Superior Spyware Detection and Blocking Methods
The Barracuda Web Filter, previously known as the Barracuda Spyware Firewall, provides complete spyware protection for all downloads. It operates at the gateway and blocks drive-by installs or downloads as well as any installation from known spyware Web sites. The Barracuda Web Filter also attacks existing spyware installations by detecting any spyware access to the Internet, notifying the administrator and facilitating its removal.

The Energize Updates provided by Barracuda Central update the spyware rules and definitions every hour ensuring that your organization is completely protected from emerging threats.
