Compare ISO 9001, ISO 27001 and NEN 7510

21 December 2025 | 2 min. read

ISO 9001 covers quality, ISO 27001 information security and NEN 7510 healthcare information security.

Customers requesting ISO 9001. A tender that requires ISO 27001 or NEN 7510. You increasingly need a certification to participate. But which certifier do you choose? On CertificeerWijzer you can compare certifiers for these three frequently requested standards.

ISO 9001 - Quality Management

ISO 9001 is the best-known standard in the world. This shows that your company works in a structured manner and delivers quality. Customers and clients often ask for it - especially during tenders.

Do you work B2B and do you want to show that your processes are in order? Then ISO 9001 is usually the first step.

ISO 27001 - Information security

ISO 27001 is all about information security. How do you handle customer data? How do you protect your systems? More and more clients require this certificate, especially if you have access to their data or systems.

Do you work in IT, consultancy or do you process sensitive data? Then ISO 27001 often comes into play.

NEN 7510 - Information security in healthcare

NEN 7510 is the Dutch variant for the healthcare sector. If you work with patient data - as a healthcare provider, IT supplier or supplier in healthcare - then this standard is often mandatory.

NEN 7510 builds on ISO 27001, but is specifically tailored to the requirements of the healthcare sector.

Compare certifiers

Nearly 50 certifiers are active in the Netherlands. They differ in price, approach and specialisation. One focuses on large internationals, the other knows your sector inside and out.

On CertificeerWijzer you can see which certifiers offer these standards and what their strengths are.

More standards step by step

We are expanding to other standards step by step:

  • ISO 14001 - Environmental management
  • ISO 45001 - Occupational safety
  • VCA - Safety, health and environment

Better three standards that you can rely on, than ten with half information. That is why we carefully build up the information for each standard.
