Case Study: Large Global South American Division Bank achieves 78% fraud detection with ThetaRay

Large Global South American Division Bank - Customer Case Study

Large Global South American Division Bank partnered with ThetaRay to improve fraud prevention in its corporate Internet banking operations. The bank was struggling to detect fraudulent transactions in time, relying on legacy rule-based monitoring that missed many cases, generated too many false positives, and often identified fraud only after customers reported it.

ThetaRay deployed its big data and machine learning fraud detection solution to analyze outbound corporate transactions and uncover both known and previously unseen fraud patterns. The combined approach raised the overall fraud detection rate from 44% to 78%, improved detection by 34%, reduced annual fraud losses by an estimated 30%, and lowered the false-positive rate from 30.3% to about 20%, helping the bank stop fraud earlier and improve customer experience.
