Dockerscan is a free container security tool. Docker's Actuary is a free container security tool. Compare features, ratings, integrations, and community reviews side by side to find the best container security fit for your security stack.
CST VerdictBased on our analysis of available product data, here is our conclusion:
Development teams running Docker in lab or early-stage environments should start with Dockerscan because it's free and requires no setup to scan your images and running containers for known vulnerabilities. The 1,531 GitHub stars indicate solid adoption among engineers who want quick local feedback before pushing to registry, not a replacement for runtime security in production. Skip this if you need network segmentation analysis or compliance reporting; Dockerscan does vulnerability scanning well and stops there.
Teams building container CI/CD pipelines need Docker's Actuary because it catches misconfigured deployments before they reach production, and it does this for free without vendor lock-in. The tool audits against 81 community-maintained checks covering image layer scanning, runtime permissions, and secrets exposure, catching the kinds of oversights that slip past code review. Skip it if your threat model prioritizes runtime behavior detection or if you need enforcement controls that block bad deployments; Actuary is assessment-only, not prevention.
