Require MFA

CIS - High/Medium sign-in risk

Require MFA · Sign-in frequency enforced

About this policy

The CIS - High_Medium sign-in risk policy requires MFA for all users when Entra ID Protection detects a high or medium sign-in risk level. Unlike the block variant, this policy challenges the user rather than denying access outright, allowing a legitimate user to verify their identity and continue. It covers all cloud apps and complements your other risk-based policies by providing a proportionate response to suspicious sign-in behaviour.

Policy conditions

Users: All users
Apps: All cloud apps
Risk: Sign-in risk: high, medium
