Azure Active Directory
Seamless, secure identity and access management
Identity, security, and productivity all at once
Azure Active Directory (Azure AD) helps you manage user identities and create intelligence-driven access policies to secure your resources. As an integral component of Office 365, Azure and Enterprise Mobility + Security, Azure AD centralizes identity and access management to enable deep security, productivity, and management across devices, data, apps, and infrastructure. Azure AD is built to work for apps in the cloud, on mobile, or on-premises, and you can layer security features such as conditional access to help protect users and your business.

Get seamless access to any application from virtually any location or device
By using one identity, users can launch all of their cloud applications from a personalized, web-based access panel or mobile app and have the same experience whether they’re working on Windows, Mac, Android, or iOS devices. With the Azure AD Application Proxy, you can go beyond cloud applications and publish on-premises web applications to provide highly secure remote access and single sign-on.

"Historically, employees were not eager for Multi-Factor Authentication. But since we moved to Enterprise Mobility + Security and added single sign-on and conditional access, they found it really easy to use. Conditional access simplifies MFA because it kicks in only when needed." 
"By providing access to multiple resources with just one set of credentials, G&J Pepsi made life orders of magnitude easier for workers and IT staff alike."
"St. Luke's uses Azure Active Directory Premium to manage employee access to on-premises applications and software-as-a-service apps."
"Azure Active Directory Premium makes life simpler for the business and for employees. It gives them access to enterprise applications from any device with a single sign-on that is secure and reliable. That is fundamental in increasing the adoption of cloud technology."
"We give them a username and password, and they're able to reset their own passwords through Azure Active Directory. This is important, because we have such a small IT staff."
"Without Azure Active Directory integrated with our 2,100 customers' AD databases, we simply could not manage all the passwords and logon activities of the many hundreds of thousands of teachers and students who make up our customer base."
"The company will be deploying the Enterprise Mobility Suite for three cloud-based services—Microsoft Azure Active Directory Premium, Microsoft Intune, and Azure Rights Management—for user identity and access management, mobile device management, and file and data protection capabilities."
Azure Active Directory supports thousands of preintegrated SaaS apps for single sign-on
