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).

WireGuard is a secure, fast, and reliable VPN protocol
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%.
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.
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
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.
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.
Proton VPN is fast, safe, and has easy-to-use features
NetShield increases your browsing speed and keeps your device safe by blocking ads, trackers, and malware.
Our apps feature a kill switch that automatically protects your IP address if the VPN connection is disrupted.
Tor over VPN
You can connect to the Tor anonymity network in a single click and browse your favorite onion sites.
Easy to use
You can instantly connect to the fastest server for your location by simply clicking or tapping our Quick Connect button.
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.
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.
Audited by independent experts
All Proton VPN apps have been fully and independently audited by security professionals. See the results of the security audits for yourself.
Based in Switzerland

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.
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.
