Remote Filtering Server and Client

For all Web Filter and Web Security solutions, you can monitor computers outside your network using remote filtering components. The Remote Filtering Client must be installed on each remote machine.

The remote clients communicate with a Remote Filtering Server, which acts as a proxy to Filtering Service. This communication is authenticated and encrypted.

Note  If you have Websense Web Security Gateway Anywhere, you can also use the hybrid service to monitor users outside your network. This does not require software installation on remote machines. See Web Security Gateway Anywhere (software-based) or Web Security Gateway Anywhere (appliance-based) for more information.

When installing remote filtering components:

The Remote Filtering Server should be installed on a dedicated machine that can communicate with the Filtering Service machine.

Do not install any Websense component on a domain controller.

Remote Filtering Server on the same machine as Filtering Service or Network Agent.

Each Filtering Service instance can have only one primary Remote Filtering Server.

As a best practice, the Remote Filtering Server should be installed inside the outermost firewall, in the DMZ outside the firewall protecting the rest of the corporate network. This is strongly recommended.

See System Requirements, for operating system requirements for Remote Filtering Server.
