Minimal Firewall

Minimal Firewall works in conjunction with Windows Firewall to block all unknown connections by default, prompting you to create application-based rules to mitigate malware, telemetry, and data leaks. Completely eliminate applications that call home without your knowledge. Minimal Firewall provides a more secure and integrated approach by interacting directly with the native Windows Firewall, eliminating the need for risky system modifications.

Core Features
Lockdown Mode: The core of Minimal Firewall. Enable this mode to block any network connections that are not in Windows Firewall rules by default. No program will connect without your explicit command.
Real-time connection alerts: Get instant notification when a blocked program tries to connect, allowing you to make decisions on the spot. You can choose to enable annoying pop-ups or silent in-app notifications.
Simple rule creation: Allow or block any app permanently with a single click, or allow or block it temporarily.
Wildcard rules: Easily manage frequently updated programs (like web browsers) by creating rules that apply to any version in a specific folder.
Services and UWP support: Manage rules for modern Windows Store apps and background system services, not just traditional desktop programs.
Light and dark themes: Clean, easy-to-look-at user interface, day or night.
100% local and private: Minimal Firewall stores no telemetry, doesn’t connect to the internet itself, and all your rules and logs are stored locally on your machine.
Mobile: Minimal Firewall can be replicated into a mobile app and you can even delete all the rules created by this app within the app.
