Azure Disk Encryption uses the industry-standard [DM-Crypt](https://en.wikipedia.org/wiki/Dm-crypt) feature of Linux and the [BitLocker](/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc732774(v=ws.11)) feature of Windows to provide volume encryption for the OS and the data disks. The solution is integrated with [Azure Key Vault](/azure/key-vault/) to help you control and manage the disk-encryption keys and secrets in your key vault subscription. The solution also ensures that all data on the virtual machine disks are encrypted at rest in Azure Storage.
