Overview
Industrial Control Systems (ICS) and Operational Technology (OT) environments in the United States face increasing cyber threats. Critical sectors such as energy, manufacturing, transportation, and smart cities rely on secure ICS/OT systems. Cyber incidents can lead to operational downtime, safety hazards, financial loss, 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 cybersecurity management. Compliance demonstrates strong security posture and regulatory adherence.
Cyberintelsys, a CREST-accredited cybersecurity company, delivers comprehensive Vulnerability Assessment (VA) and Penetration Testing (PT) services aligned with IEC 62443 in the United States. Our services help industrial 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 high-availability systems. 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 disrupting production.
Reduce safety risks from potential cyber incidents.
Build stakeholder confidence among regulators, partners, and customers.
Cyberintelsys CREST-Accredited VA/PT Approach
Our methodology combines technical rigor, regulatory alignment, and hands-on ICS/OT expertise.
1. Scoping & Asset Mapping
Identify ICS/OT assets including PLCs, HMIs, SCADA servers, RTUs, sensors, and industrial networks.
Map communication flows between OT layers, IT systems, remote access, and cloud interfaces.
Define safe testing boundaries to maintain operational continuity.
2. Vulnerability Assessment (VA)
ICS-specific automated scanning and threat intelligence analysis.
Configuration and access control review.
Industrial protocol assessment including Modbus, DNP3, OPC, IEC 60870.
Firmware and software review to detect unpatched systems or insecure components.
3. Penetration Testing (PT)
Network penetration testing between IT and OT environments.
Controlled device exploitation on PLCs, HMIs, SCADA servers, and RTUs.
Remote access and wireless network testing.
Process impact simulation in controlled environments.
4. Risk Analysis & Prioritization
Assess likelihood, operational impact, and safety implications for each vulnerability.
Prioritize remediation in line with IEC 62443 guidelines.
5. Reporting & Compliance Documentation
CREST-aligned, audit-ready reports.
Actionable guidance for mitigation and IEC 62443 compliance.
Roadmap for continuous improvement in ICS/OT cybersecurity.
6. Retesting & Validation
Post-remediation validation ensures vulnerabilities are mitigated.
Confirms ongoing IEC 62443 compliance.
