The FortiGuard filter enhances the web filter features by sorting billions of web pages into a wide range of categories that users can allow or block.
The FortiGuard Web Filtering service includes over 45 million individual website ratings that apply to more than two billion pages. When the FortiGuard filter is enabled in a web filter profile and applied to firewall policies, if a request for a web page appears in traffic controlled by one of the firewall policies, the URL is sent to the nearest FortiGuard server. The URL category or rating is returned. If the category is blocked, the FortiGate shows a replacement message in place of the requested page. If the category is not blocked, the page request is sent to the requested URL as normal.
To use this service, you must have a valid FortiGuard license.
