PromptBrake stress-tests LLM endpoints with 60+ real attack prompts across 12 security checks. It catches prompt injection, data leaks, tool misuse, policy bypasses, and unsafe output, then returns clear PASS/WARN/FAIL verdicts with evidence and guidance on fixes. Connect any OpenAI-, Claude-, or Gemini-compatible API, keep keys out of storage, and plug scans into CI/CD release gates with exportable reports.
