The Visibility Gap
Manufacturing · Operational Technology · Industrial Security

The factory floor went online.
The security model stayed behind.

For decades, operational technology security meant one thing: physical isolation. Air-gapped systems. Plant engineers who'd run those machines for 20 years. Then IIoT happened. Remote monitoring happened. Cloud analytics happened. The air gap is gone. The security model didn't update.

Two worlds that were never meant to meet.
Now they have to be governed together.

How most manufacturers still operate

IT and OT: Separate Kingdoms

The IT team secures the enterprise. The OT team runs the plant. Both teams are good at their jobs. Neither one owns the intersection.

Most manufacturers have no unified asset inventory that spans IT and OT. No segmentation policy that's been formally tested. No incident response plan that covers a production shutdown. And no board-level visibility into what's actually at risk on the factory floor.

The attackers figured this out first.

What leading manufacturers are building

Converged, Visible, Governed

A unified security posture doesn't mean replacing OT with IT practices. It means building governance that spans both — with visibility into what's running, what's connected, and what happens if any of it is disrupted.

This model gives boards real oversight. It gives operations teams a shared language with security. And it's the only model that catches attacks before they reach production.

"You can't govern what you can't see.
And right now, most plant floors are dark."

The 5 questions your operations leadership
should be able to answer — and usually can't.

Every question below is one that determines real operational exposure. None of them are answered by an annual IT audit.

Every manufacturing environment has the same architecture.

Once you map the OT environment the same way you'd map any security domain — with defined systems, owners, and risk surfaces — the gaps become visible. And so does the path to addressing them.

Manufacturing System Security Domain What We Assess
PLCs, controllers, HMIs The automation backbone Device inventory, firmware/patch status, authentication, configuration integrity
IT/OT boundary and DMZ The perimeter Where visibility ends, segmentation controls, monitoring coverage
Remote access paths Side entrances Vendor VPNs, jump servers, MFA enforcement, active credential audit
SCADA / DCS systems The control center Change management, access controls, historian exposure, version currency
IIoT sensors and edge devices The nervous system Device discovery, authentication, protocol segmentation, update paths
Production data flows The circulatory system What data moves where, ERP/SCADA integration, historian connections, cloud feeds
Vendor and contractor access Third-party exposure Who has access, when was it last reviewed, what devices do they use
OT security monitoring Vital signs What you're watching — and what you're missing

The visibility your board needs.
The roadmap your operations team can use.

Information Security Enterprise Risk Assessment (ISERA)

A 30-business-day structured assessment that examines both sides of the IT/OT boundary — together. Workshops with IT leadership, operations management, and plant engineers. A perception gap analysis that reveals where the security team and the operations team see risk differently (they always do). A risk register built from your actual environment. And a prioritized roadmap your board can govern with.

Passive OT discovery — asset inventory built without disrupting production
IT/OT boundary mapping — exactly where the exposure begins
Perception gap analysis — where security and operations teams disagree on risk
Prioritized roadmap — sequenced by operational impact, not just technical severity
Board-ready reporting — one shared language for technical and executive leadership
Framework-agnostic — satisfies NIST CSF 2.0 Mfg Profile, IEC 62443, CMMC, and HIPAA risk requirements simultaneously

Satisfies risk assessment requirements across:

NIST CSF 2.0 IEC 62443 NIST 800-82 CMMC 2.0 HIPAA NIS2
