Anthropic expands cyber verification program to enhance cybersecurity capabilities

Anthropic has launched an expanded Cyber Verification Program (CVP), offering three access tiers to security professionals. The program provides access to advanced models like Claude Opus 5.5 and Claude Mythos 5.1, tailored to different cybersecurity tasks. The new tiers include Defense Access for defensive operations, Red Team Access for authorized penetration testing, and Specialized Access for critical infrastructure testing. Organizations applying for Red Team Access will face longer review times, while Defense Access applications are expected to be processed within days. Anthropic also announced a $100 million investment in training 10,000 engineers by 2027. The CVP aims to enhance cybersecurity efforts by enabling faster vulnerability detection. Partners using Claude Mythos models identified over 129,000 vulnerabilities between April and July 2026, with additional findings from open-source scans. Anthropic emphasized the program’s role in securing critical infrastructure and open-source software, with plans to share more updates in the coming weeks.
