Minimal Firewall is a lightweight Windows application designed to work alongside Windows Firewall, giving users greater control over outbound network connections. I found that its primary focus is simplicity and privacy rather than replacing the built-in firewall. With Lockdown Mode enabled, all applications without existing Windows Firewall rules are blocked by default, allowing only trusted software to access the internet. The software also provides real-time connection alerts, quick rule creation, wildcard support for frequently updated applications, and management of UWP apps and Windows services. Since all rules and logs remain stored locally and the application contains no telemetry, it offers an appealing solution for privacy-conscious Windows users.

Interface and Usability
Minimal Firewall focuses on providing a straightforward interface that makes managing firewall rules more approachable than using Windows Firewall alone. While using the software, creating allow or block rules felt quick, especially when responding to real-time connection alerts. The notification options let users choose between popup alerts and quieter in-app notifications depending on their preferences. The inclusion of light and dark themes also makes the interface comfortable for extended use. Although Lockdown Mode may require creating rules for newly installed applications, the overall workflow remains easy to understand once the initial configuration is complete.
