Azure confidential computing

Protect your data and code while they’re in use in the cloud.

  • Safeguard data from malicious and insider threats while it’s in use
  • Maintain control of data throughout its lifetime
  • Protect and validate the integrity of code in the cloud
  • Ensure that data and code remain outside the view of the cloud platform provider

Take data security to the next level with confidential computing

What is confidential computing?

Security is a key driver accelerating the adoption of cloud computing, but it’s also a major concern when you’re moving extremely sensitive IP and data scenarios to the cloud.

Confidential computing is the protection of data-in-use through isolating computations to a hardware-based trusted execution environment (TEE). While data is traditionally encrypted at rest and in transit, confidential computing protects your data while it’s being processed. A TEE provides a protected container by securing a portion of the hardware’s processor and memory. You can run software on top of the protected environment to shield portions of your code and data from view or modification from outside of the TEE.


"Customers are demanding the capability to reduce the attack surface and help protect sensitive data in the cloud by encrypting data in use. Our collaboration with Microsoft brings enterprise-ready confidential computing solutions to market, and enables customers to take greater advantage of the benefits of cloud and multi-party compute paradigms using Intel® SGX technology."

Core components of confidential computing

Azure is making confidential computing a reality with innovation across hardware, software, and services.

Hardware and compute

Deploy and manage compute instances that are enabled with TEEs

Use the new DCsv2-series virtual machines on Azure to build on top of the latest generation of Intel Xeon processors with [Intel] SGX technology in a completely virtualized cloud-based environment. The VMs allow you to run and build applications that protect your code and data while it’s in use.


Develop against a standard enclaving abstraction

Take advantage of enclave creation and management, system primitives, runtime support, and cryptographic library support. The Open Enclave SDK (OE SDK) project provides a consistent API surface around an enclaving abstraction, supporting portability across enclave types and flexibility in architecture. Build portable C/C++ applications against different enclave types. Learn more about developing with the OE SDK on Azure confidential computing VMs.


Verify the identity of TEEs and the code running inside them

Validate code identity to determine whether to release secrets. Verification is simple and highly available with attestation services.


Gain insights from Microsoft Research to harden your enclave code

Explore research on new applications for confidential computing, techniques to harden TEE applications, and tips to prevent unauthorized access from outside the TEE.
