A Correlation Engine is a system that analyzes large volumes of data from different sources to identify relationships, patterns, and connections between events or variables. It brings seemingly separate pieces of information together and determines whether changes in one data stream are associated with changes in another.
Correlation Engines are commonly used in cybersecurity, fraud detection, IT operations, business intelligence, and IoT environments. For example, a system may correlate login activity, network events, device behavior, and access records to identify a potential security incident. By combining related signals, a Correlation Engine can reduce isolated alerts, uncover hidden patterns, and provide a more complete understanding of complex events.
