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.
Teams running multi-tenant Docker environments who need to validate that inter-container isolation actually works should test Docker Layer 2 ICC Bug immediately; it exposes a real bypass in ICC enforcement that raw socket access creates, one that most container security tools and network policies silently miss. The 66 GitHub stars reflect active adoption among practitioners who've caught this in production, and the vulnerability remains unpatched in older Docker versions still in heavy use. Skip this if you're already using eBPF-based runtime monitoring or running only single-tenant clusters where container-to-container trust assumptions hold; this tool does one thing and doesn't prevent the vulnerability, only detects that it exists.
