The Oxford CMM - Global Leaders in Cybersecurity Capacity: 2025–2026 Rankings

The Oxford CMM: A Roadmap for National Digital Resilience

The Oxford Global Cyber Security Capacity Maturity Model (CMM) is a pioneering framework developed by the Global Cyber Security Capacity Centre (GCSCC) at the University of Oxford. It is designed to help nations assess their cybersecurity maturity across a broad spectrum of social, technical, and legal factors.

What is the Oxford CMM Index?

The Oxford CMM is a comprehensive framework used by nations to measure their cybersecurity maturity across five dimensions: Policy & Strategy, Culture & Society, Knowledge & Skills, Legal & Regulatory, and Standards & Tech. Unlike simple technical rankings, it provides a qualitative roadmap for countries to progress from "Start-up" to "Dynamic" levels of cyber resilience.


1. The Five Dimensions of the CMM

The model evaluates a country’s maturity through five "Dimensions," which together represent the holistic ecosystem of national cybersecurity:

DimensionFocus Area
D1: Policy & StrategyNational strategy, incident response (CSIRTs), and critical infrastructure protection.
D2: Culture & SocietyPublic awareness, trust in the internet, and the role of media in cybersecurity.
D3: Knowledge & SkillsEducation, professional training, and the availability of a skilled workforce.
D4: Legal & RegulatoryCybercrime legislation, data protection, and international legal cooperation.
D5: Standards & TechUse of international standards (ISO/IEC), software quality, and technical controls.

2. The Five Stages of Maturity

For each factor within these dimensions, a country is graded on a scale of 1 to 5:

  1. Start-up: No formal processes; capacity is ad-hoc or disorganized.

  2. Formative: Elements of capacity are emerging but lack consistency.

  3. Established: Processes and policies are in place and functioning.

  4. Strategic: Capacity is integrated into national planning and prioritized.

  5. Dynamic: The country can rapidly adapt to changing threats and lead globally.

3. Global Impact and Evolution (2025–2026)

As of early 2026, the CMM has been deployed in over 120 reviews across 85+ countries. The model has evolved significantly to meet modern challenges:

  • AI Cybersecurity Readiness: Recent 2025 updates have integrated AI-specific risks into the framework, helping nations prepare for the dual-edged sword of artificial intelligence.

  • The Global Constellation: Oxford now operates via a "Global Constellation" of research centers, including the Oceania Cyber Security Centre (OCSC) and the Cybersecurity Capacity Centre for Southern Africa (C3SA).

  • Continuous Maturity: In 2026, the trend has shifted from "point-in-time" reviews to continuous monitoring, using automated data collection to update a nation's maturity status.



Global Leaders in Cybersecurity Capacity: 2025–2026 Rankings

While the Oxford CMM is primarily a diagnostic tool rather than a competitive leaderboard, recent data from 2025 and 2026 highlight specific nations that have achieved "Strategic" and "Dynamic" stages across various dimensions. These countries often serve as regional blueprints for cyber resilience.


1. Top Performing Nations by Region

The Global Cyber Security Capacity Centre (GCSCC) has noted that certain countries consistently outperform their peers by integrating cybersecurity into the very fabric of their national governance and economy.

RegionLeading Countries (2025–2026)Key Strengths
EuropeCzechia, Finland, United KingdomHigh institutional coordination and mature legal frameworks (GDPR compliance).
AmericasDominican Republic, JamaicaPioneers in the LAC region for National CSIRTs and updated cybercrime laws.
Asia-PacificSingapore, Australia, South KoreaGlobal leaders in technical standards and public-private sector data sharing.
AfricaMauritius, Ghana, RwandaRapid advancement in D1 (Policy) and D3 (Education/Skills).

2. Why These Countries Excel

Leading nations in the Oxford CMM index share three common characteristics that elevate them toward the Dynamic stage:

  • Integrated Strategies: Countries like Finland and Czechia do not treat cybersecurity as an "IT issue." Instead, they have cross-ministerial strategies that link cyber-defense with national security and economic growth.

  • Active Regional Collaboration: High-performing nations often host or lead regional "Constellations." For example, Australia's OCSC and South Africa's C3SA allow these nations to export their knowledge while staying ahead of regional threat trends.

