MDR: Managed Detection and Response in Cybersecurity
MDR stands for Managed Detection and Response. MDR is a managed service where a third-party provider monitors an organization's environment, detects threats, and responds to incidents on their behalf. MDR providers staff 24/7 SOC teams and use their own tooling and threat intelligence.
How MDR Is Used in Cybersecurity
Organizations without a full in-house SOC contract MDR providers to maintain continuous threat monitoring. Security leaders evaluate MDR vendors based on response SLAs, coverage scope, and integration with existing tools. GRC analysts verify that MDR service agreements meet compliance requirements for incident detection timelines.
