Both protocols are very secure, but less tech-savvy users may prefer to trust the experts at WireGuard, rather than take matters into their own hands. OpenVPN offers greater freedom when it comes to encryption and security, but WireGuard is easier to audit and has a smaller attack surface. ![]() It also makes WireGuard’s possible attack surface much smaller than OpenVPN’s.įurthermore, less code considerably reduces the possibility of bugs occurring in Wireguard. This smaller footprint makes it much easier for security researchers to audit and verify WireGuard’s code than OpenVPN’s. Instead, it forces you to use ChaCha20 for encryption and Poly1305 for authentication.Īs a result, WireGuard requires much less code than OpenVPN: roughly 4,000 lines of code compared to 70,000 (at least). WireGuard, on the other hand, doesn’t offer a choice of encryption. The library supports a wide range of encryption ciphers, including AES, Blowfish, and ChaCha20. OpenVPN uses the OpenSSL library for encryption, which was first released in 1998 and has been thoroughly tested over a long period of time. One of the key differences between OpenVPN and WireGuard is the trade-off between choice and security. There are currently no known security vulnerabilities in both WireGuard and OpenVPN. That’s a pain, but it ensures there are no devices ever using insecure code. Whereas WireGuard would require a software update across all devices. This means that, if a security vulnerability is found in an algorithm, OpenVPN can be quickly configured to use something else. OpenVPN lets you use a wide range of encryption ciphers and authentication algorithms, while WireGuard just has a fixed set for each release. ![]() They conducted 8,200 automated tests daily for a month and concluded NordLynx was up to 2 times faster than OpenVPN.Įncryption Ciphers & Authentication Protocols These results match what NordVPN themselves saw when comparing NordLynx and OpenVPN. On shorter-distance connections, the difference was even more pronounced, with WireGuard running at over double the speed of OpenVPN. Our results found WireGuard was consistently over 75% quicker than OpenVPN, no matter where in the world we were connecting to. Here’s a summary of our OpenVPN versus WireGuard speed findings: Server Location ![]() We connected to NordVPN servers around the world using either the OpenVPN (UDP) protocol or the NordLynx (WireGuard) protocol, and recorded our connection speeds. It’s therefore ideal for running a speed test comparison. NordVPN is an excellent VPN service that was one of the first to support both WireGuard and OpenVPN. WireGuard Is Faster Than OpenVPN in Most VPNs Therefore, we ran the tests ourselves to see which protocol is faster. The WireGuard team admits, however, that these results are “old and crusty and not super well conducted.” WireGuard’s own measures suggest their protocol is at least 3 times faster than OpenVPN – with a throughput of 1011Mbps, compared to OpenVPN’s 258Mbps. The WireGuard protocol is optimized to use multiple processor cores at the same time, and it uses faster encryption methods. As such, WireGuard is considerably faster than OpenVPN. WireGuard was designed with speed in mind. OpenVPN is currently supported by many more VPNs, across many more devices, than WireGuard. VPN services need to include mitigations to ensure user privacy when using WireGuard. OpenVPN adds a data overhead of up to 20%, whereas WireGuard uses just 4% more data (compared with not using a VPN). WireGuard offers a more reliable connection for mobile users than OpenVPN because it handles network changes better. the Great Firewall of China) because it can use TCP port 443. OpenVPN is better at bypassing censors (e.g. Neither protocol has any known security vulnerabilities. WireGuard is twice as fast as OpenVPN, if implemented correctly. Here’s a quick summary of how OpenVPN and WireGuard compare in each key category: Category We’ll also reveal how these protocols came into being, giving you background information on who’s behind them, and explain the differences in how they work. Our extensive lab tests reveal which of the protocols is best in seven key areas, including security, speed, privacy, ease of use, and more. In this in-depth guide we compare OpenVPN and WireGuard to see which VPN protocol you should use. But the new WireGuard VPN protocol has burst onto the scene since its release in 2019, and is now threatening to take that crown away from OpenVPN. OpenVPN was released in 2001 and is traditionally seen as the industry’s gold standard. Two of the best and most commonly-used protocols are OpenVPN and WireGuard. Virtual private networks (VPN) use VPN protocols to create and secure your internet connection. ![]()
