NSIS Statement | Digital Identity & IT Compliance

NSIS - document your security to authorities and critical partners 

NSIS is the Danish government's framework of requirements for information security. It applies to public authorities and private companies that provide solutions to the state, regions and municipalities - especially in emergency response or critical functions. 

With an auditor's statement on NSIS, you can prove that your company meets the requirements and can be part of critical supply chains. 

What is NSIS? 

NSIS (National Standard for Information Security) is a Danish security standard that sets requirements for IT suppliers and partners to the public sector - especially in relation to emergency response functions, infrastructure and critical systems. 

The standard draws on ISO 27001, but has separate requirements for e.g. supplier management, incident management and access to data. 

When is NSIS relevant? 

  • When you deliver solutions to the public sector - e.g. data processing, operations or platforms 
  • When you are asked to document compliance in procurement 
  • When you are part of supply chains for critical functions 
  • When you want an independent assessment of your security level in relation to NSIS 
  • When your customers request a declaration as part of emergency response or supervision

Frequently asked questions (FAQ) 

Is NSIS a law? 

No - but NSIS is a de facto requirement for public IT deliveries, tenders and security matters, especially if you are part of critical functions. 

How does NSIS differ from ISO 27001? 

NSIS is based on ISO 27001, but adds requirements - e.g. for incident management, subcontractors and accessibility during emergency situations. 

What type of statement do you make? 

We use ISAE 3000 - either as Type 1 (point-based assessment) or Type 2 (period-based assessment of effective operation).
