Grundlæggende anderledes
Proton was started in 2014 by scientists who met at CERN and shared a vision of an internet that defends freedom and puts people first.
Our transparency, open-source software, and rigorous encryption have earned Proton millions of users around the world — and the recommendation of the United Nations.
Tech companies like Google or Apple define privacy as “nobody can exploit your data, except for us.” We believe nobody should exploit your data, period.
Vores teknologi og forretning er baseret på denne grundlæggende stærkere definition af privatliv, som også bakkes op af den schweiziske lovgivning om privatliv.
Privatliv for en bedre verden
At Proton, we believe that a better world begins with privacy, and this is at the heart of everything we do. Privacy isn’t just something we talk about; it’s a core belief and the reason Proton was created in the first place.
We also believe in people before profits, and our primary shareholder is the nonprofit Proton Foundation, whose mission is to fight for an open internet that promotes freedom of speech and freedom of information.

End-to-end kryptering
Our end-to-end encryption and zero-access encryption mean that no one (not even Proton) has the technical means to access your data without your permission.
We don’t sell ads and can’t share your data. At Proton, privacy isn’t a promise, it’s mathematically ensured.
Schweizisk privatliv
Proton is based in Switzerland, and your data does not go to the cloud. Instead, it stays under the protection of some of the world’s strongest privacy laws.
We are a neutral and safe haven for your personal data, committed to defending your freedom.

Vores historie begynder på CERN, hvor internettet blev født
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.
