If you’re anything like me, then hearing the term "XDR" might induce an involuntary eye roll. The term initially felt like yet another buzzword, coined ambiguously and brandished without a clear definition. Pose the question, "What is XDR?" to a group, and you'd likely be met with a myriad of differing answers, each as vague as the next. Over time, however, as with its counterparts NDR and EDR, the term XDR has cemented its place in the cybersecurity lexicon. The consensus? XDR is essentially about the 'analysis of stuff.' As unspecific and, let's admit, slightly exasperating as that sounds, it's become our industry's standard.
