Sensors Overview supports the following sensor types:

  • Tenable-provided regional cloud scanners.
  • Manually configured linked sensors (Nessus scanners, NNM instances, Web Application Scanning sensors, and Nessus Agents)

Cloud Sensors

By default, Tenable provides regional cloud sensors. You can select these sensors when you create and launch scans.

The interface displays regional cloud sensors in the following groups:

  • US Cloud Sensor: A group of sensors from one US-EAST range (Ohio or Virginia) and the US-WEST range.
  • US East Cloud Sensors: A group of sensors from either the Ohio or Virginia US-EAST range.
  • US West Cloud Sensors: A group of sensors from the US-WEST range.
  • AP Singapore Cloud Sensors: A group of sensors from the Singapore AP-SOUTHEAST range.
  • EU Frankfurt Cloud Sensors: A group of sensors from the EU-CENTRAL range.

The following table identifies each regional cloud sensor and, for whitelisting purposes, its IP address ranges. These IP address ranges are exclusive to Tenable.

Linked Sensors

After you install a Nessus scanner, NNM instance, Web Application Scanning sensor, or Nessus Agent sensor, you can link it to

Before you can use linked sensors in scans, you must:

  1. Install the appropriate Tenable product on the sensor or the host you want to scan. For more information, see:

  2. Link the sensor or link the agent to

After linking a sensor, you can:
