You can use Azure Active Directory (Azure AD) conditional access policies to apply access rules to any Azure AD–connected application, such as Office 365, Salesforce.com, Box, ServiceNow, and other SaaS and custom or on-premises web applications. More-sensitive apps can be assigned stricter policies for all or specific groups of users, such as requiring Azure Multi-Factor Authentication or even blocking access outside the corporate network, while less-sensitive apps can have policies that are more open. Conditional access policies are available through Azure AD Premium.
