TinyWall is a free, open-source firewall for Windows, intended for private users, family PCs, and small-office or home-office computers.
What TinyWall is
TinyWall is a free, open-source firewall for Windows, intended for private users, family PCs, and small-office or home-office computers. It avoids real-time popups for blocked actions and provides several ways to whitelist applications. Controls include whitelist learning, timed rules, quick modes, IPv6 support, and integrated port and domain blocklists. Users can view established and blocked connections as well as open ports. TinyWall also protects Windows Firewall settings from modification and includes hosts-file protection and boot-time filtering. Its maker says it installs no drivers or kernel components. After installation, it blocks most network communication until needed programs are whitelisted, and the maker advises against installing it over a remote connection. The latest version supports desktop Windows 11 and Windows 10 version 21H2 (build 19044) or newer; version 3.2.5 also supports Windows 8.1, 8, 7, and Windows Server 2019, 2016, and 2012 R2. TinyWall does not include HIPS, anti-malware, or antivirus modules.
Good
- No real-time popups for blocked actions.
- Includes whitelist learning, timed rules, and quick modes.
- Lists established and blocked connections and open ports.
- Protects Windows Firewall settings from modification.
Watch out
- Installation blocks most network communication until programs are whitelisted.
- No command-line interface, remote management, or domain-controller integration.
- Firewall only; no HIPS, anti-malware, or antivirus modules.
- Not well suited to servers or larger networks.
Who it suits
TinyWall suits private users, family PCs, and small-office or home-office computers running supported Windows versions. The maker says it is not well suited to headless machines, servers, or networks with more than five computers.
Verdict
TinyWall offers Windows firewall controls without real-time blocking popups, along with visibility into connections and ports. Its management limits and firewall-only scope make it a poor fit for some server and larger network setups.
