OT Risk Assessment
Comprehensive evaluation of cybersecurity risks across your operational technology environment.
Part of our comprehensive OT GRC services: Security Governance | Risk Assessment | Regulatory Compliance
Service Overview
Our OT Risk Assessment service is a core component of our GRC (Governance, Risk, and Compliance) offering, providing comprehensive evaluation of cybersecurity risks across your operational technology environment. We combine technical analysis with business impact assessment to deliver prioritized recommendations that align security investments with organizational objectives.
Using industry-standard frameworks like IEC 62443 and NIST CSF, we identify threats, evaluate existing controls, and quantify potential impacts to help you make informed decisions about your OT security posture. Our methodology goes beyond simple vulnerability scanning to understand the real-world risks your organization faces based on threat actor capabilities, attack scenarios, and business criticality.
Key Benefits
Risk Prioritization
Prioritized risk register aligned with business criticality, safety implications, and operational impact. Focus resources on what matters most.
Clear Impact Analysis
Understand potential financial, operational, safety, and environmental consequences of cyber incidents in your OT environment.
Executive Reporting
Executive-ready reports for board and leadership communication with clear risk quantification and business context.
Compliance Mapping
Gap identification against relevant regulatory requirements including IEC 62443, NERC CIP, NIS2, and sector-specific standards.
Actionable Roadmap
Prioritized remediation plan with timelines, cost-benefit analysis, and implementation guidance aligned with your budget.
Framework Alignment
Assessment methodology aligned with IEC 62443-3-2 risk assessment requirements and NIST Cybersecurity Framework.
Our Methodology
Our risk assessment follows a structured approach that ensures comprehensive coverage while maintaining operational continuity.
Phase 1: Scoping & Planning
Define assessment boundaries, identify critical assets and processes, establish risk criteria aligned with business objectives, and coordinate with stakeholders.
Phase 2: Asset Characterization
Identify and classify OT assets by criticality, function, and business impact. Document asset dependencies, network connectivity, and data flows.
Phase 3: Threat Analysis
Identify relevant threat actors (nation-state, cybercriminals, insiders, hacktivists) and analyze attack scenarios specific to your industry and environment.
Phase 4: Vulnerability Correlation
Map identified vulnerabilities to threat scenarios, assess exploitability, and evaluate effectiveness of existing security controls.
Phase 5: Impact Assessment
Quantify potential consequences across safety, environmental, financial, operational, and reputational dimensions for each risk scenario.
Phase 6: Risk Calculation
Calculate risk scores based on likelihood and impact. Prioritize risks using a risk matrix aligned with your organization's risk tolerance.
Phase 7: Recommendations
Develop prioritized remediation roadmap with technical controls, process improvements, and compensating controls. Include timelines, budgets, and success metrics.

Frequently Asked Questions
How long does a risk assessment take?
Typical timeline is 4-8 weeks depending on environment size and complexity. This includes scoping, on-site assessment, analysis, and report development.
Do you need access to our production systems?
We primarily use passive monitoring, document review, and stakeholder interviews. Active testing is limited and coordinated to minimize operational risk.
How often should we conduct risk assessments?
Annual assessments are recommended, with interim reviews after significant changes (new assets, architecture changes, major incidents, or regulatory updates).
Can you assess multiple sites?
Yes. We can assess single sites or conduct enterprise-wide assessments across multiple facilities with consistent methodology and consolidated reporting.
What happens after the assessment?
We provide executive presentation, answer questions, help prioritize remediation activities, and can support implementation of recommended controls.
