Network Detection and Response (NDR)

Network Detection and Response (NDR) is the continuous monitoring and analysis of network traffic in order to detect suspicious activities, attacks and unusual behavior. NDR solutions look at communication patterns between endpoints, servers, cloud services and identities and thereby provide insights that individual protection systems often do not capture.

Unlike classic signature-based controls, NDR frequently works with behavioral analyses, statistical models and artificial intelligence. This also makes unknown attack patterns, lateral movement, command-and-control communication or data exfiltration visible. What is decisive is not just a single connection, but its context within the entire environment.

NDR complements EDR, which looks at endpoints, with the network perspective and provides telemetry that can flow into XDR architectures and SIEM systems. The advantage: attackers can hardly hide network traffic completely, even if agents on endpoints have been deactivated. NDR is thus a core element of modern security architectures – automated attack detection at the network level shortens the time to detect and contain attacks.
