Anthropic opens a verification program for cybersecurity
Cyber Verification Program provides tiered access for defense and authorized security testing, rather than unrestricted access for everyone.
What is changing?
Anthropic’s October 6 announcement divides cybersecurity access into three tiers. Defense Access supports defensive work; Red Team Access serves organizations conducting authorized tests; Specialized Access is limited to verified critical organizations.
Eligible users can access models including Opus 5.5, Sonnet 5.5 and Mythos 5.1. Red Team access is rolling out gradually, with Defense Access available in the interim. Additional verification, terms and data retention requirements apply; safeguards against physical harm remain.
AI Radar perspective: For teams building enterprise assistants, access is being differentiated by task and authorization. This does not remove security restrictions for general users.
