The primary function of behavioral analytics in cybersecurity is to analyze user behavior and identify anomalies that may indicate security threats. By monitoring patterns such as login locations, access times, and interaction with systems, behavioral analytics can detect unusual activities that deviate from established norms. This proactive approach enables organizations to respond swiftly to potential breaches or fraud, thus enhancing their overall security posture. Furthermore, it aids in the refinement of access controls and security policies, ensuring better protection against evolving cyber threats.
