The Biggest Challenges for IT Accessing OT Data

Security, reliability, and multi-protocol support

    The Biggest Challenges for IT Accessing OT Data

    Security requires complete segregation of OT and IT networks using a DMZ.  All inbound firewall ports must stay closed.  Unlike a VPN, this ensures that any attack on IT does not propagate to OT.  The NIS2 Directive and NIST CSF 2.0 mandate this level of  full network segmentation.

    Reliability means preserving connectivity, keeping data consistent, and fully recovering from any network outages. Data must remain consistent from source to user, even through a DMZ.

    Multiple-protocol support is needed to combine the advantages of OPC UA and MQTT while connecting other protocols like Modbus, ODBC, and OPC Classic in the plant.  On the IT side, the data feed should connect seamlessly to historians, data lakes and cloud services.
