Cyber Essentials Certification
Origin
Cyber Essentials was created by the UK Government in 2014 in collaboration with industry experts and the National Cyber Security Centre (NCSC). The scheme was developed in response to the growing threat of cybercrime and the recognition that many cyber attacks could be prevented through basic security controls. It was designed to help organizations of all sizes protect themselves against common internet-based threats and establish a baseline of cybersecurity hygiene.
Industry Value and Importance
Cyber Essentials is highly valued in both public and private sectors as it demonstrates an organization's commitment to cybersecurity. UK government contracts involving handling of sensitive and personal information require Cyber Essentials certification as a mandatory prerequisite. Beyond compliance, the certification helps organizations reduce their vulnerability to approximately 80% of common cyber attacks, provides insurance benefits with some providers offering premium reductions, and serves as a trust signal to customers and partners. Many businesses also require their suppliers to hold the certification as part of their supply chain security requirements, making it increasingly important for maintaining competitive advantage in the marketplace.
