What Is XDR vs. MDR?
Exploring Extended Detection and Response (XDR)
Extended detection and response, or XDR, is a new approach to threat detection and response. According to Forrester Research, XDR “optimizes threat detection, investigation, response, and hunting in real time. XDR unifies security-relevant endpoint detections with telemetry from security and business tools such as network analysis and visibility (NAV), email security, identity and access management, cloud security, and more”.
The “X” in XDR stands for “extended”, but it really represents any data source, recognizing that it’s not efficient or effective to look at individual components of an environment in isolation. XDR brings a proactive approach to threat detection and response, delivering visibility across networks, clouds, and endpoints while applying analytics and automation to address today’s increasingly sophisticated threats.
Key Differences Between MDR and XDR
(New) While both XDR and MDR share the overarching goal of elevating threat detection and response capabilities, XDR is a product designed to help security teams, managed or in-house, handle threats. On the other hand, MDR is a service designed to help organizations take action in the event of a cybersecurity incident. Often, MDR teams make use of tools like XDR to provide services. Therefore, it's essential to recognize that these two approaches are not in competition but rather synergistic.
Integration and analytics: MDR operates with a suite of security tools and technologies tailored for monitoring and analyzing network data. It delivers invaluable insights within the network perimeter. However, MDR solutions might lack seamless integration with other security tools and platforms, potentially limiting its ability to correlate data and discern intricate attack patterns. XDR, in contrast, seamlessly integrates with an extensive array of security technologies. It harnesses the power of advanced analytics, machine learning, and threat intelligence to dissect and interconnect security events across diverse platforms. This integration, coupled with advanced analytics, equips XDR to offer a holistic and contextually rich comprehension of security threats.
Context and incident response: The security experts comprising an MDR team delve into alerts, curtail threats, and set in motion remediation protocols to reinstate normal operations. XDR transcends the confines of network perimeters, presenting a panoramic view of the attack chain. Through adept correlation of data spanning various security layers, XDR equips security teams with an encompassing context of security events. This broader context empowers them to formulate informed decisions and take preemptive measures to effectively mitigate threats.
