Virginia Hospital Center Deploys NetScreen Firewall/VPN and Intrusion Detection and Prevention Solutions

Sunnyvale, CA - September 29, 2003 - NetScreen Technologies, Inc. (Nasdaq: NSCN) today announced that the Virginia Hospital Center, a teaching hospital long-associated with Georgetown University’s School of Medicine, has deployed NetScreen’s firewall and virtual private network (VPN) appliances, as well as the company’s intrusion detection and prevention (IDP) systems to secure its Internet gateway and establish secure connections for remote offices and telecommuters to the central hospital network.

The new NetScreen-based security infrastructure replaced devices from two different vendors that were separately providing firewall and VPN functionality, complicating the security network architecture and management.

“Our previous software-based firewalls were not easily configurable and did not work with our VPN solutions. Additionally, there was no central management for our security network,” said Mark Rein, director of IT at Virginia Hospital Center. “With NetScreen, we now have centralized network security management and integrated, flexible devices that are easy to deploy, configure and manage.”

Virginia Hospital Center installed NetScreen-204 appliances at its primary Internet gateway to provide firewall protection of critical resources and serve as a VPN tunnel concentrator. The NetScreen-204 offers 400 Mbps of firewall performance, with support for 128,000 sessions. Physicians and other hospital officials needing secure connections to critical hospital data from their homes or remote offices use either NetScreen-5XP appliances, which offer a cost effective solution for remote offices, or NetScreen-Remote VPN Client software installed on their laptops. Sitting within the network core are NetScreen-IDP 100 appliances, which provide up to 200 Mbps throughput and operate in-line to detect and drop malicious traffic in real-time before it reaches its victim, minimizing the impact of an attack.

By replacing its Check Point/Nokia firewalls and Cisco VPNs with NetScreen appliances, Virginia Hospital Center has seen numerous benefits including centralized security. With NetScreen, Rein commented, “we now have centralized network security management that’s flexible and easy to manage.”
