NGT chose to collaborate with us to produce a proof of concept for implementation and rollout across the Gas Quality OT Fleet.

• WaterFall Security Data Diode – Proof of Concept
• nZero Proof of Concept (PoC) for implementation of unidirectional gateway for NGT CNI
• Delivered under RIIO2 Gas Quality & Metering Framework
• Location: Nationally – UK

nZero’s Value Add + Select Equipment & Advantages

• Enabling access to OT data, eliminating vulnerability and enabling industrial connectivity without adding Cyber Risk
• Bespoke cyber security solution, developed under this project PoC purchase order, for NGT CNI sites, roll out planned for 2025 following successful testing.
• Test Suite created to verify data transfer, via data diode waterfall gateway.
• Light source used to transmit data across two diodes, transmitter and receiver, physically separating assets from vulnerable networks.
• Replicates on-site data across two industrial PC’s enabling operators to safety access OT data remotely.
• Unidirectional gateway provides unbreachable protection within OT environment.

Key elements
