A Little Snitch for Windows

PacketHound is a free Windows firewall tool that monitors outgoing internet connections and asks users to allow or block each app's first connection attempt, remembering their choices. It filters out system components to avoid excessive prompts while still monitoring potentially risky Windows tools like PowerShell and certutil that malware commonly exploits. Built on Windows' native firewall without requiring kernel drivers, it provides users with clear visibility into which applications are attempting to contact the internet and full control over those connections.
