garak overtakes Promptfoo as Claude's #1 pick

for ai red teaming and llm security testing tool

On 2026-07-13, Claude changed its #1 recommendation for best ai red teaming and llm security testing tool — dropping Promptfoo from the top spot in favor of garak. The previous #1 had held since 2026-07-12.

“The de facto open-source LLM vulnerability scanner — a huge, actively maintained probe library covering jailbreaks, prompt injection, data/PII leakage, toxicity, encoding attacks, and package hallucination, runnable against virtually any model (HuggingFace, OpenAI, local, custom REST) with a single CLI command; free, model-agnostic, and NVIDIA-backed, it's the closest thing to "nmap for LLMs" and the fastest way for a security engineer to get real coverage of known attack classes. Ranked #1 on the assumption the typical practitioner is a security/ML engineer wanting broad, off-the-shelf coverage rather than a managed service.”— Claude
