The main difference between MDR and Endpoint Detection Response (EDR) is that MDR is a managed service while EDR is an on-prem or cloud solution. EDR provides value by delivering visibility into endpoint activity and allowing infosec teams to detect malicious behavior before it can cause damage. MDR takes this technology further by providing 24/7 monitoring and response service from a team of highly qualified security analysts. These experts are constantly monitoring and responding to incidents so your organization can focus on larger projects.
