8 April 2026 • NIS2
More and more organisations are searching for an NIS2 quality mark: official proof that they meet the requirements of the EU cybersecurity directive. But does such a mark actually exist? And what can you do to make your NIS2 compliance visible to clients, partners, and procurement teams?
Does an official NIS2 quality mark exist?
The short answer is no. There is currently no official NIS2 quality mark or certification scheme.
Unlike ISO 27001, where an accredited third party issues a certificate following an audit, NIS2 has no equivalent certification system. NIS2 is a legal obligation enforced by national supervisory authorities, not a voluntary quality standard for which you can earn a mark.
Competent authorities monitor whether organisations comply with the law and can take enforcement action when they do not. But there is no positive certificate or quality mark you can hand over as proof of compliance.
That does not mean NIS2 compliance says nothing about your organisation. It says quite a lot, and you can use it accordingly.
How to demonstrate NIS2 compliance without a quality mark
Although no official NIS2 quality mark exists, there are several ways to make your compliance tangible:
- Self-assessment and documentation – NIS2 already requires you to document your measures, risk analyses, and policies. That documentation is demonstrable evidence of compliance.
- Internal or external audit – Have an independent party assess whether your measures meet NIS2 requirements and record the findings in an audit report.
- ISO 27001 certification – ISO 27001 has substantial overlap with NIS2 and is certifiable. Organisations that hold ISO 27001 certification have already covered most of the NIS2 foundation.
- Procurement declarations – Communicate actively that your organisation is NIS2-compliant and offer it as documented evidence in tenders and contract negotiations.
NIS2 vs ISO 27001: what is the difference?
Many organisations confuse NIS2 and ISO 27001, or wonder how the two relate to each other. NIS2 is a legal obligation; ISO 27001 is a voluntary international standard. But they complement each other strongly.
| NIS2 | ISO 27001 | |
|---|---|---|
| Type | EU legal directive | International standard (voluntary) |
| Applies to | Designated sectors above size thresholds | Any organisation that chooses to certify |
| Certificate available? | No | Yes, via accredited certification body |
| Enforcement | National supervisors, sanctions possible | No external enforcement |
| Overlap | Significant: risk analysis, access management, incident response, supply chain, awareness training | |
Organisations that already hold ISO 27001 certification have a strong foundation for NIS2, but NIS2 adds specific obligations that ISO 27001 does not automatically cover, such as the 24-hour incident reporting requirement and explicit board-level liability.

NIS2 compliance as a competitive differentiator
Even without an official quality mark, NIS2 compliance is increasingly becoming a distinguishing factor, much like ISO 27001 has been for years. There are four main reasons for this.
Procurement and supply chain requirements
Government bodies and large organisations that are themselves NIS2-obligated must secure their supply chain. As a result, they increasingly impose NIS2-compliant security requirements on their suppliers. Organisations that can demonstrate compliance now have an advantage in tender processes.
Client trust and reputation
A data breach or ransomware attack costs more than money. It costs trust. Organisations that communicate openly about their cybersecurity measures and compliance build a reputation for reliability. This matters especially in sectors where clients entrust sensitive data, such as healthcare, finance, and legal services.
Insurability
Cyber insurers are scrutinising the security posture of organisations more closely before issuing policies. NIS2 compliance, and the documentation that comes with it, can contribute to obtaining better insurance terms.
Internal leadership
NIS2 places responsibility explicitly at board level. Organisations that take compliance seriously drive a culture of awareness and accountability from the boardroom to the shop floor. That benefits more than just security.
How to communicate NIS2 compliance without a quality mark
Since no official mark exists, you need to define how you make compliance visible. Some practical options:
- Add a NIS2 compliance statement to quotes and contracts, referencing your documented policies and audits.
- Publish a concise summary of your security measures on your website. Transparency builds trust.
- Combine NIS2 with ISO 27001 certification for maximum external credibility.
- Reference your NIS2 compliance in tenders as evidence of information security maturity.
There is no official NIS2 quality mark. But that does not make NIS2 compliance less valuable. Organisations that invest now in demonstrable compliance, through solid documentation, staff training, and if relevant ISO 27001 certification alongside it, build a security position that is visible to clients, partners, and regulators alike.
Just as ISO 27001 has become a trust signal over the past decade, NIS2 compliance will increasingly be expected as proof of reliability in the years ahead. The organisations that start now are the ones that will have the edge when that moment arrives.
