Map the trust boundary

A managed VPN depends on the provider's gateway and policies. A self-hosted exit depends on your configuration plus the host, upstream network, DNS, patching, and incident response.

The tunnel protects client-to-gateway traffic. It does not protect the path beyond the gateway or turn either model into an anonymity system.

Build and verify

  • Use the OpenFactory prompt as a reviewable WireGuard build-plan starting point, not a finished deployment.
  • Provision private keys at runtime and configure the real endpoint, forwarding, firewall, and DNS policy outside the recipe.
  • Test routing, DNS, fail-closed behavior, revocation, reboot, updates, and recovery in the target environment.
