Fastest possible VPN connection

Boosting speed everywhere

VPN Accelerator is built into all Proton VPN apps. You'll automatically get the fastest speeds possible wherever you are, no matter what VPN server you connect to. You can expect speeds that are up to 400% faster, especially over less reliable internet connections.

Beating CPU limitations

Proton VPN has re-engineered OpenVPN to properly distribute the CPU load between multiple processes. That greatly reduces the possibility of a single thread becoming overloaded. We apply similar techniques for all VPN protocols that we support.

Reducing latency and network congestion

VPN Accelerator splits the path between the VPN server and the destination into shorter paths. That gives a higher combined performance over the entire path. It also uses an advanced network TCP flow control algorithm called BBR(new window) to reduce latency and bypass congestion on the internet.

Improving packet forwarding

We use several advanced techniques to increase the efficiency of packet delivery on our networks. These include redesigning the VPN protocols to reduce inefficiencies in their code, modifying the Linux stack on our servers to shorten the normal packet-processing path, and using bare-metal servers.

Secure your internet with a trusted VPN

Truly private VPN

Proton VPN is private by default. We don't ask for any personally identifiable information when you sign up. And we have a strict no-logs policy, so we have no data to share with third parties. You choose who you share your data with.

Open-source VPN

All Proton VPN apps are open source and independently audited. That means anyone can check our apps are secure. See what experts say about our apps in the Proton VPN security audit reports.

VPN for freedom worldwide

Proton VPN was created by the team behind Proton Mail, the world’s largest encrypted email service. We exist only to serve our community. That’s why we’ve donated over half a million dollars to causes that advance freedom on the internet.
