PromptBrake is a paid AI security testing platform for live LLM endpoints, AI APIs, and chatbots. It runs repeatable adversarial scans for prompt injection, data leakage, unsafe tool behavior, output-control bypasses, memory exposure, retrieval injection, and launch-readiness failures, then reports PASS, WARN, and FAIL findings with evidence and remediation guidance.
PromptBrake is a paid AI security testing platform for teams that need repeatable adversarial scans of live LLM endpoints, AI APIs, and chatbots, with pricing published for Scout, Pro, and Enterprise plans starting at $49, $99, and $499 per month. It is best for teams that need answer-first, repeatable security evidence before releasing an LLM-powered API or chatbot. Instead of reviewing prompts in isolation, it tests the actual endpoint being shipped and checks whether the running system can leak instructions, expose context, misuse tools, bypass output rules, or regress after prompt, model, retrieval, or tool changes. That endpoint-first model is useful for product teams and security reviewers because the findings reflect the behavior customers or downstream applications would encounter, not just the intended design of a prompt template.
Public PromptBrake pages describe a Full profile with 13 tests and 60+ attack scenarios, hosted scans for fast validation, CI-ready workflows on Pro, and an Enterprise Docker runner for scans inside a customer's own infrastructure. The stated coverage areas include prompt injection, indirect injection, data exposure, unsafe tool or function-call behavior, structured-output escapes, output-control bypasses, memory exposure, retrieval injection, policy confusion, and chatbot launch-readiness failures. Results are framed as PASS, WARN, and FAIL findings with evidence logs and remediation guidance, which makes the product more decision-oriented than a generic prompt experiment or one-off red-team note.

Yes, PromptBrake is good for ai security work. Users particularly appreciate tests the real application endpoint instead of only evaluating a standalone prompt, so results reflect prompts, tools, retrieval, auth path, and response handling together. However, keep in mind requires a working live, dev, or staging api endpoint because promptbrake tests behavior by sending adversarial prompts to the endpoint.
PromptBrake starts at $49/month. Check their pricing page for the most current rates and features included in each plan.
PromptBrake is best for A product team is about to launch a customer-facing chatbot and wants to test for leaked system instructions, missed handoff behavior, invented policies, unsafe promises, and output-rule failures before users interact with it. and An engineering team changed a system prompt, swapped models, or added a new retrieval source and needs repeatable evidence showing whether instruction leaks, context leaks, or policy hallucinations changed before merging.. It's particularly useful for ai security professionals who need prompt injection testing.
