Key Result40% Less Fraud

The Challenge

The client, a top-tier multinational bank, was struggling with a legacy rule-based fraud detection system that generated an unmanageable volume of false positives. This not only strained their compliance teams, costing millions in operational overhead, but also led to legitimate customer transactions being blocked, damaging client trust and satisfaction. They needed a solution that could adapt to evolving fraud patterns in real-time without compromising user experience.

"Our compliance team was drowning in noise. We needed a signal."

The deployment transformed the bank’s risk management landscape. Within the first quarter, the system identified and prevented a sophisticated botnet attack that would have otherwise gone unnoticed. The reduction in false positives allowed the compliance team to focus on high-value investigations rather than routine clearing.
