ZyXEL Marches into Layer 7 Firewall Arena; ZyWALL IDP 10 Deters Intrusion for Small and Medium Businesses

Hsinchu, October 6, 2004--ZyXEL Communications (TSE:2391), world's leading broadband access solutions provider, demonstrates its first Intrusion Detection and Prevention (IDP) product designed exclusively for SMB. The ZyWALL IDP 10 employs the cutting-edge CPI (Complete Packet Inspection) technology that offers robust and accurate active, in-line mode defense mechanism. Designed with easy deployment and management in mind, ZyWALL IDP 10 can obtain various services through "ZyXEL Global Network Security Total Solution", and interact with ZyWALL Firewalls for tenacious SMB network security systems.

"The general-purpose firewalls may offer basic protections to the corporate intranets; however the application layer firewall, also known as IDP, should be deployed as well for neutralizing Layer 7 packet attacks or malwares before they cause any damage," said Albert Lee, Senior Product Manager of ZyXEL's Network Security & Applications Division. "In addition, the IDP can help blocking bandwidth-wasting applications, such as peer-to-peer transfer or instant messaging, to fully utilize the network resources. With highly efficient ZyWALL IDP 10 deployed outside the firewall gateway, or on all major intranet branches, server farms or WiFi network gateways, the corporate network assets can be protected effectively."

The ZyXEL ZyWALL IDP 10 supports the latest CPI (Complete Packet Inspection) technology with more accurate detecting capability than common DPI (Deep Packet Inspection) methods. With 1,600 attack signatures built-in, ZyWALL IDP 10 is capable of instantly detect and block attacks from network and application layers, such as DoS/DDoS, Buffer Overflow, Port Scan, Trojan Horse and Worm, etc.

In addition to the active and real-time detection, ZyWALL IDP 10 supports ZyXEL's proprietary "Stealth Mode" that cloaks ZyWALL IDP 10 on the network to avoid it becoming a target. Moreover, ZyWALL IDP 10 can check or download latest signature policies automatically for effective real-time protection.

ZyWALL IDP 10 boasts easy deployment and sophisticated management aside from its powerful security features. The bridge mode enables ZyWALL IDP 10 to deploy without altering current network structure and configurations, and the Web-based GUI simplifies the setup tasks as well. ZyWALL IDP 10 also supports instant attack notification, comprehensive attack event logs and system status logs for easier management.
