How Promptfoo Red-Teams LLM Applications in CI/CD

Summary
The article describes Promptfoo’s open-source LLM red-teaming workflow: YAML-configured tests use 50+ plugins and delivery strategies, run in CI/CD, and report findings with an LLM judge and framework mappings. It says OpenAI acquired the project in March 2026.
Key points

- The article says its 50+ plugins target issues including prompt injection, jailbreaks, PII leakage, SSRF, SQL injection, and excessive agency.
- Delivery strategies include prompt-injection framing, jailbreak techniques, and multi-turn escalation using Crescendo.
- The described workflow runs generated tests against a target and uses an LLM judge to grade responses.
- The web UI presents prompts, model responses, grader explanations, and mappings to OWASP LLM Top 10, NIST AI RMF, and MITRE ATLAS.
- The article reports that OpenAI acquired Promptfoo on March 9, 2026, and says the project remains MIT licensed and open source.
