NDR · Network detection and response

Attackers move through your network. Traffic is where you see them.

Network detection and response analyses traffic at the perimeter and inside the estate, identifies the protocols in use, and flags the behaviour that precedes a breach: reconnaissance, lateral movement, tunnelling and communication with attacker infrastructure.

Encrypted and internal traffic

Encryption hides content. It does not hide behaviour.

Analytics work on session characteristics rather than payload, so activity concealed inside TLS or a custom protocol still stands out. East and west traffic is analysed alongside north and south, which is where lateral movement actually happens.

Investigation and hunting

Keep the traffic, so the investigation is possible.

Session metadata and raw traffic are retained, so an incident can be reconstructed rather than guessed at. Analysts can test a hypothesis against what really crossed the wire, and retrospective checks re-examine stored traffic when new indicators arrive.

Capabilities

What the platform gives you

Requirements we hold any network detection platform to before we recommend it.

Protocol identification and parsing

Dozens of application protocols identified and parsed to layer seven, so sessions are described in terms of what actually happened rather than byte counts.

Lateral movement detection

Reconnaissance, remote command execution and directory and authentication attacks are surfaced as behaviour, not as isolated packets.

Threats in encrypted traffic

Session analytics flag malicious activity concealed by TLS or non standard protocols without needing to break encryption everywhere.

Tunnelling and evasion

Data hidden inside DNS, HTTP, SMTP and ICMP traffic is detected, along with proxies and anonymity tooling used to slip past controls.

Command and control tracking

Connections to attacker infrastructure are identified, including domains produced by generation algorithms rather than fixed lists.

Retrospective analysis

When detection content is updated, stored traffic is re-examined, so an intrusion that was invisible last month does not stay invisible.

Full session retention

Metadata and raw traffic are kept for the retention period you set, giving investigators evidence instead of inference.

Policy violation visibility

Cleartext credentials, weak authentication, unapproved remote access tooling and prohibited services are surfaced as findings.

Filtering at scale

Sessions can be filtered across hundreds of parameters, which is what makes threat hunting practical rather than theoretical.

How it works

From packets on the wire to a session an analyst can read

Every stage removes ambiguity. Skip one and the analyst ends up reading packet captures by hand.

PerimeterData centreServer segmentsUser segmentsDomain controllersRemote access
01
Capture
Traffic mirrored from switch ports and network taps, at the perimeter and inside the network.
02
Decode
Protocols identified and parsed into sessions, with participants, actions and artefacts named.
03
Detect
Rules, analytics and indicators applied to sessions and to sequences of behaviour across them.
04
Retain
Metadata and raw traffic stored, so evidence exists when the investigation starts.
05
Hunt
Analysts filter, pivot and test hypotheses, and stored traffic is rechecked as new intelligence lands.
Deployment is passive. Traffic is copied, not intercepted, so nothing in the production path depends on the platform staying up.
Delivery model

You own it, we build it

The platform runs on your premises under your licences. We size the capture points, deploy the sensors, tune detection and train your analysts.

We monitor it for you

Our team watches the traffic, triages what the platform raises, hunts on your behalf and hands you incidents rather than alerts.

SIEM

Network detections correlated with endpoint, identity and application events in one queue.

EDR and XDR

Endpoint visibility that confirms what a suspicious session actually did on the host.

Incident response

Retained traffic is what turns a suspicion into a defensible timeline.
