Fulfilling a promise it made earlier in the year, Symantec will next month release a new line of gateway security appliances, the Symantec Gateway Security Appliance 5400 Series.

The release is scheduled for 9 September and will add to Symantec's family of Gateway Security Appliances, which combine firewall, intrusion detection, content filtering and antivirus technologies on a single hardware device.

Symantec has been touting the release of the 5400 for months. In comments tied to recent earnings releases, Chief Executive Officer John Thompson has said that the products would add the ManHunt intrusion detection system (IDS) engine to the Gateway Security Appliance platform. Symantec acquired the ManHunt technology with its purchase of Recourse Technologies in July, 2002.

Like earlier editions of the Gateway Security Appliance, 5400 series appliances will offer high availability features such as load balancing and clustering as well as event reporting capabilities, said Symantec.

The new appliances will be able to scale to manage traffic from 200Mbit/s up to 3.5Gbit/s, the company said.
