NIST CSF Mapper

Map your organization's current security controls and tooling to the NIST Cybersecurity Framework (CSF) 2.0. Provide your company profile, existing security tools, and control posture — get back a function-by-function CSF coverage report, gap analysis, maturity tier rating, and a prioritized improvement roadmap across all six CSF functions: Govern, Identify, Protect, Detect, Respond, and Recover.

Company Profile

Control Posture (boolean flags)

What You Get

• CSF function-by-function coverage — maturity score across Govern, Identify, Protect, Detect, Respond, Recover
• NIST CSF Tier rating — overall tier assessment (Tier 1 Partial → Tier 4 Adaptive)
• Subcategory gap map — which specific CSF subcategories (e.g., ID.AM-1, PR.AC-3) are covered, partial, or missing
• Tool-to-CSF mapping — how your existing tools map to CSF functions and subcategories
• Regulatory crosswalk — how CSF gaps align to your stated compliance requirements
• Prioritized improvement roadmap — Quick Wins (0–30 days), Short-term (30–90 days), Strategic (90+ days)
• Executive summary — board-ready posture summary with tier rating and top risks
