Application filters are extensions of the Microsoft Firewall service. These filters register for and process Firewall service events. By exposing COM interfaces to developers, Forefront Threat Management Gateway (TMG) allows you to extend its security and functionality.

These filters can share the architecture, access control, and administration of the Firewall service.
