MDR (Managed Detection and Response)

A cybersecurity service where a third-party provider actively monitors, detects, and responds to security threats on behalf of an organisation. MDR services combine human expertise with automated tools to provide continuous threat protection.

Example: A small business without an in-house security team subscribes to an MDR service that continuously monitors its network and alerts the company when suspicious activity is detected.
