Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
BASIS OF PRESENTATION | BASIS OF PRESENTATION The accompanying unaudited interim consolidated financial statements have been prepared by NetScout Systems, Inc. (NetScout or the Company). Certain information and footnote disclosures normally included in financial statements prepared under United States generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the Company's financial position, results of operations and cash flows. The year-end consolidated balance sheet data was derived from the Company's audited financial statements, but does not include all disclosures required by GAAP. The results reported in these unaudited interim consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. All significant intercompany accounts and transactions are eliminated in consolidation. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 filed with the Securities and Exchange Commission on May 21, 2018. Certain amounts for the three and six months ended September 30, 2017 have been reclassified to conform to the current period presentation. These reclassifications had no effect on the reported results of operations. Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15). This ASU clarifies the accounting treatment for implementation costs for cloud computing arrangements (hosting arrangements) that is a service contract. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. The Company adopted ASU 2018-15 effective July 1, 2018. The adoption has had an immaterial impact to the consolidated financial statements for the three months ended September 30, 2018 . In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU adds, modifies and clarifies several disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This guidance is effective for fiscal years ending after December 15, 2020. ASU 2018-14 is effective for NetScout beginning April 1, 2021. Early adoption is permitted. The Company is currently assessing the effect that ASU 2018-14 will have on its financial position, results of operations, and disclosures. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 adds, modifies and removes several disclosure requirements relative to the three levels of inputs used to measure fair value in accordance with Topic 820, Fair Value Measurement. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. ASU 2018-13 is effective for NetScout beginning April 1, 2020. Early adoption is permitted. The Company is currently assessing the effect that ASU 2018-13 will have on its financial position, results of operations, and disclosures. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income (ASU 2018-02). ASU 2018-02 amends ASC 220, Income Statement - Reporting Comprehensive Income, to allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (Tax Legislation). In addition, under the ASU 2018-02, the Company may be required to provide certain disclosures regarding stranded tax effects. ASU 2018-02 is effective for years beginning after December 15, 2018, and interim periods within those fiscal years. ASU 2018-02 is effective for NetScout beginning April 1, 2019. Early adoption is permitted. The Company does not believe the adoption of ASU 2018-02 will have a material impact on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). ASU 2017-12 provides guidance to better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This standard is effective for financial statements issued for fiscal years beginning after December 15, 2018, with early adoption permitted. ASU 2017-12 is effective for the Company beginning April 1, 2019. The Company is currently assessing the potential impact of the adoption of ASU 2017-12 on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Section A - Leases: Amendments to the FASB Accounting Standards Codification (ASU 2016-02), its new standard on accounting for leases. This update requires the recognition of leased assets and lease obligations by lessees for those leases currently classified as operating leases under existing lease guidance. Short term leases with a term of 12 months or less are not required to be recognized. The update also requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements and ASU 2018-10, Codification Improvements to Topic 842, Leases. ASU 2016-02 and the subsequent modifications are identified as ASC 842. ASC 842 will be effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal years. ASC 842 requires a modified retrospective transition method with the option to elect a package of practical expedients. Early adoption is permitted. The Company expects the adoption to increase the assets and liabilities recorded on its consolidated balance sheet and increase the level of disclosures related to leases. In addition, the Company is in the process of identifying appropriate changes to its accounting policies, information technology systems, business processes, and related internal controls to support recognition and disclosure requirements under ASC 842. The Company expects to design any necessary changes to its business processes, controls and systems in the near future and implement the changes over the remainder of fiscal year 2019. ASC 842 is effective for the Company beginning April 1, 2019. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (Topic 606). Topic 606 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The Company adopted Topic 606 as of April 1, 2018 using the modified retrospective transition method. Please refer to Note 2, "Revenue Recognition" for further details. |

Revenue from Contract with Customer [Abstract] | |
REVENUE RECOGNITION | REVENUE RECOGNITION Revenue from Contracts with Customers In May 2014, the FASB issued Topic 606, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Topic 606 replaced most existing revenue recognition guidance under GAAP. The new standard introduces a five-step process to be followed in determining the amount and timing of revenue recognition. It also provides guidance on accounting for costs incurred to obtain or fulfill contracts with customers and establishes disclosure requirements which are more extensive than those required under prior GAAP. Topic 606 became effective for the Company on April 1, 2018. The Company elected to use the modified retrospective transition approach. Therefore, the comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. Revenue Recognition Policy The Company exercises judgment and uses estimates in connection with determining the amounts of product and service revenues to be recognized in each accounting period. The Company derives revenues primarily from the sale of network management tools and security solutions for service provider and enterprise customers, which include hardware, software and service offerings. The majority of its product sales consist of hardware products with embedded software that are essential to providing customers the intended functionality of the solutions. The Company also sells stand-alone software solutions to provide customers with enhanced functionality. In addition, the Company sells hardware bundled with a software license. The Company accounts for revenue once a legally enforceable contract with a customer has been approved by the parties and the related promises to transfer products or services have been identified. A contract is defined by the Company as an arrangement with commercial substance identifying payment terms, each party’s rights and obligations regarding the products or services to be transferred and collection is probable. Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Revenue is recognized when control of the products or services are transferred to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for products and services. Product revenue is recognized upon shipment, provided a legally enforceable contract exists, control has passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software, and collection of the related receivable is probable. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to installation and acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled. The Company's service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support, stand-ready software-as-a-service (SAAS) and other professional services including consulting and training. The Company generally provides software and/or hardware support as part of product sales. Revenue related to the initial bundled software and hardware support is recognized ratably over the support period. In addition, customers can elect to purchase extended support agreements for periods after the initial software/hardware warranty expiration. Support services generally include rights to unspecified upgrades (when and if available), telephone and internet-based support, updates, bug fixes and hardware repair and replacement. Consulting services are recognized upon delivery or completion of performance depending on the terms of the underlying contract. SAAS services are recognized ratably over the contract term beginning on the commencement of services. Reimbursements of out-of-pocket expenditures incurred in connection with providing consulting services are included in services revenue, with the offsetting expense recorded in cost of service revenue. Training services include on-site and classroom training. Training revenues are recognized upon delivery of the training. Generally, the Company's contracts are accounted for individually. However, when contracts are closely interrelated and dependent on each other, it may be necessary to account for two or more contracts