 # What is Azure Active Directory?
 
-Azure Active Directory (Azure AD) is a cloud-based identity and access management service. This service helps your employees access external resources, such as Microsoft 365, the Azure portal, and thousands of other SaaS applications. Azure AD also helps them access internal resources. These are resources like apps on your corporate network and intranet, along with any cloud apps developed by your own organization. For more information about creating a tenant for your organization, see [Quickstart: Create a new tenant in Azure Active Directory](active-directory-access-create-new-tenant.md).
