Cloak the plant floor. Keep production talking.
CloakNet gives OT and IoT estates the connectivity they need — remote engineering, telemetry, cloud reporting — without exposing a single controller, sensor or HMI to the internet.
OT wasn't built for the internet — but it's connected to it anyway
Legacy protocols with no authentication, decades-old firmware, vendor VPNs punched through the firewall, and cellular modems bolted onto machines. Every connection convenience is an attacker's beachhead into physical processes.
Unauthenticated protocols
Modbus, serial and vendor protocols will answer anyone who can reach them. The only safe posture is making them unreachable.
Vendor & contractor access
Every OEM wants a tunnel to "their" machine. Shared VPNs and TeamViewer boxes become unmanaged backdoors.
Cloud data demands
Analytics and IIoT platforms need field telemetry — pushing teams to expose data paths from networks that should stay isolated.
Least-privilege access to assets that stay invisible
- Asset cloaking: PLCs, RTUs, HMIs and gateways have no inbound path — they're reached only through the authenticated overlay
- Per-asset, per-identity access: a vendor engineer gets one PLC, one protocol, one time window — never the network
- Purdue-friendly: deploy at Level 3/3.5 without re-architecting cell networks or flattening zones
- Telemetry without exposure: Modbus RTU/TCP collected at the edge and published to MQTT/cloud over outbound-only tunnels
- Session recording & audit: every remote access is identity-stamped and logged

Purpose-built industrial routers for the last meter
The CloakNet CN350W-4G connects field equipment over dual-SIM 4G LTE, speaks RS232/RS485 and Modbus to PLCs, meters and sensors, and reports to your cloud over MQTT — all inside a −30 °C to 75 °C metal casing with ESD and surge protection.

Built for the environments that can't go down
Manufacturing
Secure PLC remote debugging, OEE data collection and vendor maintenance access across plants.
Energy & utilities
Substation, solar and water telemetry from remote sites over cellular — with no reachable endpoints.
Smart infrastructure
Kiosks, EV chargers, surveillance and building automation managed at fleet scale from one policy plane.
Give OT the isolation it deserves
We'll demo cloaked PLC access and cellular telemetry end to end.
