TinyWall is a free software to harden and control the advanced firewall built into modern Windows systems. Includes the features that sets it apart from both commercial and freeware firewalls.
TinyWall gives Windows Firewall a sane and secure configuration and presents you with a simple interface where you can easily define what has network access and what not, while preventing other programs from modifing or overwriting your firewall settings.
What this application does:
- Does not annoy you with popups at all, yet it is still extremely easy to add exceptions to your firewall rules.
- Actively blocks hundreds of trojans, viruses and worms.
- Does not require you to know about ports, protocols and application details.
- Prevents malicious programs from modifying the settings of Windows Firewall.
- Does not install drivers or other kernel components, is free and lightweight.
- Multiple and easy ways to whitelist programs
- Automatic learning mode
- Firewall tampering protection
- Password lockdown of settings
- Quick modes, like Normal protection, Allow outgoing, Block all, Allow all and Learning mode
- Support for temporary/ timed firewall rules
- Port and domain blocklists
- Hosts file protection
- Option to always allow communication within LAN
- Option to restrict an application to the LAN
- Recognition of safe software and impostors
- Full IPv6 support
- List established and blocked connections
- View open ports on your machine
- 100% free and clean software. No fees, no ads, no paid upgrades.
The no-popup approach
Most firewalls are based on the same interaction principles. Basically, whenever an application is trying to access the internet, display a popup asking the user what to do. This is not only annoying for the user, but also less than secure. On an average computer, a lot of applications are trying to access the internet. Displaying a popup for each app makes it very probable that unneeded applications will gain access to the network, as it increases the likelyhood of the user granting unnecessary rights to many applications. This phenomenon could be characterized as “security fatigue”, and at its extreme, the user does not verify any more what he gives internet access, but just blindly allows all programs that ask for it.
TinyWall takes a different approach. It does not display popups that “urge users to allow”. In fact, it will not notify you of any blocked action at all. Instead of showing popups, TinyWall makes it easy to whitelist or unblock applications by different means. For example, you can just initiate whitelisting by a hotkey, then click on a window that you want to allow. Or, you can select an application from the list of running processes. Of course, the traditional way of selecting an executable also works. This approach avoids popups, but still keeps the firewall very easy to use. Most importantly, with the no-popup approach, the user will only notice that a program has been denied internet access when he can’t use it any more. Consequently, users will only unblock applications that they actually need and none more, which is optimal from a security standpoint.

What’s New in TinyWall 3.0:
Upgrade note: Your firewall rules will be kept, but GUI settings will be lost after upgrading from an earlier version.
TinyWall 3.0 is a major upgrade that focuses on a complete overhaul of the firewall engine and its capabilities. This allows multiple new features to be added in the current release, resolves previous known issue, and paves the way for future enhacements. The GUI is left mostly intact on the surface, but has also seen multiple fine-tunings and improvements. Some of the major improvements in version 3.0 include:
- Independence from Windows (Defender) Firewall. TinyWall 3.0 is now a standalone firewall that can be run without or side-by-side with Windows’ own built-in firewall.
- Enhanced security through boot-time filtering. Firewall rules are in effect even before TinyWall is loaded on boot, right from the start of the networking stack.
- Support for and automatic handling of UWP applications.
- Added raw- and promiscous-socket filtering, undermining apps that try to monitor or create raw network traffic.
- Full support for Windows File Sharing. The workaround that used to exist for earlier Tinywall versions is no longer necessary.
- Resolved issue where running apps are disconnected when firewall protection feature is triggered.
- Support for automatically allowing child-processes of whitelisted executables. For instance, this simplifies whitelisting most online installers, among many other cases.
- No need for the Connections window to be open anymore to register and list a blocked connection. A blocked connection will be listed even if the window is opened in hindsight.
- Over a dozen user interface improvements, ranging from bugfixes to new hotkeys, better performance, unified batch operations, more useful defaults etc.
- Revised installer with an updated look, option to specify installation path, increased security, and faster installation times.
- … and many more improvements listed in the full changelog.
