The challenge

Preventing ATO fraud: The need for real-time detection

A top 20 U.S. bank faced severe financial losses due to ATO fraud. Without a predictive system, the fraud team could only respond after losses occurred, impacting customer satisfaction and trust.

Key challenges

  • Reactive detection failed, allowing losses to grow and customer trust to decline

  • Without prediction, fraud went unchecked—real-time prevention was critical

The solution

Insight-driven analysis and predictive modelling

Data driven fraud prediction

Uncovered patterns in non-monetary data

Defined model targets through data discovery

Generated risk scores using a predictive engine

Machine learning

Analyzed login patterns, device and IP usage

Strengthened detection and mitigation

Enabled proactive fraud prevention
