Every service listening on your Mac is a door.
Some you opened on purpose, like AirPlay, file sharing for the family, or remote login for a project years ago. Some apps opened for you. On your home network that might be fine. On hotel or coffee-shop Wi-Fi, every stranger in the room can knock.
Mac Shield lists every open door,
from sharing services and remote access to apps and development servers accepting connections. It also covers what starts automatically with your Mac. It separates what other devices can reach from what only your Mac can use, so you can focus on what matters.
Each door comes with the way to close it.
The setting to switch off, or the one-line change to keep a dev server on your Mac only. The live view is free.
Pro Pro keeps 30 days of history on your Mac and shows what changed.
