NetScreen Announces Agreement with RadioShack to Serve as Network Security Vendor

Sunnyvale, CA - March 8, 2004 - NetScreen Technologies, Inc. (Nasdaq: NSCN) today announced that RadioShack Corporation (NYSE: RSH) has selected NetScreen’s integrated firewall and virtual private network (VPN) security solutions to protect and securely connect its 5,200 retail stores within its corporate network.

“It was imperative for us to select a network security vendor that can accommodate multiple virtual local area networks (VLANs) and facilitate efficient management, content filtering and antivirus protection,” said Ron Cook, vice president, technology strategy and operations at RadioShack. “NetScreen gives us all these with the added bonus of Deep Inspection firewall technology. No other vendor was able to offer us the breadth of protection that NetScreen does.”

RadioShack selected multiple NetScreen-5200 systems, which provide up to 4 Gbps firewall and up to 2 Gbps of 3DES VPN throughput, to be deployed at the Fort Worth, Texas, headquarters to protect RadioShack’s critical network resources and data traversing its highly distributed corporate network.

NetScreen-5200 systems offer a Virtual Systems feature that enables up to 500 separate security domains to be created and operated from a single platform. As a result, retail stores can be segmented within the RadioShack network and unique security policies applied to each, protecting them accordingly from attempted breaches launched internally or externally.

RadioShack also will deploy NetScreen-5GT appliances to provide firewall, VPN and antivirus functionality in more than 5,000 retail stores located throughout the United States. The NetScreen-5GT appliance provides up to 75 Mbps firewall and up to 20 Mbps of 3DES VPN performance along with antivirus and Deep Inspection firewall functionality.

To manage the devices and security policies, RadioShack will use NetScreen’s central management platform.
