# Require device compliance with Conditional Access
Microsoft Intune and Microsoft Entra work together to secure your organization through [device compliance policies](/mem/intune/protect/device-compliance-get-started) and Conditional Access. Device compliance policies are a great way to ensure user devices meet minimum configuration requirements. The requirements can be enforced when users access services protected with Conditional Access policies.
Some organizations might not be ready to require device compliance for all users. These organizations might instead choose to deploy the following policies:
- [Require compliant or Microsoft Entra hybrid joined device for their administrators](policy-alt-admin-device-compliand-hybrid.md)
- [Require a compliant device, Microsoft Entra hybrid joined device, **OR** multifactor authentication for all users](policy-alt-all-users-compliant-hybrid-or-mfa.md)
- [Block unknown or unsupported device platforms](policy-all-users-device-unknown-unsupported.md)
- [Disable browser persistence](policy-all-users-persistent-browser.md)
On iOS, Android, macOS, and some non-Microsoft web browsers, Microsoft Entra ID identifies the device using a client certificate that is provisioned when the device is registered with Microsoft Entra ID. When a user first signs in through the browser the user is prompted to select the certificate. The end user must select this certificate before they can continue to use the browser.
#### Subscription activation
Organizations that use the [Subscription Activation](/windows/deployment/windows-10-subscription-activation) feature to enable users to "step-up" from one version of Windows to another, might want to exclude the Windows Store for Business, AppID 45a330b1-b1ec-4cc1-9161-9f03992aa49f from their device compliance policy.

### B2B scenarios
For organizations you have a relationship with and trust, you might trust their device compliance claims. To configure this setting, see the article [Manage cross-tenant access settings for B2B collaboration](../../external-id/cross-tenant-access-settings-b2b-collaboration.yml#to-change-inbound-trust-settings-for-mfa-and-device-claims).
