OT Security posture improvemnet and Digital Transformation

This project aims to establish a robust, scalable OT cybersecurity infrastructure that supports the digital transformation of our organization’s global terminals in a secure, cohesive framework. The end goal is to elevate OT cybersecurity maturity across all terminals under Horizon terminals LTD by deploying hyperconverged security infrastructure and integrating these systems within a centralized command center.

Followed by a rigorous assurance testing of this security infrastructure the Phase 2 will integrate this new infrastructure with the existing ICS/OT environment and MES, IT Environment and facilitate the central security and integration command center respectively. The phase 2 scope also included upgrades / replacements for the Legacy OT systems.

This central hub will deliver streamlined security and integration services, enabling continuous oversight and response across geographically dispersed locations. Through secure, centralized integration with our Manufacturing Execution Systems (MES) and IT environments, the project enhances data accessibility, collaboration, and real-time threat mitigation.

In creating this integrated cybersecurity foundation, we ensure resilient, compliant operations while advancing our digital transformation objectives. The initiative not only addresses the security needs of today’s digital landscape but also paves the way for future advancements in process optimization, operational efficiency, and innovation across our enterprise.

Implementing the OT Security Posture Improvement and Digital Transformation project presented significant challenges, given its scale across nine terminals in four international locations (UAE, KSA, Singapore, Morocco, and Djibouti). The project required meticulous coordination to manage diverse operational and regulatory landscapes, balancing the integration of cutting-edge OT security infrastructure with the unique demands of each terminal.

One of the primary challenges involved downtime planning for OT production systems. With critical operations running on legacy OT systems, extensive scheduling was essential to minimize disruptions. Coordinating with operational teams across terminals required careful timing and alignment to ensure continuity in essential services. Legacy OT systems further added to the complexity, as these systems demanded strategic upgrades to support new security frameworks while managing scope creep in evolving project requirements.

The sheer scale of infrastructure deployment added another layer of difficulty. We successfully implemented around 400 virtualized servers alongside an equivalent volume of networking infrastructure, an achievement that required robust resource allocation and coordination. Additionally, inter-disciplinary resource management proved complex, with teams from OT, IT, engineering, and cybersecurity needing to work in concert to bring specialized expertise to the deployment and integration processes.

Despite these challenges, the project delivered a resilient and scalable OT cybersecurity framework that now supports a secure digital transformation across our global terminals.

This project was designed to redefine OT cybersecurity across Horizon Terminals Ltd., creating a comprehensive, centralized framework that protects critical infrastructure and supports secure digital transformation. By deploying hyperconverged security infrastructure across all global terminals and integrating these systems with a centralized security command center, the project achieved a robust, scalable defense structure for our OT environments.

In its initial phase, the project focused on establishing a strong OT cybersecurity foundation with rigorous assurance testing. This approach enabled early risk mitigation for industrial control systems, significantly reducing exposure to potential cyber threats while ensuring operational continuity. The subsequent phase extended this framework through secure integration with existing ICS, MES, and IT systems, bringing together legacy OT systems with advanced security protocols that align with industry standards. This ensured the project's compliance with regulatory requirements, minimized legal risks, and protected our market reputation.

Notable outcomes include enhanced incident response efficiency, reducing the mean time to detect and respond to threats, and real-time threat detection powered by advanced anomaly detection algorithms. This responsiveness allowed us to contain potential breaches swiftly, minimizing operational disruptions and reinforcing our defenses. Additionally, continuous cybersecurity awareness programs empowered employees across all levels to recognize and combat potential threats, building a culture of vigilance against social engineering and insider risks.

With secure OT-IT integration, our terminals now benefit from enhanced interoperability through access controls, network segmentation, and secure communication protocols—creating a seamless and resilient operational environment. This project has not only established a scalable, secure OT infrastructure but also positioned us for sustained digital innovation and optimization across our global enterprise, driving future advancements in both process efficiency and cybersecurity resilience.

The OT Security Posture Improvement and Digital Transformation project spanned nine terminals across four countries, covering key locations in the UAE, Saudi Arabia, Singapore, Morocco, and Djibouti. This extensive geographical reach required a cohesive approach to standardize cybersecurity measures across diverse operational and regulatory environments.

Each terminal’s security infrastructure was upgraded to align with an overarching centralized command structure, providing unified oversight and streamlined security services. The multi-country implementation involved deploying hyperconverged infrastructure to support advanced OT cybersecurity and integration needs, enabling seamless connectivity with our Manufacturing Execution Systems (MES) and IT networks. By coordinating efforts across these strategic locations, we successfully reinforced our global security posture, ensuring resilience and consistency across all terminals.
