OT security monitoring with zero production interruptions
In this illustrative example, 6 specialists would deploy passive OT monitoring across an energy company’s plant networks in 8 months. Visibility would reach 100%, with zero production interruptions.

100%
plant network visibility
In short
Case E-01 is an illustrative example the OT and SCADA security-monitoring programme a Remote Pro Ai squad would deliver for an energy company in Saudi Arabia’s Eastern Province. 6 specialists would deploy passive monitoring across plant networks, would implement IEC 62443 zones and would feed OT alerts into the corporate SOC. The result would be 100% plant network visibility with zero production interruptions.
In this illustrative example, an Eastern Province energy company needs eyes on its OT networks without touching production. 6 specialists would deliver in 8 months.
Every plant device visible, not one hour lost

Model
Ready Squad (Squad-in-4)
Data pattern
Client plant and corporate networks only
Stack
Passive OT sensors (Modbus, DNP3, IEC 61850, OPC UA inspection) · network TAP and SPAN · OT asset inventory · industrial firewalls · SIEM integration · Grafana reporting
Assembled in
4 working days; plant inductions completed in week 2
Decades of plant networks, and no complete map
In this example, the plant networks have grown over decades, with controllers, HMIs and engineering workstations from many vendors on largely flat segments. There is no complete asset inventory, and the corporate SOC cannot see OT traffic at all.
- Active scanning is ruled out
- one malformed packet could trip a controller and stop production. Visibility has to come from listening only, with every change made inside planned windows and under the plant’s permit-to-work process.
- Passive monitoring only; no active scans on control networks
- No production interruption, planned or unplanned
- IEC 62443 zones and conduits defined and enforced
- OT alerts handled by the existing corporate SOC
6 specialists, assembled in 4 working days
| Role | Level | Count | Location |
|---|---|---|---|
| OT security lead | Lead | 1 | Al-Khobar, on-site |
| OT security engineers | Senior | 2 | Al-Khobar, on-site |
| Network security engineer | Senior | 1 | Al-Khobar |
| SIEM and SOC integration engineer | Senior | 1 | Cairo |
| GRC specialist, IEC 62443 | Senior | 1 | Cairo |
Al-Khobar sits a short drive from the plants, so on-site engineers would join without relocation and complete site safety inductions in week 2.
Listen first, zone second, alert third
Weeks 1–3
Site surveys, safety inductions and validation of network diagrams against what was actually installed.
Months 1–3
Passive sensors connected through TAP and SPAN ports in planned windows; asset inventory built from observed traffic.
Months 4–6
IEC 62443 zones and conduits designed with plant engineering; firewall rules staged in monitor mode before enforcement.
Months 6–8
OT alerts integrated into the corporate SOC, playbooks written, reporting live and hand-over complete.
- Operating rhythm
- 2-week sprints · weekly executive report to the OT security manager every Friday · monthly steering with plant engineering · continuity target: zero unplanned turnover across 8 months.

- These figures are illustrative
- they show the kind of result this squad model is built to deliver, not a verifiable named-client record. Visibility is the share of plant network segments with a passive sensor and an inventoried asset list, confirmed against plant diagrams. Zone implementation was accepted by plant engineering per zone. Production interruptions are counted from the plant’s operations log over the full engagement.
About this case
Illustrative example
No client quote: this is an illustrative example
This is an illustrative example. No client is named, and the figures show the kind of result this squad model delivers, not a verifiable named-client record. On a scoping call you can ask for a reference under NDA from a comparable engagement, subject to that client’s consent.
Compliance this squad would handle
- IEC 62443 zones and conduits, with documented security levels per zone
- Passive-only monitoring under the plant’s permit-to-work procedures
- Supplier cybersecurity controls aligned to the operator’s third-party requirements
- OT alert triage and escalation integrated into the corporate SOC runbooks

Industrial controllers can fail on unexpected traffic, and a failed controller can stop production. Passive sensors only listen to copies of network traffic from TAP and SPAN ports, so they identify devices and protocols without sending anything to the control network. That is how Case E-01 is designed to reach full visibility with zero interruptions.
The squad would design zones and conduits with plant engineering, then stage every firewall rule in monitor mode first. Rules move to enforcement only after traffic logs confirm nothing legitimate would be blocked. Each zone is accepted individually, and every change runs inside a planned window under the plant’s permit-to-work process.
The existing corporate SOC. Case E-01 feeds OT alerts into the same SIEM and adds OT-specific playbooks, so analysts triage plant events with the same tools and escalation paths they already use. The squad would train the SOC team on OT protocols and document when to call plant engineering.
The OT security lead and 2 OT security engineers would work on-site from Al-Khobar and complete the plant’s safety inductions in week 2. Every sensor connection and firewall change runs inside a planned window under the permit-to-work process, with plant engineering present. Work from Cairo covers SIEM integration and IEC 62443 documentation, so fewer people need site access.
The programme would follow IEC 62443 for zones, conduits and security levels, the plant’s own permit-to-work and change procedures, and the operator’s third-party cybersecurity requirements for suppliers. Controls are documented zone by zone and accepted by plant engineering. Remote Pro Ai’s own certification status is published separately in the Trust Center and is not implied by this example.
