Network Detection & Response
Best Network Detection & Response (NDR) Platforms in 2026
Network Detection and Response (NDR) platforms use AI and machine learning to analyze network traffic, detect threats that bypass traditional security controls, and enable rapid investigation and response. These tools are essential for detecting lateral movement, insider threats, and advanced persistent threats across hybrid and cloud environments.

Network Detection & Response FAQ
What is Network Detection and Response (NDR)?
NDR platforms monitor network traffic using AI and machine learning to detect threats that bypass traditional security controls like firewalls and endpoint protection. They analyze network metadata and packets to identify lateral movement, data exfiltration, insider threats, and advanced attacks, then enable rapid investigation and automated response.
How does NDR differ from EDR and SIEM?
EDR focuses on endpoint-level threats (malware, ransomware on devices), SIEM aggregates and correlates logs from multiple sources, and NDR analyzes network traffic patterns. NDR catches threats that endpoints miss (like IoT compromise or lateral movement between servers) and provides context that logs alone cannot reveal. Most security teams use all three together as part of the SOC visibility triad.
Do I need NDR if I already have a firewall?
Yes. Firewalls block known threats at the perimeter, but NDR detects threats that are already inside your network — lateral movement, compromised credentials, encrypted command-and-control traffic, and insider threats. NDR assumes breach and focuses on detecting what firewalls miss.
How much do NDR platforms cost?
NDR platforms are typically enterprise-priced. Darktrace, Vectra AI, and ExtraHop all use custom pricing based on the volume of network traffic monitored and the number of sensors deployed. Expect annual costs starting from ,000-,000 for mid-market deployments, scaling significantly for large enterprises with high traffic volumes.
