Make sure you create a Local Account of Administrator from type Application on the Forcepoint Security Manager and apply the authentication process before using the service.
To connect an application to Forcepoint DLP through a REST API connection, you need to create an Application administrator in the Forcepoint Security Manager on the
Global Settings > General > Administrators settings page. For more information, see the
Enabling access to the Security Manager topic in the Forcepoint Security Manager Help. The Application administrator type is only supported for Local accounts. Please note that Network accounts cannot be configured as an Application type.
