Monitor device encryption with Intune

The Microsoft Intune encryption report is a centralized location to view details about a device's encryption status and find options to manage device recovery keys. The recovery key options that are available depend on the type of device you're viewing.

Tip

To configure Intune policies to manage encryption on devices, see:

To find the report, Sign in to the Microsoft Intune admin center. Select Devices > Manage devices > Configuration, select the Monitor* tab, and then select Device encryption status.

View encryption details

The encryption report shows common details across the supported devices you manage. The following sections provide details about the information that Intune presents in the report.

Prerequisites

The encryption report supports reporting on devices that run the following operating system versions:

  • macOS 10.13 or later
  • Windows version 1607 or later

Report details

The Encryption report pane displays a list of the devices you manage with high-level details about those devices. You can select a device from the list to drill-in and view more details from the devices Device encryption status pane.

  • Device name - The name of the device.

  • OS – The device platform, such as Windows or macOS.

  • OS version – The version of Windows or macOS on the device.

  • TPM version (applies to Windows 10/11 only) – The version of the Trusted Platform Module (TPM) chip detected on the Windows device.

    For more information on how we query the TPM version, see DeviceStatus CSP - TPM Specification.

  • Encryption readiness – An evaluation of the devices readiness to support an applicable encryption technology, like BitLocker or FileVault encryption. Devices are identified as:

    • Ready: The device can be encrypted by using MDM policy, which requires the device meet the following requirements:

      For macOS devices:

      • macOS version 10.13 or later

      For Windows devices:

      • Windows 10 version 1709 or later of Business, Enterprise, Education, Windows 10 version 1809 or later of Pro, and Windows 11.
      • The device must have a TPM chip

      For more information on Windows prerequisites for encryption, see the BitLocker configuration service provider (CSP) in the Windows documentation.

    • Not ready: The device doesn't have full encryption capabilities, but might still support encryption.

    • Not applicable: There isn't enough information to classify this device.

  • Encryption status – Whether the OS drive is encrypted.

  • User Principal Name - The primary user of the device.

Device encryption status

When you select a device from the Encryption report, 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 device's readiness to support encryption through the MDM policy based on an activated TPM.

    When a Windows 10/11 device has a readiness of Not ready, it might still support encryption. To have the Ready designation, the Windows device must have a TPM chip activated. However, TPM chips aren't required to support encryption, as the device can still be manually encrypted. or through a MDM/Group Policy setting that can be set to allow encrypting without a TPM.

  • Encryption status - Whether the OS drive is encrypted. It can take up to 24 hours for Intune to report on a device's encryption status or a change to that status. This time includes time for the OS to encrypt, plus time for the device to report back to Intune.

    To speed up the reporting of FileVault encryption status before device check-in normally occurs, have users sync their devices after encryption completes.

    For Windows devices, this field doesn't look at whether other drives, such as fixed drives, are encrypted. Encryption status is coming from DeviceStatus CSP - DeviceStatus/Compliance/EncryptionCompliance.

  • Profiles – A list of the Device configuration profiles that apply to this device and are configured with the following values:

    • macOS:

      • Profile type = Endpoint protection
      • Settings > FileVault > FileVault = Enable
    • Windows 10/11:

      • Profile type = Endpoint protection
      • Settings > Windows Encryption > Encrypt devices = Require

    You can use the list of profiles to identify 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 the applicable profiles. For example, if only one out of several applicable profiles results in an error, the Profile state summary displays Error.

    To view more details of a status in the Intune admin center, go to Devices > Manage devices > Configuration > select the profile. Optionally, select Device status and then select a device.

  • Status details – Advanced details about the device's encryption state.

    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:

    macOS:

    • The recovery key hasn't been retrieved and stored yet. Most likely, the device hasn't been unlocked, or it hasn't checked in.

      Consider: This result doesn't necessarily represent an error condition but a temporary state that could be because of timing on the device where escrow for recovery keys must be set up before the encryption request is sent to the device. This status might also indicate the device remains locked or hasn't checked in with Intune recently. Finally, because FileVault encryption doesn't start until a device is plugged in (charging), it's possible for a user to receive a recovery key for a device that isn't yet encrypted.

    • The user is deferring encryption or is currently in the process of encryption.

      Consider: Either the user hasn't yet logged out after receiving the encryption request, which is necessary before FileVault can encrypt the device, or the user has manually decrypted the device. Intune can't prevent a user from decrypting their device.

    • The device is already encrypted. Device user must decrypt the device to continue.

      Consider: Intune can't set up FileVault on a device that is already encrypted. However, after a device receives policy to enable FileVault, a user can upload their personal recovery key to enable Intune to then manage encryption on that device. Alternately, the user can manually decrypt their device so it can then be encrypted by Intune policy at a later time. However, we don't recommend manual decryption as doing so can leave a device unencrypted for a time.

    • FileVault needs the user to approve their management profile in macOS Catalina and higher.

      Consider: Beginning with macOS version 10.15 (Catalina), user approved enrollment settings can result in the requirement that users manually approve FileVault encryption. For more information, see User Approved enrollment in the Intune documentation.

    • Unknown.

      Consider: One possible cause for an unknown status is that the device is locked and Intune can't start the escrow or encryption process. After the device is unlocked, progress can continue.

    Windows 10/11:

    For Windows devices, Intune only shows Status details for devices that run the Windows 10 April 2019 Update or later, or Windows 11. Status details are coming from BitLocker CSP - Status/DeviceEncryptionStatus.

    • 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.

      Consider: A BitLocker policy to encrypt OS drives was applied on the machine but encryption was suspended or didn't complete for the OS drive.

    • Recovery key backup failed.

      Consider: Check the devices Event log to see why the recovery key backup failed. You might need to run the manage-bde command to manually escrow recovery keys.

    • A fixed drive is unprotected.

      Consider: A BitLocker policy to encrypt fixed drives was applied on the machine but encryption was suspended or didn't complete for the fixed drive.

    • 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 Microsoft Entra ID, the AllowStandardUserEncryption policy must be set to 1.

    • Windows Recovery Environment (WinRE) isn't configured.

      Consider: Need to run command line to configure the WinRE on separate partition; as that wasn't detected. For more information, see REAgentC command-line options.

    • A TPM isn't available for BitLocker, either because it isn't present, it's been made unavailable in the Registry, or the OS is on a removable drive.

      Consider: The BitLocker policy applied to this device requires a TPM, but on this device, the BitLocker CSP detects that the TPM might be disabled at the BIOS level.

    • The TPM isn't ready for BitLocker.

      Consider: The BitLocker CSP sees that this device has an available TPM, but the TPM might need to be initialized. Consider running intialize-tpm on the machine to initialize the TPM.

    • The network isn't available, which is required for recovery key backup.

Export report details

While viewing the Encryption report pane, you can select Export to create a .csv file download of the report details. This report includes the high-level details from the Encryption report pane and Device encryption status details for each device you manage.

Export details

This report can be of use in identifying problems for groups of devices. For example, you might use the report to identify a list of macOS devices that all report FileVault is already enabled by the user, which indicates devices that must be manually decrypted before Intune can manage their FileVault settings.
