Open-Xchange
and digital sovereignty

For the last two decades, Open-Xchange has been on a mission to offer open-source-based software alternatives to solutions from Big Tech companies. Having partnered with some of the world’s largest Internet Service Providers (ISPs), hosters and telcos, we are now bringing our commercial experience to the public sector, to help maintain and expand digital independence, and prevent the risks arising from the dominance of a small number of providers.

Digital sovereignty in danger

Sovereignty is all about choice, and this applies to private individuals, as well as to states. When it comes to digital sovereignty, the federal government and entire public sector have faced a series of challenges when it comes to the software they use for work. This is because, with the advent of cloud technology and the strong market position of a few – mostly US – providers for digital workplace software, there aren’t many alternative solutions. In addition, the market-leading providers are increasingly pushing their customers into ‘special’ usage models.

This included an announcement from one vendor that, in the near future, its software could only be obtained from the company's own cloud. The use of cloud software in this way means that any associated data would no longer be stored on the users’ own servers. As a result, the public sector will lose control and data sovereignty, because the cloud installations of many providers are distributed globally.

Another key point is that these hyperscale vendors normally fall under US jurisdiction and the Cloud Act, which states that US authorities and law enforcement agencies can request access to the stored data at any time if there is good reason.

This is simply unacceptable for the federal government and federal states, as part of a state's sovereignty is in protecting its data and documents. This primarily concerns confidential documents, including those around planning, budgets, science, security, and defense (other areas, such as culture, require less protection).

Open-source software offers an alternative

The German government has reacted and, led by the Federal Ministry of the Interior and Homeland (BMI), an intensive debate has begun around solutions that remove the dependence on software delivered by market-dominating providers; The federal states and the European Union were also involved.

The solutions cover a wide range of applications and are still under development and will remain so, as the entire environment is developing dynamically. They also include cloud models adapted to the needs of public sector because, in addition to protecting digital sovereignty, there is a want to operate IT systems more efficiently.

A public infrastructure for hosting applications and data is to be established and open-source software will play an important role in this. At the national level, the federal cloud has created services with graduated levels of security. From a protected area for classified information, to services with lower-level security requirements, for which partners are also involved.

The IT Planning Council adopted a strategy for a German Administration Cloud (DVS) in 2021, and this is being developed on a broader basis with the assistance of companies including Open-Xchange, Dataport and IONOS.

A "Sovereign Workplace"

When it comes to applications, the German government wants an open-source alternative to those email and collaboration platforms from the hyperscale vendors. The BMI has created the working name of 'Sovereign Workplace' (Souveräner Arbeitsplatz), and the dPhoenix suite is a reference implementation that combines all the required tools. The BMI has commissioned Open-Xchange’s partner Dataport to develop the suite further.

Open-Xchange delivers its groupware, OX App Suite, along with its Dovecot email server software to the project. Together with other partners, including Univention, we are developing a ‘Sovereign-Workplace-as-a-Service’ in the cloud.

Federal states benefit from Open-Xchange’s open-source know-how and products and, as all solutions are cloud-based, there is no need for time-consuming installation on site. As a result, some states use our solutions in the education sector. They also benefit from the open-source community and partners such as Heinlein, ownCloud and Univention.

In addition, this approach also means that federal and state governments can choose which cloud provider they want to obtain their services from.

Solutions

German solutions provide real alternatives to large technology companies

Open-Xchange works directly with a number of best of breed German open-source software vendors to deliver solutions specifically designed for public sector users. As a result, customers don’t have to combine software from various vendors themselves – instead, they have access to a complete digital workplace solution. In addition, they can choose where their data is stored and who can access it – regardless of whether it is cloud-based, in their own data center, in a service provider’s data center or on-premise.

Our partners are committed to ensuring digital sovereignty and protecting privacy, and adhere to the European Union’s (EU) General Data Protection Regulation (GDPR). As a result, any solution offers a secure open-source alternative to those from international hyperscale vendors.
