Six popular protocols encrypt the data tunnel in the way you prefer, either when connecting as a client or hosting a VPN server. Built-in WireGuard and OpenVPN VPNs allow you to share your commercial VPN with all connected devices. Out of the security or performance concerns, you can choose specific devices to use the VPN in the device management panel. Hosting a VPN server usually requires a public IP. ZeroTier enables you to host a server even if you do not have a public IP in hotels or cafes.
