OpenAI to buy Promptfoo for enterprise agent security
OpenAI just announced plans to acquire AI security platform Promptfoo, trusted by over 25% of Fortune 500 companies. Once finalized, Promptfoo’s automated red-teaming, prompt injection detection, and jailbreak prevention tools will be baked directly into OpenAI Frontier, while its open-source CLI remains active. Why it matters: As AI coworkers gain access to sensitive enterprise workflows, proactive agent security is rapidly shifting from an optional plugin to essential platform infrastructure.
