Your customer asks for a NIS2 Supply Chain certificate. Now what?

Short answer

The NIS2 Supply Chain certificate is a voluntary quality mark for suppliers to organisations in scope of NIS2. It has three levels: SC10, SC20 and SC30. The law does not prescribe a certificate. Your customer can ask you to demonstrate that you operate securely, and decide for itself whether it requires a certificate for that. So first ask what your customer actually expects: the certificate, or answers with evidence.

A customer in scope of the Dutch Cybersecurity Act can ask you to demonstrate that you operate securely. Sometimes it mentions the NIS2 Supply Chain certificate. This is what it is, and what you can do if you do not have it (yet).

What the certificate is

The NIS2 Supply Chain certificate was developed by the Dutch Stichting Kwaliteitsinnovatie (Kiwa, NIS2 Supply Chain, in Dutch). It was launched in October 2024 as the NIS2 Quality Mark, with the levels QM10, QM20 and QM30 (Accountancy van Morgen, 11 October 2024, in Dutch). The levels are now called SC10, SC20 and SC30. It is a quality mark, not a law.

The scheme’s website describes the levels as follows (NIS2 Supply Chain, FAQ):

LevelFor whom
SC10SMEs with a limited risk that supply organisations in scope of NIS2
SC20Companies with an elevated risk because of their role or their access to sensitive data
SC30Critical companies in the supply chain, where a disruption can have major consequences

Is it mandatory?

Not under the law. Organisations in scope of NIS2 must manage the security of their supply chain. That is why they can require their direct suppliers to demonstrate that they operate securely (NIS2 Supply Chain, FAQ). The Dutch NCSC writes that certificates can help, but that the Cybersecurity Act does not prescribe them (NCSC, Suppliers of Cbw organisations, in Dutch). So whether you need a certificate is up to your customer, for example in a tender or in the contract. More on what a customer in scope can ask of you: Dutch Cybersecurity Act: what can your customer require of you?

How to obtain the certificate

According to the scheme’s website it takes five steps (NIS2 Supply Chain, for companies):

  1. You pre-register your organisation.
  2. You prepare for the audit: documentation and measures in order.
  3. You attend a pre-audit webinar. This is mandatory if you want to obtain the certificate.
  4. An independent, recognised auditor of your choice carries out the certification audit.
  5. After a positive assessment you receive the certificate.

For SC20 and SC30 the auditor must have knowledge of ISO 27001 (FAQ). One of the certification bodies mentions a three-year certification cycle for SC20 and SC30 (Kiwa, in Dutch). Check the current conditions and costs with the auditor you choose.

First ask what your customer really wants

What you can provide now

If you do not have a certificate (yet), you can still show which measures you have. This evidence fits the topics a customer may ask about:

TopicWhat your customer wants to knowEvidence you can show
Policy and risksHave you mapped your security and your risks?Information security policy, risk assessment, overview of measures
AccessWho can access what, and is MFA on?MFA settings, overview of access rights, joiner and leaver procedure
UpdatesHow quickly do you install security updates?Patch policy, overview of recent updates
Back-ups and recoveryCan you restore your data?Back-up policy, report of the latest restore test
IncidentsHow do you report and contain an incident?Incident procedure, contacts, notification times
Your own suppliersWho else works on the service for you?List of suppliers and sub-processors, their certificates or reports
AwarenessDo your staff know what to do?Overview of trainings and who attended

How strong each kind of evidence is, you can see on the evidence ladder. Be honest about what is not there yet. For example: “We do not have a NIS2 Supply Chain certificate. Our measures are described in document X; the September restore test is in report Y.”

Frequently asked questions

Is the NIS2 Supply Chain certificate mandatory?

Not under the law. The Dutch Cybersecurity Act does not prescribe a certificate. Your customer can require it, for example in a tender or the contract.

Which level do I need?

That depends on your role in the supply chain and on what your customer asks. According to the scheme's website, SC10 is for SMEs with a limited risk and SC20 for companies with an elevated risk, for example because of access to sensitive data. Ask your customer which level it expects.

Is this the same as ISO 27001?

No. ISO 27001 is an international standard for an information security management system. The NIS2 Supply Chain certificate is a quality mark with levels for suppliers in the NIS2 supply chain. Ask your customer whether it also accepts ISO 27001.

Was this previously the NIS2 Quality Mark?

Yes. The mark was launched in October 2024 as the NIS2 Quality Mark, with the levels QM10, QM20 and QM30. They are now called SC10, SC20 and SC30.
