Description

A focused course, tailored for you

OT Security Consulting: From Assessment to Roadmap

Build the client-ready methodology that turns a 200-item OT vulnerability list into a funded remediation program operations leadership will execute.

The assessment report lands. The client's operations director asks which findings require a plant shutdown to remediate. You have the vulnerability count. You don't have the plant-impact triage. That gap, between a technically complete assessment and a remediation roadmap that survives budget and scheduling scrutiny, is where OT consulting engagements lose momentum.

Why this course

OT security consultants with strong technical skills regularly hit the same delivery wall: the findings are real, the framework mapping is correct, and the client nods along until someone from operations asks a question the assessment methodology was never designed to answer. Which assets run safety instrumented systems? Which vulnerabilities can be patched live versus during a scheduled outage? What does remediation look like to the shift supervisor who has to sign off on it? These are not IT security questions. They require a different prioritization logic, a different risk register format, and a completely different business case structure than an IT security engagement. This course delivers that methodology.

What you walk away with

Produce a zone-conduit diagram grounded in a client's actual brownfield architecture using IEC 62443-3-3 as the design criteria.
Triage a vulnerability list by operational impact using an OT-adapted scoring model where availability outweighs confidentiality.
Sequence a remediation roadmap that separates quick wins from long-cycle hardware replacement and shows client leadership visible progress before the long-cycle work begins.
Write a risk register in the operational language of production downtime and safety events, not IT ticket terms.
Build a board-ready business case for OT security investment that competes credibly against capital expenditure decisions in the same budget cycle.

The 12 modules

Module 1. Scoping the OT Engagement

Starting an OT security engagement correctly requires understanding which assets are in scope before you walk onto the plant floor. This module covers brownfield versus greenfield scoping decisions, how to negotiate access to Level 0 and Level 1 assets without triggering operational restrictions, and how to frame the engagement scope in terms plant managers understand. You will build a scope definition template that operational stakeholders can sign off on without a cybersecurity background.

Module 2. Purdue Reference Model and IEC 62443 Zone Architecture

The Purdue model gives clients a language for OT network segmentation, but applying IEC 62443 zone-and-conduit logic to brownfield environments requires interpretation, not just mapping. This module walks through Levels 0 through 5, the IEC 62443-3-3 system requirements for zone definition, and how to identify conduit paths already implicit in a client's network topology. Output: a zone-conduit diagram template grounded in the client's actual architecture.

Module 3. OT Asset Discovery Without Disrupting Operations

Active scanning kills PLCs. Passive discovery tools miss assets that transmit infrequently. This module covers the decision matrix for passive versus active versus hybrid discovery approaches, how to work with operations staff to walk the floor as a discovery method, and how to reconcile P&ID drawings against your asset inventory. You will leave with a discovery methodology that operations engineers will cooperate with rather than block.

Module 4. Framework Mapping for OT Security Engagements

NIST SP 800-82 revision 3, IEC 62443, NERC CIP, TSA Pipeline Security Directives, and NIS2 each address OT security from a different regulatory angle. This module maps the overlap and gaps across frameworks, explains where IEC 62443 security levels translate to NERC CIP requirements, and shows how to select the right framework combination for a client's sector and regulatory jurisdiction. Output: a client-ready framework applicability matrix.

Module 5. Adapting CVSS for OT: Prioritizing by Operational Impact

CVSS scores built for IT environments rank confidentiality above availability. In OT environments that ranking inverts. This module covers OT-specific vulnerability scoring approaches including the CVSS adaptations in NIST SP 800-82 and IEC 62443-2-4, how to layer in operational context such as whether an asset is part of a safety instrumented system, and how to produce a triage list a plant manager will recognize as actionable rather than theoretical.

Module 6. IT/OT Convergence Assessment: Where IT Controls Break

Clients applying IT security controls to OT environments create new risks. Patching cycles, endpoint detection agents, and Active Directory group policies that work fine in corporate IT can cause unexpected behavior in PLCs and HMIs running on real-time operating systems. This module covers the methodology for identifying incompatible IT control overlaps, the conversation framework for explaining the conflict to IT security teams, and the remediation path for each category.

Module 7. Building the OT Risk Register Operations Leadership Will Act On

An OT risk register written for an IT audience uses language plant managers cannot translate into operational decisions. This module redesigns the risk register fields for OT context: consequence framing in production downtime and safety event terms, likelihood calibrated to threat actor access paths specific to industrial systems, and risk treatment options that reference maintenance windows rather than IT ticket queues. Output: a risk register template in the client's operational language.

Module 8. Remediation Sequencing: Quick Wins Against Long-Cycle OT Hardware

OT remediation roadmaps fail when they front-load hardware replacement that requires a plant shutdown two or more years out. This module covers the sequencing logic for separating network architecture changes from configuration hardening and compensating controls, how to build a phased roadmap that shows visible progress before the long-cycle work begins, and how to price and scope each phase for change management approval by the client's operations and finance teams.

