Overview
Industrial Control Systems (ICS) and Operational Technology (OT) environments in Canada face increasing cybersecurity threats. Key sectors such as manufacturing, energy, water, transportation, and smart infrastructure rely heavily on secure ICS/OT systems. Cyber incidents can cause operational downtime, safety risks, financial losses, and regulatory non-compliance.
IEC 62443 is a globally recognized cybersecurity standard tailored for ICS/OT environments. It provides a structured framework for risk assessment, system security requirements, secure development lifecycle, and continuous cybersecurity management. Adhering to IEC 62443 supports Canadian regulatory compliance, strengthens critical infrastructure protection, and demonstrates cybersecurity diligence.
Cyberintelsys, a CREST-accredited cybersecurity company, offers comprehensive IEC 62443-aligned Vulnerability Assessment (VA) and Penetration Testing (PT) services across Canada. Our services help organizations identify, assess, and remediate cybersecurity risks while maintaining operational safety and continuity.
Importance of VA/PT for IEC 62443
ICS/OT systems differ from traditional IT networks, often comprising legacy devices, proprietary protocols, and safety-critical processes that cannot tolerate downtime. Vulnerabilities may exist in PLCs, HMIs, SCADA servers, industrial networks, remote access systems, and IT-OT integration points.
Detect critical vulnerabilities impacting safety, availability, or process integrity.
Support regulatory compliance with IEC 62443.
Maintain operational continuity without disrupting production.
Mitigate safety risks from potential cyber incidents.
Build confidence among regulators, partners, and clients.
Partnering with a CREST-accredited provider like Cyberintelsys ensures ethical, standardized, and globally recognized testing practices.
Cyberintelsys CREST-Accredited VA/PT Approach
