What is NDR and Why It Matters

Network Detection and Response (NDR) provides visibility into network traffic to detect threats, anomalous behavior, and lateral movement that endpoint tools miss.

🔍

East-West Visibility

Monitor lateral movement and internal network traffic that firewalls and perimeter tools can't see.

🧠

Behavioral Analytics

AI-powered detection of anomalous network behavior, C2 communication, and data exfiltration patterns.

Real-Time Detection

Continuous network traffic analysis with sub-second detection of active threats and attacker reconnaissance.

📊

Forensic Investigation

Full packet capture and network metadata for post-incident analysis and threat hunting.

NDR vs Traditional IDS/IPS

Modern NDR

  • Machine Learning: AI-powered behavioral analytics detect unknown threats
  • Entity Tracking: Tracks devices, users, and applications across the network
  • Automated Response: Integrates with firewalls, NAC, SOAR for auto-remediation
  • Cloud-Ready: Analyzes hybrid cloud, container, and multi-cloud traffic
  • Low False Positives: Context-aware detections reduce alert fatigue
  • Investigation Tools: Timeline analysis, threat hunting, incident reconstruction

Legacy IDS/IPS

Legacy
  • Signature-Based: Only detects known threats with pre-defined signatures
  • Flow Analysis: Basic NetFlow/sFlow analysis without deep inspection
  • Manual Response: Requires SOC analyst intervention for every alert
  • On-Premises Only: Limited visibility into cloud and SaaS traffic
  • High Alert Volume: Floods SOC with alerts, many false positives
  • Limited Context: Lacks investigation tools and historical context

5 Key Factors in NDR Sizing

1

Network Bandwidth

What to measure: Peak traffic throughput across all monitored network segments, SPAN/TAP ports, and cloud environments.

Why it matters: NDR pricing is primarily based on Gbps monitored. Underestimating bandwidth leads to dropped packets and missed threats.

Best practice: Measure actual peak usage + 30% headroom. Include cloud egress, VPN tunnels, and inter-datacenter links.

2

Traffic Collection Method

What to measure: SPAN/Mirror ports, network TAPs, virtual taps, cloud VPC flow logs, or host-based sensors.

Why it matters: TAPs provide 100% visibility but cost more. SPAN ports are cheaper but can drop packets under load.

Best practice: Use TAPs for critical segments (datacenter core, DMZ). SPAN for branch offices. Virtual sensors for cloud workloads.

3

Packet Capture vs Metadata

What to measure: Full packet capture (PCAP) vs network metadata/flow logs. PCAP requires 100x more storage.

Why it matters: PCAP enables deep forensics but is expensive at scale. Metadata is sufficient for most detection use cases.

Best practice: Continuous metadata + selective PCAP triggers on alerts. 7-30 days PCAP retention for critical segments only.

4

Data Retention Period

What to measure: Days of network metadata and PCAP storage required for compliance and investigation.

Why it matters: Longer retention enables historical threat hunting but scales storage costs linearly.

Best practice: 90 days metadata is standard. 365 days for compliance (HIPAA, PCI-DSS). Tiered storage for cost optimization.

5

Detection Coverage Scope

What to measure: Network segments to monitor: internet edge, datacenter core, remote sites, cloud VPCs, OT/ICS networks.

Why it matters: Each network segment requires sensors and bandwidth allocation. More coverage = higher cost but better security.

Best practice: Start with datacenter + internet edge. Expand to branches and cloud. OT networks require specialized NDR tools.

4 Common NDR Sizing Mistakes

⚠️

Underestimating Bandwidth Growth

Many organizations size for current bandwidth and forget to plan for growth. Cloud adoption, video conferencing, and SaaS traffic grow 40-60% year-over-year.

Fix: Size for 2-3 year projected bandwidth. Build in 30-50% headroom. Choose vendors with flexible licensing models.

⚠️

Forgetting Cloud Traffic

NDR often focuses on datacenter traffic and ignores cloud VPC traffic, container networks, and serverless environments. Modern attacks target cloud workloads.

Fix: Include AWS VPC, Azure vNet, GCP VPC flow logs in bandwidth calculations. Ensure NDR supports cloud-native deployments.

⚠️

Over-Investing in PCAP Storage

Full packet capture at 10 Gbps generates 100+ TB per day. Many organizations buy massive storage arrays they never fully utilize.

Fix: Use triggered PCAP (capture on alert only). Store metadata continuously, PCAP selectively. Consider cloud storage for long-term archives.

⚠️

Ignoring Integration Costs

NDR value comes from integration with SIEM, SOAR, firewalls, and endpoint tools. Integration requires staff time, APIs, and sometimes professional services.

Fix: Budget 20-30% of NDR cost for integration and tuning. Choose vendors with pre-built connectors for your security stack.
