Tenable Vulnerability Management allows you to scan with one of three sensor types: Tenable's cloud scanners, Nessus scanners, or Nessus Agents.
If you need to scan assets that are external to your network, Tenable recommends using the cloud scanners. The cloud scanners are managed by Tenable, and do not require any upkeep from your organization. For more information, see Cloud Sensors.
To scan assets within your network, you can choose between scanning with Nessus scanners or Tenable Nessus Agents. The following table describes the key differences between scanning with Nessus scanners and Nessus Agents:

Ultimately, Tenable recommends using whichever sensor best suits your environment and business requirements. In many circumstances, you should use both agents and network assessments for different types of systems and parts of your network. To learn more about the benefits and limitations of agent scanning, see Benefits and Limitations in the Nessus Agent User Guide.
