Overview
Industrial Control Systems (ICS) and Operational Technology (OT) environments across Belgium are becoming increasingly interconnected as organizations adopt Industry 4.0 technologies, smart manufacturing, and digital automation. While this transformation improves efficiency and productivity it also expands the attack surface for cyber threats. Critical industries such as manufacturing, energy, chemicals, pharmaceuticals, utilities and transportation rely heavily on ICS and OT systems to maintain safe and continuous operations. A successful cyberattack on these environments can result in production downtime, financial losses, safety incidents and regulatory violations.
IEC 62443 is a globally recognized cybersecurity standard designed specifically to address the unique security challenges of industrial automation and control systems. In Belgium where industries must comply with European regulations and international security expectations aligning with IEC 62443 is essential for operational resilience and regulatory readiness.
Cyberintelsys, a CREST certified cybersecurity company, supports organizations in Belgium with comprehensive IEC 62443 cybersecurity assessments and compliance readiness services. Our approach helps organizations identify security gaps, assess cyber risks and implement practical controls that protect ICS and OT environments without disrupting operations.
Importance of Cybersecurity Assessment for IEC 62443 Compliance
ICS and OT environments differ significantly from traditional IT systems. They often include legacy equipment, proprietary industrial protocols and systems that must remain available at all times. Security controls must be carefully designed to avoid impacting safety or production processes. Common vulnerabilities may exist in PLCs, HMIs, SCADA servers, industrial networks, remote access solutions and system configurations.
Cybersecurity assessments play a critical role in IEC 62443 compliance because they help organizations understand their current security posture and define a clear path toward compliance. Key benefits include identifying vulnerabilities that could impact safety or availability, aligning security controls with IEC 62443 requirements, reducing cyber risk without interrupting production and improving confidence among regulators customers and partners.
Working with a CREST certified provider like Cyberintelsys ensures that assessments follow internationally accepted methodologies and ethical testing standards tailored for ICS and OT environments.
Cyberintelsys IEC 62443 Cybersecurity Assessment Approach
Cyberintelsys follows a structured and risk-based approach aligned with IEC 62443 standards and industrial best practices. Our methodology focuses on visibility, accuracy and actionable outcomes.
1. Scoping and Asset Identification
The assessment begins with defining the scope and identifying all relevant ICS and OT assets. This includes PLCs, HMIs, SCADA systems, distributed control systems, RTUs, industrial servers, sensors and network components. Communication flows between OT layers, IT systems and external connections are documented. Clear scoping ensures assessments are safe and aligned with operational constraints.
2. Cybersecurity Gap Analysis
Cyberintelsys performs a detailed gap analysis against IEC 62443 requirements across relevant sections such as IEC 62443-2-x for policies and procedures, IEC 62443-3-x for system security and IEC 62443-4-x for component security. Existing controls are evaluated against standard requirements to identify gaps in governance, access control, network segmentation, system hardening and monitoring.
3. Risk Assessment and Threat Modeling
Each identified gap is evaluated through a structured risk assessment. Threat modeling is performed to understand potential attack paths and real-world impact using industrial threat frameworks such as MITRE ATT&CK for ICS. Risks are prioritized based on likelihood, impact, safety implications and operational criticality.
4. Configuration and Architecture Review
Cyberintelsys reviews network architecture, security zones and conduits, firewall configurations, authentication mechanisms and remote access controls. This helps validate whether segmentation and access restrictions align with IEC 62443 design principles and reduce the risk of lateral movement between zones.
5. Compliance Readiness and Roadmap Development
The assessment concludes with a clear compliance readiness evaluation. Cyberintelsys provides a practical remediation roadmap outlining prioritized actions technical controls and process improvements needed to achieve or maintain IEC 62443 compliance. Recommendations are designed to be achievable within operational and budgetary constraints.
