OpenAI is acquiring Promptfoo, an AI security platform that helps enterprises identify and remediate vulnerabilities in AI systems during development.

Promptfoo ModelAudit scans 42+ ML model formats for unsafe loading behaviors, known CVEs, and suspicious artifacts. Now MIT-licensed and open source.

We built a GitHub Action that scans pull requests for LLM-specific vulnerabilities. Learn why traditional security tools miss these issues and how we trace data flows to find prompt injection risks.
