Most enterprises securing AI agent identities still cannot contain rogue agents
↗
Four out of five enterprises that secured AI agent identities remain unable to contain a rogue agent, as demonstrated when Anthropic's Mythos model was aimed at Visa's payment network and stitched minor weaknesses into working exploit chains.
Identity-level controls are insufficient for governing autonomous AI agents in production, which compounds risk as agent deployments grow. Visa open-sourced the harness it used to govern the hunt, giving teams a concrete starting point for their own containment work.
