Lutril inspects every prompt headed to an LLM, detects PII, secrets, and keys, and redacts them before the model ever sees them, without blocking the work.

- PII & secret detection
- Inline redaction
- Per-model policy

- **Detect** PII, secrets, API keys, and custom patterns.
- **Redact inline** Replace sensitive spans before the model receives them.
- **Per-model policy** Different rules for public models vs. your private endpoints.
- **Immutable audit** Every redaction recorded, nothing stored in the clear.

## A checkpoint on the way to every model.

DLP runs at the same layer that governs your agents, so it applies to chat, copilots, and MCP tool calls alike.

- **Detection that fits your data** Built-in detectors for emails, cards, national IDs, and secrets, plus regex and keyword patterns for your own sensitive fields.
- **Redact, mask, or block** Choose per policy: redact the span, mask to a token the model can reason about, or block the request outright.
- **Works across every model** One policy covers ChatGPT, Claude, Gemini, and your self-hosted models, applied consistently everywhere.
- **Provable compliance** An immutable log of what was detected and redacted gives auditors evidence without exposing the original data.
