Network Detection & Response

Network Detection & Response
  • NDR: Monitors, analyzes, detects, and responds to malicious activity in network traffic.
  • Purpose: Detects threats bypassing traditional defenses, including APTs, insider threats, and zero-day attacks.
  • Network Visibility: Provides deep insight into north-south and east-west traffic, on-premises and cloud.
  • Threat Detection: Uses AI/ML, behavioral analytics, and threat intelligence to identify anomalies like lateral movement, data exfiltration, and unusual protocols.
  • Incident Investigation: Provides packet capture, session details, and metadata for root-cause analysis.
  • Automated Response: Can block malicious traffic, isolate endpoints, or alert SIEM/SOAR systems.
  • Benefits: Advanced threat detection, faster response, network forensics, improved SOC efficiency, supports cloud/hybrid security.
  • Use Cases: Detect lateral movement, identify C2 traffic, spot data exfiltration, monitor IoT/unmanaged devices, complement SIEM/EDR.
  • Popular Solutions: Darktrace, Vectra AI, ExtraHop Reveal(x), Cisco Secure Network Analytics, Corelight.
  • NDR in Security Stack: Complements EDR, SIEM, and SOAR; integration forms XDR for holistic detection and response.
