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.
Academic security teams and ICS researchers with limited budgets should use LICSTER to build hands-on lab environments without licensing overhead; the free testbed lets you model real industrial protocols and attack chains at a fraction of what commercial simulators cost. LICSTER prioritizes fidelity in Identify and Detect functions, letting you test detection logic against authentic MODBUS and DNP3 traffic patterns. Skip it if you need operational production monitoring or vendor support; this is a sandbox for learning, not a runtime security tool.
