Azure Active Directory (Azure AD) is a comprehensive identity and access management cloud solution which gives you a robust set of capabilities to manage users and groups. It helps secure access to on-premises and cloud applications, including Microsoft web services like Office 365 and many non-Microsoft software as a service (SaaS) applications.
Enable single sign-on to simplify user access to thousands of cloud applications from Windows, Mac, Android and iOS devices. Users can launch applications from a personalised web-based access panel or mobile app using their company credentials. Use the Azure AD Application Proxy module to go beyond SaaS applications and publish on-premises web applications to provide highly-secure remote access and single sign-on.
Azure Multi-Factor Authentication prevents unauthorised access to on-premises and cloud applications by providing an additional level of authentication. Protect your business and mitigate potential threats with security monitoring, alerts and machine learning-based reports that identify inconsistent access patterns.
Extend Active Directory and any other on-premises directories to Azure AD to enable single sign-on for all cloud-based applications. User attributes can be automatically synchronized to your cloud directory from all kinds of on-premises directories.
Every Azure customer has a free instance of Azure Active Directory to manage identities and access to all Azure services. You can use this cloud directory or create a new one to manage access to Office 365 and other SaaS applications.
