    Hi Robert,

    In my point of view, it depends on the use case of a particular scenario. I understand that implementing both client-side AND server-side encryption might be an overkill. However, for financial applications or sensitive government data, implementing strict security measures and encryption is suitable.

    Client-side encryption is preferable if you want the data encryption/decryption process is all done on the client-side and to ensure that the private encryption keys never leave your application for compliance purposes. And since the data is already encrypted before you send it to Amazon S3 (via a public Internet connection / VPN) it also acts as an encryption in transit against packet sniffing.

    It’s also suitable for cases where you have to ensure that the data are encrypted at rest using an encryption key that is both provided and managed by your company.
