## Content

An MXDR provider may collect and correlate evidence from endpoints, identities, email, networks, cloud services, and applications, then add analysts and operational processes for monitoring, threat hunting, investigation, guidance, and authorized response.

There is no standard feature set behind the name. Some services operate one provider’s XDR platform; others integrate customer tools through a SIEM, data platform, or multiple detection products. Buyers should define which data sources, environments, and response actions are actually included, who maintains integrations and detection logic, and whether service personnel may contain an incident directly or only recommend action.

### Key points

- **Coverage definition:** List supported assets, telemetry, retention, integrations, monitoring hours, languages, threat-hunting scope, and gaps created by unsupported systems or licensing.
- **Operating model:** Assign responsibility for triage, investigation, containment, eradication, recovery support, detection tuning, and communication during both customer and provider incidents.
- **Response authority:** Pre-authorize safe actions where appropriate, require approval for disruptive steps, preserve decision logs and test the joint workflow before a real incident.
- **Important limitation:** MXDR is a market category, not a guarantee of broad visibility or effective response. Correlation cannot compensate for missing telemetry, weak integrations, unclear ownership, or a provider’s inability to act.
