Energy & Critical Infrastructure

Systems built to run for decades, inside a security regime that changes every year.

Industry Overview

Your operational technology was engineered for availability and physical safety, much of it for a world where it was never meant to be connected. Those systems still run the grid, the plant and the network — and they now sit inside regulation that treats them as part of the attack surface.

IT and OT are usually owned by different teams, with different vendors and different ideas of what secure means. The regulator sees one entity, and expects one answer.

Industry Challenges

Three recur across generation, networks and utilities — regardless of scale.

[01]
One entity, two security worlds

Controls designed for office IT do not translate to a control system that cannot be patched on a Tuesday. You need one defensible picture across both, without forcing one world’s methods onto the other.

[02]
Suppliers inside your perimeter

Vendors maintain, update and remotely access systems you are accountable for. NIS2 makes their security part of your obligation, and the CRA changes what they owe you.

[03]
Long lifecycles, short compliance clocks

Assets designed for thirty years of service now face reporting deadlines measured in hours and requirements revised every few years. Keeping them compliant is an engineering program, not a documentation exercise.

Regulatory & Compliance Landscape

As an operator of essential services, you answer to cyber regulation at entity level, product rules that reach into your procurement, and sector requirements on top. Together they set the bar for cyber-physical systems to be built, operated and evidenced as both safe and secure.

NIS2

Energy entities are essential entities: risk management measures, supply chain security, incident reporting that starts within 24 hours, and management accountability. Supply chain security carries more weight each year — inherited components are a faster route in, and the directive is written to have that addressed from the start rather than after an incident. Targeted amendments proposed in January 2026 are still in negotiation.

CER Directive

Critical entities were due to be designated by July 2026. Once notified, they have months to meet resilience obligations beyond cyber — and fall inside NIS2 regardless of size.

Cyber Resilience Act

Vulnerability reporting applies since September 2026 and the full requirements from December 2027, reshaping what OT vendors must deliver and support.

IEC 62443

The reference series for industrial automation and control system security — for operators, integrators and component suppliers alike.

Network Code on Cybersecurity

Sector rules for cross-border electricity flows, adopted in 2024 and phasing in over the following years.

How NG Intelix Helps

IT and OT converged. The assurance around them did not. These three engagements start from the second problem.

[01]
DevSecOps Assessment

The pipeline that produces and deploys your operational software, measured against what it claims to enforce: build integrity, artifact provenance, and who can push a change into an environment that controls physical plant.

[02]
Supply Chain Security

What is actually inside the systems you operate — including the components your suppliers inherited without specifying them, and the remote access those suppliers still hold.

[03]
Cyber Resilience Advisory

NIS2 risk management measures and IEC 62443 expressed as technical controls your engineers can implement and your management can be accountable for.

Outcome

A smaller chance of industrial control disruption or an unauthorized override, and a clearer position on uptime and physical safety across distributed assets — including knowing which dependency a newly disclosed vulnerability actually touches.
