Proton is privacy for everyone
Welcome to a better internet where privacy and freedom come first
Proton is privacy you can trust
Your privacy is ensured by strong encryption, open-source code, and Swiss privacy laws.

Fundamentally different
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.
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.
Over 100 million people and businesses have signed up for Proton
End-to-end encryption
Our end-to-end encryption and zero-access encryption means 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.
Swiss privacy
Proton is based in Switzerland. This means all user data is protected by strict Swiss privacy laws.
We are a neutral and safe haven for your personal data, committed to defending your freedom.
Security made easy
Proton’s encrypted services are so simple and intuitive that anyone can use them.
Easy Switch lets you instantly import and encrypt your data from Google, Outlook, or other services in just a couple of clicks.
Open source & audited
As a company created by former scientists, we believe strongly that trust is earned through transparency and peer review.
All our apps are open source and independently audited by security experts so that anyone can use them, inspect them, and trust them.
One account, any device
Proton apps are available on all devices (Android, iPhone and iPad, Windows, Mac, Linux, and more), and with one Proton account, you can use all of our privacy-by-default services.
Proton apps have advanced anti-censorship technologies built-in, so you can access your email, files, calendar, passwords and VPN even from countries with limited online freedom.
Free forever
We believe that privacy is a human right, and that's why Proton services are always available for free and our encryption technology is free software.
Proton has no ads and does not sell your data. You can support the service by upgrading to a paid account with more features.

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.

Built by the community, for the community
Proton is a community-first organization, created through a public crowdfunding campaign, and built with community input. To this day, Proton's only source of revenue is subscriptions from users.
We exist only to serve you, not advertisers or other third parties. By choosing Proton, you join a movement of millions of volunteers, contributors, and users creating an Internet that puts people first.
