Tenable.io Vulnerability Management Licenses
Your Tenable.io 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.io to scan your assets before adjusting your license as needed.
You can view your license information to see how many assets are currently being counted against your Tenable.io license. You can use this information to evaluate how effectively you are using your asset licenses.
To understand licenses, see the following sections:
Note: You can use the Is Licensed (VM) advanced search filter to view assets that currently count against your Tenable.io license. For more information, see Filter a Table.
Tenable.io analyzes multiple asset attributes, not just IP addresses, to identify an asset. For more information on how Tenable.io identifies an asset, see the Tenable.io FAQ.
Assets are counted towards your license limit depending on how Tenable.io discovers, or sees, the asset. In general, an asset does not count against your license limit unless it has been assessed for vulnerabilities.

Conditions where an asset counts towards your license limit can include:
Conditions where an asset does not count towards your license limit can include:
When Tenable.io reclaims a license, that license becomes available for a different asset. Tenable.io reclaims licenses in the following scenarios:
- When a licensed asset has not been scanned for 90 days, it ages out of the license count.
If an asset was discovered through connectors and subsequently became licensed, the asset license is reclaimed the day after the asset is terminated. You can observe this event via the connector.
You can monitor licenses that are expected to be reclaimed in your License Information.
The following plugins do not count towards the license limit.
Note: Plugin IDs are static, but Tenable.io occasionally updates plugin names. For the latest information on plugins, see https://www.tenable.com/plugins.
