Messaging Antifraud Gateway

Stop abusive messaging traffic before it costs you.

Status: pre-release. The gateway is functional and under active development; the source repository is not public yet.

What this does — and does not — guarantee

This gateway is one layer, not a complete guarantee against fraud. It runs in front of your messaging provider and blocks traffic based on rate limits, spend budgets, geography, and request-signature validation — before you pay for it. It does not claim to catch every fraudulent message; we'd rather be specific about what it covers than promise '100% protection' the way some vendors do.

How it works

Self-hosted: it runs inside your own infrastructure, in front of your messaging API, and never sends raw message content anywhere — only aggregated decisions and counters, to your own control plane. Open source, so you can read exactly what it does before you trust it with production traffic.
