Automated LLM Red Teaming in Production: Comparing Garak, PyRIT, and Promptfoo
Static penetration testing and manual prompt probing cannot secure non-deterministic language models or agentic systems. Manual testing provides anecdotal security at best: the attack surface of large language models spans thousands of adversarial permutations, multi-turn conversational steering, payload encoding, and indirect prompt injections introduced through external retrieval. To systematically identify failure modes before deployment, engineering teams rely on automated red teaming frame
