Anthropic moved Claude Security scans onto Claude Mythos 5, now in public beta for all Claude Enterprise customers. Point it at a GitHub repo and Mythos traces data across files, returning CWE, confidence, severity, and a suggested fix that opens in Claude Code on the web.

Key Takeaways

  • ✓No separate Mythos 5 access required: the model runs behind the scan and bills as standard plan tokens
  • ✓Findings include CWE, confidence, and severity; suggested patches open in Claude Code on the web
  • ✓Paired with a $35M Defender Advantage Fund for open-source security and an expanded Cyber Verification Program
