Minimal Firewall 1.8 + Portable

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.
