Alternatives to TinyWall

Compare all

Software that can replace TinyWall for an important use case, and what changes if you switch.

  • simplewall

    Puts a plain list of programs in front of the Windows Filtering Platform, so you decide what is allowed online.

    simplewall is open source under GPL-3.0, uses a plain allow and block list over the Windows Filtering Platform, and includes a block list aimed at Windows telemetry.

  • Windows Firewall Control

    A tray tool that extends Windows Firewall with outbound connection prompts and quick filtering modes.

    FreeProprietaryWindows

    Windows Firewall Control also uses the built-in firewall without a driver, but prompts when unknown programs try to connect out and offers one-click filtering mode switching.

  • Fort Firewall

    Open-source per-application firewall for Windows built on its own filtering driver.

    Fort Firewall is open source with per-application, wildcard and parent-process rules plus bandwidth graphs, but installs its own standalone filtering driver unlike TinyWall.

  • Portmaster

    Shows every connection each application makes and lets you block any of them, with sensible defaults already set.

    Portmaster is open source and runs on Windows and Linux, showing every connection per app, but installs a kernel driver and charges for some features.

  • GlassWire

    Network monitor and firewall with a visual traffic history.

    GlassWire adds a visual network traffic history and connection alerts on Windows and Android, but it is closed source and several features need a paid licence.
