Cisco is adding Claude Mythos to controlled AI red-team testing
Cisco is adding Claude Mythos to AI Defense’s adaptive red-teaming framework for authorized attack simulations against AI applications and agents.

AT A GLANCE
Key points
- Claude Mythos will generate contextual multi-step test paths
- Testing is limited to registered and authorized targets
- Select-enterprise availability is described as coming soon
What is changing?
Cisco announced that Anthropic’s Claude Mythos model will be added to AI Defense’s adaptive red-teaming system. The integration is intended to generate contextual, multi-step attack paths and expose weaknesses in AI applications and agents before production.
The company is limiting access through a structured interface rather than open-ended prompting. Tests will run only against enterprise-registered and authorized targets; every engagement will be tied to a named operator, use fixed objectives and time limits, remain revocable, and leave an audit trail.
Claude Mythos-powered adaptive red teaming is coming soon for select enterprises. Cisco’s security and performance claims are provider statements and still need evaluation based on real coverage, false-positive rates, and the effectiveness of stop controls.
