What is the difference between ISO 27001 and Cyber Essentials? We are frequently asked this question by existing and potential customers, along with, if I have one, do I need the other? So how do we answer?
It very much depends on why you are looking for certification in the first place, and what risks to your business are you looking to mitigate by being certified.
Both certifications have merit in their own right and also co-exist very nicely together. But fundamentally, they are very different. Think of Cyber Essentials as having an MOT done on your car – there are a list of criteria that you must comply with to gain certification. ISO 27001 is a little different. More like when you go to buy a new car; there are certain things the car must have, (such as lights, brakes and a steering wheel) and then there are options that you get to choose which you have (heated seats, sunroof, colour etc).
Below we describe some of the main features of each.
Cyber Essentials
Cyber Essentials is a government backed certification scheme offering two levels of certification which protect your business against the most common types of Cyber Attacks. It focuses on 5 technical mandatory controls. Cyber Essentials is a verified self-assessment certification that demonstrates an organisation has the required cyber security controls in place. Cyber Essentials Plus is based on the same technical requirements as Cyber Essentials, but it also includes a technical audit of your IT systems to verify the controls are in place. This gives a higher level of assurance that an organisation has correctly implemented the controls.
This scheme was designed to be affordable for small and medium businesses.
Benefits of Cyber Essentials Certification
- It is an affordable scheme to help small and medium businesses implement essential controls.
- Cyber Essentials is actively used as part of supply chain assurance to demonstrate basic cyber hygiene.
- Cyber Essentials certification includes automatic cyber liability insurance for any UK organisation who certifies their whole organisation and has less than £20m annual turnover.
- Cyber Essentials provides an extra layer of defence to organisations even when they have other schemes and standards such as ISO 27001 in place.
ISO 27001:2022
ISO 27001 is an international standard that takes a risk-based approach to implementing an information security management system. Unlike Cyber Essentials it applies across people, process and technology. It consists of mandatory management clauses and is supported by 93 optional controls. These controls do not all have to be implemented, and their selection will be determined and driven by risk assessments.
ISO 27001 can be implemented into organisations of any size, ranging from micro businesses to global enterprises. The standard is flexible to allow for the controls to be applied in a way that is relevant to your business.
Certification is carried out in 2 stages: Stage 1 ensures you have all the necessary requirements and documents in place and Stage 2 is an in-depth audit carried out by a UKAS approved certification body. Certification is valid for 3 years with annual surveillance visits to evidence ongoing compliance to the standard.
Benefits of ISO 27001 certification
- It reduces cost to the business: taking a risk-based approach means only the appropriate controls are put in place
- It enables security to be embedded across an organisation’s people, processes, and technology
- It provides a centrally managed framework to identify and manage information security risk
- It promotes continual monitoring and improvement. As your business matures, so does your Information Security Management System
Summary
So, in conclusion, Cyber Essentials and ISO 27001 are very different certifications with different benefits. But it should be noted, having one or both certifications does not guarantee that you are secure. It means that you have implemented a set of controls that form a part of your security program. Both help you to manage your security practices and to embed robust processes within your business, and to assist with managing the overall risks that you face on a daily basis.
