Extended Detection and Response (XDR) technology is quickly taking the enterprise cybersecurity industry by storm.
The term XDR, first coined in 2018 by Omdia Principal Analyst Rik Turner, is defined by Omdia as a single, stand-alone solution that offers integrated threat detection and response capabilities.
To meet Omdia's criteria to be classified as a "comprehensive" XDR solution, a product must offer threat detection and response functionality across three key platforms:
- Endpoints (often referred to as Endpoint Detection and Response or EDR)
- Networks (often referred to as Network Traffic Analysis or NTA, more recently as Network Detection and Response or NDR)
- And cloud computing environments (occasionally referred to as Cloud Detection and Response or CDR).
Specific to the cloud, this should encompass software-as-a-service (SaaS) environments such as Office 365 and Salesforce, as well as infrastructure- and platform-as-a-service (IaaS and PaaS) modes of delivering cloud computing.
Support for other platforms or threat vectors — such as email — is also common, and XDR solutions may also foster integration among stand-alone threat detection and response solutions that specialize in any of the three areas noted above, as well as others.
Omdia has a comprehensive library of research on XDR, detailing how the technology works, the way in which it is already evolving, and what specific approaches various vendors have adopted.
