Secure plant to cloud
With the DataHub IoT Gateway you never need Internet access on the plant network. Using the DataHub within a DMZ means no inbound firewall ports on either the plant network or the cloud.The DataHub on the plant network provides an outbound connection to the DMZ, and the DataHub on the DMZ uses an outbound MQTT connection to send data to the cloud.