as one to reflect the substance of the group of contracts. Bundled arrangements are concurrent customer purchases of a combination of our product and service offerings that may be delivered at various points in time. The Company allocates the transaction price among the performance obligations in an amount that depicts the relative standalone selling prices (SSP) of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. The Company uses a range of amounts to estimate SSP when it sells each of the products and services separately based on the element’s historical pricing. The Company also considers its overall pricing objectives and practices across different sales channels and geographies, and market conditions. Generally, the Company has established SSP for a majority of its service elements based on historical standalone sales. In certain instances, the Company has established SSP for services based upon an estimate of profitability and the underlying cost to fulfill those services. Further, for certain service engagements, the Company considers quoted prices as part of multi element arrangements of those engagements as a basis for establishing SSP. SSP has been established for product elements as the average or median selling price the element was recently sold for, whether sold alone or sold as part of a multiple element transaction. The Company reviews sales of the product elements on a quarterly basis and updates, when appropriate, its SSP for such elements to ensure that it reflects recent pricing experience. The Company's products are distributed through its direct sales force and indirect distribution channels through alliances with resellers and distributors. Revenue arrangements with resellers and distributors are recognized on a sell-in basis; that is, product is delivered to the reseller or distributor. The Company records consideration given to a reseller or distributor as a reduction of revenue to the extent they have recorded revenue from the reseller or distributor. With limited exceptions, the Company's return policy does not allow product returns for a refund. Returns have been insignificant to date. In addition, the Company has a history of successfully collecting receivables from its resellers and distributors. Financial Statement Impact of Adoption The cumulative impact of applying Topic 606 to all contracts with outstanding performance obligations as of April 1, 2018 was recorded as an adjustment to retained earnings as of the adoption date. As a result of applying the modified retrospective approach to adopt the new standard, the following adjustments were made to accounts on the consolidated balance sheet at April 1, 2018 (in thousands): Balance at March 31, 2018 Adjustments from Adopting Topic 606 Balance at April 1, 2018 ASSETS: Accounts receivable and unbilled costs $ 213,438 $ 1,195 $ 214,633 Prepaid expenses and other current assets 33,502 4,626 38,128 Other assets 12,866 4,748 17,614 LIABILITIES: Deferred revenue and customer deposits 301,925 (30,227 ) 271,698 Deferred tax liability 151,563 7,899 159,462 Long-term deferred revenue and customer deposits 91,409 (1,252 ) 90,157 STOCKHOLDERS' EQUITY: Retained earnings 396,493 34,149 430,642 In connection with the adoption of Topic 606, the Company increased its retained earnings by $34.1 million , due to uncompleted contracts at April 1, 2018, of which $34.9 million of revenue will not be recognized in future periods under the new standard. The Company capitalized $7.1 million of incremental sales commission costs on the adoption date directly related to obtaining customer contracts and is amortizing these costs as it satisfies the underlying performance obligations, which for certain contracts can include anticipated renewal periods. As of April 1, 2018, the acceleration of revenue that was deferred under prior guidance was primarily attributable to no longer requiring the separation of promised goods or services, such as software licenses, technical support, specified and unspecified upgrade rights on the basis of vendor specific objective evidence, and the impact of allocating the transaction price to the software performance obligations in the contract on a relative basis using standalone selling price rather than allocating under the residual method, which allocates the entire arrangement discount to the delivered performance obligations. In addition, revenue from perpetual licenses and associated hardware with extended payment terms and term licenses are now recognized when control is transferred to the customer, the point in time when the customer can use and benefit from the license. Previously the Company recognized revenue over the term of the agreements as payments became due or earlier if prepaid. The net change in deferred income taxes of $7.9 million is primarily due to the deferred tax effects resulting from the adjustment to retained earnings for the cumulative effect of applying Topic 606 to active contracts as of the adoption date. Impact of Topic 606 on Financial Statement Line Items The impact of adoption of Topic 606 on the Company's consolidated balance sheet at September 30, 2018 and on the Company's consolidated statement of operations for the three and six months ended September 30, 2018 was as follows (in thousands): September 30, 2018 As Reported Balance without Adoption of Topic 606 Effect of Change Higher (Lower) ASSETS: Accounts receivable and unbilled costs $ 184,156 $ 181,123 $ 3,033 Inventories and deferred costs 30,985 31,231 (246 ) Prepaid expenses and other current assets 27,429 23,845 3,584 Other assets 20,006 14,315 5,691 LIABILITIES: Deferred revenue and customer deposits 230,098 248,632 (18,534 ) Deferred tax liability 135,738 129,484 6,254 Long-term deferred revenue and customer deposits 77,135 88,683 (11,548 ) STOCKHOLDERS' EQUITY: Retained earnings 341,710 314,246 27,464 Three Months Ended September 30, 2018 Six Months Ended September 30, 2018 As Reported Balance without Adoption of Topic 606 Effect of Change Higher (Lower) As Reported Balance without Adoption of Topic 606 Effect of Change Higher (Lower) Total revenues $ 223,797 $ 215,993 $ 7,804 $ 428,908 $ 419,346 $ 9,562 Total cost of revenue 63,980 63,734 246 126,007 125,761 246 Sales and marketing expense 72,051 71,672 379 150,183 149,197 986 Income tax provision (2,635 ) (3,286 ) 651 (21,877 ) (23,522 ) 1,645 Net loss (26,428 ) (32,956 ) 6,528 (88,932 ) (95,617 ) 6,685 Basic net loss per share $ (0.34 ) $ (0.42 ) $ 0.08 $ (1.12 ) $ (1.20 ) $ 0.08 Diluted net loss per share $ (0.34 ) $ (0.42 ) $ 0.08 $ (1.12 ) $ (1.20 ) $ 0.08 The adoption of Topic 606 had no impact to net cash provided by or used in operating, investing and financing activities on the Company’s consolidated statements of cash flows during the six months ended September 30, 2018 . Performance Obligations Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. The transaction price is allocated among performance obligations in bundled contracts in an amount that depicts the relative standalone selling prices of each obligation. For contracts involving distinct hardware and software licenses, the performance obligations are satisfied at a point in time when control is transferred to the customer. For standalone maintenance and post-contract support (PCS) the performance obligation is satisfied ratably over the contract term as a stand-ready obligation. For consulting and training services, the performance obligation may be satisfied over the contract term as a stand-ready obligation, satisfied over a period of time as those services are delivered, or satisfied at the completion of the service when control has transferred or the services have expired unused. Payments for hardware, software licenses, one-year maintenance, PCS and consulting services, are typically due up front with payment terms of 30 to 90 days. However, the Company does have contracts pursuant to which billings occur ratably over a period of years following the transfer of control for the contracted performance obligations. Payments on multi-year maintenance, PCS and consulting services are typically due in annual installments over the contract term. The Company did not have any material variable consideration such as obligations for returns, refunds or warranties at September 30, 2018 . At September 30, 2018 , the Company had total deferred revenue of $307.2 million , which represents the aggregate total contract price allocated to undelivered performance obligations. The Company expects to recognize $230.1 million, or 75% , of this revenue during the next 12 months, and expects to recognize the remaining $77.1 million, or 25% , of this revenue thereafter. Because of NetScout's revenue recognition policies, there are circumstances for which the Company does not recognize revenue relating to sales transactions that have been billed, but the related account receivable has not been collected. While the receivable represents an enforceable obligation, for balance sheet presentation purposes, the Company has not recognized the deferred revenue or the related account receivable and no amounts appear in the consolidated balance sheets for such transactions. The aggregate amount of unrecognized accounts receivable and deferred revenue was $10.0 million and $20.0 million at September 30, 2018 and March 31, 2018, respectively. NetScout expects that the amount of billed and unbilled deferred revenue will change from quarter to quarter for several reasons, including the specific timing, duration and size of large customer support and service agreements, varying billing