Your messaging API bill shouldn't be an attack surface.
A fraud ring can burn hundreds of dollars in SMS costs before anyone notices — Twilio's own Fraud Guard didn't step in until 2,500 fraudulent messages had already gone out on one real account, about $800 lost in a few hours. B2D Core's gateway sits in front of Twilio and stops that traffic before it's billed, not after.

We won't tell you this stops 100% of fraud.
Most vendors will. We'd rather tell you exactly what this gateway covers — rate limits, spend budgets, geography, and signature validation, enforced before Twilio bills you for the request — and let you decide if that's the layer you need. It isn't a complete answer to fraud. It's an honest one.
Messaging Antifraud Gateway
Open source. Self-hosted — it runs inside your infrastructure, never ours, and never sends message content anywhere. Drop it in front of your Twilio integration and it blocks abusive traffic in just a few milliseconds, before the request ever reaches Twilio.
