portmaster VS cloneable

There's a very good relatively new open-source GUI firewall app like this called Portmaster:

https://safing.io/

It's available for Windows and Linux

You can get your own firewall app. Portmaster by safing.io lets you open and close what ever ports you want on your windows system

amazing work OP! what's the difference between zen and portmaster? :) i would like to compare options to see which one fits my needs the best way

For Context: Technical Introduction from https://github.com/safing/portmaster#technical-introduction

Portmaster is a privacy suite for your Windows and Linux desktop.

Base Technology

- Portmaster integrates into network stack using nfqueue on Linux and a kernel driver (WFP) on Windows.

- Packets are intercepted at the raw packet level - every packet is seen and can be stopped.

- Ownership of connections is found using eBPF and `/proc` on Linux and a kernel driver and the IP Helper API (`iphlpapi.dll`) on Windows.

- Most settings can be defined per app, which can be matched in different ways.

- Support for special processes with weird or concealed paths/actors:

--- Snap, AppImage and Script support on Linux

--- Windows Store apps and svchost.exe system services support on Windows

- Everything is 100% local on your device. (except the SPN, naturally)

--- Updates are fully signed and downloaded automatically.

--- Intelligence data (block lists, geoip) is downloaded and applied automatically.

- The Portmaster Core Service runs as a system service, the UI elements (App, Notifier) run in user context.

- The main UI still uses electron as a wrapper :/ - but this will change in the future. You can also open the UI in the browser

Feature: Secure DNS

- Portmaster intercepts "astray" DNS queries and reroutes them to itself for seamless integration.

- DNS queries are resolved by the default or configured DoT/DoH resolvers.

- Full support for split horizon and horizon validation to defend against rebinding attacks.

Feature: Privacy Filter

- Define allowed network scopes: Localhost, LAN, Internet, P2P, Inbound.

- Easy rules based on Internet entities: Domain, IP, Country and more.

- Filter Lists block common malware, ad, tracker domains etc.

Feature: Network History ($)

- Record connections and their details in a local database and search all of it later

- Auto-delete old history or delete on demand

Feature: Bandwidth Visibility ($)

- Monitor bandwidth usage per connection and app

Feature: SPN - Safing Privacy Network ($)

- A Privacy Network aimed at use cases "between" VPN and Tor.

- Uses onion encryption over multiple hops just like Tor.

- Routes are chosen to cover most distance within the network to increase privacy.

- Exits are chosen near the destination server. This automatically geo-unblocks in many cases.

- Exclude apps and domains/entities from using SPN.

- Change routing algorithm and focus per app.

- Nodes are hosted by Safing (company behind Portmaster) and the community.

- Speeds are pretty decent (>100MBit/s).

Portmaster itself is open source (https://github.com/safing/portmaster)

Then install https://safing.io/ (Portmaster); it's free.

I just mirrored every one of the following projects using my little utility cloneable.

I use it to backup all if my github repositories and update them in parallel.
