Fraud Guard

Stop SMS pumping
before it burns your budget

Artificially inflated traffic can drain a messaging budget in minutes. Fraud Guard analyzes every message you send in real time, scores it for risk, and blocks fraudulent traffic before it ever reaches a carrier.

Your traffic, under guard

A live decision engine sits between your API call and the carrier — watching, scoring, and blocking in milliseconds.

Protection that works while you sleep

Fraud Guard sits inline on every send — no SDK, no extra API call, no integration work.

01

Analyze

Every outbound message is scored in real time against velocity signals, destination risk, and traffic patterns learned across the Chaari network.

02

Decide

Suspicious traffic is blocked or flagged according to your thresholds. Legitimate messages pass through with no added latency you can notice.

03

Review

Every decision is logged with full context in your dashboard, so you can audit what was blocked, tune rules, and whitelist trusted destinations.

Everything you need to shut fraud down

Granular controls when you want them, safe defaults when you don't.

Velocity controls

Active

Cap messages per destination, per prefix, or per time window. Sudden bursts to number ranges you've never messaged get stopped cold.

Destination risk scoring

Active

Number ranges known for pumping schemes are flagged using intelligence aggregated across the whole Chaari network — you benefit from every attack we've ever seen.

Custom rules & allowlists

Active

Define your own blocking rules per country, prefix, or sender. Whitelist the destinations your business depends on so they are never interrupted.

Real-time alerts

Active

Get notified the moment anomalous traffic is detected, with a one-click kill switch to pause a route, a sender, or an entire account.

Send at scale without babysitting your traffic

Fraud Guard is on by default for every Chaari account. Create one and your very first message is already protected.

Every Chaari account ships with the full toolkit. No add-ons, no enterprise gate.
