OT Security Adoption & Site Enablement.

A standard published at head office changes nothing at the plant gate. We take group policy to the shop floor site by site — hands on the cabinets, engineers in the control room — and leave each site running the controls itself.

Adoption is measured on site, not in a policy register.

01 · The gap in the market

The standard is written. The plant hasn't heard of it.

This is the last mile of OT security, and it is where most estates quietly fail. Group publishes a standard; sites are asked to “comply” with no time, no budget and no one who can safely touch a live control system. Compliance becomes a spreadsheet exercise, the plant carries on as before, and the risk never actually moves.

01

Where the estate is governed

Central IT, group security, the platform. Mature, monitored, well understood.

02

Where the standard is written

Policy, baselines and configuration authored a long way from any process.

03

Where it has to land

Live production, legacy controllers, one maintenance window a year, and no spare hands.

The gap is between the second frame and the third. Nobody crosses it for you.

Group security functions

A standard with no delivery arm

The policy is sound. What is missing is anyone with the OT competence and the site relationships to make twelve plants actually do it — so adoption is self-reported and unverified.

We are the delivery arm on the ground.

Consultancies

They stop at the gap analysis

A per-site maturity score and a list of recommendations. Nobody opens a cabinet, touches a switch configuration or stands in a night-shift handover.

We do the engineering, not the scoring.

System integrators

Project delivery, not adoption

They will install what is specified and leave. Nobody transfers the operating knowledge, so the control decays the first time it inconveniences production.

We hand over to trained owners.

Site engineering teams

No capacity for someone else’s mandate

The people best placed to do this are already running the plant. Group work lands on top of a full day and quietly slips — for entirely rational reasons.

We bring the hands, they keep the plant running.

02 · What it is

Adoption, not announcement.

We land your OT security standard at each site as working, operable control — configured, tested, documented and owned locally. Our engineers are the ones in the control room and at the cabinet: validating the asset inventory by walking the plant, hardening what can safely be hardened, and being honest about what cannot.

Then we build the site's own capability — named owners, tested runbooks, trained shift teams — so adoption survives after we leave. Engineered by us, owned by them.

03 · Real execution

What we actually do when we are on your site.

Not an assessment. This is the engineering work, done in your windows, under your permits, with your people alongside.

01

Plant walkdown & inventory validation

We walk the process areas and cabinets with your engineers and reconcile what is actually installed against the asset register — including the panel nobody has opened in years.

02

Network & cabinet-level work

Switch and firewall configuration, VLAN and zone implementation, cable and port discipline, removal of unmanaged devices and rogue connections found during walkdown.

03

Remote access implementation

Vendor and support access moved onto brokered, authenticated, time-boxed and recorded paths — then the old routes actually decommissioned, not just documented.

04

Hardening within safe limits

Account and credential clean-up, service reduction, HMI and engineering workstation hardening — each change assessed against vendor support terms and the safety case.

05

Backup & recovery you have tested

PLC, HMI and SCADA configurations backed up, held offline, and restored in a controlled test — so recovery is a proven procedure rather than an assumption.

06

Monitoring & log onboarding

Site telemetry and remote-access logs connected to the group SIEM or platform, tuned so the alerts that fire mean something to the people who receive them.

07

Change, permit & window discipline

Every intervention run through your change process, with method statements, rollback plans and a named site approver. We work the window we were given.

08

Verification & exception handling

Post-change testing against the standard, with honest, engineered exception records where a legacy system genuinely cannot comply — plus a compensating control that can.

04 · The rollout model

Prove it at one site. Then repeat it, faster, at the rest.

Estates do not get secured by simultaneous effort. They get secured by a pattern that works, applied in waves — each wave cheaper and quicker than the last because the template, the evidence and the objections are already known.

01Pilot siteThe hardest realistic site, not the easiest. We prove the standard is deliverable where it is genuinely awkward — legacy kit, tight windows, sceptical engineers.Proven pattern & real cost
02TemplatiseThe pilot becomes a repeatable site package: method statements, configuration baselines, evidence templates, training material and a realistic effort model.Reusable site playbook
03Wave deliverySites delivered in waves, sequenced around shutdowns and seasonal load, with the same engineers carrying the pattern forward so nothing is relearned.Sites completed, not started
04Local handoverEach site signs off with named owners, tested runbooks, trained shift teams and its evidence pack. Adoption is confirmed by the site, not asserted by us.Signed site acceptance
05Sustain & assurePeriodic spot-checks, refresher drills and support for the site’s own annual verification, so year two looks better than year one rather than worse.Adoption that holds

05 · Enablement

A control nobody at the site can operate is not a control.

Enablement is the half of this pillar that consultancies skip. We build the local muscle to run, verify and defend what has been installed.

Named site security owner

One person at each site who owns OT security day to day, with a defined remit, escalation path and the authority to say no — and the backing to make it stick.

Runbooks written for shift teams

Plain-English procedures for the things that will actually happen at 03:00: granting vendor access, isolating a device, restoring a controller, escalating an alarm.

Role-based training on your kit

Sessions delivered on site, on the equipment your engineers use, for control engineers, maintenance, shift operators and site leadership — no generic awareness slides.

Vendor management on the ground

We brief and onboard the integrators and OEMs your site depends on, so external engineers arrive already knowing the new access rules.

Response drills

A tabletop and a hands-on rehearsal of an OT incident at that site, with the people who would really be in the room — and a plan corrected by what the drill exposed.

Local evidence routine

A short, repeatable monthly and annual check the site can run itself, producing the evidence group and the regulator will ask for next time.

06 · What each site gets

A site pack that proves adoption happened.

Validated asset & connection register

What is actually on the plant floor and how it connects, confirmed by walkdown rather than inherited from a spreadsheet.

As-built configuration baselines

Network, remote access and hardening configurations as they now stand, so future change has a reference point and drift is detectable.

Site conformance & exception record

Line-by-line status against the group standard, with engineered justification and compensating controls for every exception.

Tested recovery evidence

Backup inventory plus the results of an actual controlled restore — the difference between a backup policy and a recovery capability.

Runbooks, training record & owners

The operating material, who was trained on it, and the named individuals now accountable at that site.

Compliance evidence pack

Per-site evidence mapped to CAF, NIS2 and IEC 62443, indexed the way auditors and group assurance ask for it.

07 · Why Nuvantiq

Site teams let us near the process. That is the whole job.

01

We have done the work, not just reviewed it

Our engineers have written the PLC code, configured the switch and recovered the plant. Site teams can tell within an hour, and it decides whether the programme moves.

02

We arrive with hands, not requirements

The site’s constraint is capacity. We add capability instead of adding tasks — which is why sites stop treating group security as an imposition.

03

Production comes first, and we mean it

Permits, windows, safety cases and rollback plans are how we work, not caveats. Nothing we do is worth an unplanned stoppage.

04

Success is us leaving

The site running its own controls, evidencing them without us, and calling only when it wants to. No dependency, no retainer disguised as adoption.

For group security & the CISO

You need to know the standard is real at every site, not just published. We give you consistent per-site evidence, a rollout you can forecast, and honest exception records where a site genuinely cannot comply — mapped to CAF, NIS2 and IEC 62443.

For the site & plant manager

You have production targets and a group mandate landing on top of them. We bring our own hands, work to your windows and permits, take the burden off your engineers, and leave you controls your shift teams can actually operate.

Built in, not bolted on. Site by site.

Start with one site.

We will show you what adoption looks like when engineers do it — then repeat it across the estate.
