Why GADNET?
Traditional routers leave your network vulnerable. GADNET changes that.
Traditional Routers Trust Everything
Every device on your network has immediate access to the internet and other devices. A compromised smart bulb can access your laptop.
Zero Trust by Default
Every new device is automatically isolated with no network access until you explicitly authorize it. Complete control over your network.
Complex Configuration
Setting up VLANs, firewall rules, and security policies requires networking expertise and hours of configuration.
15-Minute Automated Setup
Flash the SD card, boot your Linux device, and GADNET configures everything automatically. No technical knowledge needed.
No Visibility into Threats
You have no idea what's happening on your network until something goes wrong. Threats go undetected for days or weeks.
AI-Powered Security Monitoring
Real-time threat detection with machine learning. Get instant alerts about suspicious activity and automated threat response.
Cloud Dependencies
Your router sends data to the manufacturer's cloud. Privacy concerns, vendor lock-in, and service disruptions.
Self-Hosted & Private
Everything runs locally on your device. No cloud, no telemetry, no data collection. You own your network data.
