Azure Active Directory Application Proxy is generally available.
Through an easy and secured process, the premium and basic modules allow on-premises web applications to be published via Azure Active Directory and made available to external users in the same way as software-as-a-service (SaaS) applications.
Single sign-in is available, in addition to user- and group-based access management. Internal apps appear alongside SaaS apps in end-user access panels (myapps).
