# Introduction

**Monarch** is an Arch Linux distribution based on **Omarchy**. It pairs the Niri desktop with Noctalia and provides a starting point for cybersecurity work. The full installation profile includes more applications and security tools; the reduced profile keeps the desktop with fewer optional packages.

## What Monarch provides

* **Security environments:** [PentestEnv](/basics/pentest-tools/pentestenv.md), a native graphical manager for Exegol and RF Swift environments.
* **Web testing tools:** Caido is available with the full software profile. Install Burp Suite Community or Professional through **Monarch Menu → Software → Cyber → Burpsuite**.
* **Nessus on demand:** Docker aliases can download and start a Nessus container after you provide your own activation code. Nessus is not installed or activated on a fresh system.
* **Terminal tools:** The full profile includes tools such as Termshark and Posting, alongside shell aliases for common workflows.
* **Windows VM on demand:** Create a Windows virtual machine through **Monarch Menu → Software → Windows**. See [Windows VM](/basics/windows-vm.md).

{% hint style="info" %}
Monarch is an Omarchy fork, but its Niri and Noctalia desktop differs from Omarchy's Hyprland and Quickshell setup. Use Monarch's guides for desktop shortcuts and configuration. The [Omarchy manual](https://omarchy.org/manual/) can provide background on shared concepts.
