Both ISO 27001 and NEN 7510 are about information security. Both standards help organizations manage risks and protect data properly. Nevertheless, they are still often confused. Basically, they look alike, but the NEN 7510 is specifically aimed at the healthcare sector in the Netherlands. ISO 27001 is the international standard that is applied in all sectors. The difference therefore lies mainly in the scope and the additional requirements.

What is ISO 27001?

ISO 27001 is an international standard for information security. The standard describes how to Information Security Management System (ISMS) furnish. This gives you a grip on risks, processes and responsibilities.

 

The ISO 27001 standard consists of requirements for policy, risk management, internal audits, improvement measures and the role of management. The goal is to make information security a structural part of your business operations.

 

An organization that meets all requirements can have a ISO certificate achieve. This shows that you have information security demonstrably and continuously in order.

 

What is NEN 7510?

NO 7510 is the Dutch standard for information security in healthcare. The standard is based on ISO 27001, but includes additional requirements that are specific to the healthcare sector.

 

The reason: healthcare works with patients' sensitive medical data. The protection of this data requires additional safeguards. NEN 7510 therefore describes additional control measures for, among other things, access to patient information, logging and compliance with the AVG.

 

Healthcare institutions and their suppliers must be able to demonstrate that they comply with NEN 7510. One NEN 7510 certification shows that the organization is careful with health information.

 

The main differences between ISO 27001 and NEN 7510

Although NEN 7510 builds on ISO 27001, there are a few clear differences:

Aspect ISO 27001 NEN 7510
Toepassing Internationaal, toepasbaar in alle sectoren Specifiek voor de zorg in Nederland
Basis Algemene eisen voor informatiebeveiliging Gebaseerd op ISO 27001 + aanvullende zorgspecifieke eisen
Doelgroep Alle organisaties, van mkb tot enterprise Zorginstellingen en leveranciers die met patiëntgegevens werken
Risicoanalyse Gericht op algemene bedrijfsrisico’s Gericht op risico’s rondom patiëntveiligheid en medische data
Certificering ISO 27001-certificaat NEN 7510-certificaat, eventueel in combinatie met ISO 27001
Wetgeving Ondersteunt o.a. AVG, NIS2, BIO Ondersteunt o.a. AVG, NIS2 en zorgspecifieke wetgeving (zoals Wkkgz)

How do ISO 27001 and NEN 7510 relate to each other?

ISO 27001 forms the basis. NEN 7510 is, as it were, one floor on that.

An organization that has already introduced ISO 27001 often largely meets the requirements of NEN 7510, so you only have to implement the additional care-specific components.

 

Conversely, those who are NEN 7510 certified automatically comply with the most important parts of ISO 27001, which is why both certifications are often carried out together, in one process and with one combined NEN 7510 audit.

 

ISO 27001 and NEN 7510 are about risk management

Both ISO 27001 and NEN 7510 revolve around risk management. A good one ISO 27001 risk analysis whether NEN 7510 risk analysis forms the core of the management system. ISO 27001 focuses on business risks: how do threats affect the continuity and reliability of your organization? NEN 7510 focuses on patient safety and the confidentiality of medical information. Think of situations where incorrect access to data can have direct consequences for healthcare provision.

 

Which standard applies to you?

  • Do you work in the care or do you process medical data for healthcare institutions? Dan is NEN 7510 certification mandatory or highly recommended.
  • Do you work in a different sector, or do you want to demonstrate compliance with customer requirements and legislation? Dan is ISO 27001 the right choice.

Some organizations consciously opt for both certificates. This way, you demonstrate that you not only comply with the international standard, but also with the specific Dutch healthcare standard.
