Stop scams before they ever reach your customers.
Subex AI catches up to 95% of malicious traffic while keeping legitimate calls flowing without friction. Nuisance traffic drops, fraud loses its entry point, and every genuine call still gets through. Less spam, more trust, a network customers can answer with confidence.

Overview​

Scam and spam calls undermine customer trust and can trigger regulatory scrutiny. Subex helps CSPs identify suspicious calling behavior and number ranges using ML models and risk scoring, so teams can stop abuse while keeping legitimate traffic flowing.

The Challenge

Scam, spam, and robocalling use automation, spoofing, and social engineering to target subscribers at scale, driving complaints, churn, and overblocking that harms legitimate customers. The CFCA Global Fraud Loss Survey 2025 estimates losses from spoofing and CLI manipulation at about $3.5 billion, while limited context continues to slow analyst response.

Fraudsters use automation, spoofing, and social engineering to target subscribers at scale.

High volumes of nuisance calls increase complaints and churn risk.

Overblocking creates false positives that damage customer experience.

Analysts spend too much time validating suspicious numbers without enough context.
