Critical Infrastructure Telemetry
Telemetry sealed at the device, health checks the operator can verify, and the grid map stays inside the operator's perimeter.
The problem to solve
National grid operators, water utilities, transport networks, and other operators of essential services covered by the NIS2 Directive need real-time telemetry from thousands of physical assets. IEC 61850 substation messages, DNP3 SCADA points, and vendor maintenance feeds typically traverse cloud or vendor-managed infrastructure where topology and operational state become visible to support contractors, third-party analytics platforms, and any compromised endpoint. The same telemetry that keeps the lights on or the water flowing becomes a map of national infrastructure for any adversary that gets the feed — and IEC 62443 zone/conduit segregation alone doesn't address what intermediaries see in transit.
The solution it enables
Polymonial seals telemetry at the device. The operator verifies health checks as ranges — voltage in range, frequency in range, temperature below threshold — without the topology or asset identities leaving its perimeter. Networks in between carry it encrypted.
What it looks like
A grid operator monitors thousands of substations. Each substation seals its telemetry at the device, and central control verifies each one's health checks. The networks in between carry it encrypted, and the grid map stays with the operator.
“The lights stay on. The grid map stays inside the operator.”
