Featured on Unplugged — An IIoT Podcast
The open publish/subscribe standard that connects the plant floor to the enterprise and the cloud — built by the team that pioneered MQTT infrastructure for industrial IoT.

If you work in industrial automation, you have a connectivity problem: getting reliable, secure, real-time data off the plant floor and into the systems that need it — without brittle polling, proprietary protocols, or vendor lock-in.
Cirrus Link solved that problem by co-authoring MQTT Sparkplug — the open specification that brought a lightweight, report-by-exception, publish/subscribe model to industrial data. It's now the connective tissue for a huge share of modern IIoT architectures, and it's exactly the OT/IT crossover the Unplugged community lives in.
The platform, explained
Brings MQTT and Sparkplug data natively into your SCADA/HMI platform — auto-discovering tags from edge devices publishing to the broker, with no manual mapping.
Publishes plant-floor tag data to any MQTT broker using the Sparkplug specification — report-by-exception, stateful, and efficient over constrained or intermittent links.
A built-in Sparkplug-aware broker plus native injectors for AWS, Azure, and Google Cloud — moving OT data to the enterprise and cloud with security and scale.
Proof points
Cirrus Link's modules are the reference implementation for MQTT Sparkplug in industrial automation — powering report-by-exception data pipelines from the edge to the enterprise across manufacturing, energy, oil & gas, and utilities.
