Justice Wall
Somebody knocked. You decide whether to answer.
Justice Wall was built for people who are not technical. It works alongside Windows Defender Firewall rather than replacing it, and its whole interaction is one plain-language question: something tried to reach your computer on a port that is not normal — do we let it through?
The simplicity is deliberate. Underneath, it registers its own sublayer on the Windows Filtering Platform, which makes it a peer of the built-in firewall in the same engine rather than a program shelling out to command-line tools. It needs no kernel driver and no signed certificate, and if the service is stopped the filters stay in place, so a crash leaves the machine protected rather than silently open.
Ports are shown as tiles that fill and flow with real traffic, so activity reads at a glance without a number to interpret. Outbound traffic is left open but visible, each connection carrying a single button that stops it. Closing outbound on a home machine produces dozens of prompts on the first day and teaches the user to click yes, which is the exact reflex an attacker needs.
