License Requirements

Tenable.sc Director does not support an unlicensed demo mode. License keys are required for Tenable.sc Director and for all attached Tenable products. You first configure your Tenable.sc Director license and additional Tenable product licenses during quick start, as described in Quick Setup.

You can update your Tenable.sc Director license in an externally connected or air-gapped environment, as described in Update an Existing License.

Tenable.sc Director requires an internet connection to validate additional Tenable product licenses. To apply a license for an additional Tenable product, see Apply a New License. To update a license for an additional Tenable product, see Update an Existing License.

You cannot upgrade a Tenable.sc license to a Tenable.sc Director license or downgrade a Tenable.sc Director license to a Tenable.sc license.

Tip: For information about Tenable.sc-Tenable product registration server communications encryption, see Encryption Strength.

Your Tenable.sc License

Tenable.sc Director 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.sc discovers, or sees, the asset. In general, an asset does not count against your license limit unless it has been assessed for vulnerabilities.

For example, if you purchase a 500 asset Tenable.sc Director license, you can perform host discovery on your network but you cannot assess more than 500 assets. For more information about discovery and assessment scanning, see Scanning Overview.

Tenable.sc Director generates a warning in the web interface when you approach or exceed the license limit. To monitor your license limit, use the Licensing Status widget, as described in Overview Dashboard. To upgrade your license, contact your Tenable representative.

  • IP addresses from active scans
  • IP addresses from Log Correlation Engine instances
  • IP addresses from NNM instances not in discovery mode

  • IP addresses in offline repositories that you downloaded using the same Tenable.sc instance or license

A single IP address or UUID counts once toward your license, even if it was scanned by multiple methods or stored in multiple repositories.

Note: If you use an alternative port scanner, Tenable.sc Director counts the detected IP addresses against your license.

  • IP addresses present only from imports to offline repositories
  • IP addresses present only from NNM instances in discovery mode
