# BitLocker Management for Enterprises

Companies that image their own computers using Microsoft System Center 2012 Configuration Manager SP1 (SCCM) or later can use an existing task sequence to [pre-provision BitLocker](https://technet.microsoft.com/library/hh846237.aspx#BKMK_PreProvisionBitLocker) encryption while in Windows Preinstallation Environment (WinPE) and can then [enable protection](https://technet.microsoft.com/library/hh846237.aspx#BKMK_EnableBitLocker). This can help ensure that computers are encrypted from the start, even before users receive them. As part of the imaging process, a company could also decide to use SCCM to pre-set any desired [BitLocker Group Policy](https://technet.microsoft.com/library/ee706521(v=ws.10).aspx).
Enterprises can use [Microsoft BitLocker Administration and Management (MBAM)](https://docs.microsoft.com/microsoft-desktop-optimization-pack/mbam-v25/) to manage client computers with BitLocker that are domain-joined on-premises until [mainstream support ends in July 2019](https://support.microsoft.com/en-us/lifecycle/search?alpha=Microsoft%20BitLocker%20Administration%20and%20Monitoring%202.5%20Service%20Pack%201) or they can receive extended support until July 2024. Thus, over the next few years, a good strategy for enterprises will be to plan and move to cloud-based management for BitLocker. When moving to cloud-based management, following these steps could be helpful:
1. Disable MBAM management and leave MBAM as only a database backup for the recovery key.
2. Join the computers to Azure Active Directory (Azure AD).
3. Use `Manage-bde -protectors -aadbackup` to backup the recovery key to Azure AD.
BitLocker recovery keys can be managed from Azure AD thereafter. The MBAM database does not need to be migrated.
Enterprises that choose to continue managing BitLocker on-premises after MBAM support ends can use the [BitLocker WMI provider class](https://msdn.microsoft.com/library/windows/desktop/aa376483) to create a custom management solution.
