Does Panther support Nessus Pro self-hosted on the Tenable native integration?
Panther's Tenable native integration supports pulling data from the domain https://cloud.tenable.com. If the domain is different, then the native integration will not work properly. If you are interested in support of this feature, please contact Panther Support to put in a request.
As a workaround, you can proceed with a manual upload of the logs using a custom log source.
