Anthropic Expands Cyber Verification Program to Three Access Tiers

Anthropic has expanded its Cyber Verification Program, introducing a three-tier access structure that grants verified security researchers and organizations differentiated levels of access to Claude's capabilities for cybersecurity work. The tiered system is designed to enable legitimate offensive security research, vulnerability analysis, and red-teaming while maintaining guardrails against misuse. For developers working in security tooling, penetration testing platforms, or AI-assisted vulnerability research, the expanded program offers a formal pathway to access capabilities that would otherwise be restricted. The verification-based approach also signals Anthropic's effort to build responsible access infrastructure rather than blanket restrictions. This is a notable policy and safety architecture decision with practical implications for the security research community.
