Security focused FREE VPN service to use the web anonymously, unblock websites & encrypt your connection.
ProtonVPN is a security focused FREE VPN service, developed by CERN and MIT scientists. Use the web anonymously, unblock websites & encrypt your connection. It is designed with security as the main focus, drawing upon the lessons we have learned from working with journalists and activists in the field.
ProtonVPN’s Secure Core architecture gives our secure VPN service the unique ability to defend against network-based attacks. Secure Core protects your connection by routing your traffic through multiple servers before leaving our network. This means an advanced adversary who can monitor the network traffic at the exit server will not be able to discover the true IP address of ProtonVPN users, nor match browsing activity to that IP.
We use only the highest strength encryption to protect your Internet connection. This means all your network traffic is encrypted with AES-256, key exchange is done with 4096-bit RSA, and HMAC with SHA384 is used for message authentication.
Only VPN protocols which are known to be secure – IKEv2/IPSec and OpenVPN. ProtonVPN does not have any servers that support PPTP and L2TP/IPSec, even though they are less costly to operate. By using ProtonVPN, you can be confident that your VPN tunnel is protected by the most reliable protocol.
Our secure VPN sends your internet traffic through an encrypted VPN tunnel, so your passwords and confidential data stay safe, even over public or untrusted Internet connections.
Keep your browsing history private. As a Swiss VPN provider, we do not log user activity or share data with third parties. Our anonymous VPN service enables Internet without surveillance.
We created ProtonVPN to protect the journalists and activists who use ProtonMail. ProtonVPN breaks down the barriers of Internet censorship, allowing you to access any website or content.
