A Little Snitch for Windows
PacketHound is a Windows firewall tool that asks for permission before any app attempts to connect to the internet. It turns the default Windows Firewall setting for outgoing connections to block, requiring user approval for new connections. Each app is identified by its executable path and publisher, even if it's a part of Windows like PowerShell, curl, or certutil.
Users can allow or block specific destinations for each app, with decisions remembered indefinitely or until the app is closed. PacketHound integrates with the existing Windows Firewall, keeping prompts unobtrusive and easily manageable. It logs all blocked attempts and offers a privacy-friendly service, checking for updates once a week without collecting user data.
The software is free, open-source, and compatible with Windows 10 and 11, requiring no additional drivers or background services.
