Deploy Umbrella's PAC File for Windows

Suggest Edits

Umbrella's secure web gateway requires that you deploy a proxy auto-config (PAC) file URL so that your browser is able to successfully reach destinations. If you're behind a firewall, you may also need to deploy Umbrella's PAC file to configure the browser so that it points to the correct proxy server.

Umbrella copies internal domains configured in the Umbrella dashboard (Deployments > Configuration > Domain Management) to the PAC file so that these internal domains are not sent to the proxy.
