What is Managed Detection and Response in Cybersecurity?
A service category where a provider operates detection and response capabilities on behalf of the customer, including 24/7 monitoring, alert triage, threat hunting, and incident response. MDR providers use their own technology stack or manage the customer's tools. Unlike traditional MSSPs that focus on monitoring and alerting, MDR services take response actions and provide expert investigation.
Why Managed Detection and Response Matters for Your Cybersecurity Career
Many organizations cannot staff a 24/7 SOC. MDR services provide enterprise-grade detection and response at a fraction of the cost. Security leaders evaluate MDR as an alternative to building internal capabilities. Understanding the MDR market helps cybersecurity professionals advise organizations on build-vs-buy decisions for security operations. MDR providers also hire experienced analysts.
