Lumin Synchronization

You can use Tenable Lumin to quickly and accurately assess your Cyber Exposure risk and compare your health and remediation performance to other Tenable customers in your Salesforce industry and the larger population. Lumin correlates raw vulnerability data with asset business criticality and threat context data to support faster, more targeted analysis workflows than traditional vulnerability management tools. For more information about Lumin, see Lumin in the Tenable.io User Guide.

After you acquire a Tenable.io Lumin license for use with Tenable.sc, you can configure Tenable.sc synchronization to send limited Tenable.sc data to Tenable.io for use in Lumin analysis. Tenable.sc communicates with Tenable.io using an encrypted connection, as described in Encryption Strength.

When you send data to Tenable.io, the system does not remove the data from your Tenable.sc. You can continue normal operation of Tenable.sc.

Network Support

Supports accurate tracking of assets in repositories with overlapping IPv4 addresses.

Tip: The default setting for Network Support depends on the Tenable.sc version where you configured Lumin synchronization. For the purpose of determining the default setting for Network Support, Lumin synchronization is configured if you have configured the Tenable.io Connection Settings and selected at least one repository to synchronize.

  • Tenable.sc 5.18.x or earlier — Disabled by default if Lumin is already configured.

  • Tenable.sc 5.19.x or later — Enabled by default and cannot be disabled.

  • Enabled — Tenable.sc synchronizes each IPv4 repository and agent repository to its own network in Tenable.io, named TSC-Repository Name. You do not need to resolve repository overlaps if you enable Network Support.

    Note: Once enabled, you cannot disable Network Support.

  • Disabled — Tenable.sc synchronizes all repository data to the Default network in Tenable.io. You must resolve all repository overlaps before synchronizing your Tenable.sc data to Tenable.io.

For more information, see Networks in the Tenable.io User Guide.
