MDR

Managed Detection and Response

Definition

Managed Detection and Response is a cybersecurity service that combines technology and human expertise to perform threat hunting, monitoring, and response to detected threats, going beyond traditional alert-based monitoring.

Buyer context

MDR usually means the provider investigates alerts and gives more context than basic monitoring. The important buying difference is response authority: some MDR services advise your team, while others can isolate hosts, disable accounts, or contain threats directly under agreed playbooks.