cycles of such agreements, the specific timing of customer renewals, and foreign currency fluctuations. The Company did not have any significant financing components, or variable consideration or performance obligations satisfied in a prior period recognized during the three and six months ended September 30, 2018 . Contract Balances The Company receives payments from customers based on a billing schedule as established by the Company’s contracts. Contract assets relate to performance obligations in advance of scheduled billings. Upon adoption, the Company recorded unbilled accounts receivable representing the right to consideration in exchange for goods or services that have been transferred to a customer conditional on the passage of time. The Company did not record any contract assets upon adoption. Deferred revenue relates to payments received in advance of performance under the contract. The following table provides information about contract assets and liabilities (in thousands): April 1, 2018 September 30, 2018 Increase/ (Decrease) ASSETS: Customer accounts receivable $ 205,299 $ 190,903 $ (14,396 ) Unbilled receivables 4,338 4,402 64 Other receivables 4,996 3,287 (1,709 ) Long-term unbilled receivables 2,254 3,754 1,500 $ 216,887 $ 202,346 $ (14,541 ) LIABILITIES: Deferred revenue $ 271,698 $ 230,098 $ (41,600 ) Deferred revenue, long-term 90,157 77,135 (13,022 ) $ 361,855 $ 307,233 $ (54,622 ) Changes in deferred revenue during the six months ended September 30, 2018 were as follows (in thousands): Balance at April 1, 2018 $ 361,855 Revenue recognized in the period (206,512 ) Additions to customer deposits and contract liabilities 159,265 Reclassifications and other adjustments 594 Divestiture of the HNT tools business (7,969 ) Balance at September 30, 2018 $ 307,233 Costs to Obtain Contracts The Company has determined that the only significant incremental costs incurred to obtain contracts with clients within the scope of Topic 606 are sales commissions paid to its associates. Sales commissions are recorded as an asset and amortized to expense ratably over the remaining performance periods of the related contracts with remaining performance obligations. The Company applies the practical expedient in Topic 606 and expenses costs as incurred for sales commissions when the amortization period would have been one year or less. At September 30, 2018 , the consolidated balance sheet included $5.6 million in assets related to sales commissions to be expensed in future periods. A balance of $3.6 million was included in prepaid expenses and other current assets, and a balance of $2.0 million was included as other assets in the Company's consolidated balance sheet at September 30, 2018 . During the three and six months ended September 30, 2018 , the Company recognized $1.8 million and $3.3 million of amortization related to this sales commission asset, which is included in the sales and marketing expense line in the Company's consolidated statements of operations. |

Risks and Uncertainties [Abstract] | |
CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS | CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of investments, trade accounts receivable and accounts payable. The Company's cash, cash equivalents, and marketable securities are placed with financial institutions with high credit standings. At September 30, 2018 the Company had one direct customer, Verizon, who accounted for more than 10% of the accounts receivable balance, while no indirect channel partner accounted for more than 10% of the accounts receivable balance. At March 31, 2018 , the Company had no direct customers or indirect channel partners which accounted for more than 10% of the accounts receivable balance. During the three and six months ended September 30, 2018 and September 30, 2017 , no direct customers or indirect channel partners accounted for more than 10% of the Company's total revenue. As disclosed parenthetically within the Company's consolidated balance sheet, the Company has receivables from related parties included within prepaid expenses and other current assets that represent a concentration of credit risk of $1.5 million and $3.2 million at September 30, 2018 and March 31, 2018 , respectively. Historically, the Company has not experienced any significant failure of its customers' ability to meet their payment obligations nor does the Company anticipate material non-performance by its customers in the future; accordingly, the Company does not require collateral from its customers. However, if the Company's assumptions are incorrect, there could be an adverse impact on its allowance for doubtful accounts. |

Fair Value Disclosures [Abstract] | |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant non-observable inputs. The following tables present the Company's financial assets and liabilities measured on a recurring basis using the fair value hierarchy at September 30, 2018 and March 31, 2018 (in thousands): Fair Value Measurements at September 30, 2018 Level 1 Level 2 Level 3 Total ASSETS: Cash and cash equivalents $ 332,183 $ — $ — $ 332,183 U.S. government and municipal obligations 43,406 19,067 — 62,473 Commercial paper — 54,701 — 54,701 Corporate bonds 2,761 — — 2,761 Derivative financial instruments — 16 — 16 Contingent consideration — — 2,267 2,267 $ 378,350 $ 73,784 $ 2,267 $ 454,401 LIABILITIES: Contingent purchase consideration $ — $ — $ (5,017 ) $ (5,017 ) Derivative financial instruments — (220 ) — (220 ) $ — $ (220 ) $ (5,017 ) $ (5,237 ) Fair Value Measurements at March 31, 2018 Level 1 Level 2 Level 3 Total ASSETS: Cash and cash equivalents $ 369,821 $ — $ — $ 369,821 U.S. government and municipal obligations 14,513 27,673 — 42,186 Commercial paper — 33,003 — 33,003 Corporate bonds 2,752 — — 2,752 Derivative financial instruments — 122 — 122 $ 387,086 $ 60,798 $ — $ 447,884 LIABILITIES: Contingent purchase consideration $ — $ — $ (5,464 ) $ (5,464 ) Derivative financial instruments — (40 ) — (40 ) $ — $ (40 ) $ (5,464 ) $ (5,504 ) This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including marketable securities and derivative financial instruments. The Company's Level 1 investments are classified as such because they are valued using quoted market prices or alternative pricing sources with reasonable levels of price transparency. The Company's Level 2 investments are classified as such because fair value is calculated using market observable data for similar but not identical instruments, or a discounted cash flow model using the contractual interest rate as compared with the underlying interest yield curve. The Company classifies municipal obligations as level 2 because the fair values are determined using quoted prices from markets the Company considers to be inactive. Commercial paper is classified as Level 2 because the Company uses market information from similar but not identical instruments and discounted cash flow models based on interest rate yield curves to determine fair value. The Company's derivative financial instruments consist of forward foreign exchange contracts and are classified as Level 2 because the fair values of these derivatives are determined using models based on market observable inputs, including spot prices for foreign currencies and credit derivatives, as well as an interest rate factor. The Company's Level 3 assets consist of contingent consideration related to the divestiture of the Company's handheld network test (HNT) tools business in September 2018. The contingent consideration of $2.3 million represents potential future earnout payments to the Company of up to $4.0 million over two years that are contingent on the HNT tools business achieving certain milestones. The fair value of the contingent consideration was recognized on the acquisition date and was measured using unobservable (Level 3) inputs. The $2.3 million of contingent consideration is included in other assets within the Company’s consolidated balance sheet at September 30, 2018. The Company's Level 3 liabilities consist of contingent purchase consideration. The fair value of contingent purchase consideration related to the acquisition of Simena LLC (Simena) in November 2011 for future consideration to be paid to the seller is $5.0 million and $4.9 million at September 30, 2018 and March 31, 2018 respectively. The contingent purchase consideration is included as a contingent liability within accrued other in the Company's consolidated balance sheet at September 30, 2018 and March 31, 2018 . The Company's contingent purchase consideration at March 31, 2018 included $523 thousand related to the acquisition of certain assets and liabilities of Efflux Systems, Inc. (Efflux) in the second quarter of fiscal year 2018. The contingent purchase consideration was released from escrow to the sellers in July 2018. The following table sets forth a reconciliation of changes in the fair value of the Company's Level 3 financial assets and liabilities for the six months ended September 30, 2018 (in thousands): Contingent Purchase Consideration Contingent Consideration Balance at March 31, 2018 $ (5,464 ) $ — Contingent consideration pursuant to divestiture of HNT tools business — 2,257 Change in fair value of contingent consideration (76 ) 10 Payments of contingent consideration 523 — Balance at September 30, 2018 $ (5,017 ) $ 2,267 Deal-related compensation expense and accretion charges related to the contingent purchase consideration for the six months ended September 30, 2018 was $76 thousand and was included within research and development expense.

