Below are the projects we have reported on publicly and the clients who have trusted us for years. We provide a reference contact from your industry on request, with the client's permission.

Case studies

Three projects from the past year: what the problem was, what we did and what changed.

Hospitality · Slovenia · 2026

Hotel Ptuj

Challenge
The hotel needed an IT environment that simply works for guests and staff: one network for guests, another for operations, telephony, TV and the hospitality system, all from one provider.
Solution
Together with Inovis we designed and built the network and servers, VLAN segmentation with separate guest and internal networks, Wi-Fi, IP telephony, TV and the hospitality system.
Result
A stable and secure digital environment for guests and staff on one infrastructure, with one point of contact for all systems.

Energy · Slovenia · 2026

Kočevje Solar Park

Challenge
A solar plant with energy storage needs a network that is both reliable and protected: control devices must not be reachable from outside, and communication between them must run without interruption.
Solution
We designed and built a secure industrial network: segmentation, network equipment configuration and secure communication between the plant and the storage.
Result
A reliable, secure and scalable environment for the plant and the energy storage, ready for the park's expansion.

Healthcare · Germany · 2026

Onko-Medeor Institute

Challenge
The institute ran its own Exchange e-mail server and wanted to move to Microsoft 365 without staff losing their mail and without data leaving control during the transition.
Solution
With partner Sonextis GmbH we carried out the migration remotely between Slovenia and Germany, with data security looked after throughout the process.
Result
A transition with no disruption at all for end users; the institute has a modern cloud e-mail environment without its own server.
