Anthropic Cyber Verification access tiers

Anthropic announced an expanded Cyber Verification Program on October 6. It combines its earlier verified cyber access and Project Glasswing work into Defense, Red Team and Specialized Access tiers. Qualifying applicants can request access to capabilities in Claude Opus 5.5, Sonnet 5.5 and Mythos 5.1 with different cyber safeguards according to their work. The company says Defense Access can include individual researchers with a record of reported vulnerabilities, while Red Team Access is limited to organizations testing systems they are authorized to assess. Specialized Access is reserved for a small set of verified organizations working on high-risk systems. General public access to the models’ cyber capabilities has not been opened by this announcement.