ACQUISITIONS & DIVESTITURES | ACQUISITIONS & DIVESTITURES HNT Tools Business Divestiture On September 14, 2018 (the HNT Divestiture Date), the Company divested its HNT tools business for cash proceeds of $1.3 million and potential future earnout payments of up to $4.0 million over two years that are contingent on the HNT tools business achieving certain milestones. The fair value of the contingent consideration in the amount of $2.3 million was recognized on the HNT Divestiture Date and was measured using unobservable (Level 3) inputs. The $2.3 million of consideration is included in other assets within the Company’s consolidated balance sheet at September 30, 2018. Changes in the fair value of the contingent consideration in future periods will be recorded in the Company’s results in the period of the change. The contingent consideration is presented as a non-cash investing activity on the unaudited consolidated statement of cash flows. The Company transferred $4.5 million along with net liabilities of the HNT tools business related to a working capital adjustment during the three months ended September 30, 2018. The Company recorded a loss on the divestiture for the quarter ended September 30, 2018 totaling $9.2 million , which included $1.3 million of transaction costs and $0.5 million of incentive compensation payable to the HNT tools business employees negotiated as part of the sale. In connection with the divestiture, the Company has entered into a transitional services agreement with the buyer to provide certain services for a period of up to eighteen months. The Company determined that the sale of the HNT tools business did not represent a strategic shift and will not have a major effect on its consolidated results of operations, financial position or cash flows. Accordingly, the Company has not presented the sale as a discontinued operation in the condensed consolidated financial statements. Efflux On July 12, 2017 (the Efflux Closing Date), the Company completed the acquisition of Efflux for $8.6 million . Efflux's technology detects, analyzes and correlates threat activity within enterprise networks. The Efflux technology and engineering talent have been integrated into Arbor Networks in order to support the ongoing enhancement of Arbor security solutions for advanced threat detection. Goodwill was recognized for the excess purchase price over the fair value of the net assets acquired. Goodwill of $6.1 million from the acquisition was included within the Security reporting unit. Goodwill and intangible assets recorded as part of the acquisition are not deductible for tax purposes. |

Goodwill and Intangible Assets Disclosure [Abstract] | |
GOODWILL AND INTANGIBLE ASSETS | GOODWILL AND INTANGIBLE ASSETS Goodwill The Company has two reporting units: (1) Service Assurance and (2) Security. The Company assesses goodwill for impairment at the reporting unit level at least annually, or on an interim basis if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. The Company completed its annual impairment test on January 31, 2018. The Company performed an interim quantitative test as of September 30, 2018 related to the HNT tools business divestiture. The estimated fair value of both reporting units significantly exceeded their carrying value. At September 30, 2018 , goodwill attributable to our Service Assurance and Security reporting units was $1.2 billion and $555.4 million , respectively. At March 31, 2018 , goodwill attributable to our Service Assurance and Security reporting units was $1.2 billion and $555.9 million , respectively. The change in the carrying amount of goodwill for the six months ended September 30, 2018 is due to the impact of the divestiture of the HNT tools business and foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar. The changes in the carrying amount of goodwill for the six months ended September 30, 2018 are as follows (in thousands): Balance at March 31, 2018 $ 1,712,764 Divestiture of the HNT tools business (4,414 ) Foreign currency translation impact 4,612 Balance at September 30, 2018 $ 1,712,962 Intangible Assets The net carrying amounts of intangible assets were $720.9 million and $ 831.4 million at September 30, 2018 and March 31, 2018 , respectively. Intangible assets acquired in a business combination are recorded under the acquisition method of accounting at their estimated fair values at the date of acquisition. The Company amortizes intangible assets over their estimated useful lives, except for the acquired trade name which resulted from the Network General Central Corporation (Network General) acquisition, which has an indefinite life and thus is not amortized. The carrying value of the indefinite-lived trade name is evaluated for potential impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. During the three months ended June 30, 2018, the Company performed a quantitative analysis on certain intangible assets related to the HNT tools business, which has since been divested. The fair value for the intangible assets related to the HNT tools business was calculated considering a range of potential transaction prices which the Company considers to be a Level 3 measurement. The fair value of these intangible assets was determined to be less than the carrying value, and as a result, the Company recognized an impairment charge of $35.9 million in the six months ended September 30, 2018 . The impairment charge was recorded within a separate operating expense line item in the Company's consolidated statements of operations during the six months ended September 30, 2018 . The Company performed an interim qualitative test as of September 30, 2018 on the non-amortizing trademark as a result of the HNT tools business divestiture. No indicators of impairment were noted at that time. In September 2018, the Company completed the divestiture of its HNT tools business. As a result, the net carrying value of the Company's intangible assets was reduced by $10.2 million . Intangible assets include the indefinite-lived trade name with a carrying value of $18.6 million and the following amortizable intangible assets at September 30, 2018 (in thousands): Cost Accumulated Amortization Net Developed technology $ 243,093 $ (153,856 ) $ 89,237 Customer relationships 775,868 (188,347 ) 587,521 Distributor relationships and technology licenses 6,931 (4,571 ) 2,360 Definite-lived trademark and trade name 39,430 (18,016 ) 21,414 Core technology 7,252 (6,761 ) 491 Net beneficial leases 336 (336 ) — Non-compete agreements 301 (301 ) — Leasehold interest 500 (500 ) — Backlog 16,486 (16,486 ) — Capitalized software 3,183 (2,152 ) 1,031 Other 1,208 (913 ) 295 $ 1,094,588 $ (392,239 ) $ 702,349 Intangible assets include the indefinite-lived trade name with a carrying value of $18.6 million and the following amortizable intangible assets at March 31, 2018 (in thousands): Cost Accumulated Amortization Net Developed technology $ 259,758 $ (148,937 ) $ 110,821 Customer relationships 845,490 (176,425 ) 669,065 Distributor relationships and technology licenses 9,019 (5,389 ) 3,630 Definite-lived trademark and trade name 44,387 (18,138 ) 26,249 Core technology 7,345 (6,712 ) 633 Net beneficial leases 336 (336 ) — Non-compete agreements 317 (317 ) — Leasehold interest 2,600 (2,130 ) 470 Backlog 18,544 (18,544 ) — Capitalized software 3,183 (1,621 ) 1,562 Other 1,247 (903 ) 344 $ 1,192,226 $ (379,452 ) $ 812,774 Amortization included as product revenue consists of amortization of backlog.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES | DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES NetScout operates internationally and, in the normal course of business, is exposed to fluctuations in foreign currency exchange rates. The exposures result from costs that are denominated in currencies other than the U.S. Dollar, primarily the Euro, British Pound, Canadian Dollar, and Indian Rupee. The Company manages its foreign cash flow risk by hedging forecasted cash flows for operating expenses denominated in foreign currencies for up to twelve months, within specified guidelines through the use of forward contracts. The Company enters into foreign currency exchange contracts to hedge cash flow exposures from costs that are denominated in currencies other than the U.S. Dollar. These hedges are designated as cash flow hedges at inception. All of the Company's derivative instruments are utilized for risk management purposes, and the Company does not use derivatives for speculative trading purposes. These contracts will mature over the next twelve months and are expected to impact earnings on or before maturity. The notional amounts and fair values of derivative instruments in the consolidated balance sheets at September 30, 2018 and March 31, 2018 were as follows (in thousands): Notional Amounts (a) Prepaid Expenses and Other Current Assets Accrued Other September 30, March 31, September 30, March 31, September 30, March 31, Derivatives Designated as Hedging Instruments: Forward contracts $ 10,001 $ 11,225 $ 16 $ 122 $ 220 $ 40 (a) Notional amounts represent the gross contract/notional amount of the derivatives outstanding.

