VPN Protocols Explained: WireGuard vs OpenVPN vs IKEv2

What Is a VPN Protocol?

A VPN protocol is the set of rules that determines how your data travels between your device and the VPN server. Think of it as the language your VPN speaks.

The Major VPN Protocols

  • Only 4,000 lines of code (easier to audit for security)
  • Lower battery consumption on mobile devices
  • Quick connection times

Cons:

  • Newer, so less battle-tested
  • Default configuration stores IP addresses

Best for: Speed-focused users, mobile devices, streaming

OpenVPN - The Trusted Veteran

OpenVPN has been the industry standard for over 15 years.

IKEv2/IPsec - The Mobile Champion

  • Fast connection establishment
  • Good security
