Cyber Essentials is a cyber security scheme which provides organsiations with a framework of fundamental technical security controls which will protect against common cyber attacks.  The Scheme, which is backed by the UK Government and owned by the National Cyber Security Centre (NCSC), focuses on the implementation of 5 key technical control themes: firewalls, patch management, access control, malware prevention, and secure configuration.  When implemented effectively, these controls safeguard against 80% of the most common cyber attacks.  The Scheme offers two levels of certification – Cyber Essentials (CE), and Cyber Essentials Plus (CE+).
