Azure Active Directory's Application Proxy provides secure remote access to on-premises web applications. After a single sign-on to Azure AD, users can access both cloud and on-premises applications through an external URL or an internal application portal. For example, Application Proxy can provide remote access and single sign-on to Remote Desktop, SharePoint, Teams, Tableau, Qlik, and line of business (LOB) applications.
Azure AD Application Proxy is:
Simple to use. Users can access your on-premises applications the same way they access Microsoft 365 and other SaaS apps integrated with Azure AD. You don't need to change or update your applications to work with Application Proxy.
Secure. On-premises applications can use Azure's authorization controls and security analytics. For example, on-premises applications can use Conditional Access and two-step verification. Application Proxy doesn't require you to open inbound connections through your firewall.
Cost-effective. On-premises solutions typically require you to set up and maintain demilitarized zones (DMZs), edge servers, or other complex infrastructures. Application Proxy runs in the cloud, which makes it easy to use. To use Application Proxy, you don't need to change the network infrastructure or install additional appliances in your on-premises environment.
