Introduction

As cyber threats become increasingly sophisticated, organizations are turning to advanced network security solutions such as Network Detection and Response (NDR) to enhance their threat detection and response capabilities. NDR tools provide deep visibility into network traffic, allowing security teams to detect, investigate, and respond to malicious activity that might otherwise go unnoticed. Among the leading NDR platforms, Corelight and Vectra have emerged as key players, each offering distinct advantages in terms of deployment, detection capabilities, scalability, and integration.
