How to Run a CSF 2.0 Gap Assessment in 30 Days

A structured CSF 2.0 gap assessment is the fastest way to understand your current cybersecurity posture. In just 30 days, manufacturers can baseline their OT security maturity and prioritize investments for compliance and risk reduction.

Week 1: Scope and Inventory

• Define boundaries — which plants, lines, or systems are in scope.
• Compile asset and network inventories using passive tools.
• Map each to CSF 2.0 Identify and Protect categories.

Week 2: Interview and Evidence

Meet with stakeholders (IT, OT, maintenance). Collect documentation: policies, procedures, incident logs, and vendor contracts. Classify controls as Implemented, Partial, or Missing.

Week 3: Score and Analyze

Rate maturity levels (0–5) across CSF functions. Visualize results in a radar chart showing strengths and weaknesses — e.g., Detect = 2.5, Respond = 1.8, Govern = 3.2.

Week 4: Prioritize and Report

• Create an action plan with timelines and responsible owners.
• Highlight quick wins (MFA rollout, network segmentation review).
• Align findings with NIS2 or IEC 62443 where applicable.

Case Example: Electronics Plant

In 30 days, an electronics manufacturer completed a CSF 2.0 gap assessment across two sites. Using the results, they secured a 2025 budget for IDS deployment and Zero Trust pilot zones.
