Overview
Industrial Control Systems (ICS) and Operational Technology (OT) environments in Canada face rising cyber threats targeting critical infrastructure. Industries such as energy, manufacturing, transportation, and smart cities require secure ICS/OT systems to prevent operational downtime, safety hazards, and regulatory non-compliance.
IEC 62443 provides a globally recognized framework for ICS/OT cybersecurity, including risk assessment, system security requirements, secure development lifecycle, and continuous monitoring. Compliance ensures protection of critical infrastructure and demonstrates cybersecurity diligence.
Cyberintelsys, a CREST-accredited cybersecurity company, delivers comprehensive Vulnerability Assessment (VA) and Penetration Testing (PT) services aligned with IEC 62443 in Canada. Our services help organizations identify, assess, and remediate cybersecurity risks while maintaining operational continuity.
Importance of VA/PT for IEC 62443
ICS/OT systems differ from traditional IT networks and often include legacy devices, proprietary protocols, and safety-critical processes. Vulnerabilities may exist in PLCs, HMIs, SCADA servers, industrial networks, remote access systems, and IT-OT integration points.
Identify critical vulnerabilities impacting safety, availability, or process integrity.
Support regulatory compliance with IEC 62443 standards.
Ensure operational continuity without production disruption.
Reduce safety risks from potential cyber incidents.
Build stakeholder confidence among regulators, partners, and customers.
