Overview
Operational Technology (OT) and Industrial Control Systems (ICS) in the United States are increasingly exposed to cyber threats targeting critical infrastructure. Industries such as energy, manufacturing, transportation, and smart city systems require robust cybersecurity to prevent operational disruptions, safety hazards, and regulatory non-compliance.
IEC 62443 provides a globally recognized framework for OT cybersecurity, offering structured guidelines for risk evaluation, system security requirements, secure lifecycle management, and continuous monitoring. Compliance ensures protection of critical infrastructure and demonstrates proactive cybersecurity diligence.
Cyberintelsys, a CREST-accredited cybersecurity company, delivers comprehensive IEC 62443-aligned Cybersecurity Readiness and Risk Evaluation services across the United States. Our services help organizations assess OT security, identify vulnerabilities, and maintain operational safety and compliance.
Importance of OT Cybersecurity Readiness
ICS/OT environments differ from traditional IT systems, often containing legacy equipment, proprietary protocols, and critical processes that cannot tolerate downtime. Cyber vulnerabilities in PLCs, HMIs, SCADA servers, industrial networks, and remote access points can have severe operational and safety impacts.
Identify and evaluate critical vulnerabilities affecting safety, operational continuity, and compliance.
Demonstrate alignment with IEC 62443 standards.
Maintain uninterrupted operations during assessment and remediation.
Mitigate safety risks associated with potential cyber incidents.
Build confidence among regulators, partners, and stakeholders.
