Integrating Forcepoint URL Filtering using ICAP Service

ICAP Service makes it possible to integrate Forcepoint URL Filtering with third-party proxies and proxy-caches that support communication with ICAP servers.

Integration via ICAP affects the following web protection components:

• ICAP Service is installed with Filtering Service. It includes an ICAP server that enables third-party proxies to communicate with Filtering Service.
• Filtering Service interacts with ICAP Service and Network Agent to respond to Internet requests passed from the proxy via ICAP.

For installation instructions, see Installing Forcepoint URL Filtering to integrate with ICAP Service.

After installing your web protection software, configure your proxy to communicate with ICAP Service (see Configuring the proxy to communicate with ICAP Service).

ICAP Service may also require configuration (see Configuring ICAP Service) if the default settings are not appropriate for your environment.

To have Internet requests managed by Forcepoint URL Filtering, a computer must access the Internet through the integrated proxy.

When the proxy receives an Internet request, it uses ICAP to query ICAP Service to find out if the request should be blocked or permitted. ICAP Service queries Filtering Service, which checks the policy assigned to the client and either serves a block page or notifies the proxy to permit the request.
