SUNNYVALE, CA - December 4, 2003 - NetScreen Technologies, Inc. (Nasdaq: NSCN) today announced that it has been ranked as a market leader in META Group’s recently released METAspectrum℠ for enterprise firewalls. META Group (Nasdaq: METG) is a leading research and consulting firm that focuses on information technology and business transformation strategies.

NetScreen was positioned in the leadership segment of the METAspectrum analysis, and was specifically recognized for its successful track record of anticipating and executing upon market and technology inflection points, such as pioneering the movement to purpose-built, hardware-based firewall solutions and adding intrusion prevention functionality to its integrated firewall and virtual private network (VPN) solutions, bolstering network- and application-level attack protection. Additionally, NetScreen was recognized for its firewall product’s technology, including superior performance and high availability capabilities.

“We developed METAspectrum to enable IT professionals to quickly evaluate vendors based on their ability to deliver on the presence and performance criteria that matter most in a given market,” said Mark Bouchard, senior research analyst for META Group. “Application-layer awareness/control and intrusion prevention are becoming the next big rallying cries for the enterprise firewall market.”
