A year ago Microsoft announced that they work working on a new technology in Azure to protect and encrypt data in use, called Azure Confidential Computing. If you are moving sensitive data to the cloud, you also want to encrypt it. Today, you can do this for data in transit and data at rest, however data in use is a challenge. Azure Confidential Computing addresses exactly that scenario, and helps you to encrypt data in use. Microsoft was running a private preview program in the last year, and at Microsoft Ignite this year, Microsoft opened up a public preview.
What is Azure Confidential Computing
Azure Confidential Computing together with Intel SGX technology addresses the following threads:
Malicious insiders with administrative privilege or direct access to hardware on which it is being processed
Hackers and malware that exploit bugs in the operating system, application, or hypervisor
