Aruba Networks
Aruba Networks is a networking and security business founded in California and now operated within Hewlett Packard Enterprise as HPE Aruba Networking.
Last updated August 22, 2026
Overview
Aruba Networks is a California-founded enterprise networking company whose business became part of Hewlett Packard Enterprise after HP acquired the company in 2015. It was established in Sunnyvale in 2002 by Keerti Melkote and Pankaj Manglik. The company developed a portfolio centered on wireless and wired network infrastructure, including network switches, wireless access points, wireless controllers, and hotspot solutions. Aruba's core market has been enterprise and institutional networking. Its products were designed to help organizations deploy and manage wireless local-area networks, connect users and devices, and control traffic across wired and wireless infrastructure. This placed the company in competition with other enterprise networking suppliers while giving it a distinct emphasis on wireless access and mobility-oriented networking. On March 2, 2015, Hewlett-Packard announced an agreement to acquire Aruba Networks for approximately US$3 billion. HP completed the transaction on May 19, 2015. Following Hewlett-Packard's separation into Hewlett Packard Enterprise and HP Inc., Aruba's networking and security activities became part of Hewlett Packard Enterprise's broader networking operations. From November 1, 2015, the business was described as the Intelligent Edge unit of Hewlett Packard Enterprise, bringing together networking and security assets and acquisitions associated with HP and HPE. The Aruba name continued to be used within HPE's networking portfolio, including the HPE Aruba Networking identity. This means that Aruba Networks is best understood today as an active HPE networking business and brand rather than as an independent, separately listed company. Its historical identity is associated with enterprise wireless networking, while its later role has been to provide a wider set of wired, wireless, security, switching, access, and network-management capabilities within HPE's portfolio. The business has also been affected by broader portfolio and regulatory decisions involving HPE. In connection with HPE's acquisition of Juniper Networks, HPE agreed to divest its Instant On technology and related patents under an arrangement with the United States Department of Justice intended to secure regulatory approval for that transaction. The divestiture illustrates that Aruba-related and adjacent networking technologies can be reshaped by competition-review requirements and corporate portfolio strategy.
History
Aruba Networks was founded in Sunnyvale, California, in 2002 by Keerti Melkote and Pankaj Manglik. From its beginning, the company concentrated on enterprise networking, particularly the infrastructure required to support wireless connectivity and mobile access. Its product range included network switches, wireless access points, wireless controllers, and hotspot solutions. The company's historical importance within enterprise networking came from its focus on integrating wireless access with the wider network environment. Rather than operating only as a provider of standalone connectivity devices, Aruba supplied multiple infrastructure components used to connect clients, manage wireless networks, and link wireless deployments with wired switching systems. This positioned the business within the enterprise networking and security market. A major turning point came on March 2, 2015, when Hewlett-Packard announced that it would acquire Aruba Networks for approximately US$3 billion. The acquisition was completed on May 19, 2015. The transaction brought Aruba into HP's networking portfolio and ended its independent status as a separately operated public-company-style business under its former identity. The subsequent separation of Hewlett-Packard into Hewlett Packard Enterprise and HP Inc. changed the organizational context in which Aruba operated. From November 1, 2015, Aruba was described as part of Hewlett Packard Enterprise's Intelligent Edge business unit. That unit combined Aruba's networking and security activities with other HP and HPE networking-related operations and acquisitions. The Aruba name consequently continued as a major product and business identity within HPE rather than disappearing after the acquisition. In its HPE form, the business has been associated with enterprise wired and wireless networking, switching, access infrastructure, security, and related network-management capabilities. The brand's development reflects the convergence of wireless access, switching, and security in corporate networks. It also reflects the way large technology companies use acquisitions to assemble broader infrastructure portfolios. The business has remained subject to portfolio review as HPE has pursued further expansion. In connection with HPE's acquisition of Juniper Networks, HPE agreed to divest Instant On technology and patents as part of an arrangement with the United States Department of Justice that enabled the acquisition to receive regulatory approval. This decision demonstrates how competition regulation can require technology divestitures even when the assets are part of a broader networking strategy. Aruba Networks is therefore both a historical company and an ongoing HPE brand identity. Its independent origins date to 2002, its corporate independence ended with the 2015 HP acquisition, and its present significance lies in its role within HPE Aruba Networking and the wider HPE networking and security portfolio.
