About Scanners

Cloud Scanners

Note: Tenable.io Cloud Scanners are not supported when deploying Tenable.io on-prem.

By default, Tenable.io is configured with region-specific Cloud Scanners. You can select these scanners when you create and launch scans.

The Tenable.io interface displays the following Cloud Scanners:

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

The following table identifies each Tenable.io Scanner and, for whitelisting purposes, its IP address range. These IP ranges are exclusive to Tenable, Inc.

Linked Scanners

Note: Nessus AMI Pre-Authorized scanners are not supported when deploying Tenable.io on-prem.

In addition to using Tenable.io scanners, you can also link Nessus and NNM scanners to Tenable.io.

The Linked Scanners page identifies scanners by scanner type (Nessus or NNM) and indicates if the scanners have Shared permissions.

Once remote scanners are linked to Tenable.io, those scanners can be added to Scanner Groups, managed, and selected when configuring scans.

To link a scanner to Tenable.io, see Scanners and Agents.
