What is Network Detection and Response in Cybersecurity?
A security technology that monitors raw network traffic using behavioral analytics, machine learning, and threat intelligence to detect threats that bypass perimeter defenses. NDR captures and analyzes network metadata and full packets to identify lateral movement, command-and-control communication, and data exfiltration.
Why Network Detection and Response Matters for Your Cybersecurity Career
NDR fills a visibility gap that endpoint-only cybersecurity tools miss, especially for unmanaged devices and IoT. SOC analysts use NDR to detect threats moving between network segments. Security engineers deploy NDR sensors at critical network junctions. Threat hunters query NDR data to find adversary activity that evaded SIEM detection rules.
