XDR represents the evolution of detection and response beyond the current point-solution, single-vector approach.
Endpoint detection and response (EDR) has been enormously valuable. However, despite the depth of its capability, EDR is restricted because it can only look at managed endpoints. This limits the scope of threats that can be detected as well as the view of who and what is affected, and thus, how best to respond.
Likewise, network traffic analysis (NTA) tools' purview is limited to the network and monitored network segments. NTA solutions tend to drive a massive number of logs. The correlation between network alerts and other activity data is critical to make sense and drive value from network alerts.
The industry has made great strides in detection and response, but to date has only delivered the capabilities via an individual solution and security layer. As a result, data collection and analysis benefits have remained siloed. XDR evolves detection and response into a consolidated, centralized activity that delivers results greater than the sum of the parts.
