By Ross Anderson, Sophos BU executive at Duxbury NetworkingThat is the core value of Managed Detection and Response (MDR). Operating 24/7, MDR ensures swift and effective action whenever an incident arises, minimising risk and maintaining business continuity. It combines people, process, and technology to deliver continuous monitoring and a rapid, human-led response on behalf of the business. By incorporating MDR into their broader security strategy, resellers and their clients gain both speed and confidence. Just as importantly, MDR frees internal IT teams to focus on strategic projects and service delivery rather than constant firefighting.
