The Operational Reality

Energy and utility operators are transforming at unprecedented scale. Electrification, decarbonisation and digitalisation are reshaping power, gas and water systems, while distributed energy resources, automation and remote operations become core to how networks run.

Yet much of the underlying operational infrastructure was built for a different era – one defined by centralised assets and physical isolation. That mismatch now represents one of the greatest sources of operational risk.

Energy environments now depend on:

  • Remote engineering and vendor access
  • Cloud-based SCADA and analytics
  • Distributed field assets and substations
  • DER, EV charging and grid-edge systems
  • Mobile operational workforces


What were once air-gapped systems are now interconnected ecosystems – and failures have immediate, physical consequences.

Why This Is a Strategic Inflection Point

Energy operators must modernise, without compromising continuity.

Rising Compliance

Regulatory frameworks such as NIS2, CER and NERC CIP demand demonstrable operational control

Governance Gap

IT and OT have converged operationally, even if governance has not

Autonomous Operations

Machine-operated systems now control critical national infrastructure

Lifecycle Risk

Long-lived assets must remain secure for decades – not just audit cycles

The new requirement

Resilience in modern energy systems depends on:

Identity-Icon

Trusted identity for every machine and controller

audit-icon

Governed access across sites, partners and vendors

Secure-network-icon

Secure, segmented operational networks

crypographic-trust

Cryptographic trust that will endure asset lifecycles

Icon-continious

Continuous assurance for regulators and boards

How Xalient Helps

Xalient secures OT environments end-to-end by unifying identity, cryptographic trust and secure operational networking into a single operating model.

Converged OT/IT
Identity Security & Networking

Consistent, auditable control of who and what can access critical operational systems.

Xalient enables utilities to:

  • Establish identity governance for employees, field teams and external vendors

  • Govern machine identities across PLCs, RTUs, sensors and gateways

  • Control privileged access for engineering and maintenance activities

  • Automate certificates and credentials across OT assets

  • Align identity and access controls with IEC 62443, NIS2 and regulatory requirements

Secure
Operational Networking

Resilient operational connectivity that enables grid modernisation without increasing risk.

Xalient enables utilities to:

  • Segment networks to protect critical control systems

  • Secure connectivity between plants, substations and cloud platforms

  • Control and monitor vendor and partner access

  • Enforce consistent trust, visibility and policy through MARTINA as the operational control plane

Digital Trust, PKI
& Post-Quantum Readiness

A future-proof trust foundation for energy and utility infrastructure that must operate securely for decades.

Xalient enables utilities to:

  • Discover and map cryptographic dependencies across operational systems

  • Modernise PKI and automate certificate lifecycle management

  • Reduce outage risk caused by expired or weak credentials

  • Design crypto-agile architectures aligned with post-quantum standards

Why Xalient

Xalient brings deep experience across energy, utilities, and other critical infrastructure environments, where security decisions directly affect safety, availability, and regulatory compliance. We specialise in identity, cryptographic trust, and operational networking for complex operational landscapes.

We are vendor-independent and integration-led, focused on selecting and connecting the right technologies rather than promoting a single solution. This ensures architectures that fit operational reality, regulatory requirements, and long-term asset lifecycles.

Our services span advisory, design, deployment, and managed operations, allowing us to support organisations end to end, from strategy through to day-to-day control.

Everything we do is focused on measurable outcomes: safety, continuity, and regulatory confidence.
