OpenAI plans to acquire Promptfoo to enhance AI security testing, risk detection, and compliance capabilities within its Frontier platform for enterprise AI agents.
OpenAI has announced plans to acquire Promptfoo, a move aimed at expanding security testing and evaluation capabilities within its Frontier platform for enterprise AI development. The acquisition will help organizations build, test, and operate AI coworkers more securely as agent-based systems become integrated into real business workflows.
Once the deal is finalized, Promptfoo’s technology will be embedded directly into OpenAI Frontier, the company’s platform designed for building and managing AI-powered coworkers and agents. The integration will provide enterprises with advanced tools to identify vulnerabilities in AI systems during the development phase and address potential risks before deployment.
Strengthening Security for Enterprise AI
As companies increasingly deploy AI agents across operations, the need for reliable evaluation, security testing, and compliance monitoring has become essential. Organizations require structured methods to analyze agent behavior, detect security gaps early, and maintain transparent records for governance and regulatory oversight.
Promptfoo, led by co-founder and CEO Ian Webster along with co-founder Michael D’Angelo, has developed a widely used suite of AI security and testing tools. The platform is trusted by more than 25% of Fortune 500 companies and includes a popular open-source command-line interface (CLI) and library used to evaluate and “red-team” large language model (LLM) applications.
OpenAI confirmed that the open-source Promptfoo project will continue to be supported while new enterprise-grade capabilities are developed within the Frontier ecosystem.
Built-in Security Testing for AI Agents
Following the acquisition, OpenAI plans to integrate several key capabilities into the Frontier platform:
- Native security and safety testing
Automated security testing and red-teaming tools will become built-in features of Frontier, enabling enterprises to detect risks such as prompt injection attacks, jailbreak attempts, data leaks, tool misuse, and policy violations. - Security integrated into development workflows
The platform will allow teams to identify, investigate, and resolve agent risks earlier in the development cycle, making security a fundamental component of enterprise AI system design and deployment. - Oversight, reporting, and compliance support
Integrated reporting and traceability features will help organizations track changes, document testing procedures, and meet growing governance, risk, and compliance requirements related to AI systems.
Advancing Secure AI Development
According to Srinivas Narayanan, Promptfoo brings significant expertise in evaluating and securing AI systems at enterprise scale. Integrating these capabilities into Frontier will help businesses deploy AI solutions that are both reliable and secure.
Promptfoo’s leadership also highlighted the growing importance of AI security as agents become more connected to real-world data and systems.
Ian Webster noted that Promptfoo was founded to give developers practical tools to secure AI applications. By joining OpenAI, the team aims to accelerate innovation in AI safety, governance, and testing capabilities for organizations building production-grade AI systems.
Expanding the Future of AI Coworkers
The acquisition reflects OpenAI’s broader strategy to support enterprises deploying AI coworkers—intelligent agents capable of performing tasks, interacting with data, and assisting across business operations. By integrating advanced evaluation and security frameworks, the Frontier platform is expected to provide organizations with stronger safeguards as AI adoption continues to scale.
With AI agents becoming a core component of modern enterprise infrastructure, enhanced security testing and governance tools will play a critical role in ensuring these systems operate safely, responsibly, and reliably.
