OpenAI has announced plans to acquire Promptfoo, an AI security platform focused on helping enterprises identify and address vulnerabilities in AI systems during development. Once the acquisition is finalized, Promptfoo’s technology will be integrated directly into OpenAI Frontier, the company’s platform for building and operating AI coworkers.
As organizations increasingly use AI agents in their operational workflows, it is becoming increasingly important to have evaluation, security, and compliance tools in place. It is also becoming increasingly important for organizations to have ways to evaluate their AI agents, detect vulnerabilities in their agents, and maintain transparent records to ensure proper governance and oversight of their agents.
Promptfoo, an AI evaluation and security tools suite developed by the Promptfoo team, consisting of Ian Webster and Michael D’Angelo, is used by more than 25 percent of Fortune 500 companies. It also includes an open-source command-line interface and library, widely used for evaluating and red teaming large language model applications. Both companies are planning to continue the development of the open-source tool after the acquisition, along with the development of the enterprise product in the Frontier ecosystem.
“Promptfoo brings deep engineering expertise in evaluating, securing, and testing AI systems at enterprise scale. Their work helps businesses deploy secure and reliable AI applications, and we’re excited to bring these capabilities directly into Frontier,” said Srinivas Narayanan, CTO of B2B Applications, OpenAI.

Strengthening Security and Governance for Enterprise AI Agents
The integration of Promptfoo’s capabilities into OpenAI Frontier will expand the platform’s enterprise security and evaluation features. Several key capabilities are expected to be introduced or enhanced:
Security and safety testing built into the platform:
Automated security testing and red-teaming will become native features within Frontier, helping organizations detect and mitigate risks such as prompt injections, jailbreak attempts, data leaks, tool misuse and policy violations by AI agents.
Security and evaluation integrated into development workflows:
Frontier will incorporate security and risk analysis directly into development pipelines, enabling teams to identify, investigate and resolve potential issues earlier in the AI development lifecycle.
Oversight and accountability:
Integrated reporting, traceability and audit capabilities will allow organizations to track testing activity, monitor system changes and meet evolving governance, risk and compliance requirements associated with enterprise AI deployments.
“We started Promptfoo because developers needed a practical way to secure AI systems. As AI agents become more connected to real data and systems, securing and validating them is more challenging and important than ever. Joining OpenAI lets us accelerate this work, bringing stronger security, safety, and governance capabilities to the teams building real-world AI systems,” said Ian Webster, Co-founder and CEO, Promptfoo.
