microvm security

MicroVM security on WindowsForum.com covers the use of lightweight virtual machines as isolation boundaries for untrusted or autonomous workloads. The tagged discussion looks at Docker Cloud Sandboxes, launched in September 2026, which run AI coding agents such as Claude Code, Codex and Copilot inside hosted microVMs billed by the second. The key security argument is that a container packages an application, while an agent probing the kernel needs a boundary below it. A revised Kit specification also turns an agent's network, credential and volume permissions into an ordinary OCI image, tying microVM isolation to practical permission control.
