CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
