We’re building an internet that protects privacy, starting with email. We are scientists, engineers, and developers drawn together by a shared vision of protecting civil liberties online. This is why we created ProtonMail, an easy to use secure email service with built-in end-to-end encryption and state-of-the-art security features. Our goal is to build an internet that respects privacy and is secure against cyberattacks.

We are committed to developing and widely distributing the tools necessary to protect your data online. Our team combines deep mathematical and technical knowledge from the world’s top research institutions with expertise in building easy to use user interfaces. Together, we are building the encrypted communication technologies of the future. ProtonMail is a Swiss-based secure email service, brought to you by CERN and MIT scientists. We provide free and easy-to-use encrypted email.

Millions of people in 150 countries use ProtonMail to securely email friends, family, and colleagues. We protect your privacy and ensure that nobody, not even us, can read your communications. Our end-to-end encryption is completely seamless, so there is nothing to install and no extra steps before you can start emailing securely.
