What is CyberFundamentals ?

The CyberFundamentals Framework offers a clear, step-by-step approach that helps organisations to protect their data, significantly reduce their risk of the most common cyber-attacks, and their cyber resilience. 

The requirements and guidance are complemented with the relevant insights included in the NIST/CSF framework, ISO 27001/ISO 27002, IEC 62443 and the CIS Critical Security Controls (ETSI TR 103 305-1). 

Built around three maturity levels – Basic, Important, and Essential – CyFun® guides you in growing your digital resilience. Whether you're a small business or a large enterprise, CyFun® provides an accessible roadmap to a safer digital future. Want to know more?
