Digital Sovereignty in Business Software: Why “Hosted in Germany” Will Be Crucial in 2026

Digital sovereignty refers to the ability of companies to design, control, and further develop digital systems, data, and processes in a self-determined manner. This encompasses not only data protection and hosting location, but also the reduction of unilateral dependencies on providers, clear legal responsibilities, interoperability, the ability to switch providers, and control over decisions related to security and data protection.

For business software, this means specifically: A company must not only know where data is stored, but also who can access systems, under what legal framework the software is operated, and how dependent core business processes are on a single provider.

When companies discuss cloud strategies today, traditional criteria often still dominate: costs, scalability, features, depth, and integrations. All of these remain important, but they don’t tell the whole story.

Business software is no longer merely a supporting IT tool. It is the company’s operational nervous system. ERP, project management, resource management, CRM, and controlling systems serve as hubs for critical management information that extends far beyond individual processes.

Business software typically bundles:

Customer and contract data

Project calculations, hourly rates, and margins

Resource and capacity planning

Quotation logic, internal roadmaps, strategic priorities

Personal data (HR data, time tracking, roles, skill profiles)

Documents, communication, approvals, and decision-making processes

These systems not only map processes; they represent the business model itself

In many companies, project management, ERP, and business coordination systems are still regarded as “organizational tools.” In reality, they have long since become management tools: They determine how projects are prioritized, how resources are allocated, how margins are generated, and how transparently a company operates both internally and externally.

This is precisely why digital sovereignty in business software is now a resilience issue. It is not just about data protection, but about governance, reliability, and strategic control.

Anyone seeking to assess digital sovereignty should look beyond just the server location. In practice, five key factors are particularly crucial:

1. Legal sovereignty: Under which jurisdiction do data, operations, and support fall? What types of government access are legally permissible?

2. Data sovereignty: Who controls stored data, metadata, keys, roles, and access rights?

3. Operational sovereignty: How dependent is the company in its day-to-day operations on a single provider, its support, APIs, or operating model?

4. Technical sovereignty: How open is the system? Are there interfaces, export options, integration capabilities, and documented migration paths?

5. Strategic sovereignty: Does the software support long-term flexibility, or does it create a lock-in that complicates future changes, audits, or new requirements?

Only the interplay of these five levels reveals how sovereign a business software solution truly is.

Open Source, Open Standards, and Exit Capability

Digital sovereignty does not automatically mean that all business software must be open source. Nevertheless, open standards, documented interfaces, and reliable export options play a central role.

Companies are only sovereign in the long term if they do not confine data, processes, and integrations exclusively within proprietary platform logics. Therefore, questions such as the following are crucial:

Can data be exported in a structured manner?

Are interfaces documented and permanently usable?

Can third-party systems be integrated without complete dependence on the manufacturer?

Is switching providers realistic or only theoretically possible?

Sovereign business software reduces not only legal risks but also technical and economic dependencies.

Jurisdiction is a key factor in digital sovereignty, but not the only one. Equally important are control, transparency, interoperability, and the avoidance of structural dependencies on specific providers.

Many organizations feel secure because they say, “Our data is stored in the EU, after all.” Technically, that may be true. Legally, however, it is often not decisive. This is because, with U.S. providers, the geographic location of storage matters less than corporate affiliation—and thus the applicable jurisdiction. This is precisely where the U.S. CLOUD Act comes into play.

The CLOUD Act: Extraterritorial Access Powers by Law

The Clarifying Lawful Overseas Use of Data Act (CLOUD Act) requires U.S. companies to hand over data to U.S. authorities upon lawful order, regardless of where that data is physically stored.

What matters here is not the location of the data center, but the legal and factual control over the data. A disclosure obligation may exist in particular if the provider is subject to U.S. law,

is responsible for the software, platform, or operational management, or

has administrative access to the systems.

In these cases, a disclosure obligation may apply even if

the servers are physically located in the EU or a European data center is used, or

the customer is a European company.

