Managed XDR (MXDR) is a service-led security solution that uses a wide range of telemetry sources to better unify and automate incident investigation, analysis, and response. Extended Detection and Response (XDR) is the technology at the heart of MXDR. It is a security platform that unifies telemetry across multiple security layers, such as networks, endpoints, applications, email, identities, and cloud services, into a single platform.
