  • WireGuard is a secure, fast, and reliable VPN protocol

    The VPN protocol you use plays a big factor 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 the encrypted VPN tunnel almost immediately, allowing you to connect to the VPN server of your choice almost instantaneously. Once you are connected, WireGuard runs smoother, faster, and more reliably than other VPN protocols. When combined with our unique VPN Accelerator(new window) technology, you can improve speed by over 400%.


    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(new window) and is resistant to brute force and related-key attacks.ProtonVPN’s implementation of WireGuard has also been modified to use a double-NAT system(new window), ensuring that it protects your privacy.

    Stream videos and download files over high-speed connections

    VPN Accelerator

    Our unique VPN Accelerator(new window) 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 ProtonVPN 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. ProtonVPN will also protect your connection while you are connected to BitTorrent and prevent peers from seeing your IP address.

    Frequently Asked Questions

    Which VPN protocol should I use?

    Our Smart Protocol feature, which is enabled by default, automatically picks the best VPN protocol for your needs. If you prefer to manually select the VPN protocol, WireGuard is fast and highly secure. OpenVPN is still considered the benchmark for strong VPN security and can be run in TCP mode for greater resistance to censorship measures. Although not as fast as WireGuard, IKEv2 remains a secure protocol that is supported on a wide range of devices (such as routers).

    Does VPN Accelerator work with WireGuard?

    Yes. VPN Accelerator can improve speed performance by over 400% over long distances or when packet loss is high. When combined with fast and lightweight WireGuard, this can result in very fast speeds under most circumstances.

    Is WireGuard safe?

    WireGuard is an open-source VPN protocol that uses tried and tested cryptographic technologies to secure your connection, including:

    • ChaCha20 for symmetric encryption, authenticated with Poly1305
    • Curve25519 for ECDH
    • BLAKE2s for hashing and keyed hashing
    • SipHash24 for hashtable keys
    • HKDF for key derivation

    WireGuard has undergone various formal verifications and was independently audited before being integrated into the Linux kernel.
