Anthropic is launching an expanded version of its Cyber Verification Program (CVP) that integrates previous initiatives into a unified offering with three distinct access tiers for qualifying security professionals. The program provides vetted teams with reduced blocking classifiers and access to advanced models, including Claude Opus 5.5, Claude Sonnet 5.5, and Claude Mythos 5.1.
- Defense Access targets defensive work such as incident response and malware analysis for organizations like hospitals and open-source maintainers.
- Red Team Access adds authorized penetration testing capabilities for in-house and government red teams, with no blocks on adversarial tasks against authorized systems.
- Specialized Access offers the fewest cyber blocks for a limited set of verified organizations testing critical infrastructure like power grids and flight operating systems.
- Evaluations using CyScenarioBench showed that Claude Opus 5.5 completed 34 of 50 offensive tasks in the Red Team tier, matching its unsafeguarded performance.
The expansion aims to extend the impact of Project Glasswing, which helped partners uncover at least 129,000 verified software vulnerabilities, by giving a broader range of defenders access to powerful cyber capabilities.
