Licensing

This topic describes the differences between licensing models in Tenable One Vulnerability Management and Tenable Security Center.

Tenable One Vulnerability Management

Your Tenable One Vulnerability Management Tenable One Vulnerability Management instance has a licensed asset limit, which determines the number of assets you can scan for vulnerabilities. If you exceed your license limit, you can temporarily continue to use Tenable One Vulnerability Management to scan your assets before adjusting your license as needed.

Tenable One Vulnerability Management licenses asset sand uses a “flexible” licensing model:

• Tenable One Vulnerability Management attempts to resolve duplicates. For example, a file server with 5 IP addresses - all of which are being scanned – only consumes a single license.

• Users are not locked out of the product due to license overages

For more information, see Vulnerability Management Licenses in the Tenable One Vulnerability Management User Guide.

Tenable Security Center

Tenable Security Center licenses are valid for a specific hostname and for a maximum number of active assets (identified by IP address or UUID). Assets are counted towards your license limit depending on how Tenable Security Center discovers, or sees, the asset. In general, an asset does not count against your license limit unless it has been assessed for vulnerabilities.

Because Tenable Security Center licenses IP addresses:

• A single asset with multiple IP addresses consumes multiple licenses.

• Users are locked out of the product if license usage exceeds the allotted number of licenses.
