Why OT cybersecurity matters in Saudi Arabia

Operational technology (OT) is the equipment that runs physical processes: PLCs, SCADA, HMIs, engineering workstations and safety systems. In Jubail, Ras Tanura and Dammam, these systems run petrochemical, power, water and manufacturing sites. An attack on OT can stop production or create a safety risk, not just a data loss.

Many OT networks were built to stay isolated. Over time they have been connected to corporate IT, vendor laptops and remote access tools. OT cybersecurity in Saudi Arabia is about controlling those connections without disturbing operations.

Waves Telecom has 10 years in cybersecurity and is a Fortinet Gold Partner. We help plant operators and their suppliers design segmentation, secure remote access and keep evidence for audits.

The Saudi rule behind it: NCA OTCC-1:2022

The NCA's Operational Technology Cybersecurity Controls (OTCC-1:2022) cover industrial control systems in critical facilities. They apply to government bodies and to private organisations that own, operate or host critical national infrastructure. The NCA encourages other organisations to adopt them too. Compliance with the NCA's Essential Cybersecurity Controls is a prerequisite.

OTCC has 4 domains, 23 subdomains, 47 main controls and 122 subcontrols. Each facility is given a level from L1, the most critical, to L3. The controls include separating OT from corporate networks with zones and a DMZ. Remote access must use MFA, be encrypted, time-limited and monitored. Sites also need an asset inventory, hardened workstations, and backup and incident response.

OTCC also tells organisations to confirm that applying a control will not disrupt operations. Suppliers feel the same pressure: Aramco's CCC includes an Operational Technology classification for third parties.

How Waves approaches OT security

Walk-down and inventory

We list OT assets, network links and remote access paths with your operations team, without touching live control logic.

Gap review against OTCC

We compare what we find with the OTCC controls for your facility level and agree priorities with you.

Segmentation design

We design zones, a DMZ and firewall rules between IT and OT, and plan changes for agreed maintenance windows.

Secure remote access

We replace open vendor connections with controlled access that uses MFA, time limits and logging.

Install and document

We install and configure the equipment and hand over drawings, rule sets and evidence for audits.

Frequently asked questions

Does OTCC apply to our plant?

OTCC applies to industrial control systems in critical facilities run by government bodies or by private organisations that own, operate or host critical national infrastructure. Other organisations are encouraged to adopt it. We can review your situation with you, but the NCA or your regulator confirms formal scope.

Will security work stop production?

It should not. OTCC itself asks organisations to confirm that controls will not disrupt operations. We start with passive review, agree every change with your operations team and schedule work in maintenance windows.

What is the difference between IT and OT security?

IT security protects data and office systems. OT security protects the equipment that controls physical processes, where uptime and safety come first. The tools overlap, but OT needs more careful change control.

Which products do you use?

We are a Fortinet Gold Partner and often use FortiGate firewalls, including rugged models, for segmentation. We also work with Cisco, Sophos and Microsoft. We choose based on your site and existing equipment.

We are a supplier, not an operator. Does OT security affect us?

It can. Aramco's CCC includes an Operational Technology classification for third parties. If your staff or tools connect to plant networks, expect your customer to check your controls.

Do you work on site in Jubail and Ras Tanura?

Yes. Our team is based in Al Khobar and works on site across the Eastern Province. We follow the site's permit and safety rules.
