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 and stockholders' equity, results of operations and cash flows. The year-end consolidated balance sheet data and statement of stockholders' equity were derived from the Company's audited financial statements, but do 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, 2022 filed with the Securities and Exchange Commission on May 19, 2022. Macroeconomic Conditions and COVID-19 Impact The Company continues to closely monitor the current global and macroeconomic conditions, including the impact of the corona-virus (COVID-19) pandemic, the war in Ukraine, global geopolitical tension, stock market volatility, exchange rate fluctuations, rising inflation and interest rates, and the risk of a recession, on all aspects of its business, including the manner and extent to which they have impacted and could continue to impact its customers, employees, supply chain, and distribution network. The impacts of these global and macroeconomic trends and the COVID-19 pandemic remain uncertain. It is possible that the measures taken by the governments of countries affected and the resulting economic impact may materially and adversely affect the Company's future results of operations, cash flows and financial position as well as its customers. The Company has the responsibility to evaluate whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date that the financial statements are issued. The Company has taken and continues to take precautionary actions to manage costs and spending across the organization. This includes managing discretionary spending and hiring activities. In addition, based on covenant levels, the Company had, as of September 30, 2022, an incremental $600 million available under its revolving credit facility. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (the CARES Act) was enacted. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The Company had elected to defer the employer-paid portion of social security taxes. As of September 30, 2022, the Company had deferred $4.5 million of employer payroll taxes, which is required to be deposited by December 2022. The balance of $4.5 million was included as accrued other in the Company's consolidated balance sheet at September 30, 2022. The Company expects net cash provided by operations combined with cash, cash equivalents, and marketable securities and borrowing availability under the revolving credit facility to provide sufficient liquidity to fund current obligations, capital spending, debt service requirements and working capital requirements over at least the next twelve months. Recent Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires companies to recognize and measure contract assets and contract liabilities acquired in a business combination as if the acquiring company originated the related revenue contracts. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. ASU 2021-08 is effective for the Company beginning April 1, 2023. Amendments within the standard are required to be applied on a prospective basis from the date of adoption. The adoption is not expected to have a material impact on the Company's financial position, results of operations, and disclosures. We will apply the provisions of ASU 2021-08 after adoption to future acquisitions, if any. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments provide optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE 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 cybersecurity solutions for service provider and enterprise customers, which include hardware, software, and service offerings. The Company's product sales consist of software only offerings and offerings which include hardware appliances with embedded software that are essential to providing customers the intended functionality of the solutions. 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 the amount the Company deems probable of collection. 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 typically recognized upon fulfillment, 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. 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 the Company's 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 primarily on the performance obligation'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 performance obligations 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. SSP has primarily been established for product performance obligations as the average or median selling price the performance obligation was recently sold for, whether sold alone or sold as part of a bundle transaction. The Company reviews sales of the product performance obligations on a quarterly basis and updates, when appropriate, its SSP for such performance obligations 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, when control of the product transfers to the reseller or distributor. The Company records consideration given to a customer as a reduction of revenue to the extent they have recorded revenue from the customer. 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. During the six months ended September 30, 2022, the Company recognized revenue of $203.7 million related to the Company's deferred revenue balance reported at March 31, 2022. 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, 2022. At September 30, 2022, the Company had total deferred revenue of $410.8 million, which represents the aggregate total contract price allocated to undelivered performance obligations. The Company expects to recognize $287.3 million, or 70%, of this revenue during the next 12 months, and expects to recognize the remaining $123.5 million, or 30%, 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, the Company does not believe its right to payment is unconditional, therefore 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 because control of the underlying deliverable has not transferred. The aggregate amount of unrecognized accounts receivable and deferred revenue was $6.8 million and $9.4 million at September 30, 2022 and March 31, 2022, 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, th e specific timing of customer renewals, and foreign currency fluctuations. The Company did not have material significant financing components, or variable consideration or performance obligations satisfied in a prior period recognized during the six months ended September 30, 2022. Contract Balances The Company may receive payments from customers based on billing schedules as established by the Company's contracts. Contract assets relate to performance obligations where control has transferred to the customer in advance of scheduled billings. The Company records 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. Deferred revenue relates to scenarios where billings with an unconditional right to payment occur before all performance obligations are delivered or payments are received in advance of performance under the contract. Costs to Obtain Contracts The Company has determined that the only significant incremental costs incurred to obtain contracts with customers within the scope of Topic 606 are sales commissions paid to its employees. 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 expenses costs as incurred for sales commissions when the amortization period would have been one year or less. At September 30, 2022, the consolidated balance sheet included $9.4 million in assets related to sales commissions to be expensed in future periods. A balance of $4.9 million was included in prepaid expenses and other current assets, and a balance of $4.5 million was included in other assets in the Company's consolidated balance sheet at September 30, 2022. At March 31, 2022, the consolidated balance sheet included $8.8 million in assets related to sales commissions to be expensed in future periods. A balance of $4.6 million was included in prepaid expenses and other current assets, and a balance of $4.2 million was included in other assets in the Company's consolidated balance sheet at March 31, 2022. During the three and six months ended September 30, 2022 and 2021, respectively, the Company recognized $1.7 million, $1.5 million, $3.5 million and $3.1 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. Allowance for Credit Losses The Company continually monitors collections from its customers. The Company evaluates the collectability of its accounts receivable and determines the appropriate allowance for credit losses based on a combination of factors, including but not limited to, analysis of the aging schedules, past due balances, historical collection experience and prevailing economic conditions. The following table summarizes the activity in the allowance for credit losses (in thousands): Balance at March 31, 2022 $ 1,649 Provision for allowance for credit losses 734 Recoveries and other adjustments 259 Write off charged against the allowance for credit losses (739) Balance at September 30, 2022 $ 1,903

