Our Services

With expert knowledge and industry-leading expertise in the IT, OT and CNI sectors, Vysiion’s technology experts, consultants, and project managers will delve deep into your specific cyber security requirements, designing, delivering, and managing a bespoke, end-to-end solution. Throughout every stage of this process, we work closely with your own teams to ensure targets are met and a successful, on-time launch can be achieved with minimal disruption to your day-to-day operations.

Drawing on the capabilities and expertise of our partner network, we can provide a variety of solutions to help you meet the key points of the NIS Directive, often starting out with network discovery. We can also provide you a passive Intrusion Detection System that monitors every packet sent across your network, allowing you to maintain the highest standard of cyber security across every location in which you operate, without compromising performance or availability.

Our approach

Vysiion’s consultative approach, vendor-agnostic technology portfolio, and deep knowledge of CNI and utilities allows us to deliver truly bespoke cyber security solutions that meet the public sector’s most stringent requirements regarding the transferring, management, and storage of sensitive data.

Furthermore, we understand that the availability of your network and high-level visibility of your infrastructure across all sites is of paramount importance, and so we design your operational technology cyber security with this in mind, providing you with full visibility and control, while our own cyber security team provides comprehensive reporting and proactive monitoring.

Why Vysiion?

Vysiion has worked within the CNI and utilities sectors since 1996, and is a leader in the convergence of IT and OT. We’ve supplied and worked on a wide range of systems and networks in that time. We use this knowledge and experience in both our technology and delivery approach to help you protect your critical assets.
