This case study explains how a major petrochemical producer strengthened operational technology cybersecurity by implementing a multi-layered, secure-by-design network and cloud architecture across its manufacturing plants. The project focused on improving system integrity, availability, and compliance with IEC-62443 cybersecurity standards for industrial control systems. The solution included segmented OT networks, firewalls, centralized monitoring, cloud migration, patch management, and controlled access layers separating enterprise IT and plant operations. The result was improved operational visibility, reduced cyber risk, stronger compliance, and a more secure foundation for future expansion and data-driven operations.