Share-Based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION On September 12, 2019, the Company's stockholders approved the 2019 Equity Incentive Plan (2019 Plan), which replaced the Company's 2007 Equity Incentive Plan, as amended (Amended 2007 Plan). The 2019 Plan permits the granting of incentive and nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other stock awards, collectively referred to as "share-based awards." On September 10, 2020, the Company's stockholders approved an amendment and restatement of the 2019 Plan (2019 Amended Plan) to increase the number of shares reserved for issuance by 4,700,000 shares, established a one-year minimum vesting requirement for awards granted on or after September 10, 2020, and changed the factor used to calculate the increase or reduction in the number of shares available for issuance under the 2019 Amended Plan. On August 24, 2022, the Company's stockholders approved an amendment to the 2019 Amended Plan (2019 Second Amended Plan). This amendment increased the number of shares reserved for issuance by 7,000,000 shares and changed the factor used to calculate the increase or reduction in the number of shares available for issuance under the 2019 Second Amended Plan. At August 24, 2022, there was a total of 8,764,811 shares reserved for issuance under the 2019 Second Amended Plan, which consisted of 7,000,000 new shares plus 1,764,811 shares that remained available for grant under the 2019 Amended Plan as of August 24, 2022, the effective date of the 2019 Second Amended Plan. At September 30, 2022, an aggregate of 6,774,194 shares of unvested equity awards were outstanding under the 2019 Second Amended Plan. Periodically, the Company grants share-based awards to employees, officers, and directors of the Company and its subsidiaries. During the fiscal year ended March 31, 2022, the Company granted performance-based restricted stock units to certain executive officers that vest based upon the Company's total shareholder return as compared to the Russell 2000 Index over a three-year period ending in June 2024. The performance-based restricted stock units were valued using the Monte Carlo Simulation model. The measurement and recognition of compensation expense is based on estimated fair values for all share-based payment awards made to its employees and directors. Share-based award grants are generally measured at fair value on the date of grant based on the number of shares granted and the quoted price of the Company's common stock. Such value is recognized as a cost of revenue or an operating expense over the corresponding vesting period. The following is a summary of share-based compensation expense including restricted stock units and performance-based restricted stock units granted pursuant to the Company's Amended 2007 Plan, the 2019 Plan, the 2019 Amended Plan, and the 2019 Second Amended Plan, and employee stock purchases made under the Company's 2011 Amended and Restated Employee Stock Purchase Plan (ESPP), based on estimated fair values within the applicable cost and expense lines identified below (in thousands): Three Months Ended Six Months Ended September 30, September 30, 2022 2021 2022 2021 Cost of product revenue $ 315 $ 321 $ 607 $ 595 Cost of service revenue 2,080 1,907 3,825 3,520 Research and development 4,580 4,902 9,011 8,993 Sales and marketing 6,043 5,842 11,793 10,656 General and administrative 3,483 3,763 6,846 6,936 $ 16,501 $ 16,735 $ 32,082 $ 30,700 Employee Stock Purchase Plan – The Company maintains the ESPP for all eligible employees as described in the Company's Annual Report on Form 10-K for the year ended March 31, 2022.

