 Azure Monitor ensures that all data and saved queries are encrypted at rest using Microsoft-managed keys (MMK). You also have the option to encrypt data with your own key in [Azure Key Vault](../../key-vault/general/overview.md), with control over key lifecycle and ability to revoke  access to your data at any time. Azure Monitor use of encryption is identical to the way [Azure Storage encryption](../../storage/common/storage-service-encryption.md#about-azure-storage-service-side-encryption) operates.
 
-Customer-managed key is delivered on [dedicated clusters](./logs-dedicated-clusters.md) providing higher protection level and control. Data to dedicated clusters is encrypted twice, once at the service level using Microsoft-managed keys or Customer-managed keys, and once at the infrastructure level, using two different encryption algorithms and two different keys. [double encryption](../../storage/common/storage-service-encryption.md#doubly-encrypt-data-with-infrastructure-encryption) protects against a scenario where one of the encryption algorithms or keys may be compromised. In this case, the additional layer of encryption continues to protect your data. Dedicated cluster also allows you to protect your data with [Lockbox](#customer-lockbox-preview) control.