Module 9. Network Segmentation Design for OT Environments

Firewall placement between IT and OT zones, unidirectional security gateways for historian data flows, and DMZ architecture for remote access are the three OT network segmentation decisions clients ask about most. This module covers the design criteria for each, how to evaluate commercial OT visibility platforms against IEC 62443-3-3 system requirements, and how to write the network segmentation specification that both IT architects and OT engineers can implement in a brownfield environment.

Module 10. Building the Business Case for OT Security Investment

Operations leadership funds OT security spend when it is framed as production risk, not cyber risk. This module covers the financial modeling approach for OT security return on investment, how to translate a risk register into production downtime scenarios with estimated cost ranges, and how to structure the board presentation so the remediation roadmap competes credibly against capital expenditure decisions in the same budget cycle. Output: a business case slide template for operations-audience presentations.

Module 11. Regulatory Mapping for OT Security Engagements

Clients in energy, utilities, oil and gas, and manufacturing each face different OT security regulatory obligations. This module maps NERC CIP for bulk electric system operators, TSA Pipeline Security Directives for natural gas and liquids operators, NIS2 for European critical infrastructure, and ISA/IEC 62443 certification paths for operators seeking third-party assurance. Output: a sector-by-sector regulatory obligation matrix you can use as a discovery tool at the start of each new client engagement.

Module 12. Client-Ready Deliverables for OT Security Engagements

The assessment report, the executive summary, the technical appendix, and the remediation roadmap are four documents with four different audiences. This module covers the structure and language calibration for each, how to write an executive summary an operations director will forward to the board rather than table for later, and how to package the full engagement output as a consulting deliverable set that supports upsell into remediation implementation work.

How this addresses your situation

Specific modules that map to what you said you are dealing with.

Client asks which findings require a plant outage to remediate: Module 5 (OT CVSS triage) combined with Module 8 (remediation sequencing) produces the answer in a format the operations team can act on.

Client's IT team wants to deploy endpoint detection agents on the SCADA historian: Module 6 (IT/OT convergence) covers the incompatibility assessment and the compensating control path.

Finance team asks for the return on investment model before approving remediation budget: Module 10 (business case) walks through the production-downtime cost modeling approach.

Client needs to know which regulatory frameworks apply to their gas distribution network: Module 11 (regulatory mapping) maps TSA Pipeline Security Directives and NIS2 obligations by sector, with an output matrix you can use at the start of each engagement.

Before and after

Before

You deliver a technically complete OT assessment. The findings are real and the framework mapping is correct. But the remediation roadmap stalls in client review because operations leadership cannot translate the risk register into budget decisions and maintenance scheduling.

After

You deliver an assessment and a remediation roadmap that speaks the client's operational language. The risk register uses production downtime framing. The roadmap sequences quick wins before long-cycle hardware replacement. The business case model is ready for the budget committee. The engagement has a clear path to implementation work.

What happens if you do not address this

OT security assessments that do not convert into funded remediation programs leave the client exposed and leave the consulting relationship at risk. Without a delivery methodology that bridges technical findings and the client's operational decision-making process, the assessment becomes a shelf document rather than a mandate for change.

Who it is for

OT cyber security practitioners in consulting or advisory roles who lead client engagements, deliver assessment outputs, and are responsible for producing remediation roadmaps that clients can fund and execute. Typically working across energy, utilities, oil and gas, manufacturing, or critical infrastructure clients. Strong on the technical assessment side and looking to build the consulting delivery layer that makes the assessment work land.

Who this is NOT for. IT security consultants looking to transition into OT with no field exposure. This course assumes you can already read a Purdue model diagram and hold a conversation with a control systems engineer. It builds the next layer: structured delivery methodology, client-ready outputs, and the prioritization logic that operations leadership responds to.

How it arrives

Text-based course in the Art of Service learning environment, plus downloadable templates and worked examples for every module, plus the hand-built implementation playbook delivered alongside course access.

Time investment. Each of the 12 modules is designed for a focused 45 to 60 minute session. Most practitioners work through the course over two to three weeks, applying each module to an active or recent engagement as they go.

Why $199 is the right number

Public OT security courses cover the technical frameworks. Most stop at the assessment layer. This course covers the delivery methodology that converts technical findings into client-ready outputs, funded roadmaps, and the engagement extension conversations that follow. It is built for practitioners who can already read the framework, not for those starting from zero.

FAQ

Is this relevant if I work on both ICS and IT security engagements?

Yes. The course is built around the specific places where OT engagement delivery diverges from IT security consulting, particularly in prioritization logic, risk register language, and the business case model for operations audiences. The IT security skills you already have are the prerequisite, not the subject.

Does the course cover specific sectors like energy, oil and gas, or manufacturing?

Module 11 maps regulatory obligations sector by sector. Modules 4 and 9 cover framework and network architecture decisions with examples drawn from energy, utilities, and industrial manufacturing contexts. The core delivery methodology applies across sectors; the regulatory mapping module is where sector-specific obligations are addressed directly.

How is this different from IEC 62443 certification courses?

IEC 62443 certification courses teach the standard. This course teaches how to apply the standard inside a client consulting engagement: how to scope it, how to prioritize findings using it, how to write deliverables that clients and regulators can act on. The two are complementary rather than overlapping.
