Explanation
One of the key purposes of leveraging visibility & analytics capabilities in a ZTA is to continually evaluate user behavior against a baseline to identify unusual actions. This helps to detect and respond to potential threats, anomalies, and deviations from the normal patterns of user activity. Visibility & analytics capabilities also enable the collection and analysis of telemetry data across all the core pillars of ZTA, such as user, device, network, application, and data, and provide insights for policy enforcement and improvement.
