NetScreen Technologies was acquired by Juniper Networks for US$ 4 billion stock for stock in 2004.

 

NetScreen Technologies developed ASIC-based Internet security systems and appliances that delivered high performance firewall, VPN and traffic shaping functionality to Internet data centers, e-business sites, broadband service providers and application service providers. NetScreen was the first firewall manufacturer to develop a gigabit-speed firewall, the NetScreen-1000.

 

History

NetScreen Technologies was founded by Yan Ke, Ken Xie, and Feng Deng. Ken Xie, Chief Technology Officer and co-founder was also the CEO until Robert Thomas joined in 1998.

 

Robert Thomas, NetScreen's president and chief executive officer, came to NetScreen in 1998 from Sun Microsystems, where he was General Manager of Intercontinental Operations for Sun's software business, which includes security, networking, and Internet tools. 

 

Ken Xie left NetScreen in 2000 to found Fortinet, a competing ASIC-based firewall company.

 

In 2003 NetScreen hired Anson Chen as its vice president of research and development. Anson Chen, a 12 year veteran of Cisco Systems, Inc. and its former vice president and general manager of the Network Management and Services Technology Group, lead engineering, research and development efforts for NetScreen's entire product line, including its firewall, IPSec virtual private network (VPN) and intrusion detection and prevention technologies. Chen also had functional management responsibility for NetScreen's secure access products.

 

NetScreen acquired its core IPS technology through the purchase of OneSecure, Inc. for US$ 40 million in stock in 2002. OneSecure was created by Israeli engineer Nir Zuk, who previously was one of Check Point Software’s first employees and later went on to found Palo Alto Networks.

 

Aftermath

Yan Ke and Feng Deng stayed with Juniper after the acquisition but then left Juniper in 2005 and started Northern Light Venture Capital, a China concept venture capital firm focused on early and growth stage opportunities in TMT, consumer, clean technologies, and life science industries.

 

Nir Zuk stayed with Juniper after the acquisition but then left in 2005 to start a new company, Palo Alto Networks.Palo Alto Networks products are similar to OneSecure/NetScreen/Juniper's IPS technology as they share a common heritage.
