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.
