OThello Assess ingests your documentation, extracts evidence, and involves your team only where it counts (assets, crown jewels, key decisions). Everything else is automated. Audit-ready in hours.

Every assessment has the same structural problems. OThello fixes all three.
It takes weeks, not days.
Traditional risk assessments are inherently inefficient. Manual evidence gathering. Documentation scattered across systems and teams.
Evidence lives everywhere.
Asset inventories, network diagrams, config files spread across formats and ownership. Nobody has the full picture in one place.
Results aren't comparable.
Different interpretations of the same framework produce different scores. OThello applies the same methodology every time so you can track genuine improvement, not methodology variance.
Five steps. Under 24 hours. Your judgement built in.
Three of the five steps are yours. They take about 45 minutes in total. The rest is OneIQ.

~45 min total human input
01
Upload documentation.
Your network architecture, asset inventory, zone diagrams. OThello provides a clear input guide you collect what already exists in your environment. OneIQ begins extracting and structuring immediately.
02
Review the analysis and refine your assets.
OneIQ presents the assets it identified from your documentation. Review the analysis, confirm what's correct, add any missing assets, and edit details where needed. This step takes about 15 minutes and ensures the assessment reflects your actual environment.
03
Review and refine your crown jewels.
OneIQ suggests crown jewels based on your environment. Review the list, add critical assets that were missed, or remove items that don't represent your highest operational risks. This takes about 10 minutes and calibrates the analysis to what matters most.
04
Answer 10–20 targeted questions.
OneIQ generates a short set of questions based on what it found and what it couldn't determine from your documentation. These are not a generic IEC 62443 checklist. They are specific to your environment, filling the evidence gaps that documentation alone cannot close. Takes about 20 minutes.
05
Receive your audit-ready output.
OneIQ runs the full FR and SR analysis against your enriched environment model. Risk score, evidence-cited gap analysis, prioritised remediation roadmap. Every finding traceable to a source. Repeat the cycle after remediation to validate improvements and show the delta.

Run your first assessment
Everything you need for an OT risk assessment. Built around how your team actually works.
Assessment in under 24 hours.
A full IEC 62443 assessment cycle from documentation upload to compliance report.
Multi-standard coverage.
IEC 62443, NIS2, NERC CIP, OTCC, CENELEC TS 50701. One assessment run.
Consistent results, every time.
Same methodology. Same framework interpretation. Comparable results across every site, every cycle, every analyst. When your score improves, you know it reflects a genuine change
Audit-ready output.
Reports structured to meet compliance deadlines and satisfy auditors. Evidence cited against source documents. Every finding is traceable.
Evidence extracted, not declared.
OneIQ extracts evidence from your existing documentation automatically. The score reflects what actually exists in your environment
You stay in control.
The platform handles evidence extraction, framework mapping, and threat inference. You define priorities, validate findings, and make decisions.
Your first assessment is the start. Not the end.
Run the cycle again after remediation. Compare your new score against the baseline. Track improvement over time with consistent methodology.
Reassess after remediation.
Once you've addressed the gaps identified in your baseline assessment, run OThello Assess again. Same methodology, same framework, same OneIQ analysis
Track drift between cycles.
Environments change. New assets appear. Configurations drift. OThello tracks these changes across assessment cycles, highlighting what improved, what regressed, and what stayed constant.

Documented. Defensible. Auditable.
Continuous improvement, not periodic compliance.
Treat security posture as an ongoing program, not a checkbox exercise. Every reassessment builds on the last.
Multi-site drift tracking.
Run the same assessment across multiple sites. Compare their baselines, track their improvement independently, and identify where drift is happening.
OneIQ doesn't give you a template. It gives you your assessment.
Most assessment tools generate a templatized and generic output from a fixed questionnaire. OneIQ doesn't. It builds a working model of your specific environment including zone topology, crown jewels, documented controls and runs the IEC 62443 analysis against that model.
Every finding is cited. Every recommendation is contextual. Every score is evidence-based. Your auditor can trace the reasoning from source documents
Data stays in your jurisdiction.
On-premise deployment available, air-gapped environments supported and the assessment data never leaves your infrastructure. Cloud-hosted option available.
Proof an auditor can trust.
Every gap identified in your report includes the source evidence, the framework requirement it maps to, and the reasoning OneIQ applied.
Built for the teams responsible for getting assessments right.
OT Security Teams
Upload documentation, confirm assets, define crown jewels, answer targeted questions. The platform handles framework mapping, evidence extraction, and threat analysis. You contribute the judgement that only you team can provide
Compliance Leaders
Generate IEC 62443 evidence in under 24 hours. Every finding cited against source documents. The methodology is consistent across sites and cycles so you can track real improvement, not assessment variance. Your next audit starts with a complete evidence package already assembled.
Industrial Risk Programs
Measure security posture across multiple sites with the same methodology. Track improvement over time. Show leadership that the program is working with data, not anecdotes. OThello turns compliance into a strategic capability, not a cost center.

OneIQ suggests crown jewels based on your environment. Review the list, add critical assets that were missed, or remove items that don't represent your highest operational risks. A DCS controller in a safety-critical loop is not the same risk as a historian server. Only you know which is which. This takes about 10 minutes and calibrates the analysis to what matters most.
