Technology may be complex. Operations should not be.
IT-Nerds GmbH is an owner-managed specialist consultancy focused on the technical analysis, planning, and implementation of robust IT and network infrastructure.
We provide vendor-independent advice, planning, and implementation for robust digital infrastructure in organisations where outages have real consequences. Networks, connections, and interfaces form the foundation.
For regulated, public, social, and outage-sensitive organisations.
Typical situations
You do not need to know the technical cause yet.
Tell us what is not working in operations, taking too much time, or becoming unnecessarily complex. We first clarify the problem, its context, and the technology already in place.
Disruptions and recovery
When outages recur or the path back to normal operations is unclear.
Unclear connections
When networks, interfaces, or statements from involved service providers do not align.
Accumulated complexity
When changes become hard to assess and operations take unnecessary time.
Only then do we recommend a technical measure or procurement—if it is actually needed.
Services
How you can engage us
We start with advice and planning, take on a defined technical implementation where useful, and support operations by agreement and where technically feasible—not as a blanket managed service.
Consulting & project planning
Structure requirements, risks, and decision paths.
Explore project consulting →Networks, routing & radio
Plan robust site networks, interconnections, and radio links.
Explore networks & radio →Linux, Open Source & Standards
Use open systems deliberately to improve maintainability and independence.
Explore Linux & open source →We work in regulated, outage-sensitive, and security-critical environments. There, technical decisions must not only work; they must also be verifiable, documented, and sustainable over the long term.
Many of our projects are subject to confidentiality. That is why we discuss tasks, approaches, and results—not customer names.
In a care facility, we designed and implemented decentralised, separated access for residents, visitors, staff, and operational services—with documented segmentation logic. Project evidence: segmented connectivity →
In a hospital environment, we combined existing paths and Linux systems into more resilient connectivity and handed over an assessment, documentation, and team briefing. Project evidence: resilient connectivity →
Regulated organisations
Experience in healthcare and finance as well as public and social institutions.
Critical operating environments
Work in outage-sensitive and security-critical contexts, including defence-related and classified-information environments.
Site networks & microwave links
Practical experience with distributed site interconnections, routing transitions, radio links, and microwave connections.
Open network platforms
OpenWrt, VyOS, OpenBSD, and OPNsense for transparent, maintainable infrastructure.
Approach
Understand first.
Then build.
Five steps from reviewing what exists to a documented handover.
- 01Map the information chain
Make relationships visible.
- 02Clarify the function
Who needs what, and what happens when it fails?
- 03Review what exists
Not everything needs replacing.
- 04Order dependencies
Use open standards where they help.
- 05Hand over operations
Document decisions and transfer knowledge.
Knowledge
Make technology understandable
Principles, methods, and common questions—explained clearly, without vendor brochure language.
Mindset / IT nerd
Do not stop at the first plausible answer.
Why scepticism, persistence, curiosity, and technical integrity make a difference in complex projects.

What do we need to bring under control together?
No form, no funnel—an email or a call is enough.
Briefly describe your situation; we will clarify the technical fit and whether and how we can support you.
