Industrial organizations across the Netherlands are undergoing rapid digital transformation as they integrate smart automation, IIoT devices, expanded remote access and cloud-connected ICS and OT systems. While this level of modernization enhances efficiency and operational intelligence it also increases exposure to cyber threats that target critical infrastructure. Industries such as manufacturing, water management, oil and gas, logistics, maritime operations, renewable energy and advanced technology R&D rely heavily on secure industrial control environments to maintain reliability and safety.

With rising cyberattacks affecting OT networks globally, complying with internationally recognized standards has become essential. The IEC 62443 framework is the leading global benchmark for industrial cybersecurity. It provides a structured approach to assessing risks, protecting systems and ensuring operational resilience across the entire lifecycle of ICS and OT environments. For Dutch industrial organizations aiming to strengthen their cybersecurity posture while meeting regulatory expectations, IEC 62443 compliance is no longer optional but a critical requirement.

Cyberintelsys, a CREST certified cybersecurity company, supports organizations across the Netherlands with comprehensive IEC 62443 cybersecurity assessments and compliance readiness services. Our experts help industries understand their current security posture, identify system weaknesses, evaluate maturity against IEC 62443 requirements and implement controls that enhance operational resilience and reduce risk.

Overview of ICS and OT cybersecurity challenges in Netherlands

The Netherlands is a global leader in industrial innovation and automation. Sectors such as maritime operations, high-tech manufacturing, transport logistics, chemical production and renewable energy rely on interconnected operational systems that must remain available 24/7. However, this interconnectedness introduces cybersecurity risks that must be addressed proactively.

OT networks differ significantly from traditional IT systems. They contain legacy devices, outdated operating systems, proprietary protocols and hardware designed primarily for reliability rather than security. Unlike IT networks where downtime can be tolerated, ICS systems must remain continuously available to ensure physical processes function as expected. Even minor disruptions can result in production downtime, safety hazards or regulatory violations.

Cyber threats targeting European industrial environments continue to increase in volume and sophistication. Ransomware campaigns, advanced persistent threats, supply chain infiltration, remote-access attacks and disruptions to SCADA systems pose significant risks. Dutch industries must treat OT security as a top priority, making IEC 62443 compliance a strong foundation for mitigating these threats.

Importance of IEC 62443 cybersecurity assessment and compliance readiness

An IEC 62443 cybersecurity assessment helps organizations evaluate how well their ICS and OT environments meet the security requirements outlined in the standard. This includes technical controls, administrative policies, physical safeguards and operational practices that reduce risk and ensure resilient industrial operations.

Key reasons why Dutch industries require IEC 62443 assessments include:

1. Enhancing ICS and OT system security

Assessments identify vulnerabilities in devices, communication protocols, access controls and network architecture. This helps prevent unauthorized access or manipulation of critical industrial processes.

2. Aligning with global and regional regulations

European industries are increasingly required to adopt structured cybersecurity frameworks. IEC 62443 compliance supports alignment with EU NIS2 requirements, government cybersecurity guidelines and sector-specific regulations.

3. Minimizing operational disruptions

By proactively identifying weaknesses, organizations reduce the likelihood of downtime caused by cyberattacks. This ensures stable production quality and process integrity.

4. Strengthening stakeholder confidence

Clients, regulators, technology partners and investors increasingly expect industrial facilities to demonstrate strong cybersecurity maturity. IEC 62443 compliance enhances trust and credibility.

5. Supporting long-term cybersecurity maturity

Readiness assessments help organizations build a roadmap for continuous improvement instead of one-time fixes or reactive measures.

Cyberintelsys provides end-to-end evaluation, testing, documentation and improvement strategies tailored to the unique needs of Netherlands-based industrial environments.

Cyberintelsys IEC 62443 assessment and compliance readiness approach

Cyberintelsys takes a comprehensive and structured approach using CREST certified methodologies combined with IEC 62443 guidance. Our process ensures organizations understand risks clearly and implement appropriate controls for secure and resilient OT operations.

1. Asset discovery and system mapping

We identify all ICS components such as PLCs, sensors, RTUs, HMIs, SCADA servers, networking devices, remote access gateways and cloud integrations. Mapping communication flows and trust zones provides a complete view of the industrial environment.

2. Gap analysis against IEC 62443 requirements

Our experts evaluate security controls across IEC 62443 parts including:
• IEC 62443-2-1 (security program requirements)
• IEC 62443-3-3 (system security requirements and levels)
• IEC 62443-4-1 and 4-2 (secure development and component requirements)

We highlight strengths, deficiencies and areas requiring improvement.

3. Vulnerability assessment of ICS and OT assets

We assess device vulnerabilities, misconfigurations, outdated software, insecure protocols, weak authentication methods and network segmentation issues. We use ICS-specific tools that do not disrupt operations.

4. Risk evaluation and prioritization

Each finding is evaluated based on:
• likelihood of exploitation
• impact on safety, operations and regulatory compliance
• potential business consequences

This ensures organizations focus on the risks that matter most.

5. Maturity scoring and compliance benchmarking

We score your current security posture based on IEC 62443 maturity levels from basic controls to advanced protections. This creates a measurable baseline for improvement.

6. Development of a compliance readiness roadmap

Cyberintelsys provides a step-by-step roadmap that helps your organization improve policies, implement controls and strengthen OT security to achieve compliance.

7. Advisory support and implementation assistance

We assist in strengthening controls such as:
• network segmentation
• firewall rule optimization
• user access management
• secure remote access
• patch management strategies
• continuous monitoring and anomaly detection
• incident response for industrial environments

8. Validation and retesting

After implementing improvements we retest to ensure controls are effective and meet IEC 62443 requirements.
