ProtonMail:终端到终端加密邮件平台是一个由麻省理工学院创业指导下开发的一款终端到终端的加密电子邮件系统，总部在瑞士，并基于瑞士隐私法保护邮件的隐私，对于安全基本要求很高的用户来说，非常有用。
安全邮件的问题这几年被提到的很多，尤其是政府、部队方面对安全邮件的需求还是很旺盛的。ProtonMail提供端对端的邮件加密方案，并且宣布永久免费。
ProtonMail was founded in summer 2013 at CERN by scientists who were drawn together by a shared vision of a more secure and private Internet. Early ProtonMail hackathons were held at the famous CERN Restaurant One. ProtonMail is developed both at CERN and MIT and is headquartered in Geneva, Switzerland. We were semifinalists in 2014 MIT 100K startup launch competition and are advised by the MIT Venture Mentoring Service.
