By default, Tenable.io is configured with a regional, specific cloud scanner. In addition to using the default cloud scanner, users can also link Nessus instances, NNM instances, and Nessus Agents to Tenable.io. These linked sensors are called "remote scanners." For more information, see Link a Scanner.
Once linked to Tenable.io, you can add the remote scanners to Scanner Groups. You can also manage and select remote scanners when configuring scans.
The Linked Scanners page displays scanner names, types, and permissions.
The Scanners page displays the Linking Key and a list of remote scanners. You can click on a linked scanner to view details about that scanner.
Scanners are identified by scanner type and indicate if the scanner has Shared permissions.
Remote scanners can be linked to Nessus Manager with the Linking Key or valid account credentials. Once linked, scanners can be managed locally and selected when configuring scans.
