Blue Coat Introduces Anti-Spyware Appliance

Blue Coat plans on Monday to introduce a new spyware-blocking appliance for networks of 1,000 users or less.

Spyware Interceptor repackages the company's enterprise-level security appliance, removing technology not having to do with spyware defense and adding a graphical user interface for easy management, said product manager Chris Hargett. The appliance is designed to take about 15 minutes to install.

The appliance incorporates several spyware-fighting technologies, including filtering by category, white- and blacklisting, file type identification, port monitoring, and scanning outbound connections.

Blue Coat maintains directories of Web sites organized by categories. It uses the lists for content-filtering purposes, to allow companies to control which Web sites employees are allowed to visit. Blue Coat adapted that technology for spyware blocking, to allow network managers to block executable downloads from at-risk sites.

"Of the 60 or so content-filtering categories we have, the spyware was coming in from 15 high-risk categories," Hargett said. These include adult, gambling, gaming, politics and hobby-sports. For Blue Coat's list of categories it uses for Web filtering, see here.
