Monitor BitLocker and device encryption
Intune provides a centralized location to identify the encryption status of your Windows 10 devices, and helps you access important information for BitLocker from your devices, as found in Azure Active Directory (Azure AD).
- The Encryption report (in Public Preview) provides details about a device’s encryption status and readiness. The report details can help you identify problems that prevent successful encryption of devices you want to protect.
- View BitLocker details (in Public Preview) like the Key ID and recovery keys for your devices from within the Intune portal.
You can use the Encryption report (in Public Preview) to view details about the Encryption status of your Windows 10 devices.
To find the report, Sign in to the Intune and go to Device Configuration, and then under Monitor, select Encryption report (Preview).
To appear in the Encryption report, a device must run Windows version 1607 or later.
The report displays the Device name for your Windows 10 devices and high-level details about each, including:
OS version – Version of Windows.
TPM version – The version of the Trusted Platform Module (TPM) chip on the device.
Encryption readiness – An evaluation of the devices readiness to support BitLocker encryption. Devices can be identified as:
Ready: The device can be encrypted by using MDM policy, which requires the device has a TPM and meets the following Windows 10 version and SKU requirements:
- Version 1703 or later, of Business, Enterprise, Education
- Version 1809 or later, of Pro
For more information, see the BitLocker configuration service provider (CSP) in the Windows documentation.
Not ready: The device doesn't have full encryption capabilities, but still supports encryption. For example, the device might be encrypted manually by a user, or through Group Policy that can be set to allow encrypting without a TMP.
Not applicable: There is not enough information to classify this device.
Encryption status – Whether the OS drive is encrypted.
Device encryption status
When you select a device, Intune displays the Device encryption status pane.
This pane provides the following details:
Device name – The name of the device you're viewing.
Encryption readiness - An evaluation of the devices readiness to support BitLocker encryption. A device could have an Encryption status of Encrypted even though its Encryption readiness is Not ready, because it lacks a TPM. (See Encryption readiness in he preceding section for more details.)
Encryption status - Whether the OS drive is encrypted.
Profiles – A list of the Device configuration profiles that apply to this device and include the following Profile type and settings:
- Profile type = Endpoint protection
- Settings > Windows Encryption > Encrypt devices = Required
This list can be of use in locating individual policies for review should the Profile state summary indicate problems.
Profile state summary – A summary of the profiles that apply to this device. The summary represents the least favorable condition across all applicable profiles. For example, if one profile results in an Error, the Profile state summary will display Error.
Status details – Advanced details about the device’s encryption state.
Intune only shows Status details for devices that run the Windows 10 April 2019 Update or later.
This field displays information for each applicable error that can be detected. You can use this information to understand why a device might not be encryption ready.
The following are examples of the status details Intune can report:
- The BitLocker policy requires user consent to launch the BitLocker Drive Encryption Wizard to start encryption of the OS volume but the user didn't consent.
- The encryption method of the OS volume doesn't match the BitLocker policy.
- The policy BitLocker requires a TPM protector to protect the OS volume, but a TPM isn't used.
- The BitLocker policy requires a TPM-only protector for the OS volume, but TPM protection isn't used.
- The BitLocker policy requires TPM+PIN protection for the OS volume, but a TPM+PIN protector isn't used.
- The BitLocker policy requires TPM+startup key protection for the OS volume, but a TPM+startup key protector isn't used.
- The BitLocker policy requires TPM+PIN+startup key protection for the OS volume, but a TPM+PIN+startup key protector isn't used.
- The OS volume is unprotected.
- Recovery key backup failed.
- A fixed drive is unprotected.
- The encryption method of the fixed drive doesn't match the BitLocker policy.
- To encrypt drives, the BitLocker policy requires either the user to sign in as an Administrator or, if the device is joined to Azure AD, the AllowStandardUserEncryption policy must be set to 1.
- Windows Recovery Environment (WinRE) isn't configured.
- A TPM isn't available for BitLocker, either because it isn't present, it has been made unavailable in the Registry, or the OS is on a removeable drive.
- The TPM isn't ready for BitLocker.
- The network isn't available, which is required for recovery key backup.
BitLocker recovery keys
As a Public Preview, Intune provides access the Azure AD blade for BitLocker so you can view BitLocker Key IDs and recovery keys for your Windows 10 devices, from within the Intune portal. To be accessible, the device must have its keys escrowed to Azure AD.
- Sign in to Intune, go to Devices and then under Manage, select All devices.
- Select a device from the list, and then under Monitor, select Recovery keys – Preview.
When keys are available in Azure AD, the following information is available:
- BitLocker Key ID
- BitLocker Recovery Key
- Drive Type
When keys aren't in Azure AD, Intune will display No BitLocker key found for this device.
Information for BitLocker is obtained using the BitLocker configuration service provider (CSP). BitLocker CSP is supported on Windows 10 version 1703 and later, and for Windows 10 Pro version 1809 and later.
Create a device compliance policy for Windows 10 devices to configure BitLocker and encryption.
