New NetScreen-5XT Features Enhance Security and Resiliency for Remote Sites

Guildford, U.K., Nov. 11, 2002 — NetScreen Technologies, Inc. (Nasdaq: NSCN), has announced new features for the NetScreen-5XT that increase the level of security and resiliency provided for enterprises looking to secure remote sites and telecommuters. In addition to a new Restricted Zone feature, other capabilities include fail-over and fail-back functionality as well as expanded router interoperability.

The new Restricted Zone feature enables remote sites to establish two security segments to isolate different internal networks or PCs from one another. For example, a retailer can establish a restricted zone to connect computers handling mission-critical point-of-sale transactions while allowing the other ports on the NetScreen-5XT to be used for customer-facing Internet-enabled kiosks. In a small office or telecommuter environment, a work PC can be segmented from other PCs to ensure that only the work PC can access the corporate virtual private network (VPN).

“Remote sites with multiple connection requirements often create unique problems for the network manager,” said David Flynn, vice president of marketing at NetScreen. “The new software for the NetScreen-5XT not only increases the overall security and resiliency for highly distributed enterprises, it eases management and deployment for administrators, minimizing the time and costs associated with addressing remote issues.”

New intelligent fail-over capabilities provide the ability to configure two “untrusted” interfaces that can be connected to two different ISPs, allowing communications to fail over to the second service provider in the event that the first provider suffers an outage. This complements a dial back-up feature NetScreen announced in July, whereby, in the event of a service-provider failure, a secure dial-up Internet connection can be established.

To ease deployment of the device, NetScreen also broadened the routing protocols supported by the NetScreen-5XT to include Routing Information Protocol version 2 (RIPv2), a widely used protocol for managing routing information within a local area network (LAN) or an interconnected group of LANs. The NetScreen-5XT already supports BGP and OSPF routing.

The new ScreenOS for the NetScreen-5XT will be available starting Nov. 8, 2002. For more information about the NetScreen-5XT, visit:
