# What is NDR (Network Detection and Response)?

NDR is security software that watches network traffic, flags behaviour that looks like an attack and gives you the evidence to respond. Firewalls and endpoint agents each see their own device; NDR sees how hosts talk to each other — command-and-control beaconing, scanning, lateral movement and unusual outbound data. NetSenX is a Network Detection and Response (NDR) platform for EU mid-market organisations that detects attacks from network behaviour, explains every alert in plain language and keeps customer data in the EU.
