Frequently Asked Questions

Deployment

“Can CCF run without a Trusted Execution Environment (TEE)?”

CCF can be run on any x86 CPU without a TEE in Insecure Virtual mode. However, this mode does not provide any security guarantees (e.g. no memory encryption and no remote attestation) and should not be used for production deployments.

Tip

The Insecure Virtual mode may be useful for development when access to TEE-enabled hardware is limited (e.g. continuous integration pipelines).

“Can CCF run on-prem rather than in Azure?”

CCF itself can run on prem as well as in Azure. However, for the TEE security guarantees to be trusted by clients and operators, the deployment environment should have access to the endorsements of the TEE attestation reports.
