Cyberattacks pose a significant threat to businesses, causing disruption ranging from financial losses to reputational damage and operational downtime. The increasing sophistication of cyber threats means organisations of all sizes must proactively safeguard their data, systems, and networks. Implementing robust cybersecurity measures is no longer optional—it’s a critical business priority.
Two widely recognised frameworks that help businesses manage cyber risks are Cyber Essentials and ISO 27001. The UK Government initiative Cyber Essentials provides essential protection against common threats, focusing on five technical controls. Meanwhile, ISO 27001 offers a comprehensive, internationally recognised standard for an information security management system containing up to 93 controls across technological, physical, organisational, and personnel aspects to provide a holistic approach.
Let’s take a look at the organisational fit of these two frameworks:
| Organisation | Cyber Essentials | ISO 27001 |
| Small and Medium (SME) | It is ideal for providing a foundational level of protection without a heavy investment in time and resources. | This may be a challenge due to the complexity and costs of certification. However, if a regulated industry is supplied, it may be a mandatory requirement. It is also recommended for businesses going through mergers and acquisitions (M&A) |
| Large Organisations and Enterprises | It is suitable for basic device security but has limited effectiveness in more complex environments, as it doesn’t cover advanced controls. | Provide a robust risk-based information management and security system that includes staff awareness, |
| Regulated Industries (Finance, Health, Infrastructure) | It is suitable only as a baseline and will need supplementing with other standards or frameworks. | Often mandated requirements and provides internationally recognised standards. |
Both standards offer certification to demonstrate a company’s attainment.
| Certification | Cyber Essentials | ISO27001 |
| Basic | A self-assessment questionnaire (SAQ). | Requires a full information management system (ISMS) implementation and independent audit |
| Enhanced | This Cyber Essentials Plus requires an independent assessor to perform an additional technical audit in addition to the SAQ. | There is no tiered level, but continuous improvement is required through regular internal audits. |
| Validity | Annual re-certification and looks for continuous improvement | Three-year certification cycle with periodic surveillance audits for constant compliance. |
