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 teams or training junior analysts on a budget should use Labs-Pentest for hands-on penetration testing practice without licensing costs. Its 272 GitHub stars reflect active maintenance and a collection of real CTF challenges that beat sanitized vendor labs for teaching actual exploitation technique. Skip this if your goal is measuring individual competency through formal assessments; Labs-Pentest is a free practice ground, not a credentialing platform.
