VPN Protocols Compared: WireGuard, OpenVPN and IKEv2
A VPN protocol is the set of rules that creates the encrypted tunnel. Choosing the right one can change speed and reliability.
WireGuard
A modern, lightweight protocol with a small codebase that is easier to audit. It is fast and efficient, and it is the default choice for many providers.
OpenVPN
A mature, widely trusted protocol with strong security and flexible configuration. It can be slower and uses more resources, but it works through many restrictive networks.
IKEv2/IPsec
Stable on mobile devices and good at reconnecting when you switch between Wi-Fi and mobile data.
Older protocols to avoid
PPTP and L2TP without IPsec are considered weak and should not be used.
Which to pick
- WireGuard for everyday use.
- OpenVPN when you need to get through firewalls.
- IKEv2 for frequent network switching on phones.
Key takeaway: Use WireGuard unless you have a specific reason to choose something else, and avoid obsolete protocols.
