🐈 CAT-CMS (Enterprise Cloud & ISP Ecosystem)

"Sovereign Infrastructure Automation | Single & Cluster Ready"

CAT-CMS is a high-performance, Linux-native management layer that unifies Web Hosting (Shared/VPS) and ISP Operations (Radius/MikroTik) into a single, automated ecosystem. Developed by Cyber Adversary Taskforce (CAT) Bangladesh, it is engineered to eliminate dependency on expensive foreign licenses like cPanel and WHMCS, saving millions in foreign currency outflow.

🚀 Vision: Digital Sovereignty & Economic Impact

The primary mission of CAT-CMS is to achieve Import Substitution. Currently, thousands of USD flow out of Bangladesh every month for server management and billing licenses. CAT-CMS provides a locally-built, enterprise-grade alternative that is:

• Cost Effective: 0% licensing fee, keeping capital within the country.
• Sovereign: Securely managed by local engineers under national security standards.
• Independent: No more reliance on global price hikes of legacy panels.

🛠 High-Level Architecture (The Engine)

CAT-CMS follows a Decoupled Hybrid Architecture for maximum security and scalability.

1. Application Layer: Symfony 7.x (Enterprise PHP Framework) — Handles Business Logic, Billing, API, and UI.
2. Data Layer: PostgreSQL 16+ — Robust transactional integrity and GIS support for mapping.
3. Execution Layer: cat-daemon (Golang) — A low-latency system agent running with root privileges to execute OS commands.
4. Web Server: OpenLiteSpeed — Native event-driven architecture for ultra-fast web performance.

 ## ⚙️ Core Technical Logic & Workflows

**1. Automated Lifecycle & Billing**
​The system uses an advanced Pro-rata Billing Logic:
​Activation Flow: User pays via bKash/Nagad/Upay/SSLCommerz → Payment Hook triggers Symfony Service → API Signal sent to cat-daemon → Service Provisioned (vHost or Radius account).
​Suspension Logic: A daily Cron Job checks PostgreSQL for overdue invoices. If Current Date > Due Date, the system automatically triggers a suspension command across the Web Cluster or MikroTik Edge nodes.
**​2. Multi-Node Scaling (Single vs. Cluster)**
​Single-Server Mode: Full stack (Web, DB, Panel) on one node—ideal for small ISPs.
​Cluster Mode: A Master Node manages multiple Agent Nodes via encrypted mTLS communication, allowing for massive scaling across data centers.
​**3. GIS Network Mapping (Google Maps)**
​Built-in integration with Google Maps API allows ISP owners to:
​Visualize fiber optic POP locations.
​Monitor real-time client outages on a map.
​Optimize technician deployment based on client clusters.

## ​📦 Deployment: The "One-Command" Install
CAT-CMS is designed to be installed via Cloud-init or a simple Bash script on a fresh Ubuntu 24.04 LTS server.
curl -sSL [https://catbangladesh.com/install.sh](https://catbangladesh.com/install.sh) | sudo bash

## 💰 Why Choose CAT-CMS? (The Import Substitution Factor)

The primary goal of CAT-CMS is to eliminate the heavy reliance on expensive foreign software licenses. Below is a direct comparison of why CAT-CMS is the superior choice for the local and global market:

| Feature | Legacy Foreign Stack (cPanel + WHMCS + Virtualizor) | CAT-CMS Enterprise Ecosystem |
| :--- | :--- | :--- |
| **Monthly Licensing** | $100 - $250+ USD (Recurring Outflow) | **$0 / Local Subscription (Saves Foreign Currency)** |
| **Core Architecture** | Legacy/Monolithic (Resource Heavy) | **Modern Symfony + Go (Ultra-Lightweight)** |
| **Web Server** | Apache/Nginx (Standard) | **OpenLiteSpeed (3x Faster Performance)** |
| **Local Payments** | Requires costly 3rd party plugins | **Native bKash, Nagad, Upay & SSLCommerz** |
| **Global Payments** | Standard (PayPal/Stripe) | **Native PayPal & Stripe Integration** |
| **ISP & Networking** | Not Supported (Requires Splynx/Radius) | **Built-in Radius Engine & MikroTik API** |
| **GIS Capability** | None | **Integrated Google Maps for Asset Tracking** |
| **Deployment** | Manual/Complex Installation | **One-Command Cloud-init Installation** |
| **Data Sovereignty** | Data managed by foreign entities | **100% Sovereign Data Control by CAT Bangladesh** |
