Confidential Computing

ELI5 - The Vibe Check

Normally, data is encrypted sitting on disk and encrypted flying across the network, but the moment your program actually uses it in memory, it's sitting there in plain text, visible to anyone with enough access to the machine. Confidential computing closes that last gap using special hardware that keeps data encrypted even while it's being processed, inside a sealed vault that not even the cloud provider running the hardware can peek into.

Real Talk

Confidential computing protects data in use by performing computation inside a hardware-based trusted execution environment (TEE), such as Intel SGX, AMD SEV, or AWS Nitro Enclaves, which encrypts memory and isolates the workload from the host operating system, hypervisor, and cloud provider itself. It complements encryption at rest and in transit, closing the remaining gap in the data lifecycle, and is used for scenarios like multi-party data collaboration and regulated workloads where even the infrastructure operator must be excluded from trust.
