Meet HearthGate: the Mac-side server layer for secure VNC over SSH. It can use OpenSSH's hybrid ML-KEM key exchange when supported, enforce VNC lockdown through the firewall, and keep familiar RFB/VNC viewers, including full legacy client support, in your workflow.
Post-quantum-ready SSHOpenSSH's hybrid ML-KEM key exchange is used automatically when the installed SSH stack supports it.
Firewall VNC lockdownThe screen port can stay reachable only through the SSH-gated localhost path.
RFB/VNC viewer compatibilityKeep using common third-party viewers such as RealVNC, Remmina, TigerVNC, TightVNC, MobaXterm, AVNC, and Screens.
Keys scoped to where they belongCreate keys for LAN-only access, internet-only access, or both, with generated authorized_keys constraints enforcing the boundary.
Scripts on connect and disconnectTrigger your own automation when a tunnel opens or closes, with delayed execution, timeouts, and loop protection built in.
SSH hardening from the UIMove the SSH port, bind IPv4/IPv6, set idle timeouts, disable password/root login, and let heartbeat cleanup handle wake events.
