Cyber4Z was founded in 2015 in Eindhoven, City of technology. We provide consultancy, product implementations, technical and process audits and projects in the field of cyber security and privacy. Currently we have acquired national and international clients in various industries such as multinationals, financial organizations, telecom and governmental institutions.


We have built a team of professionals with very different competences; from penetration testers to architects at tactical level but also from security specialists to risk managers at process level, both tactically and strategically. This enables us to successfully initiate and complete each assignment.

In addition to our permanent staff, Cyber4Z has a flexible layer of external professionals and suppliers with whom we regularly work together. We position our supplier independently, which means we can always make the most suitable choice for our customers.
