OT Programme Design & Delivery.

Most OT security programmes don't fail at strategy. They fail somewhere between board approval and the plant floor. We design programmes that survive contact with running operations — and then we deliver them alongside your teams.

Engineered by us. Owned by you.

01 · The gap in the market

Everyone will write you a roadmap. Almost nobody will run it.

There is no shortage of OT security advice. There is a severe shortage of people who can hold a programme together through a shutdown, a safety case, a change freeze and a vendor dispute — and still land the control that was promised to the board. That is the gap, and it is where programmes die.

Big-four consultancies

Strategy without a plant floor

A polished target operating model, a maturity heatmap, and a delivery phase that quietly becomes your problem. The people who wrote it have never taken a line out of service.

We design it and then deliver it.

System integrators

Delivery without accountability for risk

Excellent at installing what they were told to install. Less willing to challenge whether it reduces operational risk, or to own the outcome when it does not.

We own the outcome, not the scope of supply.

IT security functions

Controls that break production

Enterprise patterns pushed into an environment that cannot tolerate them. Agents on assets that must not be touched. Programmes stalled by an engineer’s legitimate “no”.

We translate both ways, credibly.

In-house OT teams

Capacity, not capability

They usually know exactly what needs doing. What they lack is the bandwidth, the programme discipline and the board-facing evidence to get it funded and finished.

We add hands, not headcount.

02 · What we do

Design the programme. Then stay for the delivery.

We take responsibility for the whole arc: the evidence that justifies the spend, the architecture and standards that make it coherent, the plan that respects maintenance windows and safety cases, and the hands-on delivery that turns it into commissioned, operable control.

Then we hand it over properly — documented, tested, and owned by the people who run the plant. Built in, not bolted on.

Board to floor · one accountable team

Six workstreams. One programme.

01

Programme design & business case

Scope, sequencing, cost and the risk argument the board will fund — built from operational consequence, not control counts.

02

OT security architecture & standards

Zones and conduits, remote access, boundary design, secure-by-design patterns and the standards estate-wide delivery is measured against.

03

Regulatory & assurance alignment

CAF, NIS2, IEC 62443 and CRA obligations mapped into the programme itself, so compliance is a by-product of delivery rather than a parallel effort.

04

Delivery leadership & PMO

Programme and workstream leadership that speaks engineering, holds vendors to account, and runs the change control in your process, not ours.

05

Modernisation & migration

Safe replacement of end-of-life control systems, network refreshes and cloud/edge introduction — planned around windows, safety cases and production commitments.

06

Handover, capability & operate

Documentation, runbooks, training and the operating model that lets your own teams run what we built, and evidence it afterwards.

03 · How we deliver

Five stages. Each one ends in something operable.

01FrameUnderstand the operation, the estate and the constraints. Establish what “good” means in your context and what the board has actually bought.Programme charter & risk baseline
02DesignArchitecture, standards and a delivery plan sequenced against maintenance windows, safety cases, change freezes and vendor lead times.Target architecture & funded plan
03MobiliseGovernance, roles, vendor packages and controls put in place so delivery starts with owners named and decisions unblocked.Mobilised delivery structure
04DeliverHands-on execution alongside your teams — engineering, commissioning, testing, and honest reporting when reality moves the plan.Commissioned, tested controls
05Hand overDocumented, trained, operable. Ownership transfers to your teams with the evidence pack regulators and auditors will ask for.Owned by you, evidenced

04 · What you get

Deliverables that outlive the engagement.

Board-ready programme case

Scope, cost, sequencing and the operational risk argument, written so a non-technical board can approve it and a regulator can read it.

Target OT security architecture

Zones, conduits, remote access and boundary design for your estate — plus the migration path from what you have today.

Standards & secure-by-design patterns

Reusable specifications your engineers and integrators build to, so the next project inherits the control instead of relitigating it.

Delivery plan that respects operations

Milestones mapped to real windows, freezes and safety cases — a plan the plant agrees to rather than one imposed on it.

Assurance & compliance evidence

CAF, NIS2 and IEC 62443 alignment produced as the programme runs, indexed the way auditors ask for it.

Handover pack & capability uplift

Runbooks, as-built documentation, test results and the training that makes your teams the owners — not us.

05 · Why Nuvantiq

The instincts of operators, not the theory of advisors.

01

We have run plants, not just projects

Our engineers have written the PLC code and recovered the plant. That credibility is why operations lets us near the process.

02

Operational risk is the unit of measure

We argue in lost production, unsafe states and downtime with real consequence — not control counts and CVSS scores.

03

One accountable team, board to floor

The same people write the business case, defend it to the board, and stand on the plant floor at commissioning.

04

Engineered by us, owned by them

Success is your team operating what we built, confidently, after we have gone. No dependency, no alphabet soup, no vendor speak.

For the board & the CISO

You have approved investment and need evidence it is landing. We give you a programme with defensible scope, measurable milestones and regulatory alignment — CAF, NIS2, IEC 62443, CRA — reported in the language of operational consequence rather than control counts.

For engineering & operations

You have a plant to run and no appetite for security theatre. We work to your change process, your windows and your safety case — and we leave you controls you can operate, document and defend without calling us back.

Resilience isn't inherited. It's engineered.

Bring us the programme that has stalled, or the one you haven't started.

We will tell you plainly what it takes to land it.
