ISO 27001

  • Is ISO 27001 certification mandatory? The certification is not mandatory; however, clients sometimes demand ISO 27001 certification, or it is requested at tender. If you have a certification, this provides certainty for your customer. In addition, it is your proof that you comply with the ISO requirements for information security.

  • You have a competitive advantage and are therefore distinctive from other organizations (also in tenders).

ISO 27001 implementation

The basis of ISO 27001 is the implementation of an information security management system (ISMS). In it, you record, among other things, which controls you have taken with regard to information security. Besides the technical aspect of information security, the role of man is central here. If you set up the system in accordance with ISO 27001, you can have its operation tested and certified by an independent body.

ISO 27001 certification costs

We are happy to perform the audit for you that is required to obtain the accredited certification. The costs of certification depend on several factors. For example, the size (number of sites or FTEs) and complexity of your organization. As every organization is unique, we are happy to discuss your starting position with you and identify which steps (may) still need to be taken to be ready for certification. We can then make a customized certification proposal.
