XDR

Extended Detection and Response is a security technology that collects and automatically correlates data across multiple layers such as email, endpoint, server, cloud, and network, into a unified detection and response platform.

XDR stands for eXtended Detection and Response. It is an evolution in cybersecurity defense that extends beyond the capabilities of traditional endpoint detection and response (EDR) solutions. The primary goal of XDR is to improve upon the complexities introduced by point security products, and instead provide a comprehensive, integrated security solution.

XDR collects and automatically correlates data across multiple security layers - email, endpoint, server, cloud workloads, and network - so threats are detected faster and security analysts can improve investigation and response times. In essence, it stitches together disparate security technologies into a unified security and incident response platform.
