Networking & Provisioning
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects. Steve Kirchner Managing Director, nextGYM GmbH View project International

Selected projects Read client reviews While looking for a partner to integrate a local AI solution, we came across Timo and Robin - and could not have made a better decision.
They quickly understood our requirements and solved technical challenges competently and pragmatically.
We were particularly impressed by the straightforward collaboration, their high level of expertise and the speed of implementation.
We are delighted to have Timo and Robin at our side as reliable business partners and look forward to our next projects together. (translated) Henrik Jeche Head of IT Administration ml&s - full-service provider for the electronics industry. · Germany · Local AI Integration · Technical Integration · Implementation Read full review WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT. John Hellmerichs Managing Director, AInergy GmbH AInergy - consultancy for energy and facility management. · Germany · Proxmox & Virtualization · Backup · VPN · Security Read full review WZ-IT manages our Proxmox cluster reliably and professionally. The team handles continuous monitoring and regular updates for us and responds very quickly to any issues or inquiries. They also configure new nodes, systems, and applications that we need to add to our cluster. With WZ-IT's proactive support, our cluster and the business-critical applications running on it remain stable, and high availability is consistently ensured. We value the professional collaboration and the noticeable relief it brings to our daily operations. Pascal Hakkers Aphy AG Aphy AG - AI platform for hotel back-office. · Switzerland · Managed Proxmox · Cluster · Monitoring · High Availability Read full review Professional, honest and technically thoroughly sound: WZ-IT set up our Proxmox and backup infrastructure securely and future-proof. The consulting from Timo and Robin was objective and needs-driven, the implementation smooth and the final documentation exemplary. You can tell immediately that business-critical infrastructure is thought through holistically from the outset here and implemented with clear ownership. Pascal Block Head of IT & Processes, Stadtwerke Brühl GmbH Stadtwerke Brühl - municipal energy and infrastructure utility. · Germany · Proxmox & Backup · Proxmox · Backup · Documentation Read full review The knowledge from many years in the solar industry lived in the head of our former managing director, and it still lives in the heads of our employees today. We wanted to secure it, not as a folder full of notes, but in a way that lets us ask questions in daily work and get reliable answers. WZ-IT advised us from the start and weighed different approaches and knowledge management systems against each other with us before we decided. What was built is a custom knowledge base with an AI assistant that brings together conversations, notes, documentation and manuals: from the platform through onboarding our team to support in operation. Conversations are transcribed and facts are extracted; we review and correct everything ourselves before it is stored, because we do not want to trust an AI blindly. The system runs in our own environment, and the data stays with us. What surprised us was how efficient it was: WZ-IT used existing open-source software and extended it specifically for our requirements, instead of selling an expensive custom build from scratch, as is often usual with IT service providers. Timo and Robin understood our actual problem, preserving knowledge during the generational handover, and implemented it step by step: from the proof of concept through setup and validation with our own data to productive operation, explaining everything clearly along the way. Next, we want to extend this to the knowledge of our employees, so that this does not depend on individual people either. Joshua von Ameln Managing Director, solarwerkstatt berlin GmbH solarwerkstatt berlin - solar industry, preserving knowledge across a generational handover. · Germany · Knowledge Management & AI · Knowledge Base · AI Assistant · Open Source Read full review We were looking for a secure yet easy-to-use alternative to the large American providers and came across WZ-IT. WZ-IT advised us on choosing the right models and implemented the integration for us. Beforehand, we were able to try everything out calmly on a test instance. Today WZ-IT runs Open WebUI for us on our own domain, with a convenient Microsoft login and open-source models hosted by a German provider. Our team can now work productively with AI without resorting to external tools or shadow AI. Working together is straightforward, and questions are answered quickly and clearly. With WZ-IT we also have a partner at our side for further AI projects. (translated) Carl-Frederic Korn Head of E-Commerce & Online Marketing, Krüger Dirndl GmbH Krüger Dirndl - traditional fashion and e-commerce. · Germany · AI Platform · Open WebUI · Test instance · Microsoft login Read full review Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time. Christoph Mußmann Project Officer, DGHO e.V.

Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us.

The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated) Matthias Zimmermann Managing Director, Annota GmbH Annota - healthtech startup with an AI documentation assistant. · Germany · Open Source Architecture · Implementation · Technical Consulting Read full review Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration!
