About Aquafin

At Aquafin, we connect people with water through technology. We lead change and work towards an environment in harmony with water. We do this through water purification and sewage, but also through innovation and energy transition.

Every day we contribute to better water quality and a healthy living environment. We realize infrastructure projects that collect and purify household wastewater and continuously work on optimizing our existing networks and installations. This supports the ambition to achieve ecological objectives for our waterways.

About the job

As an Information Security Analyst (Second Line), you will support the NIS2 implementation and the preparations for the audit for our organization (essential).

In this second-line role, you will independently assess the quality of documentation evidence and implementation evidence provided by the domains (first line) based on CyFun guidance. You will also validate that the evidence supports the scores and that they are not based on assumptions so that they will pass the external auditor's assessment. You will provide feedback to the domain owners and formulate concrete improvement points for them to work on.

Additionally, you will engage in file building, including a proof register that can be presented to the auditor without reworking.

We will first work towards the important level and you will continue to support the preparation for the essential level after April 2027.

You have 3 to 6 years of experience in information security, compliance, or IT audit. You are familiar with control frameworks such as CyFun, ISO 27001, and/or CIST CSF. You are able to interpret and assess technical evidence such as configuration exports, log files, tickets, recovery, and scan reports. Your role is situated in the second line and does not include operational tasks such as pentesting, SOC activities, or engineering.

The position reports to the CISO and requires a critical, analytical, and independent attitude. The CISO supports you in case of doubt, methodology, and escalation. The first line is responsible for self-assessment, providing evidence, and remediation.

  • Independently assess the quality of documentation evidence and implementation evidence
  • Validate that evidence supports scores and is not based on assumptions
  • Provide feedback to domain owners and formulate concrete improvement points
