SilentWall
Block any application's internet access instantly. Drag. Drop. Done. Take back complete control over what connects on your Windows PC with a single click.
One Action. Total Control.
Other firewall utilities bury you under complex port rules, routing protocols, and endless inbound/outbound prompts. SilentWall has exactly two states: Allowed and Blocked. That's it.
Simply drag any executable (.exe) or desktop shortcut onto the SilentWall interface. The app is instantly cut off from the web. Click it again to restore network access anytime. Perfect for anyone asking: Is this app secretly phoning home right now?
100% Offline Utility
No cloud, no accounts, no tracking.
Zero Driver BSOD Risk
Pure user-mode API security.
Real-Time Alerts, Zero Battery Drain
Unlike traditional monitoring software that constantly polls network interfaces and eats battery, SilentWall hooks directly into standard Windows Filtering Platform (WFP) diagnostic channels:
Event-Driven Alerts (ID 5157)
SilentWall monitors Windows Security Event ID 5157 (WFP Blocked Connection) and issues an instant, silent desktop toast alert the moment a blocked app attempts a connection.
Ultralight Performance Profile
Runs natively compiled (.NET 8 Native AOT), utilizing less than 12MB of RAM (less than a single browser tab) and 0% CPU when idle in the tray.
Atomic Save Configurations
NTFS atomic JSON stream serialization prevents ruleset files from ever corrupting, even during abrupt power loss or sudden PC shutdowns.

Parents & Families
Quickly cut off multiplayer connections for specific games or browsers on a shared family desktop without setting up heavy parental tools.
Developers & Testers
Test application exceptions and offline crash-handling behaviors by denying network access to your compilation builds instantly.
IT Professionals
Rapidly isolate suspicious executable behaviors from the local LAN during forensic auditing—no GPOs or complex VLANs required.
Failsafe Whitelist Protection
A major risk with drag-and-drop firewall utilities is the accidental blocking of critical operating system services, resulting in network lockouts, system crash cascades, or bricked updates.
SilentWall includes permanent whitelists implemented directly into the local firewall service layer. The tool dereferences symlinks and hardlinks using physical handle parameters (`GetFinalPathNameByHandle`), ensuring critical system entities can never be accidentally isolated.
Protected Whitelist Directory & Rules
-
Protected Directories `%SystemRoot%\System32`, `SysWOW64`, and `WinSxS`
-
Protected Core Processes `svchost.exe`, `lsass.exe`, `smss.exe`, `services.exe`, `wininit.exe`
-
Automatic Clean Uninstall Removing the tool immediately flushes all active rules.
