What is Container Scanning?

A container image bundles a base OS layer, system packages and your application. Scanning walks each layer and reports known vulnerabilities, which most often live in the base image rather than anything your team wrote.

The practical output is usually a base-image upgrade recommendation. Tools differ in whether they can tell you which findings come from a layer you control versus one you inherited, a distinction that decides whether the report is actionable.

Top 12 Container Scanning tools

Every tool in the directory documented as supporting Container Scanning, 6 fully, 6 partially, with what its own documentation says.

Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.

What to look for

• Whether findings are attributed to the layer that introduced them
• Registry integration for scanning images already deployed
• Base image upgrade recommendations rather than raw CVE lists
• Whether the scan runs in CI before push, or only on stored images
