We are headquartered in Switzerland, which has some of the world's strongest privacy laws. Switzerland is also outside of EU and US jurisdiction and is not a member of the 14 eyes surveillance network.
When you connect to Proton VPN, you enjoy the same legal protections that ensure the privacy of all Swiss citizens. Proton VPN is built by the same group of scientists who met at CERN and founded Proton Mail, the largest encrypted email provider. We are based in Switzerland, allowing us to pass the benefits of Swiss data protection on to you.
Under Swiss data protection regulations, we are not required to comply with requests that are not supported by a Swiss court order.
