Assess policy strength, evidence maturity, and control coverage. Identify weak areas fast. Build audit confidence with measurable improvement actions.
| Organization | Context Score | Risk Score | Training % | Docs % | Major Findings | Readiness % | Status |
|---|---|---|---|---|---|---|---|
| Northwind Cloud | 4.0 | 4.2 | 92 | 88 | 0 | 87.40 | Certification Ready |
| Blue River Tech | 3.2 | 3.5 | 76 | 70 | 1 | 71.85 | Nearly Ready |
| Atlas Payments | 2.4 | 2.8 | 58 | 54 | 2 | 49.90 | Early Stage |
Weighted Domain Score = sum of each control domain percentage multiplied by its assigned weight.
Domain Percentage = (domain score ÷ 5) × 100.
Operational Evidence Score = training coverage × 0.22 + control testing × 0.22 + documentation completion × 0.28 + risk treatment progress × 0.28.
Governance Bonus = approved scope + statement of applicability + legal register + document control + management review + security KPIs.
Finding Penalty = major findings × 4.0 + minor findings × 0.8.
Complexity Penalty = extra sites × 1.5 plus a modest increase for larger in-scope teams.
Final Readiness Score = (weighted domain score × 0.70) + (operational evidence score × 0.20) + governance bonus − finding penalty − complexity penalty.
The model emphasizes control maturity, implementation evidence, and unresolved audit issues. Scores near 85% suggest stronger readiness for certification planning.
It estimates how prepared your information security management system is for ISO 27001 certification. It combines control maturity, evidence completeness, governance practices, and unresolved findings.
No. The score is a planning indicator, not a formal audit decision. Certification still depends on auditor review, scope accuracy, objective evidence, and effective implementation.
Some areas drive audit success more strongly, especially governance, risk assessment, and access control. Weighted scoring highlights domains that often create broader compliance consequences.
Use 0 for absent, 1 for informal, 2 for basic, 3 for defined, 4 for consistently managed, and 5 for optimized with evidence and review.
Major findings are serious control or governance failures. Minor findings are smaller weaknesses or evidence issues. The calculator penalizes majors more strongly because they threaten certification readiness.
Yes. Smaller teams can use it to benchmark maturity, prioritize corrective work, and track progress over time. Complexity adjustments simply reflect broader coordination effort in larger scopes.
Run it monthly during implementation, before internal audits, after corrective actions, and before the certification audit. Repeating the assessment helps confirm measurable improvement.
A practical target is 85% or higher with no open major findings. Strong documentation, completed reviews, tested controls, and clear evidence are equally important.
