Network Detection & Response (NDR)
Visibility into network traffic to detect lateral movement, command-and-control and data theft that endpoint tools cannot see.

Overview
Endpoint tools see only the devices where they run. Attackers who reach network equipment, legacy servers or unmanaged systems can move quietly, and data can leave through channels no agent watches.
NDR watches the network itself. We design and deploy NDR so your team can detect lateral movement, command-and-control and data theft across the whole environment.
What you get
- Visibility into east-west and north-south traffic, including unmanaged devices
- Detection of lateral movement, command-and-control and unusual data transfers
- Network evidence to support investigations
- Coverage for systems that cannot run endpoint agents
What we cover
- Sensor placement and traffic capture design
- Encrypted traffic analysis and metadata inspection
- Detection of lateral movement and command-and-control
- Operational technology and legacy network segments
- Integration with SIEM, XDR and ticketing

How we work
-
Map the network
We identify critical segments, traffic chokepoints and systems that cannot be protected by agents.
-
Design sensors
We plan sensor placement, traffic mirroring and capacity so coverage matches your risks.
-
Deploy and baseline
We deploy sensors, confirm traffic is captured and let the platform learn normal behavior.
-
Tune and integrate
We tune detections, remove noise and send alerts to your SIEM or XDR.
-
Hand over
We train analysts to investigate network alerts and document the design.
Deliverables
- Sensor placement design and capacity plan
- Deployed and tuned NDR platform
- Coverage report by network segment
- Integration with existing security tools
- Analyst training and documentation
Questions buyers ask
Do we still need NDR if we have XDR?
Often yes. XDR sees managed endpoints; NDR also sees servers, network devices and systems where agents cannot be installed.
