Project Introduction

Summary

This project implements a proof-of-concept for a performant, secure, and easy-to-manage overlay network, providing a unified address space and encrypted communication across diverse physical networks or cloud providers.

Problem Solved

Traditional network configurations like VPNs, complex routing tables, or firewall rules become unmanageable and insecure in dynamic, distributed, or multi-cloud environments. This project offers a secure, flat network layer over existing infrastructure.

Core Features

Peer-to-Peer Connectivity

Establishes direct, encrypted connections between individual hosts, bypassing traditional routing complexities.

Built-in Encryption

All network traffic is automatically encrypted end-to-end using strong cryptographic primitives.

Simple Configuration

Configuration is simplified via a central authority or distributed file, making onboarding new hosts straightforward.

Tech Stack

Go
Cryptography
Networking Protocols
Operating System Kernels

Use Cases

This overlay network solution is ideal for various scenarios requiring secure, simple, and scalable connectivity across different locations or environments.

Connecting Heterogeneous Environments

Details

Connect servers, containers, and services running in different cloud provider VPCs or on-premises data centers as if they were on the same local network.

User Value

Simplifies cross-environment communication and management, reducing network complexity.

Secure Remote Access

Details

Provide secure access for remote employees or devices to internal resources without requiring a traditional, centralized VPN concentrator.

User Value

Enhances security with end-to-end encryption and simplifies remote connectivity setup.

IoT Device Networking

Details

Establish secure communication channels between geographically dispersed IoT devices and central management platforms.

User Value

Provides a secure, scalable, and direct communication method for scattered devices.
