Sonar by Rippleshot is an AI-based fraud detection and prevention tool designed for financial institutions. It uses machine learning and predictive analytics to identify compromised cards, detect data breaches, and provide insights into card portfolio health. Sonar analyzes each card in an issuer's portfolio nightly, assessing exposure from compromised merchants to generate fraud forecast scores for the next 90 days. The system detects card compromises and data breaches faster than traditional network alerts, enabling proactive card management and strategic reissuance.
