Microsoft's Azure Active Directory (Azure AD) is a cloud-based authentication and authorization service. It weaves application access management, core directory services, and identity protection into a single solution. It enables all employees in an organization to sign in and access resources in the following areas:
i) External resources such as Microsoft 365, the Azure gateway, and millions of other SaaS services.
ii) Internal resources, such as apps on your company's intranet and network and any cloud service apps built by your company.
