Fort Firewall 3.20.6 has been released, introducing an "Ask to Connect" filter mode that requires user approval before programs can connect to the network. This open-source firewall operates independently from Microsoft Defender Firewall and is managed by solo developer Nodir Temirkhodjaev. However, users must disable Windows Memory Integrity (HVCI) on Windows 10 and later to use Fort, which poses a security trade-off. Despite this, the firewall offers extensive features, including per-application control, customizable connection prompts, and local data storage, making it appealing for privacy-focused users

Fort Firewall 3.20.6 Adds Ask to Connect Prompt

Fort Firewall 3.20.6 released today, adding an "Ask to Connect" filter mode that pauses a program's connection until you approve it. The solo-developer, GPL-3.0 firewall runs its own signed kernel-mode WFP driver and stands independent of Microsoft Defender Firewall. The catch is that Fort requires turning off Windows Memory Integrity (HVCI) on Windows 10 and later, a real security trade-off worth considering before installing.
