FAQ

Frequently Asked Questions

Everything you need to know about how our fraud management solutions work.

How is Subex’s Fraud Management different from traditional fraud detection systems?

Traditional systems react after losses occur. Subex uses real-time scoring, behavioural intelligence, and AI-driven anticipation to surface threats the moment they emerge—across identities, subscriptions, roaming, digital payments, and partner channels. The goal is prevention, not post-incident discovery.

What types of fraud does Subex help telecom operators prevent?

No. Subex is designed to ensure fraud-free journeys without friction. Genuine customers move ahead seamlessly while suspicious activity is flagged or stopped in real time through autonomous, human-supervised decisioning.

Does Subex’s solution integrate with existing telecom systems and data sources?

Yes. Subex works as a modular, interoperable platform that easily connects with billing systems, network feeds, payment gateways, partner systems, and identity sources—enabling unified fraud intelligence without disrupting existing workflows.

How quickly can Subex’s Fraud Management system adapt to new or emerging fraud patterns?

Subex operates as a continuous learning engine. Its AI models evolve with live traffic, behaviour shifts, and new threat signatures—allowing operators to anticipate risks early and deploy new controls without waiting for rule updates or manual interventions.