Debt Disclosure [Abstract] | |
LONG-TERM DEBT | LONG-TERM DEBT On January 16, 2018, the Company amended and expanded its existing credit agreement (Amended Credit Agreement) with a syndicate of lenders by and among: the Company; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; J.P. Morgan Securities LLC, KeyBanc Capital Markets, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets and Wells Fargo Securities, LLC, as joint lead arrangers and joint bookrunners; Fifth Third Bank, Santander Bank, N.A., SunTrust Bank, N.A. and U.S. Bank National Association, as co-documentation agents; and the lenders party thereto. The Amended Credit Agreement provides for a five -year, $1.0 billion senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million . The Company may elect to use the new credit facility for general corporate purposes or to finance the repurchase of up to 25 million shares of the Company's common stock under the Company's common stock repurchase plan. The commitments under the Amended Credit Agreement will expire on January 16, 2023, and any outstanding loans will be due on that date. On February 1, 2018, the Company also announced that it entered into agreements with JPMorgan Chase Bank, National Association and Bank of America, N.A. (the Dealers) to repurchase an aggregate of $300 million of the Company's common stock via accelerated stock repurchase transactions (the ASR) under the Company's previously disclosed share repurchase program. On February 1, 2018, the Company borrowed an additional $300 million aggregate principal amount under its Amended Credit Agreement in order to finance the payment of the ASR to each of the Dealers. The Company completed the ASR in August 2018. At September 30, 2018 , $600 million was outstanding under the Amended Credit Agreement. At the Company's election, revolving loans under the Amended Credit Agreement bear interest at either (a) an Alternate Base Rate per annum equal to the greatest of (1) JPMorgan's prime rate, (2) 0.50% in excess of the New York Federal Reserve Bank (NYFRB) rate, or (3) an adjusted one month LIBOR rate plus 1% ; or (b) such adjusted LIBOR rate (for the interest period selected by the Company), in each case plus an applicable margin. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2018, until the Company has delivered financial statements for the quarter ended September 30, 2018 , the applicable margin will be 1.75% per annum for LIBOR loans and 0.75% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on the Company's leverage ratio, ranging from 1.00% per annum for Base Rate loans and 2.00% per annum for LIBOR loans if the Company's consolidated leverage ratio is greater than 3.50 to 1.00, down to 0.00% per annum for Alternate Base Rate loans and 1.00% per annum for LIBOR loans if the Company's consolidated leverage ratio is equal to or less than 1.50 to 1.00. The Company's consolidated leverage ratio is the ratio of its total funded debt compared to its consolidated adjusted EBITDA. Consolidated adjusted EBITDA includes certain adjustments, including, without limitation, adjustments relating to extraordinary, unusual or non-recurring charges, certain restructuring charges, non-cash charges, certain transaction costs and expenses and certain pro forma adjustments in connection with material acquisitions and dispositions, all as set forth in detail in the definition of consolidated adjusted EBITDA in the Amended Credit Agreement. Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2018 until the Company has delivered financial statements for the quarter ended September 30, 2018 , the commitment fee was 0.30% per annum, and thereafter the commitment fee will vary depending on the Company's consolidated leverage ratio, ranging from 0.30% per annum if the Company's consolidated leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if the Company's consolidated leverage ratio is equal to or less than 1.50 to 1.00. Letter of credit participation fees are payable to each lender on the amount of such lender’s letter of credit exposure, during the period from the closing date of the Amended Credit Agreement to but excluding the date which is the later of (i) the date on which such lender’s commitment terminates or (ii) the date on which such lender ceases to have any letter of credit exposure, at a rate per annum equal to the applicable margin for LIBOR loans. Additionally, the Company will pay a fronting fee to each issuing bank in amounts to be agreed to between the Company and the applicable issuing bank. Interest on Alternate Base Rate loans is payable at the end of each calendar quarter. Interest on LIBOR loans is payable at the end of each interest rate period or at the end of each three-month interval within an interest rate period if the period is longer than three months. The Company may also prepay loans under the Amended Credit Agreement at any time, without penalty, subject to certain notice requirements. Debt is recorded at the amount drawn on the revolving credit facility plus interest based on floating rates reflective of changes in the market which approximates fair value. The loans and other obligations under the credit facility are (a) guaranteed by each of the Company's wholly owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of the Company and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by the Company and the subsidiary guarantors (which pledge, in the case of any foreign subsidiary, is limited to 65% of the voting stock), subject to certain customary exceptions and limitations. The Amended Credit Agreement generally prohibits any other liens on the assets of the Company and its restricted subsidiaries, subject to certain exceptions as described in the Amended Credit Agreement. The Amended Credit Agreement contains certain covenants applicable to the Company and its restricted subsidiaries, including, without limitation, limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, including sale-leaseback transactions, speculative hedge agreements, payment of junior financing, changes in business and other limitations customary in senior secured credit facilities. In addition, the Company is required to maintain certain consolidated leverage and interest coverage ratios. These covenants and limitations are more fully described in the Amended Credit Agreement. At September 30, 2018 , the Company was in compliance with all of these covenants. The Amended Credit Agreement provides that events of default will exist in certain circumstances, including failure to make payment of principal or interest on the loans when required, failure to perform certain obligations under the Amended Credit Agreement and related documents, defaults under certain other indebtedness, certain insolvency events, certain events arising under ERISA, a change of control and certain other events. Upon an event of default, the administrative agent with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments may terminate the commitments and accelerate the maturity of the loans and enforce certain other remedies under the Amended Credit Agreement and the other loan documents. In connection with the Company's Amended Credit Agreement described above, the Company terminated its previous term loan dated as of July 14, 2015, by and among the Company; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; J.P. Morgan Securities LLC, KeyBanc Capital Markets, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets and Wells Fargo Securities, LLC, as joint lead arrangers and joint bookrunners; Santander Bank, N.A., SunTrust Bank, N.A. and U.S. Bank National Association, as co-documentation agents; and the lenders party thereto. The Company has capitalized debt issuance costs totaling $12.2 million at September 30, 2018 , which are being amortized over the life of the revolving credit facility. The unamortized balance was $7.5 million as of September 30, 2018 . The balance of $1.8 million was included as prepaid expenses and other current assets and a balance of $5.7 million was included as other assets in the Company's consolidated balance sheet. |

