Our core values

Our starting point is the essential pillars of customer focus, craftsmanship and quality, the basics you should expect from a commercial company. What really set us apart are our core values. Relined is connecting and essential in the digital infrastructure market for several reasons:

Core value: connecting


Relined plays a crucial role in connecting commercial and public networks. We stand for strategic and sustainable partnerships with both public and private parties, with the aim of providing secure connectivity through a stable and fine-grained digital infrastructure.

Core value: reinforcing


By using sovereign networks, which are often located in protected and less accessible areas, Relined offers an increased level of digital security and stability. This is crucial at a time when data security and network integrity are of paramount importance.

Core value: future-proof


Relined is committed to the sustainable growth of digital connectivity. This is important not only for today's digital economy, but also for future development and innovation. By deploying the unused capacity of existing fibre networks, we are making efficient use of existing resources. This leads to cost savings and reduced environmental impact while increasing network capacity and accessibility.

Core value: nationally anchored

Nationally anchored

As a subsidiary of Netherlands state-owned company TenneT, we contribute to digital growth with a long-term oriented approach. We are committed to a future-proof and uniquely located fibre infrastructure. We do this based on a strong focus on safety and stability.

Corporate Social Responsibility

Relined wishes to make a valuable contribution to society. We are already doing so by optimising the use of existing network capacity and preventing the unnecessary building of new networks. But that’s not all. As part of CSR, we have entered into a cooperation with JINC. Together, we work for socioeconomically disadvantaged young people. By making employees available as volunteers in the role of trainer or coach. Or by organising accelerated internships, so that the kids can take ‘a look behind the scenes’ and carry out practical assignments. Want to find out more about JINC and the possibilities?

Relined Fiber Network prides itself on high quality and security of information. The certifications we have, ISO 9001 and ISO 27001, demonstrate that we fulfill the standards set for both. Each year, an external auditor assesses whether we still comply with all requirements. But this doesn’t mean that we rest on our laurels the rest of the time. Not at all! We are constantly working to maintain the high quality and optimum provision of our services. We make every effort to assure the security of all forms of information within our organisation.

A summary of the certifications we hold:

ISO 9001

ISO 9001 is the worldwide standard for quality management, a measure of the transparency and reliability of an organisation – and therefore of ours. Put another way, do we say what we do and do what we say? Quality management is reflected in every aspect of our organisation and we are always working with this in mind on maintaining quality and the optimum provision of services towards our customers.

ISO 27001

ISO 27001 is the standard for information security, worldwide. It shows that an organisation complies with the strict requirements surrounding information security and that the organisation takes privacy seriously. Data security is at the top of our agenda.  We do everything to ensure that the security of all forms of information is assured.
