Improve VPN speeds by up to 400% with VPN Accelerator

VPN Accelerator is a set of technologies unique to Proton VPN that delivers the best possible VPN speeds.

  • Browse the internet up to 400% faster
  • Enjoy a more stable, reliable VPN connection
  • Benefit from VPN Accelerator automatically on all devices
  • Fastest possible VPN connection

    VPN Accelerator is built into all Proton VPN apps and ensures no matter which VPN server you connect to or where you are, you will automatically get the fastest speeds possible. You can expect to see speeds that are up to 400% faster, particularly over less reliable internet connections.

    Overcoming CPU limitations

    Proton VPN has re-engineered OpenVPN to properly distribute the CPU load between multiple processes, greatly reducing 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, resulting in 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. Find out more about how VPN Accelerator works.

    Improving packet forwarding

    We use several advanced techniques to increase the efficiency of packet delivery on our networks. These include redesigning the VPN protocols themselves 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

    Keep your Data private with Proton VPN

    Proton VPN is private by default. We do not require any personally identifiable information at sign up and we implement a strict no-logs policy, meaning we have no data to share. You are able to choose who you share your data with and who you keep it private from.

    Open source and audited

    All Proton VPN apps are completely open source. This means anyone can examine our apps’ code to ensure they are secure and can be trusted with your privacy. We also submit all our apps to audits by independent security experts and publish the final reports online.

    Proton VPN supports freedom around the world

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

    Frequently Asked Questions

    Does VPN Accelerator really improve VPN speeds by up to 400%?

    Yes, especially when connecting to VPN servers over large distances or when using a VPN on networks that have packet loss.

    Can I disable VPN Accelerator?

    VPN Accelerator is enabled by default because it can dramatically improve speed performance under certain conditions, with no real downsides. However, the feature can be disabled and enabled in your app’s Settings. See How to use VPN Accelerator for more details.

    Does VPN Accelerator work for all VPN protocols?

    Yes. Our unique technology can greatly improve VPN speeds, whether you use OpenVPN TCP, OpenVPN UDP, WireGuard, or IKEv2.

    Should I connect to a VPN server further away from me to benefit from VPN Accelerator?

    No, you will still achieve the best VPN speeds if you connect to a VPN server that is located as close to you as possible. However, if you do connect to a more distant VPN server, or if you are accessing content (i.e., a website) hosted on a server geographically distant from you, VPN Accelerator will dramatically improve your internet speeds.
