Juniper Networks

Juniper Networks, Inc., was an American multinational corporation headquartered in Sunnyvale, California. The company developed and marketed networking products, including routers, switches, network management software, network security products, and software-defined networking technology. The company was founded in 1996 by Pradeep Sindhu, with Scott Kriens as the first CEO, who remained until September 2008. Kriens has been credited with much of Juniper's early market success. It received several rounds of funding from venture capitalists and telecommunications companies before going public in 1999. Juniper grew to $673 million in annual revenues by 2000. By 2001 it had a 37% share of the core routers market, challenging Cisco's once-dominant market-share. It grew to US$4 billion in revenues by 2004 and $4.63 billion in 2014. Juniper appointed Kevin Johnson as CEO in 2008, Shaygan Kheradpir in 2013 and Rami Rahim in 2014. Juniper Networks originally focused on core routers, which are used by internet service providers (ISPs) to perform IP address lookups and direct internet traffic. Through the acquisition of Unisphere, in 2002, the company entered the market for edge routers, which are used by ISPs to route internet traffic to individual consumers. In 2003, Juniper entered the IT security market with its own JProtect security toolkit before acquiring security company NetScreen Technologies the following year. In the early 2000s, Juniper entered the enterprise segment, which accounted for one-third of its revenues by 2005. From 2014 to 2025, Juniper was focused on developing new software-defined networking products. In January 2024, Juniper agreed to be acquired in full by Hewlett Packard Enterprise (HPE) for approximately $14 billion. The acquisition closed on July 2, 2025.
