Certification & Governance: Cyber Essentials, Cyber Essentials+ and ISO 27001 

Certification as a Foundation of Trust 

Cyber certifications have shifted from being a “nice to have” to a commercial necessity. Today, 81% of UK organisations report that certification is a requirement for winning new customers. Insurers increasingly demand validated controls such as Cyber Essentials Plus or ISO 27001, and boards now view certification not as paperwork but as a critical element of risk governance. Certification demonstrates credible, independent verification of your security practices. 

The Assurance Hierarchy 

The level of assurance provided varies significantly between standards: 

Certification	Level of Assurance	Primary Purpose
Cyber Essentials (CE)	Self-assessed	Baseline cyber hygiene
Cyber Essentials Plus (CE+)	Independently audited	Validated technical controls
ISO 27001 (ISMS)	Accredited certification	Governance & risk management

Cyber Essentials (CE): The Starting Point 

Cyber Essentials is a UK government-backed scheme defining the minimum controls required to protect an organisation from the most common cyber attacks. The five core controls include Firewalls & Internet Gateways, Secure Configuration, User Access Control, Malware Protection, and Security Update Management. CE is often required for many UK public sector contracts and demonstrates basic cyber competency. Its key limitation is that it is self-assessment only and does not validate effectiveness. CE should be viewed as the starting point, not the destination. 

Cyber Essentials Plus (CE+): Independent Validation 

CE+ includes all CE requirements, plus a technical audit performed by an accredited assessor. This moves organisations from simply believing they are secure to having evidence they are secure. The audit tests real-world effectiveness, including device builds, patch levels, malware defences, and perimeter/internal vulnerability scanning. CE+ is rapidly becoming the new baseline, viewed as the minimum for high-risk suppliers and often required for many regulated tenders. Typical challenges often relate to inconsistent endpoint controls across fleets or patch levels being out of tolerance. 

ISO 27001: The Strategic Management System 

ISO 27001 defines the structure for building an Information Security Management System (ISMS). It is far more than a control list; it is a governance framework covering people, processes, technology, suppliers, and culture. Certification demands leadership commitment, risk assessment and treatment, measurable controls, internal audit, and continuous improvement. ISO 27001 certification provides global recognition, making it the preferred standard for regulated industries and high-assurance supply chains. 

Key Differences: Scope, Assurance, and Maturity 

The differences between these standards define their strategic role: 

• Assurance: CE is self-declared; CE+ is independently tested; ISO is a fully audited management system. 
• Scope: CE/CE+ focus on technical controls; ISO covers the entire organisation (people, process, technology, suppliers). 
• Maturity: CE is baseline, CE+ is intermediate, and ISO is strategic. 

The Incremental Roadmap 

Organisations often benefit from an incremental, staged approach to security maturity: 

• Stage 1: CE Baseline – Focus on technical fundamentals such as patch management uplift, secure configuration, and malware defences. 
• Stage 2: CE+ Assurance – Focus shifts to verification and evidence, ensuring endpoint consistency, build standards verification, and real-world testing. 
• Stage 3: ISO 27001 Governance – The final stage focuses on establishing the ISMS design, formal risk management, supplier oversight, internal audit and KPIs, and continuous improvement.
