Why can't our automation OEM be the OT Service Owner?

Because the party that supplies the equipment has a product roadmap to protect, and the party that governs security has to be free to recommend against it. Structural independence is not a judgment of any vendor; it is a separation of roles, the same reason auditors do not keep the books.

What does the Service Owner need from us to start?

A topology of record for at least one plant (the Topology Assessment produces it), a named counterpart on the operator side, and authority over remote-access policy. The governance model then extends plant by plant.

Is this a full-time person on site?

It is a named, accountable role with defined ITIL-aligned responsibilities, backed by Potenza's engineering team, not a single individual's calendar. On-site presence is scheduled around assessments, outages, and audits.

OT Service Owner for Cement Plants

One accountable owner for OT security across every cement plant you run, independent of the OEMs whose equipment is on the network, holding the roadmap for a fleet that is mostly past vendor support.

What is specific to cement

When three vendors hold the fleet, independence is the control.

Cement plants run on a concentrated installed base. In the assessed fleet, three vendors accounted for roughly three-quarters of the switches. When the same vendors also propose the security roadmap, the operator loses leverage over its own modernization spend. The OT Service Owner exists to keep that leverage on the operator's side.

01Owns the End-of-Life roadmap: With most of the switching fleet outside vendor support, the largest OT security decision a cement operator makes is the replacement sequence. The Service Owner holds that roadmap, prioritized by production criticality and exposure, and not anchored to any single vendor's catalog.
02Governs OEM and integrator remote access: Kiln, mill, and packing OEMs each have support paths into the plant. The Service Owner brokers, logs, and expires that access under one policy across all plants, so an integrator's VPN from a 2019 project is no longer an open door in 2026.
03Reports posture in the operator's terms: Fleet-wide risk posture is reported per plant and per production area against the Cement & Mining OT Baseline: inventory of record, topology of record, Purdue-aligned segmentation, governed access, independent governance. Progress is visible to plant management and corporate alike.
