MXDR stands for Managed eXtended Detection and Response.

It is a fully managed cyber security service that combines advanced threat detection, continuous monitoring, incident response, and human-led expertise into one solution. Unlike traditional tools, MXDR goes beyond detection; it ensures that threats are actively investigated and contained by a dedicated 24/7 Security Operations Centre (SOC).

MXDR works by ingesting data from across your entire IT environment: endpoints, cloud services, email, networks, and identities, and unifying it through a single platform to provide enhanced visibility of the attack surface. Using AI-assisted threat intelligence, behavioural analytics, and real-time monitoring, it identifies suspicious activity that might bypass traditional defences. When threats are detected, security analysts in PureCyber’s 24/7 SOC team investigate and take immediate action to mitigate risk, contain the attack, and guide you through remediation.

EDR (Endpoint Detection and Response): Focuses only on monitoring and responding to threats on devices like laptops and servers.

MDR (Managed Detection and Response): A managed service where a provider monitors and responds to threats on your behalf, usually limited to endpoints.

XDR (Extended Detection and Response): Expands visibility beyond endpoints to include cloud, email, identity, and network data.

MXDR (Managed Extended Detection and Response): The most comprehensive option — a fully managed service that provides round-the-clock monitoring, expert response, and proactive threat hunting across all layers of your IT environment.

Yes. XDR and MXDR often incorporate SIEM (Security Information and Event Management) capabilities, but with significant improvements. While SIEM collects and stores logs, XDR/MXDR provides real-time correlation, automated response, and human-led analysis. PureCyber’s MXDR combines the power of SIEM data with AI-driven threat detection and a 24/7 SOC team, giving you both visibility and action when it matters most.

Microsoft MXDR is a managed cyber security service built around Microsoft’s security stack, such as Defender, Sentinel, and Entra. It offers detection and response services tailored to Microsoft environments. PureCyber’s MXDR is vendor-agnostic, meaning it integrates data and protection across multiple tools, providers, and environments, not just Microsoft, ensuring comprehensive coverage for all your systems, apps, and cloud platforms.

Yes. XDR and MXDR are far more advanced than antivirus software. Traditional antivirus only blocks known malware, whereas XDR/MXDR provides holistic detection, monitoring, and response across your entire IT ecosystem. This includes zero-day threats, phishing attempts, supply chain attacks, and insider risks. MXDR combines AI-driven analytics with human expertise, ensuring your organisation is protected against both common and sophisticated cyber attacks.

Adaptive MXDR refers to a flexible, intelligence-driven approach to Managed Extended Detection and Response. Rather than being a one-size-fits-all solution, adaptive MXDR adjusts to your organisation’s evolving threat landscape, IT infrastructure, and compliance requirements. PureCyber’s MXDR is adaptive by design. Our Cardiff-based analysts continuously refine detection rules, integrate new threat intelligence, and adapt response strategies so your organisation is always protected against the latest risks.
