A company wants to enable employees to securely access on-premises applications without needing a VPN. Which Microsoft Entra feature should they implement?
Azure AD Application Proxy provides secure remote access to on-premises web applications for internal users without requiring a VPN or opening inbound firewall ports. It acts as a reverse proxy, publishing internal applications through Azure AD, allowing employees to authenticate with their Azure AD credentials. This solution enables seamless and secure access to corporate resources from any location, making it the ideal choice for the scenario described.
Why this answer
Microsoft Entra Application Proxy provides secure remote access to on-premises web applications by acting as a reverse proxy. It eliminates the need for a VPN by routing user traffic through the Entra ID service, which authenticates the user and then establishes a secure outbound connection to the on-premises application connector. This allows employees to access internal apps from anywhere using the same credentials and conditional access policies.
Exam trap
The trap here is that candidates often confuse Application Proxy with a VPN or assume that B2B Collaboration is needed for remote access, but the key differentiator is that Application Proxy is specifically designed for secure, VPN-less access to on-premises web apps through a reverse proxy architecture.
How to eliminate wrong answers
Option A is wrong because Identity Protection is a risk-based detection and remediation tool that identifies compromised identities and suspicious sign-ins, not a remote access solution for on-premises applications. Option B is wrong because B2B Collaboration enables external users (partners, vendors) to access your organization's resources using their own identities, but it does not provide a reverse proxy or secure channel to on-premises apps. Option D is wrong because Privileged Identity Management (PIM) manages just-in-time and time-bound access to privileged roles in Azure AD and Azure resources, not general remote access to on-premises applications.
