OT and Industrial Control System (ICS) Risk Assessment

Risk-focused assessment of OT and ICS environments to identify exposure, safety impact, and resilience gaps without disrupting production.

OT and ICS environments are constrained by uptime, safety, and operational reality. That makes many conventional security approaches impractical, and it is also why risk can accumulate quietly as networks converge, remote access expands, and vendor dependencies grow. This assessment is a structured review of OT assets, dependencies, and attack surface, focused on realistic paths that could impact availability, safety, or production. The objective is not to disrupt operations or perform invasive testing. It is to translate cyber exposure into operational risk and decision-relevant evidence.

When it’s a fit

  • You have OT environments with increasing connectivity to IT, vendors, or remote access
  • Leadership needs a clear view of operational and safety impact, not just technical findings
  • You need risk visibility that does not disrupt production or introduce safety concerns
  • Ownership is fragmented across IT, engineering, and operations, and accountability is unclear
  • A customer, insurer, or regulator is driving requirements, but scope is uncertain

What you get

  • Asset- and process-aware risk assessment tailored to OT and ICS realities
  • Identification of realistic attack paths that could impact availability, safety, or production
  • Clear differentiation between unacceptable risk, tolerable exposure, and compensating controls
  • Findings framed for both technical teams and operational leadership
  • Practical mitigation options that respect uptime and safety constraints
Discuss scope and approach

Most clients start with partial visibility and mixed ownership across operations, engineering, and IT. We help define a scope that respects production constraints while still surfacing the risks that matter.

We’ll propose an appropriate assessment approach, outline scope options, and provide a pricing range based on environment complexity and depth.

Pricing is project-based and defined by environment complexity and assessment depth.

What determines the scope of an assessment
  • Environment focus: sites, process areas, critical assets, remote access paths, and dependencies
  • Depth: asset and dependency mapping, architecture and segmentation review, and focused risk areas tied to safety and uptime

How this fits into the bigger picture

OT and ICS risk assessments provide decision-ready assurance inputs without disrupting production environments. They help align IT, engineering, and operations around a shared view of exposure and operational impact, and they surface where current controls and ownership do not match the organization’s tolerance for disruption or safety risk.

For audit readiness and evidence validation, organizations typically engage Compliance Readiness and Gap Assessment.

OT and ICS risk assessments do not guarantee outcomes. They provide evidence leadership can interpret against risk appetite, safety constraints, and acceptable operational tradeoffs.

Leadership
Clarifies operational risk, safety impact, and resilience priorities.
Operations
Identifies practical risk reduction options that respect uptime and safety.
Assurance
Provides evidence of exposure and attack paths without disruptive testing.
