VPN Protocols Explained
Written by DexterVPN Editorial Team
VPN protocols are the rule sets and cryptography used to build your encrypted tunnel. WireGuard prioritizes simplicity and speed, OpenVPN offers mature UDP/TCP flexibility, and IKEv2/IPsec excels at mobile reconnects. Your app should let you switch when one protocol is blocked or slow.
Quick comparison
| Protocol | Best for | Watch out for |
|---|---|---|
| WireGuard | Everyday speed on open networks | UDP blocking on strict Wi-Fi |
| OpenVPN | Fallback with TCP on filtered networks | Higher overhead on some devices |
| IKEv2/IPsec | Phones switching Wi-Fi ↔ cellular | Corporate firewalls may block it |
