Difference Between SCEP and Windows Defender/Security Essentials

System Center Endpoint Protectoin (SCEP) and Windows Defender / Security Essentials are basically the same applications. The only difference is that SCEP is a enterprise supported application which allows for administrators to have granular control over settings so that the end user can not change them. Both Defender/Security Essentials and SCEP receive the same updates for definitions from Windows System Update Server.
