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 training ICS defenders on a budget should use GRFICS because it's free and lets operators practice real attack chains in a visual 3D environment instead of reading documentation or staring at command lines. The framework runs on Unity and requires no licensing, making it practical for manufacturing facilities and utilities that can't justify expensive simulators for tabletop exercises. Skip this if your team needs NIST Govern function support or compliance reporting; GRFICS is pure hands-on practice, not an audit tool.
