Overview
Operational Technology (OT) and Industrial Control Systems (ICS) in Canada face growing cybersecurity threats. Critical sectors such as energy, manufacturing, transportation, and smart infrastructure require strong protection of ICS/OT systems to prevent operational disruptions, safety hazards, and regulatory non-compliance.
IEC 62443 provides a structured framework for ICS/OT cybersecurity, covering risk assessment, system security requirements, secure development lifecycle, and continuous monitoring. Conducting a security gap analysis helps organizations identify vulnerabilities and maintain compliance with industry standards.
Cyberintelsys, a CREST-accredited cybersecurity provider, delivers detailed security gap analysis and compliance verification aligned with IEC 62443 for Canadian organizations.
Importance of Security Gap Analysis
ICS/OT systems may include legacy devices, proprietary protocols, and high-availability processes. Security gaps can exist in PLCs, HMIs, SCADA servers, industrial networks, and IT-OT integration points.
Identify gaps impacting operational integrity, safety, or availability.
Ensure regulatory compliance with IEC 62443 standards.
Maintain operational continuity while mitigating vulnerabilities.
Strengthen overall cybersecurity posture.
Build confidence with regulators, partners, and stakeholders.
Cyberintelsys CREST-Accredited Gap Analysis Approach
Our approach combines technical evaluation, regulatory alignment, and practical ICS/OT expertise.
1. Asset Inventory & Mapping

Map communication flows between OT layers, IT systems, remote access, and cloud interfaces.
Define safe testing boundaries to prevent production disruption.
2. Security Gap Analysis
Evaluate system configurations, access controls, and firewall rules.
Assess industrial protocols including Modbus, DNP3, OPC, IEC 60870.
Review firmware, software, and patch levels for vulnerabilities.
Compare existing security controls against IEC 62443 requirements.
3. Compliance Verification
Conduct controlled testing to validate implemented security measures.
Assess network segmentation, device hardening, and remote access security.
Confirm operational continuity while testing critical processes.
4. Risk Evaluation & Prioritization
Analyze each gap for likelihood, operational impact, and safety implications.
Prioritize remediation based on regulatory compliance, criticality, and safety.
5. Reporting & Recommendations
