What is XDR? Extended Detection and Response explained

Extended Detection and Response (XDR) is a detection platform that correlates telemetry from endpoint, identity, email, cloud and network in one data model. XDR replaces many functions of a classic SIEM, but it does not replace a team. Only combined with a SOC or MDR does it turn into security.

How this compares to neighbouring topics

This page defines XDR as a platform. For the difference between a platform and a team, read SOC vs. SIEM. For MDR as a service, see What is MDR. For the fundamentals of the operating unit, read What is a SOC. As a full offering, SOC as a Service Switzerland covers platform, team and response together.

Short definition

XDR unifies telemetry from endpoint, identity, email, cloud and network in a single data model. It correlates events across system boundaries and bundles individual alerts into prioritised cases. Native XDR comes from one vendor; Open XDR integrates telemetry from multiple vendors.

The short version

XDR is a modern replacement for many SIEM functions, not a replacement for the team.

XDR vs. SIEM vs. EDR

Criterion	EDR	SIEM	XDR
Data sources	Endpoint only	All logs, generic	Endpoint, identity, cloud, email, network
Correlation	Within endpoint	Rule-based, high maintenance	Model-based, cross-source
Response capability	Endpoint isolation	None, alerts only	Response on endpoint and identity
Operating without a team	Little value	No value	No value

What XDR delivers

Fewer alerts through cross-source correlation
Cases instead of raw alerts, prioritised by impact
Shorter investigations thanks to pre-joined context
Response actions directly from the platform (endpoint, identity)
Lower SIEM licence and storage cost with the right architecture

XDR in Switzerland

Swiss customers increasingly retire legacy SIEM in favour of XDR plus a data lake, often combined with a managed SOC. The critical question stays the same: who works the cases every day. Without a team, XDR is an expensive console. If you do not run it in-house, combine the platform with SOC as a Service Switzerland or consume MDR as an outcome service.

Frequently asked questions

Is XDR just a better EDR?

No. EDR sees endpoint; XDR correlates endpoint with identity, cloud, email and network in one data model.

Does XDR fully replace a SIEM?

Often yes for detection and response, often not for compliance logging and long-term retention. Many customers pair XDR with a data lake.

What is the difference between native and open XDR?

Native XDR uses one vendor's telemetry and response; open XDR integrates sources from multiple vendors. Native goes live faster; open is more flexible when a stack already exists.

Do I still need a SOC alongside XDR?

Yes. XDR produces cases, but someone has to work them. Without a SOC or MDR the platform stays unused.

What does XDR cost in Switzerland?

Cost depends on endpoint count, integrated sources, data volume and the vendor's licence model. Team operating cost is separate unless you consume managed SOC.

What is MDR? Managed Detection and Response explained

Managed Detection and Response (MDR) is the common name for a service that detects attacks, investigates them and responds, including isolating compromised systems. MDR is neither a tool nor a platform, but a contract with defined response duties. At ANOMAL, this service is part of SOC as a Service.

SOC, SIEM, EDR, XDR, MDR: the terms explained

SOC is the function; SIEM, EDR and XDR are tools; MDR is a service. The label matters less than whether response happens and in whose mandate. At ANOMAL, SOC as a Service covers detection and response and is often called MDR; a managed SIEM is part of the SOC with analysts and response in the mandate. Customers keep their existing tools.

SOC as a Service in Switzerland: The Complete Guide

SOC as a Service is an externally operated Security Operations Center that monitors your environment around the clock, detects attacks and triggers the response. According to Mandiant M-Trends 2026, attackers went undetected for a median of 14 days in 2025. With a SOC that detects and assesses around the clock, typical detection time becomes much shorter.

What is a SOC? Definition, tasks and structure

A Security Operations Center (SOC) is a team of people, processes and technology. It monitors an organisation's IT and OT environment around the clock, detects attacks and coordinates the response. A SOC is not a piece of software; it is an operating unit.
