We're using Google Apps for Business. I'm researching various email encryption solutions. Our goal is to simply have all our outbound emails encrypted, every single email, regardless of where they're sent.
I've learned of some solutions & I'm noticing a pattern; in order to use encrypted emails, the recipient might have to click on a link to go through some verification process (unacceptable if this is for each individual email message), install some sort of software and/or certificate (not desired solution), or maybe do other things I'm not aware of yet.
So here's my question:
Are there any email encryption solutions that I can use with our Google Apps for Business platform that are plug-and-ply so to speak, that don't require the recipient of these encrypted emails to do anything special other than simply open the email that just arrived in their Inbox and instantly be able to read it?
