OpenAI's cyber leadership explains why every organization needs its own 'defense factory' to turn AI-discovered vulnerabilities into verified fixes before attackers exploit them. The session covers the defenders' window, ecosystem responsibilities, GPT-6 Astra's cyber capabilities and safeguards, the Daybreak Red and Blue tiers, Codex Security workflows and CLI scaling, and OpenAI's internal continuous-defense architecture and results.
