App attestation is a security mechanism that allows a user's device to securely verify the identity and configuration of a private cloud compute cluster before sending any requests. This process involves establishing an end-to-end encrypted connection between the user's device and the private cloud compute cluster. Only the chosen cluster can decrypt the request data, ensuring that the data is not retained after the response is returned and is never accessible to Apple.
