  2022 Predictions By Aimei Wei Initial definitions of  XDR  envisioned  eXtended Detection and Response  – a single platform that unified  detection and response  across the entire security  kill chain . According to Rik Turner, who coined the  XDR acronym ,  XDR  is  “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 endpoints, networks and cloud computing environments. Gartner’s definition is similar in that it points to features such as alert and incident correlation, built-in automation, multiple streams of telemetry, multiple forms of detections (built in detections), and multiple methods of response. However, Gartner requires  XDR  to be achieved through consolidating multiple proprie...

  Resource strapped companies trying to put together a comprehensive  cybersecurity  defense in today’s environment have three key challenges: there’s not enough time, there aren’t enough people, and there isn’t enough money.

Doing nothing means you put your entire business in danger because a serious attack can take you out of business. So, you can either continue to watch your analysts drown in a sea of largely meaningless alerts, or you can choos...
