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 untrusted or multi-tenant workloads on shared infrastructure should choose gVisor for its userspace kernel isolation; it stops container breakouts that traditional seccomp profiles can't catch because it intercepts syscalls before they reach the host kernel. The 17,900-plus GitHub stars and adoption at scale by Google Cloud customers validate the stability, though runtime overhead of 10-30 percent makes it a poor fit for latency-sensitive applications or shops without the ops bandwidth to tune per-workload syscall allowlists. Skip this if you need file integrity monitoring or network policy management; gVisor solves isolation, not visibility.
