NetSentryx PRO 🛡️

AI-Driven, High-Performance Real-Time Network Observability & Threat Detection Engine

NetSentryx PRO is a next-generation, event-driven network monitoring and threat intelligence platform. Combining rule-based signatures with a PyTorch Deep Autoencoder, it provides sub-10ms packet and netflow anomaly detection, automated multi-channel alerting (Slack, Discord, Email), and an interactive real-time SOC dashboard.

🏗️ System Architecture

The following flow diagram illustrates the data ingestion, real-time deep learning inference, alerting pipeline, and WebSocket visualization layer:

🚀 Key Features

⚡ Real-Time Traffic Ingestion: Aggregates packet frames into rich netflow summaries on the fly with minimal latency.
🧠 PyTorch Deep Autoencoder Anomaly Detection: Utilizes a lightweight PyTorch neural network (TrafficAutoencoder) to detect sophisticated zero-day exploits, scanning, or DDoS attacks based on multivariate feature reconstruction error.
📈 Zero-Manual-Training Startup: Features automated synthetic fitting and statistical threshold calibration (Mean + 3 * Std) during server startup, making it fully functional out of the box.
⏱️ Sub-10ms Inference Latency: Optimized inference pipeline ensures real-time evaluation of high-throughput packet flows.
📣 Multi-Channel Alert Dispatching: Asynchronously pushes detailed intrusion alerts to Slack webhooks, Discord webhooks, Custom HTTP APIs, and SMTP emails using FastAPI's BackgroundTasks.
📊 Interactive SOC Dashboard: Elegant, dark-mode dashboard powered by Tailwind CSS, Chart.js, and WebSockets for real-time visualization of throughput metrics and live threat feeds.

🛠️ Quickstart & Setup Guide

1. Prerequisites

Ensure you have Python 3.10+ installed. If capturing live network interfaces:

Windows: Install Npcap (select "Install Npcap in WinPcap API-compatible Mode").
Linux: Install libpcap-dev via sudo apt-get install libpcap-dev.

2. Installation

Clone the repository and install dependencies (using uv is highly recommended for faster installation):

# Clone the repository
git clone https://github.com/yourusername/netsentryx.git
cd netsentryx

# Create virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install requirements
pip install -r requirements.txt

3. Environment Setup (`.env`)

Create a .env file in the project root to configure notification credentials:

# Discord Configuration
DISCORD_ENABLED=true
DISCORD_WEBHOOK_URL="https://discord.com/api/webhooks/your-webhook-id/your-webhook-token"

# Slack Configuration
SLACK_ENABLED=true
SLACK_WEBHOOK_URL="https://hooks.slack.com/services/YOUR_WORKSPACE_ID/YOUR_CHANNEL_ID/YOUR_SECRET_TOKEN"

# SMTP Email Configuration
SMTP_ENABLED=true
SMTP_SERVER="smtp.gmail.com"
SMTP_PORT=587
SMTP_USERNAME="[email protected]"
SMTP_PASSWORD="your-app-password"
SMTP_FROM_EMAIL="[email protected]"
SMTP_TO_EMAIL="[email protected]"

4. Running the Platform

🧪 Simulation Mode (Includes synthetic traffic simulator)

python main.py --simulate

🌐 Live Sniffing Mode (Requires administrator/sudo privileges)
