Operational Technology (OT) and Critical Infrastructure Security

Safeguarding the Backbone and Critical/Sensitive Systems of Your Organisation

As Operational Technology (OT) systems—like industrial machinery, energy grids, and transportation networks—become increasingly connected to corporate and broader networks, they face growing cyber risks. Once considered safe due to isolation, these systems are now vulnerable to attacks that can cause operational shutdowns, financial losses, and even threats to public safety.

At Shimazaki Sentinel, we understand the critical nature of these environments. Our specialised solutions protect your OT systems from evolving cyber threats, ensuring they remain secure, resilient, and capable of defending against potential harm.

Why Is OT and Critical Systems Cybersecurity So Important?

Unlike traditional IT systems, OT systems control physical processes like energy plants, manufacturing lines, and transportation networks. A breach in these systems goes beyond data loss—it can cause real-world damage, production stoppages, and put human safety at risk.

Our specialised OT and critical systems cybersecurity services provide robust protection for:

• Industrial Control Systems (ICS)
• Supervisory Control and Data Acquisition (SCADA) systems
• Energy grids and utilities
• Transportation and logistics networks
• Healthcare and critical infrastructure
• Defence and Defence/Industry operational systems
• Telecommunications and critical communication systems

At Shimazaki Sentinel, we ensure these essential systems are secure, resilient, and protected from evolving threats.

Our Operational Technology (OT) and Critical Infrastructure Security Services

At Shimazaki Sentinel, we provide a full range of services designed to protect your Operational Technology (OT) systems from ever-evolving cyber threats. Here’s how we ensure your critical infrastructure stays secure and efficient:

1. Risk Assessment and Vulnerability Management: We begin with a detailed evaluation of your OT systems to identify vulnerabilities that could put your critical infrastructure at risk. Our solutions are customised to address the unique challenges of OT environments, ensuring your operations stay safe.
2. OT Cybersecurity Strategy and Governance: We work alongside you to create a cybersecurity strategy that aligns with your operational goals while maintaining security. Our approach also covers the IT/OT boundary, where increased integration can create new vulnerabilities.
3. 24/7 Threat Detection and Response: Our around-the-clock monitoring services detect and respond to potential threats in real time, ensuring your OT systems are always protected. We proactively prevent cyberattacks before they disrupt your operations.
4. Incident Response and Recovery Planning: Being prepared is key in the event of a cyberattack. We help you develop and test Incident Response Plans (IRP) to ensure swift and safe recovery across both OT and IT systems, minimising downtime.
5. OT Security Training and Awareness: A knowledgeable workforce is the first line of defence. Our training programs equip your team to recognise and respond to OT-specific cyber threats.
6. IT/OT Boundary Convergence Security: As IT and OT systems become more interconnected, the boundary between the two can become vulnerable. We ensure this integration is secure, protecting your OT systems from risks that might come through the IT network.

With these services, Shimazaki Sentinel ensures your OT systems remain protected, efficient, and resilient in the face of cyber threats.
