For more information, see Policies in the Tenable Enclave Security Tenable Container Security user guide.

Detection Expansion

The Tenable Container Security scanner has received a significant capability enhancement, improving coverage breadth and vulnerability detection. This includes an extended array of language libraries (for example, Go, Java, and PHP) and the detection of unpatched vulnerabilities in container images

Tenable Security Center 6.6.x Integration

Tenable Enclave Security 1.5 incorporates the latest version of Tenable Security Center, providing parallel capabilities between Tenable Security Center on-prem and Tenable Security Center in Tenable Enclave Security. This ensures users benefit from the most up-to-date Tenable Security Center features and improvements listed in Tenable Security Center 6.6.0 Release Notes (2025-05-06).

Changed Import Behavior for IP Repositories with DHCP Tracking Disabled

In Tenable Security Center 6.6.5, when DHCP tracking is disabled and a scan import includes a new IP address, Tenable Security Center now treats the new IP as a separate asset and no longer removes attribute data — such as MAC address, DNS name, and NetBIOS name — from any existing asset record at a different IP address. Tenable Security Center continues to match assets exclusively by IP address when DHCP tracking is disabled.

For more information, see Active Scan Settings in the Tenable Security Center User Guide.

  • Fixed an issue with Search failing against Layers using the cmd criteria.

  • Fixed an issue with Tenable Container Security agent failing to perform scans under a specific configuration.

  • Improved performance when generating reports against Tenable Container Security data.
