To remediate using the UI: 1. Navigate to the Microsoft Entra admin center https://entra.microsoft.com. 2. Expand Entra ID > Conditional Access and select Policies. 3. Create a new policy by selecting New policy. o Under Users or agents (Preview) include All users. o Under Target resources include All resources (formerly 'All cloud apps'). ▪ Under Exclude exclude any break-glass accounts. o Under Grant select Grant access. o Select the checkbox Require device to be marked as compliant. o Optionally, also select Require Microsoft Entra hybrid joined device if the organization uses hybrid joined devices. o Choose Require one of the selected controls. o Click Select at the bottom. 4. Under Enable policy set it to Report-only. 5. Click Create. 6. After allowing the policy to run in Report-only mode for at least one week, review the Sign-in logs for any unexpected impact, then return to the policy and set Enable policy to On. Note: Guest user accounts, if collaborating with the organization, should be considered when testing this policy.
