Minimal Firewall 2.2 Portable
Minimal Firewall is a portable Windows firewall frontend that alerts users to internet connections without requiring custom kernel modifications or disabling core isolation, striking a balance between Window Defender's security and Simplewall's functionality.
Minimal Firewall enhances the built-in Windows Firewall to block all unknown network connections by default, giving you complete control. It prompts you for action when an application tries to connect, allowing you to mitigate malware, stop unwanted telemetry, and prevent data leaks. With Minimal Firewall, no application «phones home» without your explicit permission.
Unlike most other Firewall programs, Minimal Firewall acts as a frontend, avoiding enlarging your computer's attack surface by playing around with lower levels of the WFP. Minimal Firewall also has an audit feature to examine new rules added to Windows Firewall. When you use a WFP app, it acts as a filter on top of Windows Firewall. The problem is that Microsoft sets varying levels of importance to its firewall rules (e.g. those changed in group policy editor or related to Windows Defender may have higher importance). So if the filter and Windows Firewall rules conflict, it's not clear which one supercedes the other. Minimal Firewall avoids this by working directly with Windows Firewall without having to shut off this key part of your Windows security.

Features
Lockdown Mode
The heart of Minimal Firewall. When enabled, it configures the Windows Firewall to block all outbound connections that don't have an explicit «Allow» rule. No program connects without your say-so.
Real-Time Connection Alerts
Get instant notifications when a blocked program attempts network access. Choose between interactive pop-ups for immediate action or silent, in-app alerts on the dashboard to review later.
Program Rules
Allow or block applications with a single click.
Advanced Rules
Create detailed rules based on protocol (TCP/UDP/ICMP), local/remote ports, IP addresses, services, and network profiles (Domain, Private, Public).
Firewall Auditing
The Audit tab shows you a log of firewall rules that were created, modified, or deleted by other applications, giving you visibility into background changes.
Live Traffic Monitoring
The «Live Connections» tab displays all active TCP connections on your system in real-time, showing which process is connected to which remote address.
Wildcard Rules
Easily manage applications that update frequently (like web browsers) by creating rules that apply to any executable within a specific folder.
Trust Publishers/Digital Certificates
This works similar to wildcard rules. You can automatically trust apps with digital certificates trusted by Windows. Or you can whitelist publishers yourself.
UWP & Service Support
Manage rules for modern Windows Store (UWP) apps and background system services, not just traditional desktop programs.
Light & Dark Themes
A clean, modern user interface that's easy on the eyes, day or night.
100% Local and Private
Minimal Firewall contains no telemetry, does not connect to the internet, and stores all rules and logs locally on your machine.
Portable
Minimal Firewall is a single executable that requires no installation. All rules are native to Windows Firewall, so no custom drivers or services are left behind.
