Claude Mythos 5.2 in Devin Security
On November 11, 2026, Claude Mythos 5.2 became available in Devin Security for eligible enterprise customers. Devin runs managed scans with frontier cyber models, so a security team does not need separate access to the models. Cognition is giving $100M+ in credits to enterprises to find and fix vulnerabilities with Claude Mythos 5.2, and says it is committing hundreds of millions of dollars in Devin credits, including free scans with frontier cyber models for current and future enterprise customers. Eligibility criteria and conditions apply. On Cognition's internal cyber benchmark, Mythos 5.2 scored 73.5, up from 56.9 for Mythos 5.1 and above Claude Opus 5.5's 32.7. The benchmark covers 25 repositories, including C, Python, Go, PHP, and TypeScript codebases built on Django, Flask, Laravel, and Next.js, pinned to commits where 1,781 publicly reported vulnerabilities are still present. The score is an F2 on a 0-100 scale, weighted toward recall, from the mean of three runs on every repository.
