Breadcrumb Home Insights Cybersecurity Dictionary XDR – Extended Detection and Response Optiv Cybersecurity Dictionary Breadcrumb Home Insights Cybersecurity Dictionary XDR – Extended Detection and Response What is XDR – Extended Detection and Response? XDR represents an emerging class of tools that aggregate and analyze data from multiple point products to help security operations teams improve the efficacy of threat detection and accelerate incident response. XDR Tools XDR tools harness telemetry from pre-built integrations, and interoperate with endpoint, network, email, cloud, SIEM/SOAR and other solutions. In pursuit of expanded visibility, XDR is the logical evolution beyond single-product platforms like EDR (endpoint detection and response) or NDR (network detection and response). XDR uses artificial intelligence (AI)/machine learning (ML) techniques to correlate activity across these multiple solutions to help isolate true threats from all of the noise. XDR tools have some overlapping capabilities with SIEM and SOAR solutions and it will be interesting to watch as vendors in these segments compete going forward. Image XDR - Extended Detection and Response: Why It Matters The quicker you can sniff out cyber threats, the quicker you can nip them in the bud. As the emergent successor of single-product platforms, XDR technology promises to improve, if not revolutionize, the ways in which impending threats are detected. It’s true that XDR brings visibility back to your data, but it also brings context surrounding all potential threats — which are analyzed, prioritized, hunted and remediated before they can wreak havoc on your organization.

MXDR accelerates incident investigation (data and case enrichment, analysis, classification and response) while providing clients a threat-informed defense approach, rather than relying on (the availability of) humans. Of course, it’s also backed by our deep technical expertise, intelligence and unrivaled industry experience. Work with us and let us prove it. Meet MXDR Image Related Terms EDR – Endpoint Detection and Response Endpoint Detection and Response (EDR) solutions record key activity of endpoints and provide security analysts with necessary information to conduct both reactive and proactive threat investigations. See Full Description SOAR – Security Orchestration, Automation and Response Security orchestration, automation and response (SOAR) is a term developed by Gartner to describe technology platforms that aggregate security intelligence and context from disparate systems, and apply machine intelligence to streamline (or even completely automate) the incident detection and response process. See Full Definition SIEM – Security Information and Event Management SIEM is a software tool that allows security operations teams to identify potential incidents by consolidating and correlating log data from many other tools in the environment. See Full Definition Managed Detection and Response Managed detection and response (MDR) is an outsourced service that leverages external experts to make the security benefits of tools like EDR and proactive threat hunting accessible to customers of all maturity levels.
