This product is no longer available and has been replaced by Sophos offerings. The appliance features Layer 8 Technology, which treats user identity as the eighth layer in the protocol stack, enabling identity-based security policies and providing visibility into network activity by username rather than IP address alone. The device includes Extensible Security Architecture (ESA) for feature enhancements. Hardware specifications include 4 copper Gigabit Ethernet ports, 1 console port (RJ45), and 2 USB ports. Performance metrics include 1,500 Mbps UDP firewall throughput, 1,000 Mbps TCP firewall throughput, 150,000 concurrent sessions, and 5,000 new sessions per second. Security features include stateful inspection firewall, intrusion prevention system, gateway anti-virus and anti-spyware, anti-spam (inbound and outbound), web filtering, application visibility and control, and web application firewall. The device supports VPN connectivity through IPSec (100 tunnels, 210 Mbps throughput), SSL VPN (75 Mbps throughput), L2TP, and PPTP. Additional capabilities include bandwidth management, multiple link management, 3G/4G/WiMAx connectivity, IPv6 support, wireless security (IEEE 802.11 n/b/g), on-appliance reporting, and centralized management through Cyberoam Central Console (CCC) and iView solutions.
