AI Red Teaming Tools Compared: promptfoo vs DeepEval vs Garak and 3 More
With the EU AI Act's adversarial robustness mandate now enforceable, OWASP ASI 2026 targeting agentic apps, and OpenAI's Astra paused, red teaming is mandatory. This review compares six tools-promptfoo, DeepEval, Garak, NeMo Guardrails, PyRIT, and Inspect AI-drawing the line between red teaming, evaluation, and guardrails, with selection guidance by need. Representative comparison, not a hands-on benchmark; star counts verified via GitHub API.
