Managed OT Support Services for Multi-Plant Operations
A unified operating model for OT security across every plant you run — continuous network monitoring, vendor-coordinated patching, and a 30-minute critical response SLA. Built on Potenza's Defense-in-Depth framework, aligned to NIST SP 800-82r3 and ISA/IEC 62443, and proven to reduce OT-related incidents by 60% in a multi-year cement industry engagement.
Why plants outgrow ad-hoc OT support
The support model you started with stops scaling around plant three
The patterns below come up in almost every scoping call we run with multi-plant operators. None of them are exotic — they are the predictable consequences of an OT support model that was built for one site and then asked to cover nine.
- Incidents don't happen during business hours
- A control network problem at 2 a.m. halts production. The on-call technician doesn't have the industrial background to triage it. By the time someone who does is on the phone, you've lost hours of throughput and a shift supervisor is writing an incident report you'll be answering questions about for a month.
- Multi-plant operations outgrow ad-hoc support
- One plant is manageable. Five plants need structure. Nine plants need an operating model. Every site has its own architecture history, its own documentation gaps, and its own definition of 'critical' — and your OT director isn't running security anymore, they're project-managing spreadsheets that never quite match between sites.
- Corporate audits keep finding the same gaps
- You already know the firmware on Line 4 is out of date. You already know VLAN-12 at the Phoenix site doesn't match the architecture standard. But the people who can fix those things are the same people keeping production running — so the remediation ticket sits in the backlog until the next audit reopens it.
How Potenza manages OT across multiple plants
One operating model across every site, every shift
Managed OT support is a services engagement, not a product. Potenza brings continuous monitoring, standards-aligned architecture, and a human-led response model under a single operating framework — so the same triage process, reporting cadence, and SLA definitions apply at every plant.
Continuous monitoring across your OT network
Active monitoring, industrial IDS, and AI/ML-based anomaly detection tuned to EtherNet/IP, Profinet, and Modbus traffic. Alerts route into a consistent triage process across every plant — not a different console for every site and a different definition of 'critical' at each one.
Aligned to NIST SP 800-82r3 and ISA/IEC 62443
Purdue Model architecture (Levels 0–5), IT/OT network segmentation with DMZ and Industrial Zones, Zero Trust principles, CVE/NVD-based vulnerability management, and vendor-coordinated patch management. Standards alignment is a structural property of the engagement, not a checkbox at audit time.
30-minute critical response with an engineer on call
Critical incidents route to an engineer with hands-on OT experience — documented resolution, Root Cause Analysis for every closed ticket, and a weekly activity summary every Monday. 5x8 NBD or 24/7/365 coverage depending on the risk profile of the plant.
What a managed OT engagement includes
Outcomes, on a predictable cadence
Every engagement produces the same core artifacts on the same schedule — so your audit team, your cyber-insurance renewal, and your board all see the same story without you assembling it by hand.
Activity summary every Monday
Structured log of remote troubleshooting tickets by severity and plant, configuration changes, firmware and security updates, proactive maintenance, and any equipment alerts investigated during the prior week.
Network performance report
Delivered within 10 business days of month-end. Covers network behavior, bottlenecks, peak load periods, link utilization trends, issue resolution log by severity and plant, and the full update & maintenance log for the month.
Strategic assessment
Delivered by April 15, July 15, October 15, and January 15. Covers Critical and High severity incidents, trend analysis, emerging risks, vendor escalations, and a forward-looking roadmap for the next quarter.
Documentation refresh
Delivered by July 15 and January 15. Updated network equipment inventory, server and IT asset inventory, topology diagrams (logical and physical, VLANs, routing, security zones), and IP addressing schemes by plant.
Vendor-coordinated patching
Firmware and security updates scheduled around your production calendar and coordinated with the equipment vendors themselves — so your team isn't the one negotiating compatibility matrices during a maintenance window.
24-month document retention
Every report, diagram, and incident summary kept on file for a minimum of 24 months, available without delay for audit and trend analysis purposes.
