# Tripwire

> Local prompt-injection inspection with reproducible evidence.

Tripwire Inspect is a free Chrome developer preview. It scans user-chosen content locally, reports known heuristic signals, and makes no network requests. A clean result is not a guarantee of safety.

## Paid team review

Tripwire offers a founder-delivered, fixed-scope agent injection-surface review for EUR 2,500. It maps up to three ingestion paths and action sinks, runs documented scenarios against an agreed staging workflow, and delivers reproducible findings plus a prioritized control plan. Scope and commercial terms are agreed in writing before work starts. It is not a certification, penetration test, or guarantee that every injection path will be found.
