Welcome to Nefkens Advies, the independent consultancy company from Cisco Champion Pieter-Jan Nefkens. Nefkens Advies has expert knowledge on ICT infrastructures with specialisms on network infrastructures, DNA Centers and cybersecurity. Nefkens Advies can assist and support you in different ICT related infrastructure items.


Do you run into ICT related problems or issues? Would you like to know more about digitilisation, Cisco’s DNA-Center and what the impact is for your organisation? Or how to handle developments such as Automation, Software Defined Access or specific questions about your network infrastructure or security? Or would you like to be informed about the trends and developments within Infrastructure and its impact? Or did you recently have a (major) disruption in your service and would like to know the cause? Nefkens Advies can support you with all these questions. We like to help you answering these and other ICT related questions for your organisation in advisories tailored for your organisation.

Design & Implementation

Are you on a crossroad on your ICT infrastructure strategy? Do you need assistance in the design and implementation of your ICT infrastructure? Do you need an ICT infrastructure architecture design and the roadmap how to implement it? Nefkens Advies has more than 15 years of experience in the design and implementation of (network)infrastructures aimed for your needs, wishes, processes and your organisation.


Maintaining knowledge is essential for any ICT department or organisation. Learning the right things and adopting them is even more critical. And there is of course plenty of training material in the form of standard courses and videos available. The disadvantage of this material that it is not related to your organisation and your staff. Or the training material is to generic and does not contain the latest developments.

Does this sound familiar to you? Do you or your team have a need to know how or what a specific technology impacts your organisation? Or do you have the need to learn more about a specific solution in detail? Then the training solutions of Nefkens Advies can work for you. Based on one or more intakes a training specific for your team is made and given on location. This way your team receives the appropriate knowledge and your own goals.
