@Doug Smith - Hi Doug,

We are very security-aware. No backups ever pass or are held on our servers. All backups are stored either on your server or the backup destination that you provide.

For communication with your WordPress site, ManageWP uses OpenSSL encrypted protocal which is far more secure then the current industry standard (XML-RPC).

Finally, if you want to run ManageWP form your server, we also offer the self-hosted version.
