simplewall v3.8.7 Free Download For Windows 11, 10, 8 and 7 [Latest Version]

simplewall for Windows is a lightweight, high-performance security utility for configuring the native Windows Filtering Platform (WFP) to monitor and control network activity on your PC. The Windows Filtering Platform provides a set of system-level APIs and kernel services for filtering network packets. By interfacing directly with WFP, simplewall lets you decide exactly which applications and services are permitted to access the internet. Importantly, simplewall is not a mere control panel or frontend for Windows Defender Firewall—it operates independently at the kernel level without altering standard Windows Firewall rules.

With its clean and intuitive interface, simplewall clearly displays all active applications with or without internet access, making connection management simple and transparent. It features versatile security profiles including Whitelist mode (default block), Blacklist mode, and custom rules. Built-in XML blocklists actively drop outbound packets to Microsoft diagnostic and telemetry endpoints, ensuring your system remains private and free from unwanted background data collection. Whether you choose the setup installer or the standalone portable edition, simplewall gives you complete, lightweight control over your PC's network traffic.
