Anthropic expands Cyber Verification Program into three tiered access levels
AIAnthropic is launching an expanded Cyber Verification Program with three access tiers for qualifying security professionals, giving each tier different cyber capabilities and reduced blocking classifiers. On CyScenarioBench, Claude Opus 5.5 was blocked on 46 of 50 trials in the Defense Access tier, while the Red Team Access tier had no blocks and completed 34 of 50 tasks. Existing Project Glasswing members will move to the Specialized Access tier, and data retention is required for enrolled organizations.
Why it matters: The program lays out three verified access tiers with different cyber blocks, and its CyScenarioBench figures show how safeguards change what defenders can do.
