Proton Mail
End-to-end encrypted email service
Summary
Proton Mail is the largest end-to-end encrypted email hosting service. It was launched in 2014 by Andy Yen, Jason Stockman and Wei Sun. Proton Mail is headquartered in Geneva, Switzerland. It is owned by the non-profit Proton Foundation through its subsidiary Proton AG, which also operates Proton VPN, Proton Drive, Proton Calendar, Proton Pass, Proton Wallet, Proton Meet, and Lumo AI. Proton Mail uses client-side encryption to protect email content and user data before they are sent to Proton Mail servers, unlike other common email providers such as Gmail and Outlook.com.
