Murus Menulet runs as an icon in the OS X menu bar, and displays current PF (packet filter) status. PF is the OS X built-in network firewall, and it is disabled by default. Whether you manage PF using the shell terminal or a third party front end (like the free Murus Lite, IceFloor or PFLists apps), you can use Murus Menulet to constantly monitor if PF is enabled or not. Murus Menulet is a free native Swift/Cocoa app.
