Overview
Industrial Control Systems (ICS) and Operational Technology (OT) environments in the United States face increasing threats from advanced cyberattacks. Critical sectors such as manufacturing, energy, water, transportation, and smart infrastructure rely heavily on secure ICS/OT systems. Cyber incidents can result in operational downtime, safety hazards, financial loss, and regulatory penalties.
IEC 62443 is a globally recognized cybersecurity standard for ICS/OT environments, providing a framework for risk assessment, system security requirements, secure development lifecycle, and continuous cybersecurity management. Compliance with IEC 62443 ensures protection of critical infrastructure and demonstrates cybersecurity diligence.
Cyberintelsys, a CREST-accredited cybersecurity company, offers comprehensive IEC 62443-aligned Vulnerability Assessment (VA) and Penetration Testing (PT) services in the United States. Our services help organizations identify, assess, and mitigate cybersecurity risks while maintaining operational safety.
Importance of VA/PT for IEC 62443
ICS/OT systems differ significantly from traditional IT networks. They include legacy devices, proprietary protocols, and high-availability processes that cannot tolerate downtime. Vulnerabilities may exist in PLCs, HMIs, SCADA servers, industrial networks, remote access points, and IT-OT integrations.
Identify critical vulnerabilities impacting safety, availability, or process integrity.
Support regulatory compliance with IEC 62443 standards.
Protect operational continuity without disrupting production.
Reduce safety risks from potential cyber incidents.
Build confidence among regulators, partners, and customers.
Engaging a CREST-accredited provider like Cyberintelsys ensures ethical and globally recognized testing practices.
