FAQ
Most scans finish in 3 to 8 minutes depending on endpoint latency and test profile.
No. PromptBrake is designed for engineering teams that need actionable findings, not a custom offensive-security workflow.
Scout Trial and Pro Trial both include free scans. Scout is the lighter starting point, while Pro includes more scans and deeper workflow support.
Yes. Pro trial and paid Pro accounts can generate CI API keys and enforce release gates in GitHub Actions, GitLab CI, or other pipelines.
A FAIL means PromptBrake detected risky behavior like data leakage or unauthorized tool execution. You get evidence so you can fix it and rerun before deployment.
It tests whether the API endpoints behind AI features can be manipulated through prompt injection, data exfiltration, tool abuse, and output bypasses before release.
