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.
Security teams building internal red team capacity or running incident response drills will get the most from Simulator because it lets you spin up deliberately broken Kubernetes clusters in AWS without needing to maintain custom vulnerable infrastructure. The free pricing and 981 GitHub stars indicate active adoption among practitioners who value hands-on cluster attack scenarios over theoretical exercises. Skip this if your team needs a polished SaaS training platform with guided curricula and progress tracking; Simulator is a raw sandbox, not a structured learning program.
