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.
ICS security teams building internal training programs need GRFICSv2 because it ships as five pre-configured VirtualBox VMs that let you stand up a realistic industrial control network in hours instead of months of custom lab work. The free pricing and 597 GitHub stars signal actual adoption among practitioners who've validated the simulation fidelity. Skip this if your organization needs a managed platform with instructor dashboards and automated scoring; GRFICSv2 is a DIY framework that demands hands-on lab administration.
