Carrier-grade fraud protection

Real-Time Detection

Analyze every call event in real time — no batch jobs, no next-day alerts. Fraud is stopped as it happens.

Anomaly Scoring

Machine-learning anomaly scores on every call session. Configurable thresholds for auto-block vs. alert.

Instant Alerts

Get notified via webhook, email, or SMS the moment suspicious patterns are detected on any account.

Auto-Block Rules

Define rules to automatically block destination prefixes, caller IDs, or accounts when thresholds are breached.

Destination Risk Scoring

Built-in risk scores for high-fraud destination prefixes. Automatically warn or block premium-rate and known-fraud numbers.

Fraud Analytics Dashboard

Track blocked calls, fraud attempts by type, cost savings, and risk trends over time from one dashboard.

— Threats We Stop

Every fraud vector covered

International Revenue Share Fraud (IRSF)

Calls to premium-rate numbers generate fraudulent revenue. We detect unusual volumes to high-cost prefixes in real time.

Toll Fraud

Unauthorized call generation using compromised credentials. Behavior-based anomaly detection catches it in seconds.

TDoS Attacks

Telephony Denial of Service floods your systems with calls. Rate limiting and pattern detection stop floods before they impact service.

SPIT (Spam over IP Telephony)

Automated robocalling campaigns. Caller ID pattern analysis and call volume profiling identify and block bulk SPIT sources.
