Originally reported by Anthropic.
New Cyber Verification Program Launch
Anthropic launches expanded Cyber Verification Program with three access tiers for security professionals to apply for the level of access best suited to their work.
Program Tiers Overview
Defense Access enables security operations, incident response, malware analysis, and vulnerability validation for organizations defending systems they own or maintain.
Red Team Access Details
Red Team Access adds authorized penetration testing and red-teaming to Defense Access, allowing organizations to test systems they are authorized to test without real-time blocks on harmful actions.
Specialized Access Tier
Specialized Access reserves the fewest cyber blocks for organizations authorized to test safety systems impacting people’s lives or markets, such as flight operating systems and power grids.
CyScenarioBench Results
Claude Opus 5.5 blocked 46 of 50 tasks in Defense Access, completed 34 of 50 in Red Team Access, and experienced no blocks in Specialized Access on CyScenarioBench.
Vulnerability Findings
Project Glasswing partners found at least 129,000 verified software vulnerabilities between April and July 2026, with over 33,000 rated critical or high-severity.
Impact on Security Teams
Partners reported using Claude Mythos models increased their vulnerability finding rate by months or years compared to manual methods.
Data Retention Policy
Organizations must retain data for monitoring cyber misuse until Enterprise Frontier Safeguards (EFS) is available later this fall for zero data retention.
Application Process
Interested organizations can apply for CVP access with verification of security controls and proof of required access tier eligibility.
Next Steps
Anthropic will share more about expanding defensive efforts and securing open-source software and critical infrastructure in upcoming weeks.
The one thing
Anthropic expands Cyber Verification Program to three access tiers, enabling security teams to use advanced AI models with reduced cyber blocks while maintaining safety safeguards.
