A macOS menu bar utility that maps every port, device, and power draw on your Mac. Live topology, hub and daisy-chain support, and link speeds — all local, no telemetry.
Do you need to map a specific TCP or UDP port on your machine to another port on another machine? Do you want to limit access to a server on your machine based on the IP address of an incoming connection request?
CloseTheDoor indentifies all the listening ports TCP/UDP over IPv4/v6 and the associated program files. This will help you to detect security holes and close backdoors when you want to prevent remote attacks.