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, 2022 and March 31, 2022 (in thousands): Fair Value Measurements at September 30, 2022 Level 1 Level 2 Level 3 Total ASSETS: Cash and cash equivalents $ 274,776 $ 45,549 $ — $ 320,325 U.S. government and municipal obligations 16,143 1,595 — 17,738 Commercial paper — 22,292 — 22,292 Corporate bonds 815 — — 815 Certificate of deposits — 5,961 — 5,961 $ 291,734 $ 75,397 $ — $ 367,131 LIABILITIES: Derivative financial instruments $ — $ (877) $ — $ (877) $ — $ (877) $ — $ (877) Fair Value Measurements at March 31, 2022 Level 1 Level 2 Level 3 Total ASSETS: Cash and cash equivalents $ 617,734 $ 18,427 $ — $ 636,161 U.S. government and municipal obligations 40,863 — — 40,863 Commercial paper — 23,353 — 23,353 Corporate bonds 821 — — 821 Certificate of deposits — 2,000 — 2,000 Derivative financial instruments — 20 — 20 $ 659,418 $ 43,800 $ — $ 703,218 LIABILITIES: Derivative financial instruments $ — $ (78) $ — $ (78) $ — $ (78) $ — $ (78) 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 they are valued using observable inputs other than Level 1 quoted prices that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets in markets that are not active.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS Goodwill The Company has one reporting unit. 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, 2022 using the qualitative assessment as the Company concluded that it was more likely than not that the fair value of the reporting unit exceeded its carrying value. At September 30, 2022 and March 31, 2022, the carrying amount of goodwill was $1.7 billion. The ch ange in the carrying amount of goodwill for the six months ended September 30, 2022 was due to the impact of foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar. The following table summarizes the changes in the carrying amount of goodwill for the six months ended September 30, 2022 as follows (in thousands): Balance at March 31, 2022 $ 1,723,156 Foreign currency translation impact 10,186 Balance at September 30, 2022 $ 1,733,342 Intangible Assets The net carrying amounts of intangible asse ts w ere $393.7 million an d $433.4 million at September 30, 2022 and March 31, 2022, respectively.

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. NetScout also periodically enters into forward contracts to manage exchange rate risks associated with certain third-party transactions and for which the Company does not elect hedge accounting treatment as there is no difference in the timing of gain or loss recognition on the hedging instrument and the hedged item. 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, 2022 and March 31, 2022 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 $ 10,830 $ 5,578 $ — $ 20 $ 877 $ 78 $ — $ 20 $ 877 $ 78 (a) Notional amounts represent the gross contract/notional amount of the derivatives outstanding.