  • Investment in "Human Capital": The most mature nations prioritize Dimension 3 (Knowledge & Skills). By 2026, leaders like the UK have established nationwide cybersecurity curricula and professional certification standards that ensure a steady pipeline of talent.


3. The "AI Readiness" Shift (2026)

In 2026, the definition of a "leading country" has shifted. Maturity is no longer just about defending against malware; it is about AI Resilience.

2026 Trend: Nations such as Singapore and Germany are currently the only ones approaching "Dynamic" status in the new AI Readiness Metric. They have implemented specific legal frameworks to govern AI-driven threats and automated incident response systems that can counter AI-generated phishing at scale.



Key Performance Indicators (KPIs) and Metrics: How Success is Measured

The Oxford CMM does not rely on a single numerical score. Instead, it measures progress through a hierarchy of Factors, Aspects, and Indicators. For a nation to move from one maturity stage to the next (e.g., from Established to Strategic), it must provide verifiable evidence that it has met specific Indicators—the model’s version of KPIs.


1. Strategic KPIs by Dimension

In the 2021–2026 framework, specific performance indicators serve as the "litmus test" for national capability:

DimensionKey Performance Indicator (Indicator)Evidence of "Strategic" Maturity
D1: PolicyIncident Response CoverageA functional National CSIRT with 24/7 monitoring and cross-border data sharing.
D2: CulturePublic Trust LevelsMeasurable increase in the use of e-government services and multi-factor authentication (MFA) adoption.
D3: KnowledgeWorkforce PipelineDedicated cybersecurity degree programs in 50%+ of national universities.
D4: LegalAdherence to International LawRatification and active enforcement of the Budapest Convention or equivalent regional treaties.
D5: StandardsSupply Chain IntegrityMandatory cybersecurity requirements in public procurement and software development life cycles.

2. The Measurement Hierarchy

To ensure objectivity, the Oxford GCSCC uses a granular assessment structure:

  • Factors: The high-level goals (e.g., Factor 1.1: National Cybersecurity Strategy).

  • Aspects: Sub-themes that break down a factor (e.g., Strategy Content, Development Process, and Implementation).

  • Indicators (The Metrics): These are largely binary. A country either possesses the evidence (e.g., "There is a formal budget allocated for the strategy") or it does not.

  • Evidence Gathering: Unlike self-reported surveys, CMM indicators are validated through stakeholder consultations (often 10+ sessions over 3 days) and desk research performed by Oxford-trained researchers.


3. Emerging 2026 "Dynamic" Indicators

As cyber threats become more sophisticated, the "Dynamic" (Stage 5) indicators have shifted to focus on predictive rather than reactive capabilities:

  • KPI: Automated Threat Hunting: Does the nation use AI-driven systems to proactively identify vulnerabilities in Critical National Infrastructure (CNI)?

  • KPI: Cyber Diplomacy: Does the country lead international norm-setting for responsible state behavior in cyberspace?

  • KPI: Sovereign Redundancy: Can the nation maintain essential services (power, water, finance) during a total internet blackout?


Note on Benchmarking: While the ITU’s Global Cybersecurity Index (GCI) provides a numerical ranking, the Oxford CMM KPIs are designed to create a Cyber Resilience Roadmap. If a country fails a KPI in Dimension 3 (Knowledge), the CMM report provides the specific "Steps to Advance" to reach the next stage.


The Ecosystem of Collaboration: Key Organizations and Partners

The success of the Oxford CMM is built on a "Global Constellation" of academic, governmental, and international organizations. This network ensures that the model is not just a theoretical framework from the UK but a globally applicable tool with local cultural and technical relevance.


1. The Core: Global Cyber Security Capacity Centre (GCSCC)

Based at the Oxford Martin School, University of Oxford, the GCSCC is the central architect of the model. It directs the research, updates the dimensions (such as the 2021 and 2025 AI updates), and maintains the technical standards for all assessments worldwide.

2. The Global Constellation (Regional Hubs)

To decentralize the model and provide regional expertise, Oxford has established a "constellation" of regional centers:

  • Oceania Cyber Security Centre (OCSC): Based in Melbourne, Australia, it leads CMM reviews across the Pacific (e.g., Fiji, Samoa, and Kiribati).

  • Cybersecurity Capacity Centre for Southern Africa (C3SA): Located at the University of Cape Town, this hub focuses on digital inclusion and rights-based cybersecurity maturity across Africa.

