IPsec, WireGuard, OpenVPN.
Why Protocols Matter
A VPN protocol defines how the tunnel is built, secured, and maintained.
Different protocols balance security, speed, and compatibility differently.

IPsec is a long-standing standard that secures traffic at the network layer.
It is widely used for site-to-site VPNs and is supported by most enterprise firewalls and routers.
