A Saudi OT Security Partner Built Around NCA Controls

As the Kingdom expands its industrial base under Vision 2030, OT and ICS environments—across energy, petrochemicals, power, water, and mining—carry both enormous value and concentrated risk. Weaknesses in segmentation, remote access, identity, or unmanaged assets open pathways with real operational and national consequence. Saudi operators need a partner fluent in both the plant floor and the National Cybersecurity Authority’s controls.

Arista Cyber delivers engineering-led OT/ICS cybersecurity services aligned to the IEC 62443 framework and the NCA’s Operational Technology Cybersecurity Controls (OTCC), informed by NIST SP 800-82 and the Purdue Model. We prioritise controls by consequence to safety, availability, and production, and deliver implementation-ready, audit-defensible outputs that deploy safely in live environments.

From a single facility to a Kingdom-wide multi-site program, we act as your engineering-led OT security advisor. New to the discipline? Begin with our complete guide to OT security.

Our Comprehensive OT Cybersecurity Services

A complete OT and ICS security lifecycle, from assessment to sustained operations, aligned to IEC 62443, the Purdue Model, and NIST SP 800-82, and delivered by engineers who work safely in live industrial environments.

1. Assessment & Analysis

Establish a defensible understanding of OT assets, communications, and risk exposure that directly impact safety, reliability, and production continuity.

We validate what is deployed across OT networks, including devices, applications, control layers, and supporting infrastructure, rather than relying on legacy diagrams or inherited assumptions. We analyze system-to-system communications to identify high-consequence pathways where a cyber event could propagate into operational disruption.

Outputs include a verified asset inventory, communications and dependency mapping, and a risk-ranked findings register aligned to operational consequence and asset criticality.

2. Secure Design & Deployment

Translate assessment findings into an OT-aligned architecture that supports operations, maintenance, and safety objectives.

We translate risk findings into IEC 62443-aligned architectures using practical zoning, conduits, and enforceable access controls. Designs account for vendor limitations, legacy platforms, and operational constraints, and include implementation guidance aligned to site governance, management of change (MoC), and planned maintenance windows.

Outputs include a target architecture package, zone and conduit model, boundary control requirements, and deployment steps structured for controlled execution.

3. Operate & Improve

Sustain security performance through continuous visibility, response readiness, and disciplined recovery.

OT environments evolve incrementally, but risk accumulates when visibility and controls remain static. We help organizations establish OT-relevant monitoring, consequence-aware incident response procedures that prioritize safety and availability, and repeatable recovery practices covering patch governance, backup integrity, and controlled system restart.

Outputs include monitoring design inputs, OT incident playbooks, recovery and restoration procedures, and operating routines that reduce decision latency during abnormal conditions.

4. Training & Transformation

Embed cybersecurity into daily operations through role-based capability and shared accountability.

Effective OT security depends on how teams make decisions during routine operations, maintenance, and incident conditions. We deliver role-specific training grounded in operational scenarios, focused on responsibilities, escalation paths, and practical trade-offs encountered in the field.

Outputs include role-based training sessions, operating guidance, and alignment across OT, IT, engineering, and leadership functions to strengthen coordination and reduce reliance on individual expertise.

OT Cybersecurity Compliance in Saudi Arabia

Saudi OT security is defined by the National Cybersecurity Authority’s controls and, for the energy supply chain, by Aramco’s cybersecurity standard, all mapping closely to IEC 62443. We align your program to the controls that govern your operation. For the framework foundation, see our guide to IEC 62443.

NCA OTCC (OTCC-1:2022)

The National Cybersecurity Authority’s Operational Technology Cybersecurity Controls are the Kingdom’s dedicated OT baseline. We assess against OTCC and build the architecture, controls, and evidence to meet it.

NCA ECC & CCC

The Essential Cybersecurity Controls and Critical Systems Cybersecurity Controls set organisation-wide and critical-systems requirements. We align OT programs so they satisfy these alongside OTCC.

Aramco SACS-002

Saudi Aramco’s Third Party Cybersecurity Standard (SACS-002) governs suppliers and contractors connecting to or serving Aramco. We help vendors and operators meet its requirements.

IEC 62443 & Vision 2030

IEC 62443 structures our program design and maps closely to NCA controls, giving Kingdom operators a globally recognised backbone as they scale industrial capacity under Vision 2030.

What Makes Us Different: Engineering-Led Delivery

We are an engineering-led OT security company with an implementation mindset, not a generalist IT firm applying IT playbooks to a plant floor. That difference shows up in every engagement.

Assessment-first, always

We start with structured diagnostics using IEC 62443 and risk-based methods to establish an accurate view of exposure, asset criticality, trusted pathways, and the most likely routes to loss of control or view.

Designed for real plants

Our recommendations account for legacy platforms, vendor limitations, strict change windows, and safety requirements. Solutions are enforceable in the field, not just documented in a report.

People and governance built in

We align OT, IT, engineering, and leadership around clear decision rights and role-based responsibilities, reducing execution friction and supporting resilience beyond a single project.

Built to scale, designed to fit

We support single-site improvements and multi-site programs with consistent standards alignment, while respecting the local operational realities of each site.

OT Security for Canada’s Critical Industries

We secure the OT and ICS environments where a cyber event becomes an operational one, loss of availability, safety exposure, or regulatory impact.

OT Cybersecurity Services in Saudi Arabia: FAQs

We are engineering-led and structure programs directly around the NCA’s OTCC and IEC 62443, while designing for the legacy platforms, safety constraints, and change windows of real plants. We serve energy, petrochemical, power, water, and mining operators across the Kingdom, and their supplier ecosystems.

Yes. We assess OT environments against the NCA’s Operational Technology Cybersecurity Controls (OTCC-1:2022) and align them with the Essential and Critical Systems Cybersecurity Controls (ECC and CCC), then build the architecture, controls, and evidence needed to meet them.

Yes. We help vendors, contractors, and operators connecting to or serving Saudi Aramco meet the Third Party Cybersecurity Standard (SACS-002), translating its requirements into concrete OT controls and demonstrable evidence.

IEC 62443 for program and zone/conduit design, NIST SP 800-82 for ICS guidance, and the Purdue Model for segmentation, mapped to NCA OTCC, ECC, and CCC, and to Aramco SACS-002 where the energy supply chain is involved.

Yes. We use passive monitoring methods and carefully selected monitoring points so visibility improves without introducing instability into control systems, essential for the high-availability, high-consequence environments across the Kingdom’s critical industries.
