Service Framework

Four Engineering Pillars

Framework-driven OT cybersecurity services engineered for industrial availability, process safety, and regional regulatory compliance — not IT data confidentiality.

01

OT Cyber Assessment & Risk Governance

Know your exposure before the adversary does.

ISA/IEC 62443-2-1IEC 62443-3-2NIST SP 800-82 Rev 3Saudi NCA ECC-1:2018

Consequence-driven risk quantification rooted in physical process analysis. Our assessments map cyber vulnerabilities directly to HAZOP/LOPA safety consequences, exposing risks that purely IT-centric methodologies miss entirely.

  • Passive asset visibility mapping — zero active probes on live loops
  • HAZOP/LOPA cyber-mapping for consequence-driven risk scoring
  • Purdue Model Layer 0–4 gap analysis against IEC 62443-3-2 SL targets
  • Regulatory compliance gap analysis: NESA, CITRA, NCA ECC, DESC
  • Network architecture review and zone/conduit boundary validation
  • Third-party vendor and supply chain risk exposure assessment
02

Turnkey Architecture & Segmentation Engineering

Defending the Purdue Model from Layer 0 to the enterprise boundary.

ISA/IEC 62443-3-3ISA/IEC 62443-4-1ISA/IEC 62443-4-2

Engineering-led implementation of zone and conduit architectures across the full Purdue Model hierarchy. We install hardware-enforced boundaries that physically prevent lateral movement between OT and IT networks — with deep packet inspection tuned for industrial protocols.

  • Custom zone/conduit segmentation engineering (IEC 62443-3-3 compliant)
  • Hardware-enforced unidirectional security gateways (data diodes)
  • Industrial firewall DPI for Modbus TCP, OPC UA, DNP3, Profinet, EtherNet/IP
  • Industrial DMZ design between Layer 3 (Ops Management) and Layer 4 (Enterprise IT)
  • Legacy HMI, RTU, and EWS endpoint hardening without process disruption
  • FAT/SAT security testing and commissioning sign-off
03

Managed OT Monitoring & Resilient Response

Continuous operational awareness — without active probing risk.

NIST CSF (Identify, Protect, Detect, Respond, Recover)ISA/IEC 62443-3-3 SR 6

100% passive deep packet inspection monitoring that baselines normal industrial communication patterns and flags anomalies without ever injecting a single malformed query into the field network. OT-specific SIEM/SOC integrations designed around process safety, not data confidentiality.

  • Passive DPI network monitoring — no active scanning on live control systems
  • Industrial SIEM/SOC integration with OT-native detection platforms
  • Process baseline anomaly tracking and behavioral drift detection
  • Serialized asset inventory with firmware version and CVE correlation
  • OT-specific Incident Response Plan (IRP) engineering for plant-trip mitigation
  • 24/7 alert triage by engineers with ICS/SCADA operational backgrounds
04

Specialized Industrial Workforce Training

Building operational defense intelligence at every role level.

ISA/IEC 62443 Cybersecurity FundamentalsISA/IEC 62443 Specialist Track

Role-bifurcated training programs that recognize OT engineers and IT security teams operate in fundamentally different threat environments. Automation engineers learn PLC/SCADA defense while IT teams learn the hard rules of safe OT engagement — preventing the most common source of OT incidents: well-intentioned IT actions on live systems.

  • Automation Engineers track: PLC/DCS/SCADA threat vector defense
  • IT Security teams track: OT environment engagement safety protocols
  • Layer 1/2 control logic threat vector workshops and live lab exercises
  • ICS/SCADA incident tabletop simulations with process consequence scenarios
  • NCA, NESA, and IEC 62443 compliance readiness workshops
  • ISA/IEC 62443 Cybersecurity Fundamentals & Specialist certification prep
