Capabilities

OT-native cybersecurity from architecture to operations.

Our work supports asset owners, asset stewards, project directors, system integrators and vendors delivering OT and ICS solutions into regulated environments. Engagements are scoped to plug directly into existing project structures and governance cycles.

Embedded OT specialists

Subcontracted OT security architects, SMEs and consultants who integrate into your delivery, engineering or cyber governance teams.

OT Cyber SMEs & Consultants
Project & assurance support

Security architecture & SADs

Reference architectures, Security Architecture Documents, drawings and governance-ready design artefacts that survive design reviews, gate approvals and handover.

Security Architecture Documents
Zone & conduit drawings
Design artefacts for governance

Independent OT assurance

Independent reviews of OT security posture, project deliverables and vendor solutions — aligned to IEC 62443, NIST and Australian critical infrastructure obligations.

Independent cyber assurance
Design & build audits
Operational acceptance reviews

OT-aligned security testing

Penetration testing and security testing methodologies that respect OT availability, safety constraints and engineering change controls — never a copy-paste of IT testing.

OT-safe penetration testing
FAT / SAT cyber testing
Vulnerability validation

Vendor security risk support

Independent support during vendor security negotiations — clarifying obligations, reviewing responses and protecting the asset owner's risk position through procurement and delivery.

Vendor risk negotiation
Cyber schedule review
Contract & handover obligations

Operational handover

Support for operational acceptance, cyber handover, residual risk capture and the practical work of moving OT systems from build into steady-state operations.

Cyber handover packs

Built for OT, not adapted from IT

Architecture that respects how operational systems actually run.

OT environments fail differently to IT. Availability, safety, change windows, supplier obligations and long asset lifetimes all shape what good security looks like. We design and document reference architectures, segmentation models and zone-and-conduit diagrams that align to recognised industrial standards and remain usable through the full asset lifecycle.

Where we work

Sectors and environments we understand.

We focus on the environments where availability, safety and cyber risk meet — and where engineering, project and cyber governance teams must work together to deliver outcomes that hold up under regulatory scrutiny.

Rail & Transport

Signalling, traction, communications, depot and control centre systems — the OT estate that keeps networks moving.

NSW Government Projects

OT cyber inputs for major projects, programs and asset stewards — registered on the NSW SCM0020 ICT Services Scheme.

Critical Infrastructure

Energy, water, gas and utilities exposed to the Australian critical infrastructure regime — including SOCI obligations.

Industrial Facilities

Process, manufacturing and logistics environments where ICS, SCADA and engineering systems support operations.

Project Delivery Teams

Embedded support for project directors and integrators delivering OT systems into asset-owning organisations.

Vendors & Integrators

Independent technical support for system integrators, authorised service providers and OT solution vendors.

Our approach

Risk-based. Standards-aligned. Built to be audited.

Every engagement is shaped around the asset, the obligations and the people who will own the outcome. We anchor our work to recognised industrial standards and the realities of Australian critical infrastructure obligations — so deliverables stand up to design reviews, gate approvals and assurance audits.
