ProtonMail is the most well known encrypted email service in Switzerland, and perhaps the world. It began as a crowdfunded project initiated by a team of researchers at CERN, growing into the full-fledged email service it is today. Like we mentioned earlier, we love ProtonMail and their contribution to the browser-based encryption library, OpenPGP.js. What fewer people know though is that it’s possible to host your own email server in Switzerland – and use OpenPGP and/or S/MIME to exchange encrypted email.
