XDR represents the evolution of detection and response beyond the current point-solution, single-vector approach.
Clearly, endpoint detection and response (EDR) has been enormously valuable. However, despite the depth of its capability, EDR is restricted because it can only detect and respond to threats inside managed endpoints. This limits the scope of threats that can be detected as well as the view of who and what is affected. These restrictions ultimately limit response effectiveness within the SOC.
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.
