Thanks for noting this. A lot of discussion about email encryption and security is clearly from the consumer POV, and most people seem to be unaware of things enterprises already do (using commonly available tools & settings) to secure email. Not that it replaces message encryption via S/MIME or PGP, but companies like https://www.mailvelope.com/ and https://www.virtru.com are trying to help with that.
