Unauthorised setpoint changes carry safety and supply consequences. 02 ### Distributed AGI estate Above ground installations and PRS sit across the network and depend on remote telemetry to be operated safely. 03 ### Shipper and market interfaces Shipper nominations and market interfaces sit close to the operational estate, creating paths that attackers can traverse. Utilities - Gas > When SCADA, AGI control and safety systems share the same network, every software vulnerability becomes a candidate for a pressure or supply incident. The Scenario ### Scenario: AGI controller firmware compromise Attackers compromise a vendor firmware distribution server and push a malicious update into an AGI controller during a routine maintenance window. The update propagates through a shared engineering network to several neighbouring sites before it is detected. Operators lose confidence in the integrity of pressure readings for hours. With Control, vendor firmware crosses into operations only through a brokered path with origin and integrity checks. Updates that reach an AGI controller require named, multi-party approval per site. The safety integrity system sits on its own fabric and cannot be reached from the control network at all. Verified baselines for AGI configuration are held on infrastructure that has no live network path to production and require multi-party authorisation to release. "If the safety system and the control system share a network, you do not have a safety system. You have a wish." Module deployment · gas transmission and distribution network ## Where each Control module is deployed across compressors, AGIs and the distribution grid. Gas operators run a high-consequence SCADA estate across compressor stations, above ground installations and pressure reduction stations. Control puts a real boundary between the office, the SCADA control room, the AGI telemetry and the safety systems that keep pressure in band. Grounded in NIST SP 800-82 Rev. 3, IEC 62443-3-2, HSE COMAH guidance and Ofgem security expectations.

### Sovereign gas data Operational and shipper data remains within the agreed jurisdiction in carefully selected Firevault Bunkers. 02 ### Multi-party control Pressure and major valve operations require sign-off from both control room and security teams. 03 ### Regulatory evidence Continuous compliance evidence aligned to NIS2, HSE COMAH and Ofgem cyber expectations. 04 ### Out-of-band management Cellular and dedicated paths keep the control plane reachable when primary networks are compromised. 05 ### Tamper-proof logging Every access, configuration change and pressure action lands in immutable logs on physically separate infrastructure. 06 ### Verified configuration baselines Verified baselines of AGI, PRS and compressor configuration enable a known-good restore of control-plane state. Demo to Live ## Adoption Guide Step 1 #### Network assessment Map every path between corporate IT, SCADA, AGI control and the safety integrity systems to identify convergence and persistent vendor connections. Step 2 #### Zone architecture design Design physically separated zones aligned to your transmission and distribution estate, with Control modules at each boundary. Step 3 #### Non-production pilot Deploy in a test environment mirroring an AGI and SIS pair with full zone separation, multi-party authorisation and compliance logging. Step 4 #### Operational deployment Full deployment across the gas estate with verified configuration baselines, continuous compliance evidence and 24/7 out-of-band management.
