ClaudeAnthropic launched an expanded Cyber Verification Program (CVP), which makes advanced cyber capabilities and reduced blocking classifiers available to qualifying security professionals.
- It now has three access tiers.
- Defense Access covers defensive work such as security operations, incident response, malware reverse-engineering and vulnerability validation; Anthropic expects many defensive organisations to qualify and aims to respond within a few days.
- Red Team Access adds authorised penetration testing and red-teaming for organisations only, with reviews expected to take a few weeks.
- Specialized Access, with the fewest cyber blocks, is reserved for a limited set of verified organisations that test safety-critical systems, reviewed in depth with the US government.
- Each tier includes Anthropic's most capable models, including Claude Opus 5.5, Claude Sonnet 5.5 and Claude Mythos 5.1.
- Project Glasswing folds into Specialized Access, and existing members transition without reapproval for current models.
- Generally available models keep their conservative cyber safeguards.
- Who can use it
- Qualifying security professionals and organisations who apply. Defense Access includes individual researchers with a track record; Red Team Access is for organisations only; Specialized Access is a limited set of verified organisations.
- When
- Announced October 6, 2026; applications open the same day. Anthropic aims to answer Defense Access applications within a few days and Red Team Access within a few weeks.
