The new OT reality

Industrial operations across every sector are becoming more connected, automated and data-driven. OT environments that were once isolated are now integrated with enterprise IT, cloud platforms, vendors and remote operations.

OT systems were designed for safety, stability and uptime – not continuous connectivity. Today, operational environments depend on:

  • Remote monitoring and engineering access
  • Cloud-based analytics and telemetry
  • Wireless sensors and gateways
  • Vendor-managed equipment
  • Mobile maintenance teams
  • Real-time data exchange with IT systems

The result is a growing gap between how OT environments operate and how they are secured.

Common OT challenges

Ageing control systems

PLCs, RTUs, HMIs and control networks were never designed for cloud-era integration.

Rapid growth of connected assets

Sensors, gateways and edge devices expand operational capability – and the attack surface.

Machine identity sprawl

Controllers, devices and embedded accounts often lack lifecycle governance or cryptographic hygiene.

Fragmented visibility across sites and environments

OT estates are distributed, but trust and access controls are often inconsistent.

Increased reliance on vendors and third parties

Remote access is essential – yet frequently unmanaged and difficult to audit.

Rising regulatory and customer expectations

Standards such as IEC 62443 and NIS2 require demonstrable, continuous operational control.

What OT Operators Need Today

To operate safely and competitively, organisations need an approach that is built for real-world OT:

Identity-Icon

Trusted identity for every person and every machine

audit-icon

Governed, auditable access across IT and OT

Secure-network-icon

Secure operational networking that limits blast radius

Visibility-icon

Visibility across all sites, assets and vendors

Icon-continious

Continuous assurance that systems remain under control

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 from corporate IT through to industrial control systems.

Xalient enables organisations to:

  • Establish identity lifecycle governance for engineers, vendors and operators
  • Govern machine identities across PLCs, sensors, gateways and embedded systems
  • Control privileged and remote access to operational environments
  • Integrate OT access into enterprise IAM, PAM and access policies
  • Align OT environments to IEC 62443 and regulatory expectations

Secure
Operational Networking

 Resilient connectivity that supports transformation without increasing risk

Xalient enables organisations to:

  • Modernise networks for multi-site and hybrid operations
  • Segment environments to protect critical control systems
  • Secure connectivity to cloud platforms and vendors
  • Control and monitor third-party access
  • Enforce consistent trust and policy across the OT estate through MARTINA

Digital Trust, PKI
& Post-Quantum Readiness

A future-ready trust foundation for automation and long-lived assets.

Xalient enables organisations to:

  • Discover and inventory certificates and cryptographic dependencies
  • Modernise PKI and automate certificate lifecycle management
  • Reduce operational risk from expired or weak credentials
  • Design crypto-agile architectures aligned with post-quantum standards
  • Integrate cryptographic trust into identity and network controls

Why Xalient

Xalient specialises in identity-driven security and operational networking. We bring deep experience across industrial and critical infrastructure environments, where security decisions directly impact safety and continuity.

We are vendor-independent and integration-led, focused on connecting the right technologies rather than promoting a single solution. Our services span advisory, design, deployment, and managed services, allowing us to support organisations end to end.

With global reach and strong local relationships, we combine scale with hands-on execution. Everything we do is focused on measurable outcomes: safety, continuity, and control.
