Proton Mail
Proton Mail is a secure, end-to-end encrypted email service developed by Proton AG, based in Switzerland. It provides privacy-focused email communication with features like zero-access encryption, where even Proton cannot read user emails, and it operates through a web interface as well as mobile and desktop apps. The service emphasizes user privacy, data protection, and security against surveillance.
Developers should learn about Proton Mail when building applications that require secure communication, handling sensitive user data, or integrating privacy-by-design principles. It is particularly useful for projects involving healthcare, finance, or activism where email encryption and data sovereignty are critical, as it offers APIs for integration and compliance with regulations like GDPR.
