Confidential computing definition
Confidential computing is a privacy and security-focused technology that protects data while it’s being used — not just when it's stored or transmitted. It uses special hardware to create a secure, isolated area in a computer’s processor where sensitive data can be processed without being exposed. This means your data stays private and secure even when it's being worked on.

How does confidential computing work?
- The processor sets up a protected zone called an "enclave" where sensitive data can be used.
- This enclave is isolated from the rest of the system, meaning other programs and users can’t access the data inside it.
- Data inside the enclave is encrypted, keeping it safe from unauthorized access, even if someone manages to break into other parts of the system.
- The computer processes the data within this secure enclave, keeping it protected throughout its use.
When to use confidential computing
- When handling sensitive information — financial records, personal health data, or confidential business documents.
- When you’re processing data in the cloud and want to make sure that even the cloud provider can't access your data.
- When multiple parties need to process data without exposing their individual datasets to each other.
- To meet strict data protection regulations and standards that require secure data handling.
