This post details EVO Banco's implementation of Confluent Cloud for real-time fraud detection, processing over 500,000 daily transactions. It explains how Confluent Cloud handles real-time transaction data from various sources (ATMs, online payments, mobile banking) and feeds it into an ML model trained with historical data processed by Apache Spark. The system generates real-time alerts via email, SMS, or mobile push notifications. The post quantifies the impact, stating an average of 500 fraudulent transactions blocked daily and a 99% reduction in weekly fraud losses. It also highlights the aggregation of diverse data sources (transaction, customer, device, authentication logs) and the provision of contextual, high-fidelity data to AI/ML models.
