You can use scanner groups to organize and manage the scanners linked to your Tenable Vulnerability Management instance. For example, you can add all sensors related to a specific geographical location to a group, for example, a group named "East Coast Scanners."
You can add a scanner to one or more scanner groups.
When you create a scan, you can select the scanner group to use to launch the scan. Alternatively, you can select Auto-Select to enable scan routing for the scan, which assigns scans to scanners based on the targets configured in scanner groups.
Tenable Vulnerability Management determines which scanner in a scanner group to use based on the following criteria:
- The scanner is active and has communicated to Tenable Vulnerability Management within the last 5 minutes.
- The scanner is running the lowest number of active scans and is scanning the lowest number of hosts.
Note: If your organization uses scan networks, you can only add scanners to scanner groups that belong to the same network. For more information, see Networks.
Note: If a remote scanner is part of a Scanner Group and is unlinked during its operations, the scan's operations complete, but Tenable Vulnerability Management does not include the unlinked scanner for future use.
