Our verdict: TinyWall is a light, quiet firewall controller for people who prefer to whitelist apps rather than answer pop-ups. It blocks most traffic right after installation, so you need a few minutes to allow your apps. It has no connection prompts, which some users will miss.
About TinyWall
TinyWall is a free firewall by Károly Pados that builds on the filtering platform built into Windows. It installs no drivers or kernel components, uses few resources and shows no pop-ups. Instead, you allow programs from the tray menu: by clicking a window, picking a process or choosing a file.
After installation TinyWall blocks most communication until you whitelist programs. It adds tamper protection for its settings, blocklists for known malicious hosts, temporary rules, UWP app support and boot-time filtering. Version 3.5 added ARM support and a dark mode. The code is on GitHub under the GPL v3, and the author states that it collects no data and has no telemetry.
What it does well
- Whitelist by window, process or file. Allow a program from the tray menu without writing rules.
- No pop-ups. Blocks silently instead of asking about every connection.
- Temporary rules. Allow an app for a limited time or until restart.
- Blocklists. Optional lists that block known malicious hosts and ports.
- Tamper protection. Password-protects settings and guards rules against other programs.
Who it is for
Good fit
Users who want outbound control in Windows Firewall without constant prompts.
Look elsewhere
Beginners who expect a firewall to work without setup, or anyone installing over a remote desktop connection.

- Light on resources
- Temporary rules and blocklists
Cons
- Blocks most traffic right after installation until you whitelist apps

How to install TinyWall
Do not install TinyWall over a remote connection, or you may lock yourself out. After installation most network traffic is blocked: open the tray menu and use Whitelist by window, process or executable for your browser and other apps. The x86/x64 MSI covers both 32-bit and 64-bit PCs; ARM PCs need the separate arm64 download.
