Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Aerohive Networks, Inc. was incorporated in Delaware on March 15, 2006, and, together with its subsidiaries (the "Company"), has designed and developed a leading cloud networking platform and product portfolio using cloud management, machine learning and artificial intelligence to simplify and secure the access network. The Company's products include Wi-Fi access points, access switches and SD-WAN-capable routers required to build an edge-access network; a cloud services platform for centralized management; data collection and analytics; and applications that leverage the network to provide additional capabilities to the business and IT organizations. Our cloud-managed wireless, switching, routing and security technologies provide flexibility and scalability in the deployment, management and licensing of networks globally. The Company has offices in North America, Europe and Asia Pacific and employs staff around the world.
Basis of Presentation	The Company has eliminated all intercompany accounts and transactions in consolidation.
Significant Accounting Policies	There have been no material changes in the Company’s significant accounting policies, other than the adoption of accounting pronouncement noted below, as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018.
Consolidation	The Company prepared the accompanying condensed consolidated financial statements in accordance with generally accepted accounting principles in the United States ("GAAP"), which includes the accounts of Aerohive Networks, Inc. and its wholly owned subsidiaries.
Use of Estimates	Use of Estimates When preparing the accompanying consolidated financial statements in conformity with GAAP, management makes estimates and assumptions that affect the amounts the Company reports in the condensed consolidated financial statements and accompanying notes. Those estimates and assumptions include, among others, the determination of a standalone selling price ("SSP") for revenue arrangements with multiple performance obligations, determination of fair value of stock-based awards, inventory valuation, accounting for income taxes, including the valuation reserve on deferred tax assets and uncertain tax positions, allowance for sales reserves, allowance for rebate reserves, allowance for doubtful accounts, and warranty costs. Management evaluates estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. As the Company cannot determine future events and their effects with precision, actual results could differ from these estimates and assumptions, and those differences could be material to the consolidated financial statements
Foreign Currency	Foreign Currency The functional currency of the Company’s foreign subsidiaries is the U.S. dollar. The Company remeasures the transactions denominated in currencies other than the functional currency at the average exchange rate in effect during the reporting period. At the end of each reporting period, the Company remeasures its subsidiaries’ monetary assets and liabilities to the U.S. dollar using exchange rates in effect at the end of the reporting period. The Company remeasures its non-monetary assets and liabilities at historical exchange rates. The Company records gains and losses related to remeasurement in other income (expense), net in the condensed consolidated statements of operations. Foreign currency exchange gain (losses) has not been significant in any period presented and the Company has not undertaken any hedging transactions related to foreign currency exposure.
New Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standard Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-02, Leases (Topic 842), which supersedes the lease accounting requirements in Topic 840. On January 1, 2019, the Company adopted ASC 842 and the related subsequent accounting updates which require recognition of right-of-use ("ROU") assets and associated lease liabilities for most leases on the Company's consolidated balance sheets. The Company adopted the lease standard under the modified retrospective transition method which requires a cumulative-effect adjustment, if any, to the opening balance of retained earnings to be recognized on the date of adoption. There was no cumulative-effect adjustment recorded to retained earnings on January 1, 2019. Under the modified retrospective transition method, the Company did not restate financial information reported in periods prior to 2019. The Company elected the package of practical expedients permitted under the transition guidance, which allows the Company to carry forward its historical lease classification, its assessment on whether a contract is or contains a lease, and its indirect costs for any leases that exist prior to adoption of the new standard. The Company also elected to combine lease and non-lease components for all underlying classes of assets. For leases with a term of 12 months or less and with no purchase option the Company is reasonably certain to exercise, the Company elected the short-term lease exemption, which allows the Company not to recognize ROU assets or lease liabilities for qualifying leases existing at transition and new leases the Company may enter into in the future. The primary impact from the adoption of ASC 842 was the recognition of the ROU assets and lease liabilities for operating leases of $4.3 million and $4.6 million, respectively, on January 1, 2019 which included reclassification of prepaid rent and deferred rent as a component of the ROU asset. The adoption of this standard had no impact on the Company's condensed consolidated statements of operations and condensed consolidated statements of cash flows or debt-covenant compliance under its current agreements. See Note 5 Leases, Commitments and Contingencies for additional information. Leases The Company determines if an arrangement is a lease at inception. The Company evaluates the classification of leases at inception and as necessary at modification. The Company separately discloses operating lease ROU assets and liabilities on the Company's condensed consolidated balance sheets. Finance leases are included in property and equipment, accrued liabilities and other liabilities on the Company’s condensed consolidated balance sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. The Company recognizes operating lease ROU assets and lease liabilities at commencement date based on the present value of lease payments over the lease term. When readily determinable, the Company uses the rate implicit in the lease to discount lease payments; however, when the rate is not readily determinable, the Company uses the incremental borrowing rate based on the information available at commencement date in determining the present value of future lease payments. The operating lease ROU asset also includes any lease payments made prior to lease commencement and excludes lease incentives. Variable lease payments are expensed as incurred and are not included within the ROU asset and lease liability calculation. Variable lease payments primarily include reimbursements of costs incurred by lessors for common area maintenance and utilities. The Company's lease terms are the non-cancelable period including any rent-free periods provided by the lessor and include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. At lease inception, and in subsequent periods as necessary, the Company estimates the lease term based on its assessment of extension and termination options that are reasonably certain to be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company does not separate non-lease components from lease components for all underlying classes of assets. In addition, the Company does not recognize ROU assets and lease liabilities for short-term leases, which have a lease term of twelve months. Lease expense for short-term leases is recognized on a straight-line basis over the lease term. Recent Accounting Pronouncements In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. An impairment charge will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The standard is effective for fiscal years beginning after December 15, 2021, with early adoption permitted. The Company currently plans to adopt this standard in 2021 when it becomes effective.
Concentrations of Credit Risk and Significant Customers	Concentrations of Credit Risk and Significant Customers Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments and accounts receivable. The Company maintains cash equivalents in money market funds. The Company maintains short-term investments in U.S. treasuries, corporate securities, and commercial paper. The Company sells its products primarily to channel partners, which include distributors, value-added resellers ("VARs"), managed service providers ("MSPs"), and original equipment manufacturers ("OEMs"). The Company’s accounts receivable are typically unsecured and are derived from revenue earned from customers located in the Americas, Europe, the Middle East and Africa, and Asia Pacific. The Company performs ongoing credit evaluations to determine customer credit, but generally does not require collateral from its customers. The Company maintains reserves for estimated credit losses and these losses have historically been within management’s expectations.
