How Websense filtering works with ISA/TMG

To be filtered by Web Filter or Web Security, a computer must access the Internet through ISA/TMG.

When ISA/TMG receives an Internet request from a user, it communicates with Websense Filtering Service to find out if the requested site should be blocked or permitted. Filtering Service checks the policy assigned to the client. Each policy designates specific time periods and lists the category filters that are applied during those periods.

After Filtering Service determines which categories are blocked for that client, it checks the Websense Master Database.

If the site is assigned to a blocked category, the client receives a block page instead of the requested site.

If the site is assigned to a permitted category, Filtering Service notifies ISA/TMG that the site is not blocked, and the client is given access to the site.
