CST VerdictBased on our analysis of available product data, here is our conclusion:
Security engineers who need to understand how containers actually work before deploying detection tools should start with Container Internals Lab. The structured labs walk you through Linux namespaces, cgroups, and syscall behavior hands-on, which directly translates to writing better runtime policies and knowing what your scanner should catch. Skip this if your team has no appetite for learning; it's educational material, not a scanning or enforcement product, and the 62 GitHub stars signal a niche audience that values depth over market adoption.
DevOps teams running Docker in CI/CD pipelines need Drydock because it audits container images against CIS benchmarks before they hit production, catching misconfigurations that scanners miss. The tool ships with customizable profiles and JSON output, so you can integrate it directly into your build process without manual remediation work. Skip this if your organization requires a graphical dashboard or runtime monitoring; Drydock is audit-focused and doesn't track container behavior after deployment.
