License Requirements

For information on how to obtain a Tenable Enclave Security license, see Licenses.

This topic breaks down the licensing process for Tenable Enclave Security. It also explains how assets are counted, lists add-on components you can purchase, and describes what happens during license overages or expirations. To learn how to use Tenable Enclave Security, see the Tenable Enclave Security User Guide.

Licensing Tenable Enclave Security

To use Tenable Enclave Security, you purchase licenses based on your organizational needs and environmental details. Tenable Enclave Security assigns those licenses to your assets, which are assessed hosts from Container Security or Security Center.

When your environment expands, so does your asset count, so you purchase more licenses to account for the change. Tenable licenses use progressive pricing, so the more you purchase, the lower the per-unit price. For prices, contact your Tenable representative.

Note: Tenable offers simplified pricing to managed security service providers (MSSPs). To learn more, contact your Tenable representative.

Tenable Enclave Security Products

The following table lists Tenable Enclave Security products that require licenses, along with the asset type licensed.

Product Asset Type

Reclaiming Licenses

When you purchase Tenable licenses, your total license count is static for the length of your contract unless you purchase more licenses. However, Tenable Enclave Security products reclaim licenses under some conditions—and then reassign them to new assets in the same product so that you do not run out of licenses.

The following table explains how each Tenable Enclave Security product reclaims licenses.

Exceeding the License Limit

To allow for usage spikes due to hardware refreshes, sudden environment growth, or unanticipated threats, you can temporarily exceed your license limits in Tenable Enclave Security:

  • Tenable Security Center - You can temporarily exceed your licensed IP address count by 10%. If you exceed this number, Tenable Security Center is disabled.

  • Tenable Enclave Security Container Security - When you scan more assets than you have licensed, Tenable clearly communicates the overage and then reduces functionality in three stages:

    Scenario Result
    You scan more assets than are licensed for three consecutive days. A message appears in Tenable Enclave Security.
    You scan more assets than are licensed for 15+ days. A message and warning about reduced functionality appears in Tenable Enclave Security.
    You scan more assets than are licensed for 45+ days. A message appears in Tenable Enclave Security; scan and export features are disabled.

Tenable Enclave Security generates a warning in the user interface when you approach or exceed the license limit.

Tip: Improper scan hygiene or product misconfigurations can cause scan overages, which result in inflated asset counts. To learn more, see Scan Best Practices.

Expired Licenses

The Tenable Enclave Security licenses you purchase are valid for the length of your contract. 30 days before your license expires, a warning appears in the user interface. During this renewal period, work with your Tenable representative to add or remove products or change your license count.

After your license expires, you can no longer sign in to the Tenable platform.
