+title: What is Intrudex?
+hide:
+  - navigation
+---
+
+**Intrudex** is a *comprehensive*, **lightweight** intrusion detection and prevention system (**IDPS**) specifically designed for **Windows environments**. Leveraging the power of [*Sigma rules*](https://sigmahq.io/)—a community-driven standard for describing log events—Intrudex continuously monitors **Windows Event Logs** to identify *suspicious activity*, *potential threats*, and *indicators of compromise*.
+
+## **_Key Features_**
+
+-  **Real-Time Threat Detection:** Monitors Windows Event Logs and applies [*Sigma rules*](https://sigmahq.io/) to detect suspicious activity as it happens.
+-  **Modular Architecture:** Flexible design suitable for both individuals and organizations, allowing easy customization and extension.
+-  **Web Dashboard:** Centralized monitoring and management via a user-friendly [*Flask-based dashboard*](https://flask.palletsprojects.com/).
+-  **Self-Healing Mechanisms:** Ensures persistent protection, even against attempts to disable or tamper with the system.
+
+---
+
+## **_How It Works_**
+
+1.  **Log Collection:** Continuously gathers *Windows Event Logs* from the endpoint.
+2.  **Sigma Rule Application:** Transforms raw log data into *meaningful alerts* using community-driven [Sigma rules](https://sigmahq.io/).
+3.  **Threat Analysis:** Evaluates alerts to determine the severity and nature of detected threats.
+4.  **Centralized Monitoring:** Presents all alerts and findings in a web dashboard for easy review and management.
+
+---
+
+## **_Project Background_**
+
+Intrudex was originally developed as a *Final Year Project* for the **BS Digital Forensics and Cybersecurity** program.  
+The goal: bridge the gap between *advanced threat detection techniques* and *practical, effective defense* for Windows endpoints.
+
+---
+
+## **_Why Choose Intrudex?_**
+
+-  **Lightweight:** Minimal resource usage, ideal for endpoints.
+-  **Community-Driven:** Utilizes [*Sigma rules*](https://sigmahq.io/), benefiting from ongoing contributions and updates.
+-  **Practical Defense:** Focuses on *actionable alerts* to keep systems secure.
+-  **Easy to Use:** Simple setup and intuitive dashboard for monitoring and management.
+
+---
