Service

Open Source & Sovereign IT

European platforms and open standards – full control over where your data resides and the freedom to change provider.

Our approach

Control over your data and your platforms

Many organisations operate their files, email and collaboration on the platforms of a few global providers, with limited influence over data location, access and future commercial terms. For organisations that process sensitive information, this dependency is a strategic risk.

We design and operate alternatives based on open standards and European technology, so that you determine where your data resides and who can access it. Digital sovereignty is not an all-or-nothing decision: where public cloud services are the right choice, we integrate them with platforms that remain under your control.

Scope of services

Open, European, under your control

  • 01

    Private cloud with Nextcloud

    File sharing, calendars and collaboration on open-source software, operated in your own data centre or in infrastructure you control, with defined rules on data location and access.

  • 02

    Open standards and formats

    Platforms and data formats that remain portable, so that a change of provider remains a business decision rather than a technical obstacle.

  • 03

    European security technology

    Security technology developed in Europe, such as R&S LANCOM Unified Firewalls from Germany, whose cloud sandbox is hosted in Germany.

  • 04

    Hybrid architectures

    Microsoft 365, Azure or AWS where they are the best fit, combined with systems under your own control and a clearly defined boundary between both.

How we work

From dependency to choice

  1. 01

    Data classification

    We establish which data you hold, where it resides today and how sensitive it is.

  2. 02

    Target architecture

    Together we decide which services belong on platforms you control and which remain in the public cloud.

  3. 03

    Implementation and migration

    Platforms are implemented, data is migrated and users are trained in planned stages.

  4. 04

    Operation

    We operate, update and monitor the platforms, so that open source does not require you to build in-house expertise.

Frequently asked questions

Is open-source software suitable for business-critical use?

Open-source software is used by public authorities and large enterprises worldwide. Because the source code is public, vulnerabilities can be identified and resolved by a broad community. What matters most is professional configuration, maintenance and operation – which is what we provide.

Do we have to give up Microsoft 365?

No. Many organisations retain Microsoft 365 for day-to-day work and move only sensitive data or specific services to platforms under their control. We help you define that boundary.

Who is responsible for support and operation?

We are. We operate and maintain the platforms we implement, with the same 24/7 monitoring we provide for networks and servers.

Want more control over your data?

Tell us which systems you would like to move to open, European platforms. We will assess with you what makes sense and how to get there.
