You can download the update files from the Tenable.sc Downloads page.

Upgrade Notes

If you are running Tenable.sc 5.12.0 or later, you can upgrade directly to Tenable.sc 5.22.0. If you are running a version earlier than Tenable.sc 5.12.0, upgrade to Tenable.sc 5.12.0 before upgrading to Tenable.sc 5.22.0.

If you are running Tenable.sc 5.22.0 and you are using pyTenable with the Tenable.sc API, you must upgrade pyTenable to version 1.4.2 or later.

If you upgrade Tenable.sc Director, upgrade Tenable.sc for all managed Tenable.sc instances connected to Tenable.sc Director. After upgrading, allow up to 15 minutes for your managed Tenable.sc instances to sync with Tenable.sc Director.

Tenable recommends performing a backup before upgrading Tenable.sc. For more information, see Perform a Backup in the Tenable.sc User Guide.

Note: This release includes a fix for a potential vulnerability. For more information, see the Tenable Product Security Advisory.

Note: If your upgrade path skips versions of Tenable.sc (for example, upgrading from 5.9.0 to 5.12.0 to 5.22.0), Tenable recommends reviewing the release notes for all skipped versions. You may need to update your configurations because of features and functionality added in skipped versions.

Note: Tenable.sc 5.21.0 is the last version of Tenable.sc that supports Internet Explorer. For more information about other supported browsers, see Web Browser Requirements in the Tenable.sc User Guide.

New Features

Domain Discovery

All Tenable.sc customers now have the ability, through an integration with Tenable.asm, to discover new internet-facing assets, domains, subdomains, and more. This capability is available to all Tenable.sc customers and will allow customers to actively search two top level domains at a time. All data will be refreshed every 90 days.

For more information, see Attack Surface Domain Discovery in the Tenable.sc User Guide.

BCC Emails during Report Generation

Customers will now be able to BCC emails when they create new reports in Tenable.sc.

For more information, see Report Options in the Tenable.sc User Guide.

Touch Debugging Logs

Touch Debugging Logs will now be known as Debugging Logs. Additionally, customers will now have the ability to download them directly from the Tenable.sc GUI.

For more information, see Diagnostics Settings in the Tenable.sc User Guide.

Back Button for Picture in Picture

Customers will now have a Back button which will allow them to easily exit a Picture in Picture session without closing the page and opening a new Tenable.sc session.

For more information, see View Nessus Instances in Tenable.sc in the Tenable.sc User Guide.

Asset Exposure Score

Tenable.sc+ customers will now have the ability to see and filter on the Asset Exposure Score (AES) in the Host Assets View. The AES is calculated locally and represents the asset's relative exposure as an integer between 0 and 1000. A higher AES indicates higher exposure.

Tenable calculates AES based on the current ACR (Tenable-provided or custom) and the VPRs associated with the asset. This feature will great enhance our Tenable.sc+ customers ability to prioritize risk in their environment.

For more information, see Host Asset Filter Components in the Tenable.sc User Guide.

Host Asset View Filtering

All Tenable.sc customers will now be able to use filtering in the Host Asset View. This new feature will allow customers to filter results based off of the asset information stored in the Host Asset table. Prior to this release, filtering was only possible in the Vulnerability Analysis view.

For more information, see Host Asset Filter Components in the Tenable.sc User Guide.

Citrix Credentials

This feature will allow customers to audit their Citrix ADC / ADM devices for proper configuration to reduce vulnerability of the attack surface.

For more information, see Miscellaneous Credentials in the Tenable.sc User Guide.

Full Scanner Authentication/Communication via API Keys

This feature will allow customers to use secure API keys when importing agent scan data from Nessus or Tenable.io scanners.

For more information, see Nessus Scanners in the Tenable.sc User Guide.

Changed Functionality and Performance Enhancements

Addressed an issue that required an Admin who was changing another users password to input that users password first. This change requires the password of the Admin user prior to changing another users password.
