ProtonMail:終端到終端加密郵件平臺是一個由麻省理工學(xué)院創(chuàng)業(yè)指導(dǎo)下開發(fā)的一款終端到終端的加密電子郵件系統(tǒng)，總部在瑞士，并基于瑞士隱私法保護(hù)郵件的隱私，對于安全基本要求很高的用戶來說，非常有用。

安全郵件的問題這幾年被提到的很多，尤其是政府、部隊方面對安全郵件的需求還是很旺盛的。ProtonMail提供端對端的郵件加密方案，并且宣布永久免費。

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.