Restructuring and Related Activities [Abstract] | |
RESTRUCTURING CHARGES | RESTRUCTURING CHARGES During the fourth quarter of fiscal year ended March 31, 2017, the Company restructured certain departments to better align functions subsequent to the acquisition of Danaher Corporation's Communications Business (the Comms Transaction) in July 2015, resulting in the termination of forty-one employees. As a result of the workforce reduction, during the fiscal year ended March 31, 2017, the Company recorded a restructuring charge totaling $1.9 million related to one-time termination benefits and $0.4 million in facility-related charges. The Company recorded an additional charge for one-time termination benefits of $0.7 million during the six months ended September 30, 2017. The one-time termination benefits and facilities-related costs related to this plan were paid in full during the fiscal year ended March 31, 2018. During the third quarter of fiscal year ended March 31, 2018, the Company restructured certain departments to better align functions resulting in the termination of sixty-one employees. As a result of the workforce reduction, during the twelve months ended March 31, 2018, the Company recorded a restructuring charge totaling $5.1 million related to one-time termination benefits for the employees that were notified during the period. During the six months ended September 30, 2018 , the Company recorded an additional charge of $1.7 million for one-time termination benefits and facilities-related costs. Additional immaterial one-time termination benefit charges are expected to be recorded in the next three months. The one-time termination benefits will be paid in full during the fiscal year ending March 31, 2019. During the second quarter of fiscal year ending March 31, 2019, the Company implemented a voluntary separation program (VSP) for employees who met certain age and service requirements to reduce overall headcount. As a result of the related workforce reduction, during the six months ended September 30, 2018, the Company recorded a restructuring charge totaling $2.3 million related to one-time termination benefits for twenty-three employees who voluntarily terminated their employment with the Company during the period. Additional one-time termination benefit charges of approximately $16.1 million in the aggregate for up to approximately one hundred forty-one employees are anticipated to be recorded in the next six months. The one-time termination benefits are expected to be paid in full by the end of the first quarter of the fiscal year ending March 31, 2020. The following table provides a summary of the activity related to the restructuring plans and the related restructuring liability (in thousands): Q3 FY 2018 Plan VSP Employee-Related Facility-Related Employee-Related Total Balance at March 31, 2018 $ 3,696 $ — $ — $ 3,696 Restructuring charges to operations 1,017 643 2,284 3,944 Cash payments (4,241 ) (458 ) (1,971 ) (6,670 ) Other adjustments (462 ) (185 ) — (647 ) Balance at September 30, 2018 $ 10 $ — $ 313 $ 323 The accrual for employee-related severance is included as accrued compensation in the Company's consolidated balance sheets at September 30, 2018 and March 31, 2018 as the balance is expected to be paid in full within the next twelve months. |

Commitments and Contingencies Disclosure [Abstract] | |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES Acquisition related – The Company has a contingent liability related to the acquisition of Simena in November 2011 for future consideration to be paid to the seller which had an initial fair value of $8.0 million at the time of acquisition. At September 30, 2018 and March 31, 2018, the present value of the future consideration was $5.0 million and $4.9 million , respectively. The Company had a contingent liability at March 31, 2018 for $523 thousand related to the acquisition of Efflux in July 2017. The $523 thousand was released from escrow to the sellers in July 2018. Legal – From time to time, NetScout is subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows. As previously disclosed, in March 2016, Packet Intelligence LLC (Packet Intelligence or Plaintiff) filed a Complaint against NetScout and two subsidiary entities in the United States District Court for the Eastern District of Texas asserting infringement of five United States patents. Plaintiff’s Complaint alleged that legacy Tektronix GeoProbe products, including the G10 and GeoBlade products, infringed these patents. NetScout filed an Answer denying Plaintiff’s allegations and asserting that Plaintiff’s patents were, among other things, invalid, not infringed, and unenforceable due to inequitable conduct. In October 2017, a jury trial was held to address the parties’ claims and counterclaims regarding infringement of three patents by the G10 and GeoBlade products, invalidity of these patents, and damages. On October 13, 2017, the jury rendered a verdict finding in favor of the Plaintiff and that Plaintiff was entitled to $3,500,000 for pre-suit damages and $2,250,000 for post-suit damages. The jury indicated that the awarded damages amounts were intended to reflect a running royalty. The Court also conducted a bench trial on whether these patents were unenforceable due to, among other things, inequitable conduct. In September 2018, the Court entered judgment and "enhanced" the jury verdict in the amount of $2.8 million as a result of a jury finding. The judgment also awards pre- and post judgement interest, and a running royalty on the G10 and Geoblade products until the expiration of the patents at issue, the last date being June 2022. The parties are filing post-judgment motions including NetScout's motions for judgment as a matter of law seeking to both overturn the verdict and to reduce damages. NetScout has also opposed plaintiff's motion for attorney's fees. NetScout has concluded that the risk of loss from this matter is currently neither remote nor probable, and therefore, under GAAP definitions, the risk of loss is termed "reasonably possible". Therefore, accounting rules require NetScout to provide an estimate for the range of potential liability. NetScout currently estimates that the estimated range of liability is between $0 and the aggregate amount awarded by the jury, plus potential additional pre- and post-judgment interest amounts and costs. NetScout intends to continue to vigorously dispute Packet Intelligence’s claims including through appeal, if necessary. |

