Cloudflare is an internet-infrastructure and security company and a partner in Project Glasswing. Its inclusion among the ~50 Glasswing partners places it in the coalition’s extended membership beyond the twelve named launch partners.

Glasswing Result (One Month In)

Per Anthropic’s one-month update and Cloudflare’s own Cyber Frontier Models post, Cloudflare used Claude Mythos Preview to find 2,000 bugs across its critical-path systems, of which 400 were high- or critical-severity, at a false-positive rate the Cloudflare team considers better than human testers.

FP rate “better than human testers”. Cloudflare’s false-positive-rate claim is one of the clearest first-party defender statements that frontier-AI vulnerability discovery has crossed the precision threshold where it competes with skilled human review — not just on recall but on precision. It corroborates the harness-over-model precision argument from a deploying enterprise rather than a model vendor.
