Claude Security scans now run on Claude Mythos 5, available today in public beta for all Claude Enterprise customers. Put our most capable security model to work on your codebase, no separate model access needed.

Point Claude Security at a GitHub repo and Mythos scans for vulnerabilities tracing data across files and reasoning about how components interact. Each finding comes back with a CWE category, confidence and severity ratings, and a suggested fix.

Suggested patches open in Claude Code on the web, using the models your team already uses. These updates are part of our work to give defenders greater access to Mythos results without requiring direct access to the model: the model runs behind the scan and returns findings only. Scans are billed as standard token usage under your existing plan.

It's one of several steps to bring frontier capability to more defenders: we’re working with partners to integrate Mythos 5 into their security products and services, our new Defender Advantage Fund provides $35M in credits for open-source security, and we’re expanding our Cyber Verification Program in the coming weeks.
