// THREAT DETECTION AND DATA PRIVACY TERM

XDR

Extended Detection and Response (XDR) is a cybersecurity tool that collects and automatically correlates data from multiple security layers, such as endpoints, email, and cloud services. This unified view helps security teams detect and respond to complex threats faster than with separate, siloed tools.

TECHNICAL DEFINITION

Extended Detection and Response (XDR) is a unified security incident detection and response platform that integrates and correlates telemetry from multiple security domains like endpoint (EDR), network (NDR), cloud, and email security. By applying analytics and machine learning to this cross-domain dataset, XDR enhances threat visibility, automates investigation workflows, and enables coordinated responses to sophisticated cyberattacks across the entire IT ecosystem.

BACKGROUND

Vectra AI, Inc. is a cybersecurity company that uses AI for hybrid attack detection, investigation, and response (NDR) solutions. The company was established in 2011 and operates in 113 countries from its San Jose, California headquarters, with further locations in Singapore, Australia, and Japan.
