Industrial Cybersecurity
Industrial Cybersecurity by BEIMCO
As industrial automation and control systems (IACS) increasingly integrate with IT and IIoT technologies, cybersecurity has become a critical component in safeguarding operational technology (OT). Our IACS cybersecurity services are designed to protect critical infrastructure, manufacturing plants, and industrial facilities against evolving cyber threats. We offer a comprehensive portfolio tailored to IEC 62443 and NIST 800-82 frameworks, ensuring confidentiality, integrity, and availability of your control systems. From risk assessment and architecture design to compliance and incident response, we partner with clients to strengthen their cyber defence posture across all levels of industrial operations.

BEIMCO’s Defense for Industrial Cybersecurity
Cybersecurity Risk Assessment & Gap Analysis
Our cybersecurity risk assessment and gap analysis service is the foundation of a robust IACS defence strategy. We perform a thorough evaluation of your current systems, policies, and procedures to identify vulnerabilities that could compromise system availability, safety, and reliability. Using a combination of asset inventory, threat modelling, and risk evaluation techniques, we map your existing environment against recognized standards such as IEC 62443, ISO 27001, and NIS2. The analysis includes identifying unauthorized access points, unpatched software, insecure communication protocols, and insufficient user access controls. Our deliverables include a detailed report with a prioritized list of vulnerabilities, risk ratings, and recommended mitigation strategies. This helps your team understand where you stand today and provides a clear roadmap to elevate your cybersecurity maturity. Whether you are operating a greenfield or brownfield site, this assessment will help ensure your systems are ready to face the modern threat landscape while maintaining regulatory compliance and operational excellence.
Security Architecture Design
A secure architecture is essential for any IACS environment to prevent unauthorized access, malware propagation, and internal threats. Our security architecture design service builds layered protection using defence-in-depth principles tailored for industrial automation networks. We begin by understanding your process requirements and network topology, then design secure zones and conduits in line with IEC 62443-3-2 recommendations. Our solution includes segmentation of enterprise and control networks, secure remote access using VPNs, deployment of firewalls and DMZs, and access control lists for field devices. We also address endpoint protection, secure firmware updates, secure boot processes, and logging mechanisms. The architecture is scalable and flexible, enabling seamless integration with future expansion plans, IIoT systems, or cloud services. We deliver detailed documentation including network diagrams, architecture specifications, and implementation guidelines. Our goal is to design a resilient infrastructure that ensures operational continuity while minimizing cyber risks in industrial environments.
IEC 62443 Compliance Support
Compliance with IEC 62443 is a strategic investment in your plant’s cybersecurity and operational reliability. Our IEC 62443 compliance service guides you through the full lifecycle of implementing cybersecurity controls that align with industry best practices. We start by identifying which parts of the IEC 62443 standard apply to your organization—whether it’s for asset owners, integrators, or product suppliers. We help create Security Plans (SL-T), perform Security Level assignments, and develop Risk Assessments and Threat Modelling according to SL-C and SL-A. Our services include the development of cybersecurity policies, procedures, and technical controls necessary to meet specific security levels (SL1 to SL4). We also assist with vendor selection and system integration to ensure procured systems are compliant. Whether you aim for certification or internal validation, we offer training, documentation, and audit preparation to support your compliance journey. By adopting IEC 62443, you not only improve your cybersecurity readiness but also demonstrate commitment to international standards, enhancing trust among partners, clients, and regulators.
Security Hardening & Patch Management
Security hardening reduces the attack surface of your IACS environment by removing unnecessary services, enforcing strong access controls, and applying security best practices at the device and system level. Our service begins with a system-wide audit of all devices, including PLCs, RTUs, HMIs, and servers. We analyse configurations, user roles, network permissions, and software installations. Based on findings, we implement secure configurations—disabling unused ports, enforcing password policies, and applying secure communication protocols like HTTPS, SFTP, and OPC UA with encryption. We also implement patch management frameworks designed for OT environments, where uptime is critical. This includes evaluating patch risk, testing in simulated environments, and deploying updates during planned maintenance windows. For legacy systems, we provide compensating controls to minimize exposure. Detailed documentation is provided for all changes, helping you maintain a hardened baseline that aligns with IEC 62443 and NIST SP 800-82. With our approach, your control systems remain secure, compliant, and optimized for operational reliability.
Incident Response Planning & Recovery
Even with the best defences, cyber incidents can occur. Our incident response planning and recovery service ensures your team is prepared to respond swiftly and effectively, minimizing disruption and damage. We begin by assessing your existing incident response capabilities and identifying gaps in people, processes, and tools. Then we help develop customized response plans tailored to your IACS environment, covering threat detection, containment, eradication, and recovery. These plans are aligned with NIST SP 800-61 and IEC 62443-4-1. We conduct tabletop exercises and simulations to train staff and validate procedures. We also help implement forensic logging and monitoring solutions to ensure visibility into system activity before, during, and after an event. Post-incident, we provide analysis to understand root causes and implement corrective measures. This comprehensive approach helps you build organizational resilience, reduce downtime, and meet regulatory requirements. With a strong incident response plan, your operations are protected, and your team is empowered to act decisively when it matters most.
