Juniper Networks, Inc. was an information technology and computer networking products multinational company, founded in 1996.^[1]

By 2001, Juniper had made only a few acquisitions of smaller companies, due to the leadership's preference for organic growth.^[2] The pace of acquisition picked up in 2001 and 2002 with the purchases of Pacific Broadband and Unisphere Networks.^[3] In 2004 Juniper made a $4 billion acquisition of network security company NetScreen Technologies.^[4] Juniper revised NetScreen's channel program that year and used its reseller network to bring other products to market.^[5]

Juniper made five acquisitions in 2005, mostly of startups with deal values ranging from $8.7 to $337 million. It acquired application-acceleration vendor Redline Networks, VOIP company Kagoor Networks, as well as wide area network (WAN) company Peribit Networks.^[6] Peribit and Redline were incorporated into a new application products group and their technology was integrated into Juniper's infranet framework.^[7][8]

From 2010 to September 2011, Juniper made six acquisitions and invested in eight companies. Often Juniper acquired early-stage startups, developing their technology, than selling it to pre-existing Juniper clients.^[9] Juniper acquired two digital video companies, Ankeena Networks and Blackwave Inc., as well as wireless LAN software company Trapeze Networks.^[9][10] In 2012, Juniper acquired Mykonos Software, which develops security software intended to deceive hackers already within the network perimeter.^[11] and a developer of software-defined network controllers, Contrail Systems.^[12] In 2014 Juniper acquired the software-defined networking (SDN) company WANDL.^[13]

Juniper Networks itself was acquired by Hewlett Packard Enterprise in July 2025.^[14][15] Following the acquisition, Juniper was absorbed into HPE Networking.^[16]
