NDR — Network Detection & Response — visibility inside the network that the firewall doesn't have

NDR analyzes traffic inside the network and detects threats that bypassed the perimeter — lateral movement, data exfiltration, unauthorized scanning, and C2 communication. You see what's happening on the network in real time.

NDR capabilities scope

NDR is a technology that complements firewall and EDR with visibility into traffic inside the network — where attackers operate after bypassing the perimeter.

East-West traffic analysis

Monitoring traffic inside the network (between devices) — not just incoming traffic from outside. After entering the network, attackers move laterally — NDR detects this.

Behavioral detection and ML

Machine learning algorithms create a baseline of normal network behavior. Any deviations — new connections, unexpected traffic, port scanning — generate alerts without signatures.

Lateral movement detection

Detection of traffic characteristic of attackers moving across the network — SMB scanning, pass-the-hash, credential dumping, unauthorized RDP connections.

Data exfiltration detection

Analysis of data transfer patterns — unusual amounts of data sent outside, connections to suspicious IP addresses, C2 (command & control) traffic.

OT/IoT device visibility

Monitoring industrial devices, cameras, printers, and other IoT devices — which often don't support traditional EDR agents.

SIEM and SOAR integration

NDR provides network context to SIEM — enriching events with information about connections, protocols, and devices. Automated response via SOAR — blocking suspicious hosts.

Sycope

Polish NDR platform — advanced network traffic analysis and threat detection. Enterprise-class solution developed in Poland.

An attacker spends an average of 200 days on the network before being detected

200 days is the time an attacker has to scout the network, steal data, and install backdoors.

The firewall stops traffic from outside. EDR protects workstations. NDR is the missing layer — monitoring what happens inside the network.

FAQ

NDR questions

The firewall filters network traffic at the network boundary (North-South). EDR protects individual devices. NDR analyzes traffic inside the network (East-West) — between devices, between segments. These are three complementary protection layers. Each assumes the others may fail.
NDR analyzes network traffic metadata (NetFlow, IPFIX) or a copy of the traffic (SPAN/TAP). It doesn't require installation of agents on devices — it sees everything passing through the network, including traffic from IoT, OT, and printer devices.
Modern ML-based NDR platforms generate significantly fewer false alarms than signature-based systems. After the learning phase (typically 2–4 weeks), the system knows the network baseline and alerts only on real anomalies. Alerts are prioritized by importance.
NDR is especially valuable for companies with extensive network infrastructure, sensitive data, or regulatory requirements (NIS2, ISO 27001, financial sector). For smaller companies, a good starting point is NGFW with IPS and EDR — NDR can be added as the next step.
