Air-Gapped MQTT Broker & Industrial OT Edge Gateway
Engineered for critical industrial infrastructure, military, and pharmaceutical manufacturing facilities operating isolated Purdue Model Level 2 (Cell/Area) and Level 3 (Operations) networks without internet access.
Air-Gapped Architecture Highlights
- Zero Outbound Phone-Home: 100% offline operation with zero telemetry leakage and zero unsolicited network packets.
- Local Ed25519 Cryptographic Licensing: Licenses are validated using embedded asymmetric keys bound to hardware fingerprints without cloud dependencies.
- Co-Located Mosquitto / EMQX Broker: Run edge MQTT brokers directly on Linux IPCs, DIN-rail gateways, or Raspberry Pi 4/5.
- Persistent Disk WAL Buffer: Non-volatile Write-Ahead Log preserves telemetry across broker restarts and power outages.
