Choose what connects

Control each connection

Keep apps offline until you choose to give them access. SecureWall lets you manage application allow and block rules on Windows 10 21H2+ and Windows 11, with prompts for eligible unknown outbound connections.

Built from TinyWall and open source under GPLv3. Review the code, bring your existing settings, and manage connections from the Windows tray.

Choose when an app gets access

When a connection prompt appears, choose Allow outgoing to save an outbound TCP/UDP rule. Choose Ignore or dismiss it to keep your current rules.

See what is connecting

Open Network Activity from the tray to see observed allowed and blocked connections, TCP states, and local listening ports. The view refreshes every second.

Features

Keep rules per app

Allow the apps you need online and block the ones you want to keep offline. Existing explicit blocks stay in place when you approve a connection prompt.

Troubleshoot a blocked app

Enable diagnostic logging in Settings to help investigate connection problems. Logging is off by default, and collected reports stay local until you choose to share them.

Bring your TinyWall settings

Import a TinyWall .tws export to bring over your whole saved configuration, including rules and other settings. Review the imported settings before making changes.

Before you install

v0.4.1 is unsigned alpha software and is not end-to-end verified. Read the setup guide before a trial. Verify the MSI against SHA256SUMS.txt. A firewall defect can interrupt networking or weaken host isolation.

Remove TinyWall and reboot first. Existing SecureWall installations need full removal before this version; in-place upgrades and repair are unsupported. Service loss can leave external networking blocked, including DNS and DHCP. Keep local console access.
