If you have spent any time in Azure Active Directory, chances are you have stumbled across Azure AD Conditional Access. It is at the very center of Microsoft Zero Trust. At its most basic, it evaluates every sign in to your Azure AD tenant. It takes the different signals that form that sign in. The location a user is coming from, the health of a device. It can look at the roles a user has, or the groups they are in. Even what application is being used to sign in.
