Download TinyWall for Windows PC v3.6.1 for Windows PC

A tiny, free front-end that makes the built-in Windows Firewall easy to control — whitelist apps in two clicks, watch live connections and block everything...

Features

• It makes Windows Firewall rules understandable, letting you whitelist an application in two clicks straight from the system tray.
• It adds virtually no overhead, because it installs no drivers and runs no scanning engine of its own.
• The connections window shows live blocked and allowed attempts, so noisy or suspicious programs are easy to spot.
• It protects the firewall configuration itself with an optional password and tamper protection that the stock interface lacks.
• The installer is only about 2 MB, the program is free and open source, and there are no advertisements or bundled extras.

Considerations

• TinyWall is a controller for Windows Firewall rather than an independent firewall engine, so it depends on that service staying enabled.
• The interface is purely functional, and its modes and exception types take a little learning before they feel natural.
• It offers no antivirus, web filtering or other suite features, because controlling network access is all it sets out to do.

Double-click TinyWall_x86.msi (the same package serves both 32-bit and 64-bit Windows) and approve the administrator prompt so it can register its service with Windows Firewall.

Complete the short wizard. TinyWall starts automatically and places its icon in the system tray, from where all modes, whitelisting and settings are controlled.

Right-click the tray icon and use the application exceptions menu to allow your browser and other trusted programs, or let the learning mode observe connections before you lock the rules down.

Is a TinyWall firewall good?

TinyWall is good at a specific job: it is a lightweight front-end for the built-in Windows Firewall that fixes its biggest weakness — usability. You whitelist programs in two clicks, see which applications are trying to connect, and switch between modes such as normal protection, block all, or allow outgoing only. It adds no packet-filtering driver and no background scanning engine, so overhead is almost zero.

What are the key differences between TinyWall and SimpleWall?

Both are lightweight front-ends rather than full security suites. TinyWall's approach is to manage the built-in Windows Firewall itself: your rules live in Windows Firewall, TinyWall hardens them against tampering and blocks known malicious traffic patterns, and all control happens from a small tray app with whitelist modes. SimpleWall is a separate front-end built directly on the Windows Filtering Platform with its own rule management. The practical difference is where your rules live and how you edit them day to day.

Is there a free firewall app for Windows?

Yes — TinyWall is free, with donations welcomed by its developer, Karoly Pados. Rather than replacing Windows Firewall it makes it usable, adding simple program whitelisting and protection modes to the firewall already built into Windows 7 SP1 and later.

Does Windows have a built-in firewall?

Yes, Windows Firewall is built into Windows — what it lacks is a friendly interface. TinyWall is a front-end for that built-in firewall: instead of cryptic rule dialogs you get a tray application for whitelisting programs and switching protection modes, with no extra filtering driver installed.

What is the best free firewall for Windows 11?

If you want free and light, TinyWall on top of the built-in Windows Firewall is a sensible combination: the filtering is done by Windows' own firewall, while TinyWall adds two-click whitelisting, connection visibility and tamper protection for the rules — without the weight of a full security suite. The current version listed here is 3.6.1.
