Anthropic Expands Cyber Verification Program With Three Tiers, Opens Door to Authorized Offensive Work
EricBuess · x · 2026-10-07
Anthropic announced an expanded Cyber Verification Program (CVP), merging Project Glasswing and the original CVP into a unified three-tier access system for vetted security professionals.
- Verified security teams get access to Claude Opus 5.5, Sonnet 5.5, Mythos 5.1, and future models, with safeguards tuned for defensive work.
- New tiers allow authorized offensive use cases like penetration testing and red-teaming.
- Generally available Claude models keep conservative cyber guardrails that block most security tasks; the program aims to cut false positives for defenders.
The move highlights Anthropic's balancing act between limiting malicious misuse and giving defenders the strongest tools.
