OT Risk Assessment

Structured risk identification, analysis, and treatment planning for industrial control system environments. We evaluate threats across safety, operational, financial, and regulatory dimensions to build a risk treatment plan aligned with how your operations actually work.

Knowing What Matters Most

A vulnerability scan might flag 200 CVEs across your plant. A risk assessment tells you which five could actually cause a safety incident, which ten could halt production, and which ones are low-priority findings on isolated test equipment. The difference between the two determines whether your remediation budget addresses real risk or chases noise.

In OT, risk is not just about data. A compromised controller on a cooling water system carries different consequences than one on a metering skid. We evaluate every finding across four dimensions: safety impact, operational disruption, financial loss, and regulatory exposure, then score them against your specific facility context.

The output is a prioritized risk register with treatment plans mapped to your maintenance calendar, capital budget cycle, and operational priorities. Not a spreadsheet of CVEs, but a decision-ready document your leadership team can act on.

Risk-Based Approach

Quantifying risk in terms of operational, safety, and regulatory impact

Engagement Methodology

Each phase is designed to deliver measurable progress while respecting the operational constraints of live industrial environments.

01
Phase 1

Requirement Understanding and Scope Definition

Establish the assessment boundaries, objectives, and success criteria. Identify the systems, zones, and processes in scope. Align on the risk framework to be applied and define the assessment timeline around operational constraints and maintenance windows.

02
Phase 2

Stakeholder Kick-off and Coordination

Conduct kick-off sessions with plant operations, engineering, IT, and management stakeholders. Define roles, responsibilities, and communication protocols. Establish access requirements, safety briefings, and site-specific procedures for the assessment team.

03
Phase 3

Documentation Collection and Pre-Assessment Review

Gather existing documentation including network diagrams, asset inventories, previous assessment reports, security policies, incident logs, and change management records. Perform a desk-based review to identify preliminary areas of concern before on-site work begins.

04
Phase 4

Threat Understanding and Asset Analysis

Develop a threat profile specific to the facility and sector. Categorize assets by criticality based on their role in safety, production continuity, and regulatory compliance. Map threat actors, attack vectors, and historical threat intelligence relevant to the operational environment.

05
Phase 5

On-Site Assessment

Conduct physical walkthroughs and interviews with operators, engineers, and administrators. Verify network architecture against documentation, inspect physical security controls, observe operational practices, and identify deviations between documented procedures and actual implementation.

06
Phase 6

Configuration Review

Analyze configurations of firewalls, switches, servers, and industrial endpoints. Evaluate access control lists, segmentation enforcement, remote access configurations, and authentication mechanisms. Identify misconfigurations, default credentials, and policy violations.

07
Phase 7

Vulnerability Identification

Identify technical vulnerabilities across OT assets using passive reconnaissance, vendor advisory correlation, and configuration analysis. Cross-reference findings against NVD, ICS-CERT advisories, and the CISA Known Exploited Vulnerabilities catalog without active scanning of production systems.

08
Phase 8

Risk Analysis

Evaluate each identified risk by combining threat likelihood with consequence severity across four dimensions: safety impact, operational disruption, financial loss, and regulatory non-compliance. Apply a structured scoring methodology to produce quantified risk ratings for each finding.

09
Phase 9

Risk Prioritization and Risk Register

Consolidate all findings into a comprehensive risk register. Prioritize risks based on their composite score and the organization's risk appetite. Group related findings to identify systemic issues and highlight risks that require immediate attention versus those suitable for planned remediation.

10
Phase 10

Mitigation Strategy and Risk Treatment Plan

Develop a risk treatment plan that specifies recommended controls, compensating measures, and acceptance criteria for each risk. Align remediation activities with plant maintenance schedules, capital planning cycles, and operational priorities. Define a phased roadmap with clear milestones.

11
Phase 11

Report Preparation

Compile the complete assessment into a structured report including an executive summary, detailed technical findings, the risk register, and the treatment plan. Deliver a board-level summary alongside the full technical report to support decision-making at all organizational levels.

12
Phase 12

Implementation Support and Closure

Present findings to stakeholders, answer technical questions, and provide guidance on implementing the recommended controls. Offer post-assessment support to assist with remediation planning, vendor coordination, and validation of implemented measures. Formally close the engagement with a knowledge transfer session.
