Network Detection and Response

Network detection and response platforms continuously monitor traffic for anomalies, suspicious patterns and threat indicators, and they complement other threat detection solutions. CIOs and CISOs must make informed decisions about NDR solutions, which are evolving to offer broader threat detection.

Market Definition

Gartner defines network detection and response (NDR) as products that detect abnormal network behaviors by applying behavioural analytics to network traffic data. NDR products continuously analyze raw network packets or traffic metadata within internal networks(east-west) and between internal and external networks (north-south). They include automated responses, such as host containment or traffic blocking, implemented directly or through integration with other cybersecurity products. Vendors deliver NDR as hardware or software appliances for sensors, with some supporting IaaS environments. Management and orchestration consoles are available as software or SaaS.

Organizations rely on NDR to detect and contain post breach activities such as ransomware, insider threats and lateral movements. NDR complements other technologies that primarily trigger alerts based on rules and signatures by building heuristic models of normal network behavior and detecting anomalies.

Security teams commonly use NDR as a complementary detection and response technology within a broader set of security operations center (SOC) tools. These include security orchestration, automation and response (SOAR), security information and event management (SIEM), endpoint detection and response (EDR), and other detection technologies.
