Fundamentally different

Proton was started in 2014 by scientists who met at CERN and shared a vision of an Internet that puts people first and defends freedom.
Our commitment to transparency, open-source software, and rigorous encryption has seen Proton become recommended by the United Nations and used by millions around the world.

Most tech companies, whether it’s Google or Apple, define privacy as “nobody can exploit your data except for us.” - We disagree. We believe nobody should be able to exploit your data, period.
Our technology and business are based upon this fundamentally stronger definition of privacy, backed also by Swiss privacy laws.

Privacy for a better world

At Proton, we believe that a better world begins with privacy, and our mission is at the heart of everything we do. Privacy isn’t just something we talk about; it’s a deeply held core belief and the reason Proton was created in the first place.

We believe in people before profits, and we use our resources to fight for an open internet that promotes freedom of speech and freedom of information.

The World Wide Web and Proton were born at CERN.

Our story begins at CERN, where the web was born

Proton was founded in 2014 by scientists who met at the European Organization for Nuclear Research (CERN) and shared a vision for a more secure and private Internet. We believe in technical excellence, integrity, and transparency.

Proton is led by scientists, including Sir Tim Berners-Lee, the inventor of the World Wide Web, and we work for the public good.
