Is Proton VPN trustworthy?

Proton VPN is built by the same team behind Proton Mail, the world’s most popular encrypted email provider. We started a safe and secure VPN because we wanted to protect the journalists and activists that use Proton Mail and help them bypass government censorship. Proton VPN is based in Switzerland, so you can benefit from strong privacy laws. We do not track, store, or collect any of your browsing information and rely on powerful encryption technologies to protect your data.

What encryption protocols does Proton VPN use?

Proton VPN only employs well-known and vetted encryption standards, such as AES-256. Similarly, we only use VPN protocols that are known to be secure, like OpenVPN, IKEv2, and WireGuard, to safeguard your data. We do not offer connections that use the L2TP and PPTP VPN protocols as they do not meet our security requirements.

Does Proton VPN have a kill switch?

Yes, Proton VPN offers a kill switch feature that automatically disconnects your device from the internet if your VPN connection is interrupted.

A reliable VPN with strong encryption

Proton VPN is built by the same team that created Proton Mail, the world’s largest encrypted email service. We have a long track record of implementing cybersecurity solutions, and we are committed to safeguarding your privacy with advanced encryption technologies.

Encrypted network traffic

Proton VPN encrypts all network traffic using either AES-256 or ChaCha20, both of which are extremely secure.

VPN connections that use the OpenVPN or IKEv2 VPN protocol are secured with AES-256. While no encryption cipher is unbreakable, it would take even the most advanced computer billions of years to break AES-256 with a brute-force attack.

If you use the WireGuard VPN protocol, your connection will be encrypted with ChaCha20, which is an advanced encryption cipher that is just as secure as AES-256 and slightly faster.

Perfect forward secrecy

Proton VPN only uses encryption ciphers and VPN protocols that support perfect forward secrecy. This means that each time you connect to our VPN, you generate a unique set of encryption keys. This way, even if a future VPN session is compromised, your past sessions will remain secure.

Secure key exchange

Proton VPN uses the Diffie-Hellman key exchange to securely generate session keys. The Diffie-Hellman is a secure approach that allows the server and the client to agree on a key, without ever communicating it.

Proton VPN is trusted, safe, and secure

Open source

Proton VPN apps are open source and available for inspection by the public. This enables us to take advantage of the entire cybersecurity community when it comes to finding and fixing any potential vulnerabilities and means anyone can ensure that our apps perform as advertised.

Independently audited

All Proton VPN apps have undergone a thorough, independent audit by leading cybersecurity firms. These audits are necessary so that people can see what an expert thinks of our apps’ security. You can find the results of all these audits on our website.

Based in Switzerland

Proton VPN is based in Switzerland, meaning your data is protected by some of the strongest privacy laws in the world. Switzerland is also not a part of any 5 Eyes, 9 Eyes, or 14 Eyes intelligence-sharing agreements, and any data requests from foreign governments must first be approved by the appropriate Swiss authority.

Access blocked content with a secure VPN

Secure Core VPN

Our hardened Secure Core servers are located in countries with strong privacy laws. Your online traffic is routed through one of these servers for added security.

NetShield Ad-blocker

Proton VPN’s NetShield Ad-blocker prevents online trackers and other malware from infecting your device.

DNS leak protection

Instead of relying on third-party DNS servers, Proton VPN runs our own DNS servers. Our apps also encrypt your DNS queries and include them in the VPN tunnel.
