WireGuard is a secure, fast, and reliable VPN protocol

The VPN protocol you use plays a big part in determining the speed, security, and reliability of your connection. WireGuard is a modern VPN protocol that has revolutionized the VPN space with its extremely lightweight and open-source code. Because WireGuard is so lightweight, it offers improved performance over other VPN protocols.

High-speed VPN

WireGuard establishes an encrypted VPN tunnel almost immediately, allowing you to connect to the VPN server of your choice almost instantaneously. Once you're connected, WireGuard runs smoother, faster, and more reliably than other VPN protocols. When combined with our unique VPN Accelerator technology, you can improve speed by over 400%.

Lightweight

VPN protocols can be quite complicated and require many lines of code, but not WireGuard. In place of OpenVPN, which uses over 400,000 lines of code, WireGuard uses less than 5,000 lines of code. This means a VPN connection that uses WireGuard is faster, uses less battery, and takes less computing power. It also means that WireGuard code is easy to maintain and audit, improving its security.

Advanced encryption

WireGuard uses the state-of-the-art ChaCha20 encryption cipher to encrypt the VPN tunnel and protect your data. It enables perfect forward secrecy and is resistant to brute force and related-key attacks.
Proton VPN’s implementation of WireGuard has also been modified to use a double-NAT system, ensuring that it protects your privacy.

Stream videos and download files over high-speed connections

VPN Accelerator

Our unique VPN Accelerator technology reduces network latency and overcomes CPUs’ limitations in processing VPN protocols to increase connection speeds by over 400%. VPN Accelerator is on by default on all Proton VPN apps and helps improve the speed and stability of your VPN connection no matter what VPN protocol you use.

High-speed streaming

By connecting to our exclusive Plus servers, you can watch your favorite movies and TV shows on popular streaming services, including Netflix, Disney+, and HBO Max. These servers support 10 Gbps connections, meaning you can watch your shows in HD without any buffering or interruptions.

Fast BitTorrent downloads

You can quickly share and download files by connecting to our servers that are located in countries that allow P2P file sharing and have been optimized to handle P2P traffic. Proton VPN will also protect your connection while you are connected to BitTorrent and prevent peers from seeing your IP address.

No-log VPN

We do not keep any logs of your online activity or metadata, meaning we have no data to share with anyone. We implemented a modified version of WireGuard to ensure it follows this policy.

Open source

Our apps are completely open source, so anyone can verify their code. The WireGuard VPN protocol is also open source, which means potential vulnerabilities are easier to find and fix.
