OT cyber resilience across power generation, transmission and distribution, and the gas networks that keep the lights on.

When the grid goes down, everything goes dark.

Energy and utilities are the infrastructure every other sector depends on. A cyber incident in OT does not stay digital, it becomes lost generation, an unstable grid, or interrupted supply.

The estate is vast and long-lived: generation plant, substations, transmission and distribution SCADA, and gas networks, much of it engineered decades before these systems were ever connected.

Connectivity, remote operation and distributed renewable generation have widened the attack surface faster than the controls, and the safety regime around them, have kept pace.

230k+

Ukraine grid, 2015

A coordinated cyberattack switched off substations and cut power to around 230,000 people, the first confirmed grid takedown by cyber means.

6days

Colonial Pipeline, 2021

A ransomware attack shut the largest US fuel pipeline for six days and triggered regional shortages, with OT precautionarily isolated.

Across the energy value chain

Our work maps directly onto the problems energy operators face, across generation, the grid, and gas networks.

Power generation, Energy & Utilities
01Energy & Utilities

Power generation

Thermal, nuclear, hydro and renewable generation, and the DCS, SCADA and safety systems that run it.

The problem

Generation runs on long-lived control systems, DCS, SCADA, PLCs and safety instrumented systems, that were built for availability and safety, not adversaries. Many plants now reach back to corporate IT and out to OEM remote support, and renewable and distributed assets add large fleets of connected, remotely managed equipment. A cyber incident can force an unplanned trip, threaten the safety case, or take generation offline at the worst possible moment for the system.

  • OT Programme Design & Delivery
  • Site Enablement
  • Readiness for major incidents
  • OT Security Due Diligence
  • OT Supply-Chain GRC

How we solve it

  • Build asset visibility and a defensible network architecture across DCS, SCADA and plant systems, without disrupting generation.
  • Separate safety instrumented systems from the wider control network and verify the segregation under a single assurance view.
  • Bring OEM and third-party remote access under control, with continuous supply-chain assurance.
  • Put incident readiness in place that assumes a trip or service-down scenario, with rehearsed, safe recovery.
  • Assure cyber posture at the point of new build and renewable capex, before risk is engineered in.

Generation availability protected, with the safety case preserved as plant becomes more connected.

Controlled, monitored remote access for OEMs and operators.

Faster, rehearsed recovery when an incident forces a trip.

Cyber risk priced into new-build and renewable investment, not discovered after go-live.

Transmission & distribution, Energy & Utilities
02Energy & Utilities

Transmission & distribution

Substations, grid SCADA, protection and control, and the operational networks that balance the system.

The problem

The grid depends on geographically dispersed substations, protection and control, and grid SCADA that must operate in real time to keep the system stable. Digital substations and wide-area connectivity have widened exposure, and the Ukraine attacks proved that manipulating this layer can switch off power directly. The estate is hard to monitor and physically secure, and operators depend on a small number of vendors and integrators.

  • OT Programme Design & Delivery
  • Penetration testing
  • OT Supply-Chain GRC
  • Readiness for major incidents
  • Continuous resilience monitoring

How we solve it

  • Build visibility across substation automation, protection and grid SCADA, and segment it from corporate and supplier networks.
  • Harden and monitor remote access to substations and control centres, with authenticated, time-bound maintenance.
  • Tier and assure the vendors and integrators the network depends on.
  • Put control-centre-down and substation-down readiness in place, with rehearsed recovery that restores stability safely.
  • Maintain a live view of OT posture across a dispersed estate, and assure cyber at the point of digital-substation programmes.

Protected grid availability and system stability.

Reduced exposure across a dispersed substation estate.

Leverage over the vendors and integrators that can affect the network.

Demonstrable alignment to NIS / CAF, NERC CIP and IEC 62443.

Gas networks, Energy & Utilities
03Energy & Utilities

Gas networks

Transmission and distribution pipelines, compressor and pressure-reduction stations, and metering.

The problem

Gas networks run on pipeline SCADA, compressor and pressure-reduction stations and metering spread across vast, remote estates, frequently with limited physical security and ageing telemetry. A cyber incident that disrupts pressure control or telemetry is a safety hazard, not just an outage, and the Colonial Pipeline case showed how a business-IT compromise can force precautionary shutdown of the operational side.

  • OT Programme Design & Delivery
  • Site Enablement
  • OT Supply-Chain GRC
  • Readiness for major incidents
  • OT Security Due Diligence

How we solve it

  • Build an integrated view of pipeline SCADA, stations and telemetry, and design segmentation that respects remote-site constraints.
  • Harden and monitor remote access; remove ad-hoc remote-desktop and modem pathways at remote sites.
  • Map critical functions, pressure and safety control, to the systems and suppliers that support them.
  • Rehearse pipeline-down and telemetry-loss scenarios, including how IT and OT are isolated under response.
  • Assure cyber at the point of network capex and station upgrades.

Protected supply continuity and pipeline safety.

Controlled, monitored remote access across a dispersed estate.

Faster, rehearsed recovery when an incident hits.

Demonstrable regulatory alignment and a stronger position with regulators and insurers.

We come from the operational floor.

We have run multi-region OT security programmes across energy and other critical infrastructure. That matters here, where advice that ignores live operations and safety cases gets ignored on the ground.

We are vendor-, tool- and standard-agnostic. We map to what you already run and the frameworks you already answer to, and we leave you with capability, not dependency.
