Microsoft Defender App

To integrate with Microsoft Defender, users will have to authorize Leen’s Microsoft Defender app, which is an OAuth2 app. This will allow Leen to access the appropriate Microsoft Defender resources in the organization’s account. Leen takes care of the OAuth2 code-flow and access token management, so you don’t have to worry about it.
