| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements include those of A10 Networks, Inc. and its subsidiaries after elimination of all intercompany accounts and transactions. We have prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). As permitted under these rules and regulations, we have condensed or omitted certain financial information and footnote disclosures we normally include in our annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The unaudited condensed consolidated balance sheet as of December 31, 2024 has been derived from our audited financial statements, which are included in our 2024 Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on February 25, 2025 (the “2024 Annual Report”). These financial statements have been prepared on the same basis as our annual financial statements and, in management’s opinion, reflect all adjustments consisting only of normal recurring adjustments that are necessary for a fair presentation of our financial information. Our interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the financial statements and accompanying notes thereto in the 2024 Annual Report.

| Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Those estimates and assumptions affect revenue recognition and deferred revenue, the allowance for credit losses for potential uncollectible amounts, the sales return reserve, the valuation of inventory, the fair value of marketable securities, contingencies and litigation, accrued liabilities, deferred commissions, ThreatX Protect purchase price allocation and the determination of fair value of stock-based compensation. These estimates are based on information available as of the date of the condensed consolidated financial statements, therefore, actual results could differ from management’s estimates.

| Concentration of Credit Risk and Significant Customers | Concentration of Credit Risk and Significant Customers Financial instruments that potentially subject us to concentrations of credit risk consist of cash, cash equivalents, marketable securities and accounts receivable. Our cash, cash equivalents and marketable securities are held and invested in high-credit quality financial instruments by recognized financial institutions and are subject to minimum credit risk. Our accounts receivable are unsecured and represent amounts due to us based on contractual obligations of our customers. We mitigate credit risk in respect to accounts receivable by performing periodic credit evaluations based on a number of factors, including past transaction experience, evaluation of credit history and review of the invoicing terms of the contract. We generally do not require our customers to provide collateral to support accounts receivable. Significant customers, including distribution channels and direct customers (“end-customers”), are those which represent 10% or more of our total revenue for each period presented or our gross accounts receivable balance as of each respective balance sheet date. A substantial portion of our revenue is from sales of our products and services through distribution channels, such as resellers and distributors. In the three months ended June 30, 2025 and 2024, sales through a single distribution channel partner represented 32% and 23% of our total revenue, respectively. In the six months ended June 30, 2025, sales through a single distribution channel partner represented 25% of our total revenue and in the six months ended June 30, 2024, sales through two distribution channel partners represented 20% and 10% of our total revenue, respectively.

| Deferred Contract Acquisition Costs | Deferred Contract Acquisition Costs We capitalize certain contract acquisition costs consisting of incremental sales commissions incurred to obtain customer contracts. Deferred commissions related to product revenues are recognized upon transfer of control to customers. Deferred commissions related to services revenue are recognized as the related performance obligations are met. Deferred commissions that will be recognized during the succeeding 12-month period are recorded as prepaid expenses and other current assets, and the remaining portion is recorded as other non-current assets. Amortization of deferred commissions is included in sales and marketing expense.