  • Monash University (Indonesia/Australia): As of 2025–2026, Monash has deepened its partnership with GCSCC to specifically address AI-driven cybersecurity readiness in the Asia-Pacific region.

3. Strategic and Implementation Partners

Oxford collaborates with heavyweight international organizations to fund and deploy the CMM. These partners often use the CMM results to determine where to provide financial aid or technical assistance:

Organization TypeKey Partners
International BodiesWorld Bank, ITU (International Telecommunication Union), OAS (Organization of American States)
Government AgenciesUK FCDO (Foreign, Commonwealth & Development Office), Norway's MFA, Japan’s JICA
ImplementationGlobal Forum on Cyber Expertise (GFCE), NRD Cyber Security, GIZ (Germany)

4. Knowledge Sharing: The Cybil Portal

One of the most important organizational outputs is Cybil, the Cyber Capacity Knowledge Portal. Developed by the GCSCC and its partners (including the ASPI and DiploFoundation), it serves as a public repository for CMM reports and case studies. This ensures that a country in Europe can learn from the "Strategic" successes of a country in Africa or Asia.

5. Funding and Oversight

The GCSCC is primarily funded by the UK Government (FCDO) and the Government of the Netherlands, with additional project-specific funding from regional partners like the State Government of Victoria (for the OCSC). A Technical Board of senior academics and policy experts oversees the program to maintain its strict objectivity.


Did you know? In 2025, the Japan International Cooperation Agency (JICA) collaborated with Oxford and the Mongolian government to perform one of the most comprehensive CMM reviews to date, involving over 150 stakeholders.


Data Collection Methodology: An Evidence-Based Approach

The Oxford CMM stands apart from other indices because it does not rely on subjective surveys or self-reporting. Instead, it utilizes a rigorous, multi-modal data collection process designed to extract verifiable evidence of a nation’s capacity. In 2026, this process has become even more sophisticated, blending traditional field research with modern digital analysis.


1. Primary Source: Multi-Stakeholder Consultations

The "gold standard" of the CMM is the In-Country Review. This involves intensive focus groups led by Oxford-trained researchers. These sessions are organized into "Stakeholder Clusters" to ensure a 360-degree view of the national landscape:

  • Public Sector: Ministries of Defense, ICT, Justice, and Foreign Affairs.

  • Critical Infrastructure: Operators from energy, finance, health, and transport sectors.

  • Academia & Civil Society: University researchers, NGOs, and digital rights advocates.

  • Criminal Justice: Law enforcement agencies, prosecutors, and the judiciary.

  • Private Sector: ISPs, cybersecurity firms, and trade associations.

2. The "Consensus-Building" Technique

During these consultations, researchers facilitate a discussion rather than just asking questions. The goal is to reach consensus among participants. If a government official claims a policy exists but civil society and the private sector have never seen it implemented, the "Evidence" for that KPI is deemed insufficient, and the country will not advance to the next maturity stage.

3. Secondary Sources and Desk Research

Consultations are preceded and followed by extensive Desk Research to verify claims. Key data sources include:

  • National Gazettes & Legislation: Verifying the legal status of cybercrime laws.

  • Budgetary Documents: Confirming that cybersecurity strategies are actually funded.

  • Technical Audits: Reviewing public reports from National CSIRTs and CERTs.

  • Global Databases: Cross-referencing data with the ITU’s Global Cybersecurity Index, the World Bank, and the United Nations Institute for Disarmament Research (UNIDIR).


4. Modern Data Evolution (2025–2026)

By 2026, the GCSCC has integrated more dynamic data-gathering tools to supplement the traditional five-dimension model:

  • Automated Policy Scanning: Using Natural Language Processing (NLP) to analyze national strategy documents for alignment with international best practices.

  • Digital Footprint Analysis: Incorporating technical data on national IP space security and SSL certificate adoption as secondary indicators for Dimension 5 (Standards & Tech).

  • The "Cybil" Portal: This global database acts as a live repository where countries can upload updated evidence between formal 3-year review cycles, allowing for a "living" maturity score.


The Quality Control Filter: Before a report is finalized, the collected data must pass through a Technical Board Review at the University of Oxford. This ensures that the findings are not only accurate but also free from political bias or local influence.
