# Secure Enterprise Content Management with Hexnode

In an enterprise environment managing upwards of 500,000 devices, maintaining the integrity of corporate data is a critical challenge. Hexnode UEM utilizes a **Secure Container** approach to bridge the gap between high-scale file distribution and stringent Data Loss Prevention (DLP).

This guide covers the setup of Hexnode’s Content Orchestration engine, the implementation of platform-native containers, and the enforcement of kernel-level security policies.

**System Architecture: The “Fenced” Environment**
-------------------------------------------------

Hexnode operates a virtualized environment that isolates corporate binary data from the personal user space. The architecture is divided into four critical layers:

- **The Repository Layer**: A Dedicated Cluster serves as the central “Source of Truth” for encrypted files. These files are replicated to regional **DAFS Nodes** to ensure low-latency access globally.
- **The Delivery Path**: Metadata and commands travel via the **MQTT Channel**, while the heavy data fulfillment occurs over the **local LAN**, preventing WAN saturation during massive rollouts.
- **The Sandbox Layer**: On the device, the Hexnode Agent manages the Secure Container—utilizing **Managed Apple Accounts** for Apple devices and Work Profiles for Android.
- **The DLP Monitor**: A kernel-level monitor that intercepts system calls related to the clipboard, screen capturing, and sharing to prevent data exfiltration.

**The Secure Content Container**
--------------------------------

Hexnode leverages platform-native technology to silo corporate data without compromising the user experience.

### **Apple Managed Account (iOS/macOS)**

Hexnode controls the flow of documents between applications. Work-related documents are restricted to “Managed” apps. This prevents a user from opening a corporate PDF in a personal social media app or a non-approved cloud storage account.

### **Android Work Profile**

On Android, Hexnode creates a physically encrypted partition. Corporate files remain invisible to personal applications, providing a clean “Air-Gap” within the same device.

**Managed Content Distribution (DAFS)**
---------------------------------------

Distributing large files (2GB+ manuals or videos) to half a million devices requires an optimized delivery mechanism. Hexnode uses the DAFS Overlay:

1. **Local Fulfillment**: Devices prioritize pulling content from regional DAFS nodes via the local network. This preserves bandwidth for other mission-critical operations.
2. **Version Parity**: The system enforces version control, ensuring every user across the global fleet has the most recent version of a document while legacy files are automatically purged.

**Data Loss Prevention (DLP) Matrix**
-------------------------------------

Use the following policies to “fence” your corporate data stream:

----------------------------

Before deploying content to your fleet, ensure the following steps are completed:

- **Upload Corporate Root Certificates**: Essential for secure document signing and identity verification.
- **Map Document Categories**: Assign specific files to the appropriate Organizational Units (OUs) or sub-companies.
- **Define Managed Open-In Rules**: Configure your iOS/macOS fleet to restrict data movement between apps.
- **Configure DAFS Cache Warming**: Pre-stage large media files on regional nodes to prepare for high-scale distribution.

 Note: 
The DLP Monitor operates at the kernel level. Ensure that your Hexnode Agent is updated to the latest version across all endpoints to maintain compatibility with recent OS security patches.
