OpenAI has agreed to acquire Promptfoo, an 11-person AI security startup valued at $86M, to embed automated red-teaming and vulnerability testing into its enterprise platform OpenAI Frontier. Promptfoo already serves 25% of Fortune 500 companies with tools that simulate prompt injections, jailbreaks, and data leaks in AI agents. This deal comes alongside plans to nearly double headcount from 4,500 to 8,000 by end of 2026, signaling that AI agent security is becoming table stakes for enterprise adoption.
