In this article we lay bare the top 10 ISO 27001 companies and the top 10 ISO 27001 certification bodies with guidance you must know before you engage with either and go for ISO 27001 certification. I am Stuart Barker the ISO 27001 Ninja and this is the ISO 27001 top 10 ISO 27001 companies.

How to find an ISO 27001 company

We found this one of the hardest aspects of engaging an ISO 27001 company. Actually finding one.

Using Google, we found we were presented with those companies that had the most budget to spend on ads. This is a competitive market and a lucrative market. Dominating the Google ads comes with advantages for the ISO 27001 company but for the consumer we find that can translate into higher prices.

What to look out for in an ISO 27001 company

This will depend a lot on what your requirements are.

It is our experience that the market is wide from sole traders all the way through the ISO 27001 factories and body shops. Each has its place. Working out what is right for you is the key.

It is our experience that being able to meet the ISO 27001 consultant that will do the work is a great step. It builds the relationship and the trust and can lead to a smoother overall engagement.

UK ISO 27001 Companies

It may not be necessary to go with a UK ISO 27001 company if you find a company that meets your needs. Often the work is done remotely and as such the actual location of the ISO 27001 company has less relevance.

What to be wary of

The thing we recommend being wary of is the shared resource model.

Many of the ISO 27001 companies and ISO 27001 certification bodies use the same independent ISO 27001 consultants.

This pool of ISO 27001 consultants work freelance and make their money working for the many companies that are out there. What this translates to is getting the same resources but only the price differs depending on how you engage them.

This may or may not be important to you. If it is, then ask the question, do you employ third party contractors or do you use your own company employed staff.

Clearly we are an ISO 27001 company. Our list cannot be truly independent but we want you to have choice. Being on the list does not constitute an endorsement by High Table or come with any guarantees or warranties.

Do your own ISO 27001 company due diligence before engaging any company.

Now it’s time for the top 10 ISO 27001 companies updated for 2023 with the latest list of ISO 27001 Consultants and Consultancies and our pick for best ISO 27001 company 2023.

Their billing is not transparent, they take payments and fees up to 9 months in advance of providing a service and will remove your certificate if you do not sign up and pay them for a full recert audit up to 11 months before your certificate expires. Read the small print and the terms and conditions in the contract VERY CAREFULLY. Buyer beware.

A Tough List To Create

I am not going to lie to you. This was a really hard list to come up with. I never thought it would this hard.

The majority of ISO 27001 companies in the UK and worldwide are either one man bands with no website or small early boutique ISO 27001 consultancies with absolutely shocking websites that tell you nothing about what they are going to do for you for ISO 27001.

I think that is why no one has ever created a top 10 list of ISO 27001 companies before.

If you can recommend a decent company I am more than open to changing the list. Just contact me.
