## Overview

Every Entra Private Access (and Quick Access) application should be protected by an enabled Conditional Access policy that requires a managed device - either by targeting the application directly or via All cloud apps. This ensures private applications are only reachable from managed endpoints.

A policy satisfies the requirement when it grants **Require device to be marked as compliant** (Intune compliant) or **Require Microsoft Entra hybrid joined device** (`domainJoinedDevice`).

This check evaluates application coverage only; it does not evaluate whether the policy applies to every user of the app.

#### Remediation action

1. Sign in to the [Microsoft Entra admin center](https://entra.microsoft.com) as at least a **Conditional Access Administrator**.
2. Browse to **Entra ID** > **Conditional Access** > **Policies**.
3. Create or edit an enabled policy that targets the listed Private Access applications (or **All cloud apps**) and, under **Grant**, requires a **compliant** or **Microsoft Entra hybrid joined** device.
4. Set **Enable policy** to **On** and save.
