Network Detections & Response (NDR) Buyers Guide

NDR evolved out of Network Security.
NDR ensures full visibility and verifies Zero Trust

Analyzing endpoint data and security tool logs is not enough
to thwart today’s attacks. If there is one important thing
to know about the network traffic, it’s that it doesn’t lie.

Network Detections & Response (NDR) Buyers Guide

What is Network Detection & Response?

NDR evolved out of Network Security

Today’s network detection and response (NDR) has a long history, evolving out of network security and network traffic analysis (NTA). The historical definition of network security is to use a perimeter firewall and Intrusion Prevention Systems to screen traffic coming into the network, but as IT and security technology have evolved, the definition is much broader now due to modern attacks leveraging more complex approaches.

Today, network security is everything a company does to ensure the security of its networks, and everything connected to them. This includes the network, the cloud (or clouds), endpoints, servers, IoT, users and applications. Network security products seek to use physical and virtual preventive measures to protect the network and its assets from unauthorized access, modification, destruction and misuse.

Stellar Cyber's Interflow Delivers Value & Visibility

Interflow is an integral part of the Stellar Cyber Open XDR platform

A data extraction engine with a powerful DPI functionality that extracts telemetry from packets and a fusion engine that automatically makes your telemetry more valuable.

PCAP:Too much data to store and too hard to analyze
Netflow:Not enough data to be useful while limited by switches / routers
IDS:Not scalable; too noisy and too expensive
NGFW*:Not enough data and limited scale
Sandbox:File based malware only and very expensive
DPI/Metadata:Good balance of fidelity and cost; easy to deploy
NDR/NTA:Often noisy and expensive
