Network Detection & response

Protocol-aware inspection. Beaconing detection. Lateral movement.

Overview

What NDR does.

Network Detection and Response captures flow and packet metadata from your VPCs, on-prem switches and remote sites. Protoxol NDR ships software sensors (no appliances) that parse over 60 protocols deep — DNS, HTTP, SSH, RDP, SMB, Kerberos and more — and write to the same event bus as EDR. Result: an analyst sees a process spawn on a host and the outbound C2 beacon as two rows of the same timeline.

Features

Inside NDR.

Protocol-aware inspection

60+ protocols parsed at line rate. Zeek-grade detail without Zeek operations.

Beaconing detection

Statistical jitter analysis identifies C2 beacons even with random sleep.

Encrypted traffic analysis

JA3/JA4 fingerprinting, certificate metadata, SNI analysis — without decryption.

Cloud-native sensors

Run as DaemonSet on Kubernetes, sidecar on ECS, or VPC mirror tap on AWS/Azure/GCP.

Lateral movement detection

Cross-host graph analytics catch east-west attacks invisible to perimeter tools.

Use cases

Where NDR earns its keep.

C2 beacon discovery

Find dwelling threats via long-tail outbound patterns, not signature matches.

Unmanaged device discovery

Inventory every IP that talks on the network — IoT, OT, contractor laptops, shadow VMs.

Data exfiltration

DNS tunneling, abnormal volume to new destinations, suspicious upload bursts.

Technical specs

NDR under the hood.

Throughput 10 Gbps per sensor instance
Deployment Container, VM mirror, VPC tap
Encryption support TLS 1.2/1.3 metadata + JA3/JA4
Retention Flows: 1 year, Packets: 7 days
The landscape

Where the market stands today.

Network telemetry catches what endpoints miss — unmanaged devices, lateral movement, C2 beaconing. The market splits between heavy appliances and cloud-native NDR. Protoxol NDR is the second kind.

Vendor Strength Tradeoff
Darktrace Strong unsupervised ML. Anomaly framing. Black-box detections. Costly tuning.
ExtraHop Reveal(x) Decryption at scale. Strong forensics. Appliance-first. Cloud story still maturing.
Vectra AI AI attack signals. Good cloud coverage. Pricing opaque. Sometimes noisy on quiet networks.
Our offering