The CLOUD Act is not an emergency or exceptional law, but permanently applicable U.S. federal law. It applies not only to terrorism or security cases, but also to investigations under general U.S. criminal and security law.

Many U.S. providers advertise “EU Data Residency” or “EU Region Hosting.” While this reduces latency and meets certain data protection requirements, it does not alter the legal ability to access data if:

the parent company is based in the U.S.,

key management, support, or maintenance are handled in the U.S.,

or U.S. personnel have administrative access.

This is precisely what the Stiftung Datenschutz has already explicitly pointed out. A 2025 statement notes, among other things, that providers such as Microsoft cannot rule out access by U.S. authorities, even with European hosting.

The decisive factor here is not whether access occurs regularly, but that:

it is legally possible,

cannot be fully controlled or prevented,

and companies cannot reliably rule it out to customers or supervisory authorities.

Why Standard Contractual Clauses (SCCs) and TIAs Do Not Solve the Problem

Many companies attempt to mitigate the risk through:

Standard Contractual Clauses (SCCs),

additional technical measures,

and Transfer Impact Assessments (TIAs)

However, these instruments have a clear limitation: they are effective only as long as the underlying legal framework remains stable and compatible.

The CLOUD Act, however, is structurally at odds with the GDPR, particularly with:

the principle of purpose limitation,

the transparency requirement,

and protection against disproportionate government access.

A TIA can clearly describe risks, but it cannot eliminate them if a provider is legally obligated to disclose data in cases of doubt. As a result, the TIA often becomes more of a documentation tool than a protective measure.

The “unpleasant triad” for companies with real-world consequences

This constellation creates a structural risk for European companies that cannot be “negotiated away”:

The use of cloud and SaaS services subject to U.S. jurisdiction is not merely a technical decision. It defines the extent to which a company retains control over its own data, processes, and decisions. The consequences are not evident in a single detail, but rather in the overall control and operational model.

1) Compliance becomes the norm; digital sovereignty remains out of reach

As soon as personal data or business-critical information is processed in U.S. SaaS systems, or U.S. providers have de facto control over operations, support, or administration, a permanent state of exception arises.

Digital sovereignty actually means: clear responsibilities, a clear legal framework, and predictable obligations.

US-hosted services have the opposite effect.

The ongoing additional effort includes, among other things:

Transfer Impact Assessments (TIAs) upon implementation and with every relevant change

extensive contracts and supplementary agreements

technical mitigation measures, the effectiveness of which must be regularly re-evaluated

recurring re-assessments in the event of changes in legal situations, court rulings, or geopolitical developments

Added to this is a key point:

Your argument must remain sound even if the rules of the game change.

Those who rely permanently on third-country mechanisms treat compliance as a reactive measure rather than an integrated part of corporate governance.

2) Access scenarios are beyond your control: a core problem of lacking digital sovereignty

A central feature of digital sovereignty is the ability to understand, control, and transparently limit access. This is precisely what is not fully possible with services subject to U.S. jurisdiction.

Even if an instance is operated as an “EU region,” the following remains true:

U.S. law can order access

Disclosure obligations can apply regardless of the storage location

Gag orders can prevent companies from even learning about an access request

Digital sovereignty is increasingly being contractually required, either explicitly or implicitly. Many B2B contracts, framework agreements, and tenders contain requirements regarding:

Data residency and jurisdiction

Subcontractors used

Auditability and control rights

Record-keeping for access from third countries

A lack of digital sovereignty thus becomes not only a compliance issue, but a direct competitive disadvantage, particularly compared to providers who operate their business software under clear European or German jurisdiction.

4) Reputational damage does not arise only from data breaches

A common misconception: Reputational damage arises only from security incidents or leaks.

In practice, however, even a public discussion about:

transfers to third countries

potential government access

unclear or contradictory documentation

can be enough. Especially in small and medium-sized enterprises (SMEs), where trust, long-term relationships, and personal connections are crucial, the impression of a lack of digital sovereignty can cause significant damage, even without a formal data breach.

Digital sovereignty is thus also a reputation and trust factor.

