gVisor is Google's open-source container runtime sandbox that provides an additional layer of isolation between containerized applications and the host kernel. It implements a user-space application kernel that intercepts system calls, preventing container escapes and limiting the attack surface. Used in Google Cloud Run, GKE Sandbox, and other Google Cloud services. Over 18,000 GitHub stars.
