Hi @Awan
SPICE is designed with security as a top priority, incorporating several measures to ensure that stored data remains well-protected. To address security concerns, SPICE uses AWS KMS for encryption, and there is also the option to use customer-managed keys, offering an additional level of control over the encryption process.
Please refer the below QuickSight documentation and community post this might be helpful for you.
It might be helpful to provide the client with information from Amazon’s official documentation regarding the encryption and security of SPICE datasets to help.
Hope this helps!