Digital sovereignty is not determined by individual features or user interfaces, but rather where business processes converge. In many European companies, this reality has already been achieved: core operations, communication, and decision-making rely on a few highly integrated cloud platforms.

This is not about “good” or “bad” providers. It is about risk profiles resulting from jurisdiction, operating models, and control capabilities.

In Europe, the following U.S.-based services in particular are widely used for business-critical purposes:

As long as these systems are used in isolation, the risk often remains abstract. But as soon as project management, communication, documents, approvals, and operational decisions converge on them, the dependency is no longer just “IT.” It is the business model.

Service providers in particular—whether they are consulting firms, agencies, IT service providers, engineering firms, or project management companies—often rely on established project management and ERP-related cloud systems from the U.S. This is understandable: rapid implementation, deep integration, and extensive ecosystems. At the same time, these systems centralize particularly sensitive data in one location, making the jurisdiction issue business-critical.

Solutions widely used in Europe that have headquarters in the US and hosting or access subject to US jurisdiction include, among others:

Atlassian (Jira, Confluence Cloud): project management, backlogs, documentation, internal decision-making processes

Salesforce (including PSA and ERP extensions): customer contracts, project finances, forecasts

Oracle (NetSuite): Financial data, project billing, resource planning

Workday: HR, role, and capacity data

ServiceNow: Service and project processes, internal workflows

Microsoft (Dynamics 365, Project, Planner): Project, customer, and company data closely integrated with M365

In practice, this is where the core processes of the service business converge: hourly rates, quotation logic, project margins, customer priorities, capacity utilization, escalations, internal evaluations. This makes these systems not just operational tools, but digital representations of the business model.

The risk arises less from individual functions and more from the concentration of business-critical information under a legal jurisdiction that does not guarantee European companies sufficient control in the event of an emergency. Even with “EU region” promises, the dependence on U.S. law remains, including potential access or disclosure obligations.

Many companies still view project and ERP software as mere organizational tools. In practice, however, they are key management tools. They determine how quickly decisions are made, how reliably planning is carried out, and how clearly business relationships are visible.

Digital sovereignty is no longer an abstract topic for the future. For many organizations, it is already business-critical today. A quick reality check will reveal whether it is still a “nice-to-have” or already a “must-have.”

The decision between a U.S.-dominated cloud stack and European ERP and business software operated under German jurisdiction is not a matter of preference or ease of use. It is a strategic choice regarding governance, control, and business resilience.

The differences rarely lie in the interface or feature set, but almost always in the risk and control model. That is precisely where the decision is made as to whether digital sovereignty is gained or lost.

Modern business software serves as a concrete example of how digital sovereignty requirements can be implemented, as it takes into account not only the hosting location but also the entire operational, security, and governance model. Key factors here include jurisdiction, transparency regarding access and roles, the degree of integration of business-critical processes, the auditability of operations, and dependence on proprietary platform structures.

BCS exemplifies this approach. Unlike traditional project management tools or isolated ERP modules, BCS, as business coordination software, follows a consistently integrated model: Core business processes are not connected via interfaces but are mapped within a single system. Project management, resource planning, time tracking, billing, as well as controlling and forecasting are directly interlinked, forming a consistent operational and financial management framework.

A key difference from many international cloud solutions lies in the underlying operating model. BCS is operated under German jurisdiction, with hosting in German data centers and clearly defined responsibilities between the provider and the customer. This eliminates dependence on U.S. law and extraterritorial access laws.

For companies, this means: business-critical information remains in a legally controllable and auditable environment—from project data and margins to internal management and decision-making processes.

The key difference, therefore, lies not in the range of functions but in the structure: Digital sovereignty here does not result from additional safeguards but is an integral part of the system design.

The use of BCS in various organizations demonstrates how digital sovereignty in business software actually impacts day-to-day operations. These real-world examples make it clear that the issue is not merely about hosting or legal jurisdictions, but rather about how securely, transparently, and controllably core business processes can actually be operated.

