# Defendingo

> Defendingo is a network monitor for Windows and Linux that shows which apps on your computer go online, who they talk to (names and companies instead of IP numbers), and explains in plain words when something looks unusual. Built in Rust: the always-on guard uses about 16 MB of memory and a fraction of one percent of the processor.

Defendingo is for everyday people, gamers and IT-curious users who want to know what their apps do on the internet without being network experts. It watches and explains; it never blocks connections, ends programs or changes settings, so it can't break anything. History stays on the user's own computer for 90 days. No account, no ads, no tracking.

## Key facts

- Current version: 0.6.2
- Systems: Windows 11 and 10 (64-bit); Linux 64-bit (Ubuntu 22.04+, Debian 12+, Linux Mint 21+, Pop!_OS, Fedora 36+, Arch and others) with a .deb package and a portable folder. macOS: early access (sign up at https://defendingo.com/mac).
- What it shows: every program that connects to the internet, the website or company it reaches, a category (games, browser, system, delivery network, cloud server, known service, unknown), and plain-language warnings
- Warnings include: programs that aren't digitally signed (Windows) or weren't installed by the package manager (Linux), programs running from Downloads or temporary folders, connections to services malware often misuses (Telegram bots, Pastebin, ngrok, free dynamic DNS), programs other than Discord contacting Discord (token stealers), and ports used by remote-access trojans
- Run with Defendingo: right-click a program to start it and watch everything it and its helper programs do online, with a summary when it closes
- 90 days of searchable history, per-app overview and insights, all on the user's own computer
- Updates install automatically within about 15 minutes of a release, with nothing to download by hand; they are signed with an offline key, so a hacked website could not push a fake update
- Privacy: no account, no tracking; only anonymous daily totals (installs, system type, app version), which can be switched off
- Built in Rust for speed and memory safety; the website runs no scripts at all

## How it compares

- Compared with Wireshark: Wireshark shows raw network packets for experts. Defendingo shows which app talks to whom, in plain language, for everyone.
- Compared with netstat or Task Manager: those list numbers and addresses. Defendingo names the company behind each address, sorts connections into categories and explains what deserves a look.
- Compared with firewalls: a firewall blocks. Defendingo only watches and explains, so it never breaks games or apps, and it works alongside any firewall and antivirus.
