Engagement  ·  OT & Industrial Cybersecurity Assessment See the Plant the Way an Attacker Would.

For oil and gas, energy, manufacturing and critical infrastructure. Asset visibility, IT/OT segmentation, remote and privileged access, vulnerability exposure, legacy systems, monitoring and incident readiness, assessed against IEC 62443 and the regional requirements that apply.

What this is

OT & Industrial Cybersecurity Assessment

An OT & Industrial Cybersecurity Assessment examines the systems that run physical processes: controllers, safety systems, historians, engineering workstations and the networks between them. It establishes what is actually connected, how the IT and OT networks are separated in practice, who can reach the plant remotely and with what privilege, and how an incident would be detected and contained, then maps the findings to IEC 62443.

Where You Stand

Four statements · self-check

Answer honestly.

0 / 4 ANSWERED

You have a current inventory of every asset on your OT networks, including the ones a vendor installed.

Traffic between IT and OT passes through a defined, monitored boundary, not a flat route.

Every remote access path into the plant is known, time-limited and logged.

You would detect an unauthorized change to a controller before it affected the process.

Deliverables

What You Get

01

OT Asset Inventory

Every controller, workstation and network device found, classified by function and criticality.

02

Segmentation Review

The IT/OT boundary as built, zones and conduits drawn, and every route that bypasses them.

03

Access Path Map

Remote, vendor and privileged access into the plant, with how each is authorized and logged.

04

OT Exposure Findings

Vulnerabilities and legacy systems ranked by what they could affect, with compensating controls where patching is not possible.

05

IEC 62443 Gap Assessment

Zones and controls measured against the standard, with the target security level stated.

06

Detection & Response Readiness

Whether an incident in OT would be seen, who would act, and what they are authorized to do.

Questions We Are Asked

Will the assessment disrupt operations?
No. The work is passive by default: architecture review, configuration review, and traffic captured from existing monitoring points. Any active test is agreed in writing with operations, scheduled in a maintenance window, and can be stopped by your team at any time.
Do you work with legacy systems that cannot be patched?
That is most of the job. Where a system cannot be patched or replaced, the assessment identifies compensating controls (segmentation, access restriction, monitoring) and records the residual risk for a named owner to accept.
Which standards apply?
IEC 62443 is the reference for industrial automation and control systems. Findings are also mapped to the regional requirements that apply to critical infrastructure in your jurisdiction, so one assessment serves both.
Is this separate from IT security?
It covers the boundary between the two, which is where most incidents cross. Organizations often pair it with a Cybersecurity Maturity & Risk Assessment, so IT and OT are measured on the same scale.
Can you monitor OT afterwards?
Yes. Managed Detection & Response can extend into OT networks with monitoring designed for industrial protocols, under an agreed authority that never lets an analyst act on a process without operations.
