Sophos Email Advanced: Push Encryption vs Portal Encryption

For internal email encryption to be properly implemented, the encryption needs to be done on the client, not on a server or gateway. The practicality of this depends on what the particpating clients (and users) can support, as in S/Mime is supported now by most mail clients, but not many users, or so it seems. If you don't want to be dependent on what recipients are running, you can install Central Device Encryption, right-click a file, and create a password protected file. You can mail the protected (html) file, and send the password via other means.
