NetScreen Named SSL VPN Market Leader by Independent Research Firm

Report States NetScreen Provides Best Overall Solution

Sunnyvale, CA - March 30, 2004 - NetScreen Technologies, Inc. (Nasdaq: NSCN) today announced that Forrester Research has named NetScreen as the leading vendor in the rapidly growing SSL virtual private network (VPN) market. NetScreen was among eight select companies that Forrester invited to participate in its March 29 Forrester Wave report, titled “Making SSL VPNs a Strategic Part of Your Network”.

In this evaluation, NetScreen was cited as the leader of the overall SSL VPN market. The findings were based on NetScreen’s strong product offering, sound strategy, and large market presence, according to the Forrester Wave report, prepared by Forrester Research analyst Robert Whiteley. The report also stated:

NetScreen’s Secure Access Series contains the strongest overall feature set, the strongest support for applications in a clientless browser, several form factors that include FIPS-compliant versions, and a very extensive endpoint checking system called Host Checker. NetScreen also has a bold vision for SSL VPNs as a strategic part of a network - securing applications on both the WAN and LAN. As the clear market leader, NetScreen is the best all-around choice. Enterprises can leverage the combination of expertise in SSL VPN deployments and the backing of a company with established IPSec and security products.

“We are thrilled that NetScreen has been named the SSL VPN market leader by Forrester Research,” said Jason Matlof, vice president of marketing for NetScreen’s secure access products. “This recognition, along with the other industry accolades and competitive product reviews we’ve recently won, demonstrates our leading position in the SSL VPN market, the soundness of our strategy and road map, and the breadth of the security and SSL-based enterprise access functionalities in our products.”

NetScreen’s Secure Access Appliances

The NetScreen Secure Access (SA) appliances, which have earned the most awards and industry accolades in the SSL VPN market since first shipping in 2001, represent the market’s leading SSL VPN product line. Enterprises worldwide have selected the NetScreen-SA 1000, -SA 3000 and -SA 5000 products because they enable cost-effective deployment of secure access to remote employees, corporate partners and intranet users.

The NetScreen Secure Access appliances provide application-layer access, stringent access controls, and granular auditing and reporting capabilities to minimize IT headaches and security concerns. The SSL-based platform offers enterprise-class high availability and performance scalability options so secure access can be deployed on a wide scale, which can reduce user downtime and lost productivity, and can improve network performance.
