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.
DevSecOps teams building security muscle memory before production incidents happen should use Kubernetes Goat; it's free and deliberately vulnerable, meaning engineers learn by actually breaking real attack chains instead of reading documentation. With 5,400+ GitHub stars and active community contribution, you're getting a battle-tested lab that covers lateral movement, RBAC bypass, and supply chain attacks across multiple Kubernetes versions. Skip this if your team needs instructor-led validation or compliance sign-off; Kubernetes Goat is self-directed learning for hands-on practitioners, not a managed training platform.
