NDR Market Overview

NDR Market Overview

What is Network Detection and Response (NDR)?

Network Detection and Response (NDR) is a cybersecurity solution that continuously monitors network traffic to detect threats and suspicious activities using advanced analytics, machine learning (ML), and artificial intelligence (AI). Unlike traditional signature-based systems, NDR establishes a baseline of “normal” network behavior and identifies anomalies that signal emerging threats.
