Firewall App Blocker

Firewall App Blocker is an essential security software for users who want to simplify the procedure of blacklisting and whitelisting applications that want to communicate with outside internet networks past your built-in Windows Firewall service.



This app does not add any new security features, but instead is focused entirely on providing a new user interface and a simplified set of controls to users who do not want to fire up their Control Panel, access the Windows Firewall configuration page, and do the entire procedure for blocking a particular app. Instead, users of Firewall Blocker App can simply access a streamlined interface that promotes incredibly easy and fast handling of app Firewall permissions.

What’s New

• UI Fix: Resolved the issue where the Enable WhiteList option disappeared after changing the interface language
• Command Prompt Fix: Addressed a minor bug affecting command prompt functionality
• Sorting Improvement: Fixed entry sorting so newly added items can appear at the top
• New Language Support: Added partial localization for “File → Netsh Commands” section

The utility consists of a single screen with a set of brightly colored main tools (Apply, Add, Delete, Refresh, Export, Import, and Home) and a listing of currently managed apps. Users can very easily add or remove new apps and manage their firewall permissions by right-clicking on them and choosing from the main configuration options (Block, Unblock, Block All, Unblock All) or several secondary tools for easier management of apps (Delete, Rename, Delete All, Run the File, Open Location, File Properties, and Refresh).



Because of its simple toolset that provides fast access to default Windows Firewall app management settings, this app does not feature in-depth preferences or any way to customize its workflow or UI style. It, however, does offer quick access to view or reset your Windows Firewall settings to their default state. The app runs fast even on modest or old PC configurations and can enable users to perform complicated Firewall configurations in just a few mouse clicks.

Firewall App Blocker weighs just over a single megabyte and can run on any modern version of Windows OS (XP, 7, Vista, 8, and 10) as a portable application, straight off the USB stick or any location on your local storage.



FAQs

What does Firewall App Blocker actually do differently from Windows Firewall?
Firewall App Blocker (FAB) is a lightweight front-end for Windows Firewall that simplifies blocking apps from accessing the internet. Instead of navigating complex firewall rules, you can block or allow programs with a simple drag-and-drop interface.

Is Firewall App Blocker portable and safe to use?
Yes. According to its official page, it’s a portable tool that doesn’t require installation. It works by modifying Windows Firewall rules, so it doesn’t introduce its own firewall engine, which makes it relatively safe when downloaded from the official site.

When is Firewall App Blocker actually useful?
It’s especially useful when you want to quickly block specific apps (e.g., games, updates, or telemetry) from going online without dealing with advanced firewall settings, making it practical for everyday control over network access.
