MDR
MDR is like hiring a security team without having a security team. Experts watch your systems 24/7 and respond to threats for you. Great for companies without dedicated security staff.
What is MDR?
Managed Detection and Response - outsourced cybersecurity service providing 24/7 threat monitoring, detection, and response.
Why Should You Care?
MDR directly addresses the "mean time to detect" and "mean time to respond" problems that plague organizations with limited in-house security resources. Without it, a breach can persist undetected for months, during which attackers exfiltrate sensitive data, move laterally through systems, or establish persistence mechanisms. For mid-market companies especially, the difference between a dedicated MDR catching an intrusion in hours versus discovering it from a third party can mean substantial avoided damages and regulatory penalties.
Is your business exposed?
Real-World Example
When a healthcare organization subscribes to an MDR service and a piece of malware begins moving through its network after hours, the MDR's SOC analysts detect the anomalous lateral movement in real time, immediately isolate the affected systems, and alert the client's IT team with forensic details—preventing the attacker from reaching patient databases. Without MDR, the same breach might go unnoticed until the next business day or until a compliance audit months later.
How to Protect Against MDR
- 1.
Evaluate MDR providers if lacking 24/7 coverage
- 2.
