Sophos Expands Hardware Security Offering
by Janet Harris
Sophos Plc has released a second hardware appliance which quickly scans Internet sites for malware.
The WS1000 Web security appliance provides application control and URL filtering in a 1U rack-mounted unit powered by an Intel dual core processor.
Sophos developed the WS1000 following its $23m acquisition of enterprise software developer ActiveState in 2003, which lead to the creation last April of the Sophos ES4000 e-mail security appliance.
Most software tools block malware but Sophos and other companies believe their work can be automated and done faster through an appliance.
The WS1000 appliance can be installed in-line. It includes a database linked to Sophos which can detect malware signatures, block malicious hosts and identify infected machines behind the firewall. It can also control incoming streaming media.
The device’s management software breaks down threats into three categories: known (which are blocked), new (transitory Web sites that have malicious code) and unknown (sites with code identified as suspicious through behaviour analysis).
Administrators can set appropriate policies for sites via a console, based on whether a site is a high/medium/low threat or trusted. Users can send a message to the administrator objecting to a site’s classification. The console includes a search tool to help process the messages. It also reports Web traffic statistics.
The Linux-based appliance runs on the Sophos single-pass anti-virus software engine, and includes two 160Gb SATA hard drives for database storage. It also includes a Network bypass card with shared configuration failover capability
The price of the device ranges from US$5,400 for up to 500 users a year to US$8,000 for up to 1,000 users.
