Correct - IoT Hub Device Streams "A device stream is mediated by an IoT Hub streaming endpoint which acts as a proxy between your device and service endpoints. This setup, depicted in the diagram below, is especially useful when devices are behind a network firewall or reside inside of a private network." https://learn.microsoft.com/en-us/azure/iot-hub/iot-hub-device-streams-overview#device-stream-workflows