The Second Amended and Restated Credit Agreement provides for a five-year, $800.0 million 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 credit facility for general corporate purposes (including to finance the repurchase of shares of the Company's common stock). The commitments under the Second Amended and Restated Credit Agreement will expire on July 27, 2026, and any outstanding loans will be due on that date. In connection with the Second Amended and Restated Credit Agreement, during the fiscal year ended March 31, 2022, the Company paid off the outstanding balance of $350 million under the Amended Credit Agreement by borrowing the same amount under the Second Amended and Restated Credit Agreement. Additionally, the Company recorded a loss on the extinguishment of debt of $0.6 million, representing the write off of unamortized deferred financing costs, which was included in interest expense in the consolidated statements of operations for the fiscal year ended March 31, 2022. On May 9, 2022, the Company repaid $150.0 million of borrowings under the Second Amended and Restated Credit Agreement. At September 30, 2022, $200 million was outstanding under the Second Amended and Restated Credit Agreement. At the Company's election, revolving loans under the Second Amended and Restated Credit Agreement bear interest at either (a) an Alternate Base Rate per annum equal to the greatest of (1) the Wall Street Journal prime rate; (2) the New York Federal Reserve Bank (NYFRB) rate plus 0.50%, or (3) an adjusted one month LIBO rate plus 1%; or (b) a Term Benchmark Borrowing rate (for the interest period selected by the Company, subject to customary provisions regarding succession from LIBO rate to SOF rate in anticipation of the upcoming discontinuation of the LIBO rate), 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, 2022, until the Company has delivered financial statements for the quarter ended September 30, 2022, the applicable margin will be 1.00% per annum for Term Benchmark Revolving loans and 0% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on the Company's consolidated gross leverage ratio, ranging from 1.00% per annum for Alternate Base Rate loans and 2.00% per annum for Term Benchmark Revolving loans if the Company's consolidated gross leverage ratio is greater than 3.50 to 1.00, down to 0% per annum for Alternate Base Rate loans and 1.00% per annum for Term Benchmark Revolving loans if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00. The Company's consolidated gross leverage ratio is the ratio of its consolidated total debt compared to its consolidated EBITDA as defined in the Second Amended and Restated Credit Agreement (adjusted consolidated EBITDA). Adjusted consolidated 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 Second Amended and Restated 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, 2022, until the Company has delivered financial statements for the quarter ended September 30, 2022, the commitment fee will be 0.15% per annum, and thereafter the commitment fee will vary depending on the Company's consolidated gross leverage ratio, ranging from 0.30% per annum if the Company's consolidated gross leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if the Company's consolidated gross leverage ratio is equal to or less than 1.50 to 1.00. Letter of credit participation fees are payable to each lender providing the letter of credit sub-facility on the amount of such lender's letter of credit exposure, during the period from the closing date of the Second Amended and Restated 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 the applicable rate that would be used to determine the interest rate applicable to Term Benchmark Revolving loans assuming such loans were outstanding during the period. 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 Term Benchmark Revolving 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 Second Amended and Restated Credit Agreement at any time, without penalty, subject to certain notice requirements. 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 Borrower 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 Second Amended and Restated 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 Second Amended and Restated Credit Agreement. The Second Amended and Restated 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. The Second Amended and Restated Credit Agreement requires the Company to maintain a certain consolidated net leverage ratio and removes the previous requirement under the Amended Credit Agreement that the Company maintain a minimum consolidated interest coverage ratio. The Company's consolidated net leverage ratio is the ratio of its Consolidated Total Debt minus the lesser of unrestricted cash and 125% of adjusted consolidated EBITDA compared to its adjusted consolidated EBITDA. The Company’s maximum consolidated net leverage ratio is 4.00 to 1.00. These covenants and limitations are more fully described in the Second Amended and Restated Credit Agreement. As of September 30, 2022, the Company was in compliance with all covenants, including the specified total consolidated net leverage ratio range of 4.00 to 1.00. The Second Amended and Restated 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 Second Amended and Restated Credit Agreement and related documents including a failure to meet the maximum total consolidated net leverage ratio covenant, 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 Second Amended and Restated Credit Agreement and the other loan documents.

LEASES

Leases [Abstract]
LEASES	LEASESThe Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets represent the Company's right to use an underlying asset for the duration of the lease term. Lease liabilities represent the Company's contractual obligation to make lease payments over the lease term. The Company's policy is to combine lease and non-lease components and to not recognize ROU assets and lease liabilities for short-term leases. Leases with an initial term of twelve months or less are classified as short-term leases. ROU assets are recorded and recognized at commencement for the lease liability amount, plus initial direct costs incurred less lease incentives received. Lease liabilities are recorded at the present value of future lease payments over the lease term at commencement. The discount rate used is generally the Company's estimated incremental borrowing rate unless the lessor's implicit rate is readily determinable. Incremental borrowing rates are calculated periodically to estimate the rate the Company would pay to borrow the funds necessary to obtain an asset of similar value over a similar term. Lease expenses relating to operating leases are recognized on a straight-line basis over the lease term. The Company has operating leases for administrative, research and development, sales and marketing and manufacturing facilities and equipment under various non-cancelable lease agreements. The Company's leases have remaining lease terms ranging from 1 year to 9 years. The Company's lease terms may include options to extend or terminate the lease where it is reasonably certain that the Company will exercise those options. The Company considers several economic factors when making this determination, including but not limited to, the significance of leasehold improvements incurred in the office space, the difficulty in replacing the asset, underlying contractual obligations, or specific characteristics unique to a particular lease. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company has an obligation to return certain leased facilities to their original condition at the end of the respective lease term. These obligations were not material to the Company's financial statements for all periods presented. Most of the Company's lease agreements contain variable payments, primarily for common area maintenance (CAM), which are expensed as incurred and not included in the measurement of the ROU assets and lease liabilities. The components of operating lease cost for the three and six months ended September 30, 2022 and 2021, respectively, were as follows (in thousands): Three Months Ended Six Months Ended September 30, September 30, 2022 2021 2022 2021 Lease cost under long-term operating leases $ 3,084 $ 3,197 $ 6,207 $ 6,472 Lease cost under short-term operating leases 1,204 1,183 1,978 1,743 Variable lease cost under short-term and long-term operating leases 873 750 1,856 1,583 Total operating lease cost $ 5,161 $ 5,130 $ 10,041 $ 9,798 The table below presents supplemental cash flow information related to leases during the six months ended September 30, 2022 and 2021 (in thousands): September 30, 2022 September 30, 2021 Right-of-use assets obtained in exchange for new operating lease liabilities $ 493 $ 113 At September 30, 2022 and March 31, 2022, the weighted average remaining lease term in years and weighted average discount rate were as follows: September 30, 2022 March 31, 2022 Weighted average remaining lease term in years - operating leases 6.67 6.98 Weighted average discount rate - operating leases 4.0 % 4.0 % Future minimum payments under non-cancellable leases at September 30, 2022 are as follows (in thousands): Year ending March 31: 2023 (remaining six months) $ 5,761 2024 11,636 2025 10,947 2026 9,586 2027 7,359 Thereafter 22,364 Total lease payments $ 67,653 Less imputed interest (8,351) Present value of lease liabilities $ 59,302

