Open XDR does not replace your tools. Rather it acts as the integration hub for security analytics and operations as a “manager of managers,” integrating various tools including SIEM, EDR, NDR, public clouds, and individual point tools and business applications to extract maximum value in the form of higher fidelity alerts and automated processes across the security lifecycle. It makes the analysts’ job easier and gives security leaders higher ROI on their investments and confidence in their security.
What is Open XDR?
XDR stands for eXtended (or Cross Platform) Detection and Response. Its purpose is to integrate disparate tools across the security stack—SIEM, EDR, cloud and others to deliver a single, complete view of threats so you can detect, investigate and respond faster to protect your business.
Unlike vendor-specific eXtended Detection and Response platforms, Open XDR security (or Hybrid XDR) is vendor-agnostic delivering deep integration across best-of-breed tools from a diverse set of vendors. Additionally, Open XDR delivers the right combination of technology, field-validated content and resource empowerment to increase visibility, reduce complexity and manage risk.
Think of XDR as a modern SOC-in-a-box designed to integrate controls, normalize telemetry, provide advanced analytics, and automate responses.Jon Oltsik Senior Principal Analyst, and ESG FellowESG
Open XDR VS. EDR VS. SIEM
SIEM tools focus on bringing together data from security sources that primarily focus on the network, while EDR products focus on detecting advanced threats and monitoring behavior on endpoints. While there can be overlaps where some SIEM tools ingest endpoint data, they lack fidelity and require specific data models. Open XDR security builds on the strengths of SIEMs and EDRs and extends these tools. It delivers singular contextual visibility across the enterprise by aggregating the relevant data from any and all sources, including SIEM and EDR, regardless of deployment model—on-premises, cloud, or hybrid—eliminating any blind spots. Unlike SIEM and EDR tools, Open XDR doesn’t require another data lake or repository or specific data models, it natively collects relevant data, just-in-time, reducing complexity and saving costs.

Open XDR VS. VS. MDR VS. Managed Services
Managed service providers can help organizations with certain aspects of their security practices. Starting from an event and incident management discipline, some providers have grown to offer managed detection and response (MDR) solutions. But they are limited by their processes and the tools they employ—mostly single-vendor—and their business models most often emphasize generic approaches, and may even charge by incident or by the hour. While these service providers may work well at certain stages, MDRs and MSPs fall short of delivering capabilities across your security operations, particularly as your organization matures to keep up with business transformation and growth. GreyMatter Open XDR Securityenables the best of both worlds—the right combination of technology—ours and yours, curated integrations and content wrapped with security expertise so your security professionals can focus on what’s most relevant for the business.
