OT cybersecurity support for gas transmission, energy infrastructure, compressor control, telemetry, vendor access, safety interfaces and assurance requirements.
Gas and energy infrastructure depends on reliable control systems, resilient communications and clear operational ownership. Compressor stations, AGIs, terminals, telemetry systems, substations, metering packages and remote assets often rely on long-life control equipment that was not originally designed for current cybersecurity expectations.
The challenge is rarely just cybersecurity. It is keeping essential services running while improving visibility, reducing exposure and producing evidence that satisfies engineering, operations, compliance and assurance stakeholders.
Examples on this page are fictionalised, generalised or anonymised to show typical problem types without identifying real clients, real sites, real drawings, real systems or confidential project details.
Many gas and energy sites have grown over time. New systems are added, vendors connect equipment, telemetry links are extended and temporary arrangements become permanent.
Over several years, the result can be a control system environment that works operationally but is difficult to explain, evidence or defend. Pressure is usually highest when a project, audit, client review or regulatory requirement exposes gaps that have existed for years.
Gas and energy cybersecurity decisions affect more than the IT or cyber team. Meridian helps bring these groups into one practical engineering view.
Meridian Consultants supports OT cybersecurity improvement in gas and energy environments by helping teams understand what they have, where the real exposure is and what needs to change first.
The aim is not to produce generic cybersecurity paperwork. The aim is to produce engineering-led evidence that helps operations, projects and assurance teams make defensible decisions.
A useful OT cybersecurity review should leave engineering, operations and assurance teams with a clearer basis for action.
A UK energy infrastructure operator required a review of OT network arrangements at a remote operational facility. The environment included PLC-based control, SCADA workstations, telemetry links, vendor access routes and legacy communications.
The objective was to understand the existing architecture, identify practical segmentation options, clarify support routes and produce evidence suitable for design review and assurance close-out.
The following external references provide useful context for organisations considering OT cybersecurity, assurance, NIS alignment or IEC 62443-based control system security work.