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES 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 adve rsely, 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. In October 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. 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 awarded pre- and post-judgment 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. Following the entry of final judgment, NetScout appealed, and in July 2020, the Court of Appeals for the Federal Circuit (Federal Circuit) issued a decision vacating the $3,500,000 pre-suit damages award, affirming the $2,250,000 post-suit damages award, and remanding to the district court to determine what, if any, enhancement should be awarded. In March 2021, NetScout filed a petition for a writ of certiorari to the United States Supreme Court, which was subsequently denied, challenging, among other issues, the basis for enhanced damages and the patentability of the claimed technology. In addition, on September 8 and 9, 2021, in proceedings initiated by third parties that did not involve NetScout, the Patent Trial and Appeal Board (PTAB) invalidated all the patent claims that were also asserted against NetScout in this case. After the PTAB decisions were issued, NetScout moved, among other things, to dismiss the case and enter judgment in its favor on the grounds that the PTAB decisions invalidating the asserted claims precluded Plaintiff from continuing to assert its patent infringement causes of action and from seeking damages from NetScout. The District Court denied NetScout’s motion with respect to its request to dismiss the case and enter judgment in its favor, but in response to alternative requests for relief requested by NetScout, vacated $1.7 million of the "enhanced" jury verdict amount of $2.8 million and also lowered the ongoing royalty rate on the G10 and GeoBlade products. The District Court entered an amended final judgment awarding Plaintiff $2.25 million in post-suit damages, $1.1 million in enhanced damages, pre- and post-judgment interest, and a running royalty on the G10 and GeoBlade products until the expiration of the patents at issue, the last expiration date being June 2022. On July 20, 2022, NetScout filed a notice of appeal to the Court of Appeals for the Federal Circuit from, among other things, the amended final judgment. In view of the current circumstances, and if the post-suit and enhanced damages award along with the associated interest and royalties survives the recent PTAB invalidation decisions and NetScout's appeal, NetScout has concluded that the risk of loss associated with such damages award remains "probable" in accounting terms, and that the risk of loss associated with pre-suit damages is remote.

