Installation Supplement for Microsoft ISA Server or Forefront TMG Integrations

Version 7.5

This supplement to the Websense Web Security and Websense Web Filter Installation Guide provides information specific to integrating Websense software with Microsoft® Internet Security and Acceleration (ISA) Server and Forefrontâ„¢ Threat Management Gateway (TMG). Refer to the Installation Guide as your primary source of installation instructions. Only additional or alternate steps required to integrate Websense software with ISA/TMG are provided here.

An integration with ISA/TMG affects the following Websense components:

* Websense ISAPI Filter plug-in: This additional Websense component is installed on the machine running ISA/TMG. The ISAPI Filter plug-in configures ISA/TMG to communicate with Websense Filtering Service.
* Websense Filtering Service: Interacts with ISA/TMG and Websense Network Agent to filter Internet requests. Filtering Service either permits the Internet request or sends an appropriate block message to the user.
