Juniper Networks, Inc. was a global enterprise specializing in information technology and computer networking, established in 1996.

Until 2001, Juniper primarily pursued organic expansion with minimal acquisitions. However, acquisition efforts intensified during 2001–2002, marked by the procurement of Pacific Broadband and Unisphere Networks. In 2004, Juniper purchased network security firm NetScreen Technologies for $4 billion, utilizing NetScreen’s reseller channels to enhance its product reach.

In 2005, Juniper acquired five emerging companies, including Redline Networks, an application acceleration provider; Kagoor Networks, a VOIP specialist; and Peribit Networks, focused on WAN technology. The innovations from Peribit and Redline were incorporated into Juniper’s infranet architecture within a newly formed application product division.

From 2010 through 2011, Juniper completed six acquisitions and invested in eight startups, concentrating on early-stage ventures to develop technologies aligned with its client base. Significant purchases included digital video companies Ankeena Networks and Blackwave Inc., wireless LAN software vendor Trapeze Networks, security software creator Mykonos Software (2012), and software-defined networking controller developer Contrail Systems (2012). In 2014, Juniper expanded its carrier portfolio by acquiring SDN firm WANDL.

In July 2025, Hewlett Packard Enterprise acquired Juniper Networks for $14 billion. Following this transaction, Juniper was merged into HPE Networking.
