Tenable Cloud Security now supports container image and container registry scans for detecting vulnerabilities and enforcing policies. You can scan container images securely without sending the images outside your organization's network.

• Scan images in registries: Continuously monitor and scan registries to detect new vulnerabilities that may have been introduced over time.

• Integrate with CI/CD pipelines: Incorporate security scans, policy enforcement, and compliance seamlessly into pipeline stages by integrating with popular CI/CD tools.

• Scan local images: The container security feature enables developers to identify and address potential vulnerabilities and security issues early in the development lifecycle by scanning local images.

• Create comprehensive container security policies: Allow security teams to write complex policies leveraging the Tenable Cloud Security no-code Rego policy editor. The container security feature empowers security teams to create complex Rego-based policies effortlessly using our built-in no-code policy editor without the need for extensive coding knowledge. These policies can then be enforced in the DevOps pipelines to provide enhanced security guardrails. For more information, see Create a Custom Policy.

• Unified and comprehensive view of cloud security: With the addition of container security, you can now have an all-encompassing perspective on vulnerabilities within your containerized environments.

Scan images and registry using Tenable Cloud Security CLI

Scan any OCI-compliant Docker image using the Tenable Cloud Security CLI. To run container image and registry scans, download and install Tenable Cloud Security CLI v2.2.0. After your scan completes, you can view the scan results in the Legacy Tenable Cloud Security Console. Legacy Tenable Cloud Security also provides key insights about the container scans on the Containers and Vulnerabilities dashboards.

For more information about container security, see Container Security with Tenable Cloud Security.
