Simplewall Firewall Overview
simplewall is a free, open-source firewall tool for Windows that provides a simple, lightweight interface to the built-in Windows Filtering Platform (WFP). Rather than replacing the Windows firewall with a heavy third-party suite, it lets you easily control which applications are allowed to access the network, with a clear list of rules and a notification mode that prompts you when a new program tries to connect. It includes curated blocklists, supports detailed custom rules, and adds no background bloat. It appeals to users who want straightforward, transparent control over outbound and inbound connections. Because the download is a complete installer, Simplewall Firewall installs without needing a connection during setup. It exposes both outbound and inbound control and can log blocked connections, which helps you see exactly what a machine is trying to reach. You can reach the official Simplewall Firewall download from Github via the link on this page.
