Services

OT cybersecurity services that plug into your delivery model.

Engagements are scoped to fit your operating rhythm — from short specialist support across a single design package, to ongoing embedded resources across a multi-year program.

01 · Embedded specialists

OT security architects, SMEs and consultants — embedded in your team.

We provide subcontracted OT cybersecurity resources that integrate directly into your delivery, engineering, or governance functions. Whether you need a single Security Architect on a project gate, or a small embedded team across a program, our consultants work to your processes and report to your leads.

  • OT Security Architects
  • OT Cyber Subject Matter Experts
  • OT Cybersecurity Consultants
  • Specialist surge support for milestones & gates
  • Trusted advisor to project directors and cyber leads
02 · Security architecture

Security Architecture Documents and design artefacts that hold up under review.

Architecture is where OT cybersecurity becomes real. We produce reference architectures, Security Architecture Documents (SAD), zone-and-conduit drawings and other design artefacts that align to recognised industrial standards and survive scrutiny from cyber governance teams, assurance reviewers and operational owners.

  • Reference architectures & high-level designs
  • Security Architecture Documents (SAD)
  • Zone & conduit drawings and segmentation models
  • Remote access, monitoring & logging designs
  • Governance-ready design artefacts for gate reviews
03 · Independent assurance

Independent OT cybersecurity assurance and auditing.

We provide vendor-neutral assurance over OT cybersecurity programs, project deliverables and operational environments — giving asset owners and stewards an independent line of sight into risk, controls and residual exposure.

  • Independent design and build assurance reviews
  • OT cybersecurity posture assessments
  • Audit of vendor and integrator deliverables
  • Operational acceptance & handover assurance
  • Reporting tailored to executive, project and engineering audiences

04 · OT-aligned security testing

Penetration testing and security testing built around OT safety.

OT systems can't be tested the way IT systems are tested. We use approaches that respect availability, safety, change control and engineering constraints — and produce findings that engineering, operations and cyber teams can all act on.

  • OT-safe penetration testing methodologies
  • Cyber elements of FAT and SAT testing
  • Vulnerability validation and exploitability review
  • Configuration and hardening review against OT baselines
  • Joint planning with operations and engineering
05 · Vendor security support

Vendor risk negotiation and security obligations support.

We work alongside asset owners and stewards during procurement, design and delivery — helping to clarify vendor cyber obligations, review responses and protect the asset owner's risk position through to handover.

  • Cyber security schedule review and drafting input
  • Vendor response and ITT/RFT evaluation support
  • Independent technical challenge during negotiation
  • Tracking of cyber obligations through delivery
  • Closeout of vendor cyber deliverables at handover
06 · Operational handover

Operational acceptance and cyber handover support.

The moment a system moves from build to operations is where many OT cybersecurity programs lose ground. We work with project teams and asset stewards to make sure cyber outcomes — controls, documentation, evidence and residual risks — make the trip into operations intact.

  • Operational Acceptance Test (OAT) cyber inputs
  • Cyber handover packs & document control
  • Residual risk register and treatment plan
  • Transition of monitoring, patching and access
  • Lessons learned for the next stage of works
