There are two levels of certification:-
Cyber Essentials
This is a self-assessment option which gives you protection against a wide variety of the most common cyber attacks. This is important because vulnerability to simple attacks can highlight you as target for more in-depth unwanted attention from cyber criminals and others.
Certification gives you peace of mind that your defences will protect against the vast majority of common cyber attacks. This is simply because these attacks are looking for targets which do not have the Cyber Essentials technical controls in place.
Cyber Essentials shows you how to address those basics and prevent the most common attacks. CTO can provide insightful consultancy and complete the questionnaire on behalf of the customer, plus oversee the annual certification/re-certification fee process.
Cyber Essentials Plus
Cyber Essentials Plus still has the Cyber Essentials simplicity of approach, and the protections you need to put in place are the same, but for Cyber Essentials Plus CTO also provides a hands-on technical verification of your systems.
