WireGuard and OpenVPN are two of the most popular VPN protocols, each with strengths for different needs. This no-nonsense comparison cuts through the tech jargon to help you choose the right one for speed, security, or specific devices.
Quick Verdict
Choose WireGuard if you need:
- Blazing-fast speeds (especially on mobile)
- Modern encryption with smaller codebase
- Seamless switching between networks
Pick OpenVPN for:
- Maximum compatibility (works on ancient routers)
- Battle-tested security audits
- TCP mode for restrictive networks
Most premium VPNs like NordVPN and ExpressVPN now support both.
Technical Face-Off
| Feature | WireGuard | OpenVPN |
|---|---|---|
| Release Year | 2015 | 2001 |
| Code Size | ~4,000 lines | ~600,000 lines |
| Encryption | ChaCha20 (modern) | AES-256 (proven) |
| Handshake | 1-RTT (faster) | 4-RTT (slower) |
| Best For | Mobile devices, gaming | Firewall evasion, legacy systems |
| Try With | Get NordVPN | Get ExpressVPN |
Who Should Use Which?
WireGuard Wins When:
- You're gaming or video calling (lower latency)
- Switching between WiFi and mobile data often
- Using a Raspberry Pi or resource-limited device
OpenVPN Shines For:
- Bypassing strict firewalls (like in schools)
- Older devices that don't support new kernels
- When TCP port 443 is your only option
Pro tip: Surfshark offers both protocols plus a WireGuard-based “WireGuard” option.
Frequently Asked Questions
Is WireGuard more secure than OpenVPN?
Both are secure when configured properly. WireGuard's smaller codebase means fewer potential vulnerabilities, while OpenVPN has undergone more real-world testing. Most security experts consider them equivalent for typical users.
Can I use both protocols simultaneously?
Yes! Many VPN providers let you switch between them in their apps. ExpressVPN even auto-selects the best protocol for your network.
Why do some VPNs modify WireGuard?
Standard WireGuard doesn't assign dynamic IPs well. Services like NordVPN's “NordLynx” add privacy protections while keeping the speed benefits.
Does OpenVPN work in China?
Sometimes. Its TCP mode on port 443 can mimic HTTPS traffic, but China's Great Firewall often blocks it. WireGuard's UDP packets are usually detected faster.
Need Help Choosing?
For most users in 2024, we recommend a VPN with both protocols like NordVPN (NordLynx for speed + OpenVPN for reliability). Their 30-day money-back guarantee lets you test both risk-free.