Retirement Benefits [Abstract]
PENSION BENEFIT PLANS	PENSION BENEFIT PLANS C ertain 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, 2022 and 2021, respectively, (in thousands): Three Months Ended Six Months Ended September 30, September 30, 2022 2021 2022 2021 Service cost $ 41 $ 44 $ 86 $ 88 Interest cost 84 88 176 180 Net periodic pension cost $ 125 $ 132 $ 262 $ 268 Expected Contributions During the six months ended September 30, 2022, the Company made contributions of $0.2 million to its defined benefit pension plans. During the fiscal year ending March 31, 2023, 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 October 24, 2017, the Company's Board of Directors approved a share repurchase program that enabled the Company to repurchase up to twenty-five million shares of its common stock (2017 Share Repurchase Program). This program became effective when the Company's previously disclosed twenty million share repurchase program was completed. The Company was not obligated to acquire any specific amount of common stock within any particular timeframe as a result of this share repurchase program. Through September 30, 2022, the Company repurchased a total of 22,497,332 shares for $612.6 million in the open market under the 2017 Share Repurchase Program, and at September 30, 2022, 2,502,668 shares of common stock remained available to be purchased under the 2017 Share Repurchase Program. The Company repurchased 3,255,814 and 921,299 shares for $105.0 million and $24.6 million under the 2017 Share Repurchase Program during the six months ended September 30, 2022 and 2021, respectively. On May 3, 2022, 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 (2022 Share Repurchase Program). The 2022 Share Repurchase Program will become effective once the 2017 Share Repurchase Program is completed. The Company is not obligated to acquire any specific amount of common stock within any particular timeframe as a result of the 2022 Share Repurchase Program. On May 9, 2022, the Company entered into accelerated share repurchase (ASR) agreements with Mizuho Markets Americas LLC and Wells Fargo Bank, National Association (the Dealers) to repurchase an aggregate of $150 million of the Company's common stock via accelerated stock repurchase transactions under the 2017 Share Repurchase Program. Under the terms of the ASR, the Company made a $75 million payment to each of the Dealers on May 10, 2022, and received an initial delivery of 1,627,907 shares from each of the Dealers, or 3,255,814 shares in the aggregate, which is approximately 70 percent of the total number of shares of the Company's common stock expected to be repurchased under the ASR. These shares were deducted under the 2017 Share Repurchase Program. The final number of shares repurchased under the ASR is dependent upon the average of the daily volume-weighted average prices of the Company’s common stock during the term of the ASR, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR. The delivery of additional shares of common stock to the Company or an additional delivery of shares of common stock or a cash payment, at NetScout's election, by the Company to the Dealers may be required. The final settlement of each of the ASR transactions is expected to occur no later than the end of the third quarter of the fiscal year ending March 31, 2023. In connection with the delivery of shares of the Company's common stock upon vesting of restricted stock units, the Company withheld 550,602 shares and 523,539 shares at a cost of $19.0 million and $15.0 million, respectively, related to minimum statutory tax withholding requirements on these restricted stock units during the six months ended September 30, 2022 and 2021, respectively. These withholding transactions do not fall under the share repurchase programs described above, and therefore do not reduce the number of shares that are available for repurchase under those programs.

Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted net income (loss) per share is calculated by dividing net income (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 the Company incurred a net loss during the six months ended September 30, 2021, all outstanding restricted stock units and performance-based restricted stock units have an anti-dilutive effect and are therefore excluded from the computation of diluted weighted average shares outstanding.

INCOME TAXES	INCOME TAXES Generally, the Company's effective tax rate differs from the U.S. federal statutory income tax rate primarily due to foreign withholding taxes and U.S. taxation on foreign earnings, partially offset by research and development tax credits, foreign tax credits, stock related compensation and the foreign derived intangible income deduction. The Company's effective income tax rates were 10.3% and 19.7% for the three months ended September 30, 2022 and 2021, respectively. The effective income tax rate for the three months ended September 30, 2022 differed from the effective tax rate for the three months ended September 30, 2021 primarily due to research and development tax credits, foreign tax credits, the foreign derived intangible income deduction, and U.S. taxation of foreign earnings, as well as a discrete benefit from stock compensation during the three months ended September 30, 2022. The Company's effective income tax rates were 15.3% and 5.7% for the six months ended September 30, 2022 and 2021, respectively. The effective income tax rate for the six months ended September 30, 2022 differed from the effective tax rate for the six months ended September 30, 2021 primarily due to research and development tax credits, foreign tax credits, the foreign derived intangible income deduction, and U.S. taxation of foreign earnings, as well as a discrete benefit from stock compensation during the six months ended September 30, 2022.

Revenue Recognition Policy	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 cybersecurity solutions for service provider and enterprise customers, which include hardware, software, and service offerings. The Company's product sales consist of software only offerings and offerings which include hardware appliances with embedded software that are essential to providing customers the intended functionality of the solutions. 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 the amount the Company deems probable of collection. 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 typically recognized upon fulfillment, 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. 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 the Company's 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 primarily on the performance obligation'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 performance obligations 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. SSP has primarily been established for product performance obligations as the average or median selling price the performance obligation was recently sold for, whether sold alone or sold as part of a bundle transaction. The Company reviews sales of the product performance obligations on a quarterly basis and
