PG PromptGuard Scan

jailbreak detection API

Jailbreak Detection API for AI Products

A jailbreak detection API helps product teams spot when users or untrusted context try to bypass safety, policy, or tool boundaries in an LLM app.

Run demo scan

Where it fits

  • Screening prompt traffic before it reaches a high-privilege model or agent tool.
  • Adding security telemetry to moderation, support, coding, or research assistants.
  • Testing whether a known jailbreak family still works after prompt or model changes.

Operational steps

  • Send the candidate prompt, recent turns, policy name, and app surface to the detection endpoint.
  • Use the response severity to block, review, log, or downscope the request.
  • Replay known jailbreak families in staging before release.
  • Feed confirmed misses back into a custom test pack for future regression scans.

Common risks

  • A single-turn classifier misses gradual roleplay or authority-shifting attacks.
  • The app detects toxic language but not attempts to override system instructions.
  • Detection logs contain sensitive user text without minimization controls.

How PromptGuard Scan fits the workflow

PromptGuard Scan combines a maintained jailbreak library with scan reports and API responses that fit product telemetry, CI checks, and security review workflows.
