Proton was founded by scientists, and we believe in research, peer review, and transparency. All our apps are open source and independently audited so that anyone can use, inspect, and trust them.

Your data, your rules

As an organization defending press freedom and access to information, privacy is both an ideal and a requirement. When we revamped our email communication architecture, Proton Mail provided adequate cornerstones: internal E2EE, audited open source and a growing secure ecosystem, thus allowing us to fulfill the latter and to approach the former.

We use Proton Mail for our medical imaging practice. Migration from our self-hosted servers was seamless, and our team loves the simplicity of sending patient reports to and from our partners.

Previously, we had a Google account, which was then transferred through Outlook. It was constantly having issues and we wanted more security for our attorney and client data and communications. Proton Mail makes it easy. It just works.

Being a startup, I am somewhat sensitive to price but I don't expect email to be a major expense. I simply need it to work. My plans and contracts get delivered to my clients. I also need access on both my computer and phone. With Proton Mail, I get all of that and the security is a bonus.

[Proton Mail’s] encryption means I don't have to worry about my mail being read before it reaches the recipient. Other companies fail to respect my privacy.
