The acquisition highlights OpenAI’s broader strategy to improve enterprise AI safety, risk management, and secure deployment, as businesses rapidly scale the use of autonomous AI agents across operations.
OpenAI has announced plans to acquire Promptfoo to enhance security testing and evaluation capabilities for enterprise AI systems. The acquisition aims to strengthen safeguards for autonomous AI agents as businesses increasingly integrate generative AI into real-world workflows.
Promptfoo specializes in tools that help developers identify vulnerabilities in AI systems during the development stage. Its platform detects risks such as prompt injection attacks, data leakage, and misuse of connected enterprise tools, allowing organizations to secure large language model (LLM) applications before deployment.
Following the acquisition, Promptfoo’s technology will be integrated into OpenAI Frontier, a platform designed to help companies build and manage AI-powered “AI coworkers” for enterprise operations. Financial terms of the deal were not disclosed, and the transaction is subject to standard closing conditions.
According to OpenAI, Promptfoo’s automated security testing and red-teaming capabilities will become a native part of the Frontier platform. This integration will allow enterprises to proactively identify and mitigate security risks before AI agents interact with business systems, internal data, or operational workflows.
Srinivas Narayanan, CTO of B2B Applications at OpenAI, said Promptfoo brings strong engineering expertise in evaluating, testing, and securing AI systems at enterprise scale. He noted that integrating these capabilities into the Frontier platform will help businesses deploy more reliable and secure AI applications.
As organizations increasingly connect AI tools to sensitive enterprise data and internal software systems, concerns around AI governance, compliance, and oversight are becoming critical. OpenAI said the Frontier platform will include advanced reporting and traceability features, enabling companies to document testing processes, track system changes, and meet regulatory requirements.
Ian Webster, co-founder and CEO of Promptfoo, said the company was founded to give developers practical tools to secure AI systems. As AI agents become more deeply integrated into enterprise data environments and business processes, ensuring their reliability and security has become increasingly complex and essential.
Promptfoo’s platform is already widely adopted by developers and enterprises. The company provides an open-source command-line interface and evaluation library that helps teams test, benchmark, and stress-test AI applications. According to the company, its tools are currently used by more than 25% of Fortune 500 companies to evaluate AI system performance and security.
