Azure Active Directory
Azure Active Directory is a comprehensive identity and access management cloud solution that provides a robust set of capabilities to manage users and groups and help secure access to applications including Microsoft online services like Office 365 and a world of non-Microsoft SaaS applications. Enable single sign-on to simplify user access to thousands of cloud applications from Windows, Mac and iOS devices. Users can launch cloud applications from a personalized web-based Access Panel (see image below) using their company credentials.
Azure Multi-Factor Authentication prevents unauthorized access to both on-premises and cloud applications by providing an additional level of authentication. Protect your business with security monitoring and alerts and machine learning-based reports that identify inconsistent access patterns to mitigate potential threats.
With Azure AD you can extend Active Directory and any other on-premises directories to Azure Active Directory for single sign on to all cloud-based applications. User attributes can be automatically synchronized to your cloud directory from all kinds of on-premises directories, with Dirsync or the newer AADSync.
