Network Detection and Response

Protect your network by eliminating blind spots. Full visibility over the traffic inside your network, with malicious activity surfaced automatically.

Overview

No more internal blind spots.

Networks can have both internal and external blind spots. As attacks become more sophisticated, relying solely on perimeter protection and assuming the internal network is secure is no longer enough. Organizations must operate under the assumption that an attacker may already be inside.

That calls for full monitoring of the traffic inside your network, and the ability to quickly separate malicious activity from legitimate traffic to mitigate attacks before they can do harm. Because Open Systems devices already sit where your traffic is conducted, enabling complete visibility is as easy as clicking a button.

How it works

Correlated, then surfaced.

IDS and IPS on Open Systems Firewalls, Secure Web Gateways or dedicated sensors feed network data to the correlator
The correlator analyzes the matched signatures and assigns threat scores accordingly
Assets with a high threat score generate an alert; low-value noise is filtered out
After activation and baselining by Open Systems, events are correlated globally and only suspicious ones surface, sparing you tedious filtering
Level-3 engineers investigate and respond around the clock

Benefits

Benefits.

Complete visibility

See east-west and north-south traffic inside your network, not just at the perimeter.

Assume-breach ready

Detect lateral movement and threats already inside, in line with a zero trust posture.

Global correlation

Events correlate across your whole estate; only genuinely suspicious activity surfaces.

Managed for you

Activation, baselining, investigation and response handled by Level-3 engineers, 24/7.

One platform

Part of Threat Defense.

NDR works alongside Advanced Threat Protection, Cloud Sandbox, Email Security and Managed Detection & Response in one managed platform, on a 35-year operational baseline.

FAQ

Questions about NDR.

How is NDR different from a firewall or an IDS?

A firewall decides what may cross a boundary; an IDS flags a matching signature. NDR watches the traffic inside the network, east-west as well as north-south, correlates those events across your whole estate and scores the asset rather than the packet. The firewall stops what it was told to stop. NDR finds what nobody told it to look for yet.

Do we have to install new hardware to get it?

Usually not. Open Systems devices already sit where your traffic is conducted, so IDS and IPS on the firewalls and Secure Web Gateways can feed the correlator directly, which is why enabling visibility is close to a switch you flip. Dedicated sensors exist for segments we do not otherwise touch, such as a plant network.

Will this bury my team in alerts?

That is the failure mode we design against. Signatures are matched and scored first, low-value noise is filtered out, and events are correlated globally so only genuinely suspicious activity surfaces. Then Level-3 engineers investigate it before you hear about it. What reaches you is an incident, not a queue.

Can NDR see anything useful in encrypted traffic?

Yes. Detection works on behaviour and metadata, connection patterns, volumes, timing, destinations and lateral movement, which stay visible whether or not the payload is readable. Where SSL inspection is enabled on the Secure Web Gateway or firewall, the decrypted stream is inspected too.

How does NDR relate to MDR?

NDR is the detection surface on the network; MDR is the managed service that owns detection and response across the estate. They sit in the same Threat Defense module and on the same 35-year baseline, and most customers who buy NDR also want somebody to answer the alert at three in the morning.

How long before it is actually useful?

After activation there is a baselining period, run by us, in which the correlator learns what normal looks like in your environment. That step is the difference between a system that surfaces real anomalies and one that alerts on your Monday morning backup window forever.
