Scanners and Agents
Scanners and agents collect data to be reported by Tenable.io.
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 scanners, NNM scanners, and Nessus Agents to Tenable.io.
Once linked to Tenable.io, use the Tenable.io key to add 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.
Agents increase scan flexibility by making it easy to scan assets without needing ongoing host credentials or assets that are offline. Additionally, agents enable large-scale concurrent scanning with little network impact.
