How Total Energies Charging Solutions Netherlands obtained more than one certificate with the implementation of ISO 27001
Highlights of this success story

The reason
Shortage of ISO 27001 knowledge and capacity
TCSNL was struggling with a shortage of capacity and in-depth knowledge of the ISO 27001-standard. “Preparing for the audit was a complex task that required both specialist knowledge and manpower,” says Stefan Evers, Managing Director. “Unfortunately, our own Security Officer was unable to bear this extra burden.” What's more, ISO 27001 goes beyond cybersecurity alone. It includes optimizing all business processes with information security as a central theme. This requires support throughout the organization and therefore a broader approach than purely technical measures.

Our approach
The role of an external colleague
Fendix took the role of implementation partner in itself. As a result, Jelle started his job and, as an external colleague, worked closely with the TCSNL team to integrate the necessary knowledge and optimize business processes, with information security as a key point. In addition to working with management to get their support, we also explained why information security is so important to the entire organization.
For employees, it often seems like a long way from my bed show. Everyone works with certain systems or wants insight into certain documents, and then suddenly a specialist comes and makes rules for this. Jelle van Fendix set out the lines perfectly and communicated clearly, so that employees increasingly got a sense of the subject and became involved. Jelle did this by looking for information from the right responsible people, sitting around the table, making sure you receive the right information, setting deadlines, and staying in touch.

The results
Passed ISO 27001 audit with flying colors
The hard work paid off. In April 2024, TCSNL passed the audit with flying colors. “We received one point for improvement and no shortcomings. A proof of our professionalism and Fendix's thorough approach,” says Stefan. Here, too, Jelle had an important role. He was responsible for preparing the documentation and ensuring that these documents were “ISO-proof”, which ensured that all required documentation was available, checks were carried out, and evidence collected.



More than just a certificate
ISO 27001 certification is more than a piece of paper. It has changed how TCSNL deals with information security. It is an important part of business operations, with attention for both current and new employees. “Every new employee immediately receives training on what the certification entails and what we want to achieve as a company,” says Stefan.
One of the biggest changes is stricter control over access to documents, systems, and locations. This is based on the “need-to-know” principle, with extra attention to risk assessment. “Our growth ambitions require regular monitoring of these processes,” says Stefan.
This partnership with TCSNL shows what a strong partnership can achieve. Together, we have not only achieved ISO 27001 certification, but also laid a firm foundation for continuous improvement of information security.
