Plant-Floor Cyber Risk Checklist

A practical self-assessment for manufacturing and industrial organizations

Start the checklist

Use this checklist to identify gaps that could affect production, safety, quality, shipping, or customer confidence. It is designed as a practical readiness tool – not a formal compliance audit or certification.

How to complete the checklist
- Mark one response for each statement: Yes, Partial, No, or N/A.
- Use the notes column to record evidence, system names, owners, or follow-up questions.
- At the end, calculate your readiness score and identify the three highest-priority actions.
