OpenAI to acquire Promptfoo

OpenAI plans to acquire Promptfoo, an AI security and testing platform. The technology will help enterprises evaluate AI systems, detect risks such as prompt injection, and improve reliability of AI coworkers.

OpenAI has announced plans to acquire Promptfoo, a platform that helps developers test and secure AI applications. Promptfoo provides tools to evaluate prompts, simulate adversarial attacks, and detect risks such as prompt injection, jailbreak attempts, and data leakage.

The acquisition will integrate Promptfoo’s technology into OpenAI Frontier, a platform designed to build and manage AI coworkers. With automated evaluation and security testing built into development workflows, enterprises will be able to identify risks earlier and maintain oversight of AI systems.

As companies deploy AI agents in real workflows, testing, security, and governance have become critical for reliable and responsible AI deployment.
