Three parts to one service: a gateway that collects field telemetry, a cloud platform that shows it, and the secure connectivity that ties them together — so utilities can watch their OT assets remotely.
The Nexdane Cloud Gateway collects telemetry from field devices over Modbus and IEC 60870-5-104, buffers it, and forwards it securely to the Nexdane cloud. It is the piece that gets substation and RTU data off-site — without the customer having to build and run their own collection infrastructure.
GridSync is the web dashboard where the collected telemetry lands. Live and historical views of every connected site, alarm notifications, and an API to push the readings into the customer's own systems — reachable from anywhere, nothing to install on the operator's side.
The connection between a gateway and the cloud is the sensitive part, so we keep it narrow. Every link is encrypted and outbound-only, with per-site credentials and no listening services on the customer's OT network — aligned with IEC 62443 principles for remote connectivity.
Our engineering team works alongside your operations staff to ensure seamless deployment and ongoing reliability.
We map the field devices at each site, the protocols in play (Modbus, IEC 60870-5-104), and exactly which readings you want in the cloud.
We install and configure the gateway, connect it to the cloud, and verify each tag is flowing correctly before the site goes live.
Optional: we keep an eye on the incoming telemetry and alert you when a gateway drops off or a reading moves outside its expected range.
Our solutions engineers can walk you through the platform capabilities relevant to your specific environment and requirements.
