"When Ian Webster was leading the LLM engineering team at Discord, shipping AI products to 200 million users, he noticed something the security industry had not yet caught up with: the tools his team relied on to keep those products safe were built for a different era. Traditional vulnerability scanners could not reason about prompt injection. Static analysis had nothing to say about a model that promised a user something it had no authority to deliver."
"The deal, terms of which were not disclosed, will see Promptfoo's technology integrated into OpenAI Frontier, the enterprise agent management platform that OpenAI launched in early February. In a post on X, OpenAI said the acquisition would strengthen agentic security testing and evaluation capabilities within Frontier, and pledged that Promptfoo would remain open source under its current licence, with continued support for existing customers."
OpenAI has acquired Promptfoo, a security testing platform used by over 125,000 developers and 30+ Fortune 500 companies. Founded by Ian Webster and Michael D'Angelo, Promptfoo addresses a critical gap in AI application security that traditional vulnerability scanners cannot handle, such as prompt injection attacks and model reliability issues. The acquisition represents OpenAI's most direct move into AI application security. Promptfoo's technology will be integrated into OpenAI Frontier, the enterprise agent management platform launched in February. OpenAI committed to maintaining Promptfoo as open source under its current license while providing continued support for existing customers. Promptfoo raised $5 million in seed funding from Andreessen Horowitz in 2024.