PENSION BENEFIT PLANS | PENSION BENEFIT PLANS Certain of the Company's non-U.S. employees participate in noncontributory defined benefit pension plans. None of the Company's employees in the U.S. participate in any noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plan's funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors. The following sets forth the components of the Company's net periodic pension cost of the noncontributory defined benefit pension plans for the three and six months ended September 30, 2018 and 2017 (in thousands): Three Months Ended Six Months Ended September 30, September 30, 2018 2017 2018 2017 Service cost $ 63 $ 70 $ 126 $ 141 Interest cost 123 136 244 273 Net periodic pension cost $ 186 $ 206 $ 370 $ 414 Expected Contributions During the six months ended September 30, 2018 , the Company made contributions of $0.1 million to its defined benefit pension plans. During the fiscal year ending March 31, 2019 , the Company's cash contribution requirements for its defined benefit pension plans are expected to be less than $1.0 million . As a majority of the participants within the Company's plans are all active employees, the benefit payments are not expected to be material in the foreseeable future. |

Equity [Abstract] | |
TREASURY STOCK | TREASURY STOCK On May 19, 2015, the Company's board of directors approved a share repurchase program, conditional upon the completion of the Comms Transaction. This program enabled the Company to repurchase up to 20 million shares of its common stock. This plan became effective on July 14, 2015 upon the completion of the Comms Transaction. The Company was not obligated to acquire any specific amount of common stock within any particular timeframe under this program. The Company repurchased 2,780,433 shares for $100.0 million under this program during the six months ended September 30, 2017 . Through March 31, 2018 , the Company had repurchased 20,000,000 shares totaling $607.6 million in the open market under this stock repurchase plan. At March 31, 2018 , there were no shares of common stock that remained available to be purchased under the plan. On October 24, 2017, the Company’s Board of Directors approved a new share repurchase program that enables the Company to repurchase up to twenty-five million shares of its common stock. This new program became effective when the Company’s previously disclosed twenty million share repurchase program was completed. The Company is not obligated to acquire any specific amount of common stock within any particular timeframe as a result of this new share repurchase program. On February 1, 2018, the Company entered into ASR agreements with two third-party financial institutions (the Dealers) to repurchase an aggregate of $300 million of the Company's common stock via accelerated stock repurchase transactions under the Company’s twenty million share repurchase program (until such program was completed) and the twenty-five million share repurchase program. The Company borrowed $300 million against its Amended Credit Facility to finance the payment of the initial purchase price to each of the Dealers. Under the terms of the ASR, the Company made a $150 million payment to each of the Dealers on February 2, 2018, and received an initial delivery of 3,693,931 shares from each of the Dealers, or 7,387,862 shares in the aggregate, which was approximately 70 percent of the total number of shares of the Company's common stock expected to be repurchased under the ASR. As part of this purchase, 970,650 shares for $27.6 million were deducted under the twenty million share repurchase program and 6,417,212 shares for $182.4 million were deducted from the twenty-five million share repurchase program during the fiscal year ended March 31, 2018. Final settlement of the ASR agreements were completed in August 2018. As a result, the Company received an additional 3,679,947 shares of its common stock for $96.8 million , which reduced the number of shares available to be purchased from the twenty-five million share repurchase program during the six months ended September 30, 2018. In total, 11,067,809 shares of the Company's common stock were repurchased under the ASR at an average cost per share of $27.11 . At September 30, 2018 , 14,902,841 shares of common stock remained available to be purchased under the current program. In connection with the delivery of shares of the Company's common stock upon vesting of restricted stock units, the Company withheld 371,726 shares at a cost of $9.9 million related to minimum statutory tax withholding requirements on these restricted stock units during the six months ended September 30, 2018 . These withholding transactions do not fall under the repurchase program described above, and therefore do not reduce the amount that is available for repurchase under that program. |

NET LOSS PER SHARE | NET LOSS PER SHARE Calculations of the basic and diluted net loss per share and potential common shares are as follows (in thousands, except for per share data): Three Months Ended Six Months Ended September 30, September 30, 2018 2017 2018 2017 Numerator: Net loss $ (26,428 ) $ (2,468 ) $ (88,932 ) $ (26,690 ) Denominator: Denominator for basic net loss per share - weighted average common shares outstanding 78,631 88,589 79,490 89,878 Dilutive common equivalent shares: Weighted average restricted stock units — — — — Denominator for diluted net loss per share - weighted average shares outstanding 78,631 88,589 79,490 89,878 Net loss per share: Basic net loss per share $ (0.34 ) $ (0.03 ) $ (1.12 ) $ (0.30 ) Diluted net loss per share $ (0.34 ) $ (0.03 ) $ (1.12 ) $ (0.30 ) The following table sets forth restricted stock units excluded from the calculation of diluted net loss per share, since their inclusion would be anti-dilutive (in thousands): Three Months Ended Six Months Ended September 30, September 30, 2018 2017 2018 2017 Restricted stock units 731 936 895 1,102 Basic net loss per share is calculated by dividing net loss by the weighted average number of shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted net loss per share is calculated by dividing net loss by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, restricted shares and restricted stock units using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of stock options and unrecognized compensation expense as additional proceeds. As we incurred a net loss in the three and six months ended September 30, 2018 and 2017, all outstanding restricted stock units have an anti-dilutive effect and are therefore excluded from the computation of diluted weighted average shares outstanding. |

Income Tax Disclosure [Abstract] | |
INCOME TAXES | INCOME TAXES The Company's effective income tax rates were 9.1% and 45.9% for the three months ended September 30, 2018 and 2017 , respectively. Generally, the effective tax rate differs from the statutory tax rate due to the impact of the research and development credit, the impact of state taxes and income generated in jurisdictions that have a different tax rate than the U.S. statutory rate. The effective tax rate for the three months ended September 30, 2018 is lower than the effective rate for the three months ended September 30, 2017 , primarily due to the enactment of the Tax Legislation and a significant increase in loss before income tax benefit. The Company's effective income tax rates were 19.7% and 35.3% for the six months ended September 30, 2018 and 2017 , respectively. The effective tax rate for the six months ended September 30, 2018 is lower than the effective rate for the six months ended September 30, 2017 , primarily due to the enactment of the Tax Legislation and a significant increase in loss before income tax benefit. On December 22, 2017, the Tax Legislation was signed into law. The Tax Legislation significantly revises the U.S. tax code by, among other things, lowering the corporate tax rate from 35% to 21% ; imposing a minimum tax on certain foreign earnings; limiting the deductibility of interest expense; implementing a territorial tax system and repealing the domestic production activities deduction. In December 2017, the SEC issued Staff Accounting Bulletin No. 118 (SAB 118), which addresses situations where the accounting is incomplete for the income tax effects of the Tax Legislation. SAB 118 directs taxpayers to consider the impact of the Tax Legislation as “provisional” when the Company