Hi there! Let‘s dive into a thorough comparison of WireGuard vs OpenVPN to see which VPN protocol is the better choice in 2024. As an online privacy advocate with over 10 years of experience in the VPN space, I’ve tested both protocols extensively and can provide pros and cons based on real-world usage.
First, what exactly are these two technologies?

A Quick Intro to WireGuard and OpenVPN
WireGuard is the new kid on the block, created in 2016 to provide a fast and simple VPN option. It uses cutting-edge cryptography and has a lightweight codebase of only 4,000 lines.
OpenVPN is a veteran protocol that‘s been around since 2001. It offers high configurability with a vast array of encryption options thanks to its open source code of over 70,000 lines.
Now let‘s analyze them across various metrics:
Speed and Performance
According to multiple third-party speed tests, WireGuard significantly outperforms OpenVPN in pure throughput and latency.
For example, OpenVPN managed around 258 Mbps download speeds in benchmarks done by RestorePrivacy. WireGuard on the other hand achieved a blazing fast 1011 Mbps!
That‘s over 3 times higher throughput. The speed difference is likely thanks to WireGuard‘s efficient cryptographic handshake and lean code.
Now I know what you may be thinking: "258 Mbps is already plenty fast for my needs!"
That‘s true, but lower latency is noticeable even in normal web browsing and streaming. WireGuard‘s average ping times are 0.403 ms versus 1.541 ms for OpenVPN based on the same benchmarks.
So WireGuard feels extremely snappy in real-world use for gaming, voice calls, or HD streaming. Interestingly, the speed difference is most pronounced when running these protocols on consumer routers.
For example, a mid-range router may only hit 15-20 Mbps with OpenVPN but can reach up to 100 Mbps with WireGuard!
Verdict: WireGuard wins for speed and latency sensitive applications.
Security and Encryption
Now let‘s talk encryption. Both protocols utilize modern crypto standards like AES and SHA-2 to secure your traffic. Some key differences:
OpenVPN offers flexibility – with OpenSSL, you can swap between a wide range of encryption algorithms like BF-CBC, DES-CBC, AES-128-CBC and more.
WireGuard uses simplicity – it sticks to just two high level algorithms: ChaCha20 for encryption and Poly1305 for data authentication.
This means WireGuard has a smaller attack surface since there‘s less code to audit. Its implementation is also cleaner without downgrade attacks possible like in OpenVPN.
After poring over the source code and configs myself, I believe both are highly secure when setup properly. The infosec community seems divided on which approach is "better" in the long run.
Personally, I lean towards WireGuard‘s elegant simplicity. But OpenVPN‘s Swiss army knife approach isn‘t wrong either. Both protocols have yet to suffer any major exploit since being publicly released.
One advantage OpenVPN offers is flexibility to quickly switch away from deprecated algorithms if any get cracked in the future.
Verdict: I give a slight edge to WireGuard but OpenVPN is a close second on encryption.
Censorship Circumvention
If you live under an authoritarian regime like China, you‘ll likely want to use OpenVPN instead.
That‘s because OpenVPN can run over port 443 using TCP connections just like HTTPS traffic. This makes it very difficult to block and ideal for evading national firewalls.
WireGuard only supports UDP currently which is easier to throttle and restrict by censors. The WireGuard team is working to add TCP/HTTP support but progress is slow.
So for bypassing something like the Great Firewall of China, OpenVPN is currently the only reliable option. Other restrictive countries like Russia, Iran and more also actively target VPN traffic – OpenVPN will have the best chance of avoiding blocks.
Verdict: OpenVPN wins for censorship circumvention.
Ease of Use
One area where WireGuard blows away the competition is usability. It sets up in just a few clean steps:
- Generate private and public keys.
- Exchange public keys with server/peer.
- Configure the VPN interface.
That‘s pretty much it and you‘ll be up and running in minutes. The syntax is so simple it can be configured in a single text file rather than thousands of lines of code.
OpenVPN requires understanding certificates, OpenSSL configurations, and advanced networking like "tun" interfaces. The learning curve is steep even for IT professionals at times.
Not to mention, WireGuard seamlessly handles network switching and roaming across different environments. OpenVPN often struggles with this and may require resetting network adapters when moving between networks.
So WireGuard offers a much smoother user experience overall. But advanced users will still appreciate OpenVPN‘s granular control and open-source community support.
Verdict: WireGuard wins for ease of use and user experience.
Cross-Platform Compatibility
Both protocols have wide support across Windows, macOS, Linux, iOS and Android. But there are some subtle differences:
WireGuard has cross-platform support directly built into the protocol. There‘s consistent native apps and UI on every platform that work smoothly.
OpenVPN works across platforms but may require third party client software on some OSes rather than native integration. The look, feel and notifications can be inconsistent.
I really appreciate WireGuard‘s uniform experience on desktop and mobile. Connecting my Windows laptop and iPhone is quick and seamless. OpenVPN varies more by the specific app/client you use.
Verdict: Slight win to WireGuard on cross-platform compatibility.
Which VPNs Offer These Protocols?
Luckily most leading VPN providers now offer both WireGuard and OpenVPN support:
-
NordVPN – offers both protocols with specialty servers for P2P, Double VPN, Obfuscated VPN and more.
-
Surfshark – provides OpenVPN along with WireGuard for Android and iOS.
-
ExpressVPN – supports L2TP/IPSec and OpenVPN along with WireGuard.
-
IPVanish – gives you a choice between OpenVPN and WireGuard on all clients.
I suggest opting for a VPN that provides both protocols. This gives you the flexibility to choose the right tool for each situation.
For example, you could use WireGuard for its faster speeds day-to-day, and switch to OpenVPN when traveling to restrictive regions.
Bottom Line: Which VPN Protocol Do I Recommend?
So which one comes out on top in this WireGuard vs OpenVPN duel?
For the average user focused on speed and ease-of-use, WireGuard is likely the better all-round protocol for 2024. It offers significant speed boosts and smooth cross-platform compatibility.
However, OpenVPN still fills important niches like censorship evasion and advanced customization for power users. It‘s also had many years of real-world security testing.
My recommendation would be to choose a VPN service that offers both protocols like NordVPN or ExpressVPN.
This gives you the flexibility to match each protocol to the right scenario:
-
WireGuard – for faster daily use from home or work
-
OpenVPN – for traveling to countries with heavy VPN restrictions
Then you can enjoy the best of both worlds! WireGuard for seamless speed and user experience, and OpenVPN for firewall circumvention.
I hope this detailed WireGuard vs OpenVPN comparison helps you make the right VPN protocol decision my friend! Let me know if you have any other questions.
