LANGhost hardens exactly the window between “network interface comes up” and “WireGuard tunnel is established.” Without it, your real MAC, hostname, and DHCP identifiers are visible to the public network operator during that bootstrap phase, before any application traffic is protected by the tunnel. I recommend not adding unnecessary complexity by chaining Tailscale and another VPN. A second VPN would only add value if you specifically need to hide your home IP from destination servers.

The perfect use case is untrusted public networks where you want to avoid tracking. It’s just another layer of defense and i highly recommend using a VPN alongside this.
