Anthropic gives more security teams access to Claude with fewer safety restrictions

Anthropic is opening its Cyber Verification Program to a much wider pool of security professionals. The program gives vetted organizations and individual researchers access to Claude's most powerful AI models with reduced safety filters for vulnerability research, malware analysis, incident response, and penetration testing. The publicly available Claude models block most of that kind of work because the same capabilities could also help attackers. Basic tasks like code review or patching known flaws are still possible without special access.

The CVP splits access into three tiers. "Defense Access" is open to corporate security teams, government agencies, universities, critical infrastructure operators, open-source developers, and individual researchers. "Red Team Access" allows authorized attack simulations and is limited to organizations only. "Specialized Access" is reserved for testing systems like flight controls, power grids, or banking infrastructure. For this tier, Anthropic vets every applicant together with the US government.

Partners in the predecessor program, Project Glasswing, found at least 129,000 confirmed vulnerabilities between April and July 2026, according to Anthropic. More than 33,000 were classified as high-severity or critical. Those numbers come from surveys of a subset of partners, and Anthropic says the real-world impact is at least five times higher. Several partners reported that the AI sped up their work by months or even years. Ad Ad
