What is New in Windows Server 2012 R2 Active Directory?

• Join personal devices to the workplace : Windows Server 2012 R2 allows users to join their personal devices, both Windows devices and iOS devices, to Active Directory. When a personal device is Workplace-Joined, it will provide second-factor authentication and single sign-on (SSO) to corporate resources and applications.
• Provide users access to application and services from anywhere: Windows Server 2012 R2 includes a new Remote Access role service, called Web Application Proxy, which can be used to provide external access to application and services from anywhere.
• Managing risk with multi-factor access control and multi-factor authentication: Enabling users to join personal devices to the workplace and providing access to applications and services from anywhere comes with additional risks. Windows Server 2012 R2 includes enhancements to AD FS that are intended to manage these risks.
