While organizations deploy various security technologies, modern cyberattacks are often intricate, involving kill chains composed of numerous low-fidelity signals. A key challenge is correlating these alerts across siloed security solutions to gain a complete, enterprise-wide view of the threat.
Adding to this complexity, many legacy security tools were not designed for today's hybrid environments, resulting in significant gaps in visibility and coverage. Then, compounding these technical hurdles even more is the high demand for skilled security professionals, which frequently leaves security operations centers (SOCs) overwhelmed by a flood of alerts and a backlog of incidents requiring investigation and remediation. SecOps teams often grapple with disjointed security solutions, lacking the necessary integration, intelligence, and expertise for efficient incident resolution.
As a direct result of these needs and changes was the development of MXDR directly from managed detection and response (MDR) and extended detection and response (XDR).
MDR services began to gain notice between 2015 and 2020 and helped security teams expand beyond simple monitoring to include 24/7 threat detection, analysis, and response, often leveraging Endpoint Detection and Response (EDR) technology. MDR was designed to provide a human-led security operation to detect, hunt, and respond to threats across endpoints.
Extended Detection and Response (XDR) emerged as a natural evolution of EDR and MDR. While MDR security services primarily focus on endpoints, XDR broadened its scope to integrate and correlate telemetry data from a much wider range of security sources, including endpoints, networks, cloud environments, identities, and applications. The goal was to provide a more unified and contextual view of threats across the entire digital ecosystem.
MXDR brings all of these together, delivered as a service, combining the advanced capabilities of XDR technology with the human expertise of a managed security service provider (MSSP).
The right tool in the box is important, but other crucial components needed are people. Highly trained experts, that work within a proven security operations process, with access to dynamic content, and relevant adversarial threat intelligence. This is where a managed extended detection and response (MXDR) service comes into play, providing the comprehensive approach and expertise required to actively combat the modern cyber threat.
An MXDR service offers 24/7 global security operations. This includes extended detection, investigation, threat hunting, and response capabilities. The goal is to effectively disrupt complex threats across the attack chain soon after they are detected by taking effective, native response actions for swift and effective incident resolution. This involves a thorough human-led investigation process and can leverage AI for accelerated investigation and response capabilities for faster resolution.
Beyond reactive response, a mature MXDR service should also focus on proactive defense with a team of cyber domain experts. This includes implementing proven preventative configurations and continuously optimizing technology, intelligence, and processes to maximize an organization's defensive posture and minimize overall threat exposure.
By partnering with an MXDR provider, organizations can realize significant benefits. These include having unified visibility across your security operations with the ability to eliminate active threats 24x7, globally, and disrupt complex threats across the attack chain. It helps enhance your existing team and accelerate the productivity of your security operations team.
