If you have an on-premises installation of Forcepoint Web Security or Forcepoint URL Filtering, and your organization uses Microsoft Windows Active Directory, you can use DC Agent to identify users transparently. The agent periodically queries domain controllers for logon session information, and can be configured to poll client machines to verify logon status.

For DC Agent troubleshooting help, see the DC Agent Troubleshooting, available from support.forcepoint.com.