Westernacher Solutions GmbH develops IT solutions for particularly sensitive sectors, including public administration, the judiciary, the church, and notary offices. In these contexts, data protection, traceability, and audit-proof processes are not merely additional requirements, but fundamental prerequisites for day-to-day operations. Projects often navigate the tension between regulatory requirements, individual client needs, and long-term operational models.

As project complexity grew and demands for documentation and transparency increased, it became clear that isolated tools and fragmented processes were no longer sufficient. Westernacher needed a solution that not only supports individual tasks but enables end-to-end control across projects, resources, and the organization.

Against this backdrop, the decision to adopt Projektron BCS was a deliberate one: the goal was to establish a central platform that addresses both operational workflows and governance requirements. Today, BCS serves as an integrated system that brings together project planning, resource management, controlling, and administrative processes, thereby creating a consistent data foundation for all stakeholders.

A key benefit lies in standardization: processes are not only documented but also managed in a structured manner. Roles, responsibilities, and decision-making paths are clearly defined and traceable at all times. This creates transparency that supports both internal management and external requirements, such as those arising from audits or customer projects.

gematik GmbH is responsible for key components of Germany’s digital health infrastructure—an environment characterized by stringent regulatory requirements, complex coordination processes, and a multitude of concurrent projects. As a matrix organization, gematik operates with diverse teams, roles, and responsibilities that must be coordinated across projects.

Prior to the implementation of BCS, project and resource planning relied on several in-house developed solutions. However, these could no longer keep pace with the increasing complexity and the growing need for company-wide transparency and controllability. In particular, the lack of integration led to data silos and made reliable planning difficult.

The goal of the implementation was therefore clear: a central platform that consistently maps resources, projects, and capacities and makes them analyzable. At the same time, the solution had to meet the high requirements for data protection and access control, as sensitive information is processed across the organization.

msg global solutions is an internationally active IT and consulting firm with numerous subsidiaries and project teams located around the world. As the company grew, the need for consistent project management increased significantly: disparate systems, local solutions, and customized processes made comparisons difficult and led to inefficiencies.

Especially in an international context, it becomes clear that project management is more than just operational planning. It is about uniform standards, transparent data, and the ability to manage projects in a comparable manner across national borders. At the same time, local requirements—such as those related to regulation or billing—must continue to be taken into account.

The implementation of BCS therefore aimed to create a central platform that integrated all project-related processes—from planning and time tracking to billing. A key factor was the creation of a unified database that enables both operational control and management reporting.

Today, BCS is used across the entire group and forms the foundation for consistent project organization across more than 20 countries. The software makes it possible to establish global standards while simultaneously responding flexibly to local specifics. This not only creates efficiency but also sustainably improves the manageability of a complex international business model.

An additional advantage lies in the ability to systematically map different regulatory requirements. This is an aspect that is becoming increasingly important, particularly in the context of digital sovereignty and compliance.

These three use cases illustrate that digital sovereignty is not an abstract compliance issue, but rather has a direct impact on manageability, transparency, and resilience. When projects, resources, services, and key performance indicators converge in an integrated system, the business software itself becomes part of the operating model.

In these practical examples, BCS demonstrates that digital sovereignty arises not only from formal assurances, but from a combination of integrated system logic, clear responsibilities, transparent access models, and a legally predictable operational framework. This is precisely what distinguishes mere cloud usage from sovereign digital control.

By 2026, digital sovereignty will no longer be purely an IT or compliance issue. It concerns the question of how independently, controllably, and resiliently companies can operate their business-critical systems. This includes jurisdiction and data protection as well as interoperability, the ability to exit, transparent access models, and the reduction of unilateral vendor dependencies.

Those who outsource core business, ERP, and project-related processes to third-party systems are not only deciding on functionality but also on controllability, traceability, and long-term freedom of action. This is precisely why digital sovereignty is becoming a strategic selection criterion for business software.

“Hosted in Germany” is an important building block in this context, but true digital sovereignty only emerges when combined with clear responsibilities, auditable processes, transparent rights models, and a controllable system architecture.
