Fraud Detection and Prevention

Fraud Detection and Prevention is a cybersecurity discipline that applies computational methods to identify and stop illicit activities, primarily in financial and online systems. It involves the real-time analysis of vast amounts of data, such as user transactions and behaviors, to spot anomalies and patterns indicative of fraud. By utilizing techniques ranging from predefined rule-based systems to sophisticated machine learning models that learn from historical data, organizations can proactively block threats, minimize losses, and protect the integrity of their services and customer information.
