Extended Detection and Response (XDR) is a cloud-native, cloud-scale solution that unifies and transforms multiple security telemetry sources with a goal of accelerating more comprehensive threat detection and response. This means security teams can rapidly and act on more precise insights to find and take down threats.
As attack surfaces expand, the odds will always favor the threat actor. In anticipation of this, it seems natural to extend detection and response powers to be more proactive, encompassing, and prescriptive—to find threats earlier and respond/remediate faster.
The modern XDR solution is cloud-native and prioritizes high-fidelity out-of-the-box detections and automation, finding and extinguishing real threats faster. This means leveraging multidimensional intelligence to take downexternal threats that directly target a business.
XDR does this by correlating data across diverse sources to recognize threats across the attack chain. This data is analyzed and transformed into a centralized, cohesive representation of incidents. XDR provides playbooks to guide threat response combined with automation. This results in faster mean time-to-detection (MTTD) and mean time-to-response (MTTR).
Traditional Security Information and Event Management (SIEM) offerings largely focus on data and log aggregation, dashboarding, and reporting that is critical for compliance, monitoring, and forensic activities. This is a subset of the scope of XDR, as a SIEM’s true focus is consolidating and unifying security telemetry into a single hub for comprehensive threat detection and response.
If you're in the market for an XDR solution, you’re most likely interested in collecting data from across many different vectors, and then unifying it into actionable intelligence. This means seeking out rapid scalability, integration of internal and external insights, and visibility beyond SIEM logs. And, hopefully, much of that process will be as automated as possible.
Your visibility and ability to respond across multiple threat vectors are what matter most, thus your organization’s XDR solution should deliver greater signal-to-noise by leveraging advanced telemetry and analytics. It should also provide a comprehensive, scalable hub so the modern Security Operations Center (SOC) can secure an ever-expanding perimeter.
Modern XDR capabilities save SOCs more time by rapidly scaling to pull in multiple sources of security telemetry. Users get more built-in efficiency with expansive coverage, significant noise reduction, and even more precise detections.
