Let's see what Proton VPN is about
Security & encryption
Proton VPN is a Switzerland-based VPN service that keeps no logs of your internet activity which can compromise your privacy. Our apps are all open source and use only the most secure VPN protocols. Below you can learn more about our privacy and security features.
Strong encryption protocols
Our apps use OpenVPN and IKEv2(new window) because they are secure VPN protocols, and we implement them at their strongest encryption settings(new window).
For example, both OpenVPN and IKEv2 use the following security features:
- AES-256 is an NIST-approved cipher that protects your actual data. It is used by the US government to secure top secret information.
- RSA-4096 is a cipher that secures the TLS key exchange used to establish a secure connection between your device and our VPN servers. There are no known methods to defeat RSA when used with a 4096-bit key size.
- Forward secrecy(new window) generates new keys for each VPN session, so even if one session is somehow compromised, no others are. Keys are also rotated regularly within each session
Our apps offer several additional security features to ensure your safety on the internet. DNS leak protection and IPv6 leak protection ensure that your data is always routed through our servers and never to a third party, for example. Meanwhile, our optional kill switch feature stops your internet connection if the VPN ever disconnects, keeping your data protected.
Trust & transparency
Proton was founded by MIT and CERN scientists, and our ethos is grounded in research, peer review, and transparency. To this end, all our apps are 100% open source so that anyone can examine and collaborate with us to improve our code.
GDPR- and HIPAA-compliant.
Proton VPN’s apps for Windows, macOS, iOS, and Android are also audited for vulnerabilities by third-party security firms, the results of which are freely available for anyone to view.
What little data Proton VPN keeps (such as billing information) is protected by Swiss data privacy laws(new window) that are among the strongest in the world. We are fully GDPR- and HIPAA-compliant.
Proton VPN publishes a transparency report(new window) that details any notable legal requests we receive.
Unlike some other VPN services, Proton VPN is completely open about who we are. The physical address of our headquarters and the names of our directors are a matter of public record(new window), and the names and backgrounds of our leadership team are readily available.
