Why Linux? — The honest answer

Linux isn't the solution to everything—but it's the better choice for many things. Here are the main reasons:

True control over your system

While Windows and macOS come with forced updates, telemetry, and vendor lock-ins, a Linux system is truly yours. You decide when to update, which software to run, and whether to transmit data.

Cost-effective enterprise solutions

Linux itself is free forever. On top of that, there is a broad ecosystem of free software: LibreOffice instead of Microsoft Office, Thunderbird instead of Outlook, GIMP instead of Photoshop. For server workloads, Linux is already the standard.

Safety Through Design

Linux relies on an open permissions model, package-based updates, and resource-efficient default configurations. Less surface area for attacks, more transparency—without sacrificing functionality.

Hardware durability

While Windows 11 excludes older hardware and macOS runs only on Apple devices, Linux still manages to squeeze performance out of even aging systems. It’s sustainable and cost-effective.

Consulting & Support

Every project begins with an honest assessment of your situation. What’s working well, where are the weaknesses, and what goals are realistic? Based on this, we develop a concrete plan—with no vendor lock-in and no hidden costs.

IT-Assessments & Roadmaps

  • – Infrastructure analysis and vulnerability assessment
  • – Migration Planning (VMware → Proxmox, Windows → Linux)
  • – Hardware recommendations and capacity planning
  • – Compliance checks and security roadmaps

Hands-on Implementation

  • – Project management and implementation
  • – Documentation and knowledge transfer
  • – Post-implementation support and training
  • – Maintenance contracts and service level agreements
