Wireguard is a protocol and program for making point-to-point VPN connections. It's notable because it's simple (compared to alternatives like OpenVPN), so simple it became a kernel module which made it very fast. These guys implemented it in an FPGA because they could.
i think of wg more as point-to-point, encrypted network interfaces cards than a vpn.
That's what a vpn is - a virtual private network.
You can make a private network by adding more network interface cards and wiring. If you do it with software instead, it's virtual.
