designs and delivers powerful yet easy-to-use security and storage solutions. We offer cloud-connected solutions that help our customers address security threats, improve network performance and protect and store their data. Our solutions are designed to simplify IT operations for our customers, allowing them to enhance their return on technology investments.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We evaluate our estimates on an ongoing basis, including those related to the fair values of stock-based awards, income taxes and contingent liabilities, among others. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates and such differences could be material to our condensed consolidated financial position and results of operations.
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP, and follow the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP are condensed or omitted. In management’s opinion, the unaudited condensed financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three months ended May 31, 2015 are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of February 28, 2015 has been derived from audited financial statements at that date but does not include all of the information required by GAAP. The accompanying unaudited condensed consolidated financial statements include the accounts of Barracuda Networks, Inc. and our wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited financial statements and related footnotes included in our most recent Annual Report on Form 10-K. There have been no material changes in our significant accounting policies from those that were disclosed in our Annual Report on Form 10-K for the fiscal year ended February 28, 2015.
Foreign Currency	Foreign Currency We have foreign subsidiaries that operate and sell our products and services in various countries and jurisdictions around the world. As a result, we are exposed to foreign exchange risks. We utilize foreign exchange forward contracts to manage foreign currency risk associated with foreign currency denominated monetary assets and liabilities, primarily trade receivables, and to reduce the volatility of earnings and cash flows related to foreign currency transactions. The fair values of our contracts as of May 31, 2015 and February 28, 2015 were not significant. The change in the fair value of these foreign currency forward contracts is recorded as gain (loss) in other expense, net in the condensed consolidated statement of operations. For those subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated into U.S. dollar equivalents at the exchange rate in effect on the balance sheet date and revenues and expenses are translated into U.S. dollars using the average exchange rate over the period. Resulting currency translation adjustments are recorded in accumulated other comprehensive loss in the condensed consolidated balance sheets. We recorded net losses resulting from foreign exchange transactions of $0.6 million for the three months ended May 31, 2015. For the three months ended May 31, 2014, the impact of foreign exchange transactions was not material.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard providing guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. The standard update is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The standard allows for adoption retrospectively or prospectively to all arrangements entered into or materially modified after the effective date. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In February 2015, the FASB issued an accounting standard to improve consolidation guidance for legal entities and affect the consolidation evaluation for reporting organizations. The standard update is effective for fiscal years beginning after December 15, 2015 and interim periods within those years and early adoption is permitted. The standard allows for adoption retrospectively or with a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements. In May 2014, the FASB issued an accounting standard which completes the joint effort by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and improve financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards. The core principle of this update 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 intend to adopt this update as currently issued in the first quarter of fiscal 2018 at which point it will begin to affect us. The standard allows for full retrospective adoption applied to all periods presented or retrospective adoption with the cumulative effect of initially applying this update recognized at the date of initial application. We are currently evaluating the impact of adopting this update on our condensed consolidated financial statements.
Fair Value Measurements	Fair Value Measurements We determine fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value: Level 1: Inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3: Inputs are unobservable inputs based on our assumptions. Cash equivalents and marketable equity securities are classified within Level 1 because they are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Marketable debt securities and derivative assets are classified within Level 2 if the investments are valued using model driven valuations which use observable inputs such as quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models. We estimated the fair value of our Level 3 contingent consideration liability based on a weighted probability assessment of achieving the milestones associated with the contingent consideration related to our acquisition of C2C Systems Limited. Significant increases (decreases) in the probability assumptions in isolation would result in a significantly higher (lower) fair value measurement. In developing these estimates, we considered unobservable inputs that are supported by little or no market activity and reflect our own assumptions.
Investment in Non-marketable Equity Security	Investment in Non-marketable Equity Security In October 2011, we acquired stock in a privately held company for $750,000, which represented an ownership interest of approximately 24%. In October 2014, we acquired additional shares of stock in the privately held company for $500,000 to maintain our percentage ownership interest. Under the equity method of accounting, we recognize our proportional share of earnings and losses of the investee in our financial statements and adjust the carrying amount of our investment accordingly.
Segment Information	Our chief operating decision maker reviews the financial information presented on a consolidated basis for purposes of allocating resources and evaluating our financial performance. Accordingly, we have determined that we operate in a single reporting segment.
