Do they offer end-to-end encryption? If they use ZFS I assume they should have checksums that detect data corruption.

well kind of yes I guess, protocols to transfer from your side to C14 platform is fully encrypted (SSH/FTPS ...) then it's encrypted by the C14 platform itself to the end-storage backends

I've been primarily concerned if they store data encrypted at rest, with my own key.

[mikmak]

yes every bit is encrypted with AES-256-CBC, we provide the encryption key which you must keep to restore
