ShizuWall is an Android firewall application that restricts network access for individual apps without creating a VPN connection. It uses Android's connectivity controls to block networking at the package level rather than intercepting traffic. Users can restrict selected applications, including copies installed in work profiles or cloned environments. The application supports Shizuku, root access, and a local ADB backend configured through wireless debugging. Saved profiles allow different firewall configurations to be activated for specific situations. Quick Settings controls, widgets, and a floating button provide convenient access. Tasker, MacroDroid, and ADB broadcasts enable automated network restrictions. ShizuWall operates locally without analytics or telemetry and supports Android 11 and newer. Android resets its firewall rules after reboot.
