Industrial control systems are the beating heart of critical infrastructure. SCADA systems, PLCs and HMIs are increasingly connected to IT networks, introducing new cyber threats. MVPeople Group delivers specialised OT/ICS security professionals who secure your operational technology without compromising availability.
Operational technology (OT) encompasses the hardware and software that monitors and controls physical processes: from power plants and water treatment facilities to production lines and transport systems. Securing these systems differs fundamentally from traditional IT security. Where IT prioritises data confidentiality, OT revolves around availability and safety.
Increasing IT/OT convergence makes industrial systems more vulnerable to cyber attacks. Previously isolated SCADA networks are being connected to corporate networks and the cloud for data analysis and remote monitoring. This significantly expands the attack surface. Incidents such as the attack on the Ukrainian power grid and the Colonial Pipeline hack demonstrate that the threat is real.
Securing OT environments requires a unique combination of knowledge: understanding of industrial protocols (Modbus, DNP3, OPC UA), experience with PLC programming and SCADA systems, and deep cybersecurity expertise. Frameworks such as IEC 62443, NIST SP 800-82 and NERC CIP provide guidelines, but implementation requires specialists who understand both the OT and security worlds.
MVPeople Group has a selective network of OT/ICS security professionals. From architects who implement the Purdue model to engineers who configure industrial firewalls and anomaly detection and consultants who guide IT/OT convergence projects. We deliver the expertise that keeps your industrial environment secure.
Designs the overarching security architecture for industrial environments. Defines network segmentation according to the Purdue model, zones and conduits per IEC 62443 and security reference architectures for OT networks.
Implements security controls in industrial control systems. Configures firewalls, intrusion detection for OT protocols, endpoint protection for HMIs and engineering workstations and secure remote access solutions.
Monitors OT networks for suspicious activities and anomalies. Analyses industrial protocols such as Modbus, DNP3 and OPC UA, and investigates security events in SCADA and DCS environments.
Deep expertise in securing SCADA systems and PLCs. Conducts vulnerability assessments on industrial controllers, configures secure communication protocols and implements access control for critical process control.
Guides organisations in the secure integration of IT and OT networks. Advises on architecture choices, data diodes, DMZ design and the secure exposure of operational data to IT systems and the cloud.
OT/ICS security focuses on securing industrial control systems such as SCADA, PLCs, DCS and HMIs. These systems control physical processes in sectors such as energy, water, manufacturing and transport. A successful cyber attack on OT systems can lead to physical damage, environmental disasters or outage of critical infrastructure. Due to increasing IT/OT convergence, these systems are increasingly exposed to cyber threats.
IT security focuses on protecting data (confidentiality, integrity, availability). In OT security, availability and safety come first: a production shutdown or unsafe situation has direct physical consequences. OT systems have longer lifecycles, often run on legacy software and cannot simply be patched without interrupting the production process. This requires a fundamentally different security approach.
The key frameworks are IEC 62443 (the international standard for industrial cybersecurity), NIST SP 800-82 (Guide to Industrial Control Systems Security) and NERC CIP (for the energy sector). Additionally, the NIS2 directive explicitly refers to securing essential services, which includes many OT environments. Our specialists have experience implementing all these frameworks.
OT security is a niche market with a limited number of specialists. We have a targeted network of professionals with backgrounds in both industrial automation and cybersecurity. We understand the unique combination of skills required: knowledge of PLC programming, industrial protocols and cybersecurity frameworks. This enables us to quickly make the right match.
IT/OT convergence is the integration of information technology (IT) and operational technology (OT) networks. Organisations want to expose operational data for analytics, predictive maintenance and optimisation. This brings security challenges: OT systems that were previously isolated are now connected to the IT network and potentially the internet. A solid segmentation strategy, data diodes and a clear zones-and-conduits model are essential.
The GICSP (Global Industrial Cyber Security Professional) is the most recognised OT security certification. Additionally, GRID (GIAC Response and Industrial Defense), IEC 62443 certifications and the ISA/IEC 62443 Cybersecurity Certificate are very valuable. Many OT security specialists combine these with a CISSP or CISM for the broader cybersecurity context.
Due to the niche nature of OT security, we use an indicative lead time of 5 to 15 working days for presenting suitable candidates. For generic OT security roles, availability is better than for highly specialised profiles such as SCADA security specialists with sector-specific experience. Contact us for a realistic estimate based on your specific requirements.
