Which version of Azure MFA is right for my organization?
Before you can decide where and how to deploy Multi-Factor Authentication (MFA), you need to answer three basic questions.
Each of the following sections provides details to help you answer the preceding questions.
What am I trying to secure?
To determine the correct two-step verification solution, first you must answer the question of what are you trying to secure with an additional factor of authentication. Is it an application that is in Azure? Or a remote access system? By determining what you are trying to secure, you can answer the question of where Multi-Factor Authentication needs to be enabled.
|What are you trying to secure||MFA in the cloud||MFA Server|
|First-party Microsoft apps||●||●|
|SaaS apps in the app gallery||●|
|Web applications published through Azure AD App Proxy||●|
|IIS applications not published through Azure AD App Proxy||●|
|Remote access such as VPN, RDG||●||●|
Where are the users located

|Azure AD and on-premises AD using Azure AD Connect - no password hash sync or pass-through authentication||●||●|
