Delivering operational technology solutions in support of critical national infrastructure

Vysiion delivers operational technology solutions that support projects across critical national infrastructure, including utilities, renewables, and transport, built on a foundation of world-class connectivity.

Integration of your disparate systems

Securely and effectively integrating multiple sites and disparate systems demands optimal network connectivity and a robust cyber security ecosystem. Vysiion combines a high-performance network with an in-house, 24/7 NOC capability, and more than twenty years’ experience in delivery of critical infrastructure.

Regulatory compliance assurance

Critical national infrastructure projects must meet the most stringent compliance requirements, particularly around NIS guidelines for cyber security and on-site health & safety. Vysiion’s operational technology solutions have been created with the highest standard of compliance inherent in the design.

Strategic migration of legacy systems

The drive for smart solutions generating high volumes of complex data frequently reveals the limitations of legacy systems. Vysiion offers consultancy and project management that facilitates the migration of legacy operational technology to integrate with smart next generation solutions.  This ensures zero disruption and no compromise in terms of cyber security, providing a strong foundation for future growth.

Our Services

All operational technology projects Vysiion undertakes begins with a period of in-depth consultation, to determine the current state of the infrastructure, the short- and long-term objectives. An iterative design process then begins, including the delivery of detailed design packs, ensuring targets are met, quality is maintained, and the deployment is completed on time. 

Solutions are built in-house and subject to an intensive pre-staging phase before shipment to site, installation and commissioning. Following a formal handover process, you have the option to take 24/7 proactive monitoring to ensure potential security threats are identified and resolved, and patches are applied as needed.

Our approach

With an extensive track record of successfully delivering the most challenging projects, in the most challenging environments, combined with world-class network connectivity, we design, deliver, and manage critical infrastructure solutions that supports the ongoing growth of IoT and smart solutions 

Drawing on this experience, we take a consultative, vendor-agnostic approach that recognises the unique challenges faced by the CNI and utilities sectors, while our highly experienced design engineers enjoy the support of a comprehensive network of specialists in operational technology, networking, and cyber security. Our solutions are built and tested at our own purpose-built facilities, in order to guarantee optimal quality, agile and efficient deployments.
