Industry maturity scores, tier definitions, and improvement trajectories from 2,100+ ISO 27001 programmes
ISO 27001 Maturity by Industry
2026 cross-industry maturity scores with year-on-year change and tier classification.
| Industry | Maturity | Tier | YoY | Context |
|---|---|---|---|---|
| FinTech | 72/100 | Advanced | +3 | Risk-native culture, automated ISMS operations |
| SaaS | 70/100 | Advanced | +4 | Fastest improver — GRC platform adoption |
| Financial Services | 68/100 | Advanced | +2 | Strong governance, regulatory pressure driver |
| Healthcare | 62/100 | Developing | +2 | Improving — HIPAA alignment creating uplift |
| eCommerce | 61/100 | Developing | +3 | Growing awareness post-data breach incidents |
| Retail | 55/100 | Developing | +1 | Stagnant — resource constraints, low prioritisation |
| Hospitality | 49/100 | Foundational | +1 | Below average — distributed estate challenges |
Maturity Tier Definitions
ISMS is fully operationalised. Risk treatment is systematic and evidence-driven. Continuous improvement is embedded in management cadence. Automation rate >55%.
ISMS is implemented and operational but not fully embedded. Evidence quality is inconsistent. Risk assessments conducted but not always acted upon systematically. Automation rate 30–55%.
ISMS exists on paper but operationalisation is incomplete. Control evidence is sparse or outdated. Risk assessments are infrequent. Automation rate <30%.
ISO 27001 vs PCI DSS — Maturity Comparison
ISO 27001 programmes average 4 points higher maturity than PCI DSS across industries. The risk-based scoping of ISO 27001 allows organisations to concentrate resources on areas of highest risk, whereas PCI DSS requires uniform compliance across all 12 requirements regardless of risk context.
Improvement Trajectories
Year-on-year maturity gains vary significantly by industry and automation adoption level.
GRC platform adoption + cloud-native ISMS automation driving rapid uplift
Sustained investment in risk management and regulatory alignment
Resource constraints and low prioritisation limiting progress
Frequently Asked Questions
What is the average ISO 27001 maturity score?
62/100 is the cross-industry average ISO 27001 maturity score in 2026. FinTech leads at 72/100 and Hospitality is lowest at 49/100. Maturity is scored across ISMS operationalisation, risk treatment effectiveness, control evidence quality, and continuous improvement cadence.
What does the ISO 27001 maturity score measure?
ISO 27001 maturity (0–100) measures four dimensions: (1) ISMS operationalisation — how embedded the management system is in daily operations; (2) Risk treatment effectiveness — quality of risk assessments and treatment decisions; (3) Control evidence quality — completeness and currency of Annex A control evidence; (4) Continuous improvement — frequency and rigour of management reviews and corrective actions.
How does ISO 27001 maturity compare to PCI DSS maturity?
ISO 27001 averages 62/100 vs PCI DSS 58/100 cross-industry. ISO 27001 tends to score higher because its risk-based approach allows organisations to tailor the control scope, whereas PCI DSS's prescriptive 12-requirement structure leaves less flexibility and surfaces more compliance gaps.