does not have the necessary information available, prepared or analyzed (including computations) to finalize the accounting for the change in tax law. Companies are provided a measurement period of up to one year to obtain, prepare, and analyze information necessary to finalize the accounting for provisional amounts or amounts that could not be estimated as of December 31, 2017. The Company continues to assess the impact of the Tax Legislation on its consolidated financial statements. During the three months ended September 30, 2018 , the Company decreased its provisional tax expense estimate related to the transition tax associated with the deemed repatriation of foreign earnings by $1.3 million after continued assessment of guidance and recently issued regulations. The Company is still in the process of analyzing the impact of the Tax Legislation, including any potential impact on its indefinite reinvestment assertion. The Company is subject to the tax on the Global Intangible Low-Taxed Income (GILTI) but has not completed its analysis of the applicability of the tax. As of September 30, 2018 , the Company is still evaluating the effects of the GILTI provisions as guidance and interpretations continue to develop. Therefore, the Company will not make a policy election on how to account for GILTI (as part of deferred taxes or as a period expense) until management has received and evaluated the necessary information. However, FASB Accounting Standards Codification 740, Income Taxes (ASC 740) requires that the Company reflects the impact of the GILTI provisions as a period expense until the accounting policy is finalized. Accordingly, the Company has included an estimate of GILTI in its estimated annual effective tax rate and will update the impact and accounting policy once the analysis related to the GILTI provisions is complete. |

SEGMENT AND GEOGRAPHIC INFORMATION | SEGMENT AND GEOGRAPHIC INFORMATION The Company reports revenues and income under one reportable segment. The Company manages its business in the following geographic areas: United States, Europe, Asia and the rest of the world. In accordance with United States export control regulations, the Company does not sell or do business with countries subject to economic sanctions and export controls. Total revenue by geography is as follows (in thousands): Three Months Ended Six Months Ended September 30, September 30, 2018 2017 2018 2017 United States $ 136,752 $ 153,632 $ 263,998 $ 292,250 Europe 33,450 43,102 64,471 78,550 Asia 18,198 25,201 36,098 44,728 Rest of the world 35,397 34,928 64,341 67,091 $ 223,797 $ 256,863 $ 428,908 $ 482,619 The United States revenue includes sales to resellers in the United States. These resellers fulfill customer orders and may subsequently ship the Company’s products to international locations. The Company reports these shipments as United States revenue because the Company ships the products to a United States location. Further, the Company determines the geography of its sales after considering where the contract originated. A majority of revenue attributable to locations outside of the United States is a result of export sales. Substantially all of the Company's identifiable assets are located in the United States. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | The accompanying unaudited interim consolidated financial statements have been prepared by NetScout Systems, Inc. (NetScout or the Company). Certain information and footnote disclosures normally included in financial statements prepared under United States generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the Company's financial position, results of operations and cash flows. The year-end consolidated balance sheet data was derived from the Company's audited financial statements, but does not include all disclosures required by GAAP. The results reported in these unaudited interim consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. All significant intercompany accounts and transactions are eliminated in consolidation. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 filed with the Securities and Exchange Commission on May 21, 2018. Certain amounts for the three and six months ended September 30, 2017 have been reclassified to conform to the current period presentation. These reclassifications had no effect on the reported results of operations. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15). This ASU clarifies the accounting treatment for implementation costs for cloud computing arrangements (hosting arrangements) that is a service contract. This guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. The Company adopted ASU 2018-15 effective July 1, 2018. The adoption has had an immaterial impact to the consolidated financial statements for the three months ended September 30, 2018 . In August 2018, the FASB issued ASU 2018-14, Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans.

Early adoption is permitted. The Company is currently assessing the effect that ASU 2018-13 will have on its financial position, results of operations, and disclosures. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income (ASU 2018-02). ASU 2018-02 amends ASC 220, Income Statement - Reporting Comprehensive Income, to allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (Tax Legislation). In addition, under the ASU 2018-02, the Company may be required to provide certain disclosures regarding stranded tax effects. ASU 2018-02 is effective for years beginning after December 15, 2018, and interim periods within those fiscal years. ASU 2018-02 is effective for NetScout beginning April 1, 2019. Early adoption is permitted. The Company does not believe the adoption of ASU 2018-02 will have a material impact on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). ASU 2017-12 provides guidance to better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This standard is effective for financial statements issued for fiscal years beginning after December 15, 2018, with early adoption permitted. ASU 2017-12 is effective for the Company beginning April 1, 2019. The Company is currently assessing the potential impact of the adoption of ASU 2017-12 on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Section A - Leases: Amendments to the FASB Accounting Standards Codification (ASU 2016-02), its new standard on accounting for leases. This update requires the recognition of leased assets and lease obligations by lessees for those leases currently classified as operating leases under existing lease guidance. Short term leases with a term of 12 months or less are not required to be recognized. The update also requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements and ASU 2018-10, Codification Improvements to Topic 842, Leases. ASU 2016-02 and the subsequent modifications are identified as ASC 842. ASC 842 will be effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal years. ASC 842 requires a modified retrospective transition method with the option to elect a package of practical expedients. Early adoption is permitted. The Company expects the adoption to increase the assets and liabilities recorded on its consolidated balance sheet and increase the level of disclosures related to leases. In addition, the Company is in the process of identifying appropriate changes to its accounting policies, information technology systems, business processes, and related internal controls to support recognition and disclosure requirements under ASC 842. The Company expects to design any necessary changes to its business processes, controls and systems in the near future and implement the changes over the remainder of fiscal year 2019. ASC 842 is effective for the Company beginning April 1, 2019. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (Topic 606). Topic 606 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The Company adopted Topic 606 as of April 1, 2018 using the modified retrospective transition method. Please refer to Note 2, "Revenue Recognition" for further details. |
