Chainguard Harness hunts live-app vulns with Claude Mythos 5.1 via Claude Marketplace
Chainguard opened a beta waitlist for Harness: it rebuilds your app from source in an isolated, no-egress microVM, lets Claude Mythos 5.1 probe the live instance for exploitable vulns, and ships only findings that replay plus fixes that stop them—each reviewed by a Chainguard engineer. Buy it through Anthropic’s Claude Marketplace and apply existing Anthropic commitments.
