I am Stuart Barker the ISO27001 Ninja and this is the ISO27001 Supplier Register.
What is a supplier register?
The supplier register is a list of all of the suppliers that we have that store, process or transmit data.
For suppliers we are looking to seek a level of assurance they are doing the right thing for information security.
The easiest way to achieve this is to check that we have an up to date and in date:
- contract that includes clauses for information security and data protection.
- industry level certification that covers the products and / or services we are buying such as an ISO27001 certification can provide us with adequate assurance.
The contract and the industry certification is noted and recorded in the supplier register.
We also record what they do for us and how reliant upon them we are.
The supplier register captures key information about the supplier and is used to manage the supplier reviews and supplier assurance processes.
This will lead to how we manage them.
We will know
- Who our suppliers are
- What the do for us
- If we have a contract
- If they have information security certificates
- What data we share with them
- When we last reviewed them and when we will next review them
Securing the supply chain
Suppliers represent the biggest risk to our organisation in terms of information security.
Suppliers provide us with valuable products, services and resources but they are outside of our control.
We trust them with our most valuable information. We trust them to do the right thing. We trust them with our customers and clients information.
We can protect what we control. We do not control our suppliers.
This is where effective third party supplier management comes in.
The Third Party Supplier Policy sets our how we manage the risk associated with our suppliers.
The Third Party Supplier Register is the tool we use to actively manage them.
Third Party Supplier Assurance
The level of assurance we require is based on risk.
Risk is determined by a number of factors including how critical they are to our operation and how much confidence we can evidence that they are doing the right thing for information security.
It may be we add them to the risk register and manage them via risk management.
As part of our assurance we make sure that every supplier in the register should be reviewed at least annually.
We cover how the supplier fits into the information security management system in the ISO27001 Templates Documents Ultimate Guide.

ISO27001 requirements for an ISO27001 Supplier Register
ISO 27001 has a requirement that you have effectively manage your third party suppliers and ensure the security of the supply chain. The ISO 27001 standard includes an annex called Annex A. Annex A is also a standard in its own right called ISO 27002. ISO 27001 Annex A/ ISO 27002 is a list of ISO 27001 controls that the organisation must implement and supplier management is one of those. The ISO 27001 Annex A / ISO 27002 changed in 2022. Here is what ISO 27002 has to say about supplier management and the supplier register.
ISO27002 Clause 5.19 Information Security In Supplier Relationships
Processes and procedures should be defined and implemented to manage the information security risks associated with the use of supplier’s products or services.
ISO27002 Clause 5.19 Information Security In Supplier Relationships
Here the role of the ISO 27001 supplier register is to identify and record the risks associated with the supplier. It captures a risk score that is used as part of risk management.
ISO27002 Clause 5.20 Addressing Information Security in Supplier Agreements
Relevant information security requirements should be established and agreed with each supplier based on the type of supplier relationship.
ISO27002 Clause 5.20 Addressing Information Security in Supplier Agreements
In the ISO 27001 supplier register we record whether we have a contract that covers the products or services that we are buying. To implement this we would also have a local copy of the contract that we could get access to and we would check that the contract the contract includes information security requirements. We always want to have an in date contract that meets the requirements of this clause before we go for ISO 27001 certification audit.
ISO27002 Clause 5.21 Managing Information Security in the ICT Supply Chain
Processes and procedures should be defined and implemented to manage the information security risks associated with the ICT products and services supply chain.
ISO27002 Clause 5.21 Managing Information Security in the ICT Supply Chain
To apply to processes and procedures we need list of the suppliers.
ISO27002 Clause 5.22 Monitoring, review and change management of supplier services
The organization should regularly monitor, review, evaluate and manage change in supplier information security practices and service delivery.
ISO27002 Clause 5.22 Monitoring, review and change management of supplier services
There are many types of review that can be performed on our suppliers. As a minimum our review would include that we have a relevant, in date contract with appropriate clauses and that we have insurance for information security practices which usually means we have an in date copy of an appropriate information security certificate, such as an ISO 27001 certificate, that covers the products or services that we have bought. These reviews are captured and recorded in the ISO 27001 supplier register.
