Digital Sovereignty in the Cloud: Seizing Opportunities, Avoiding Risks

Cloud services, SaaS applications, data platforms, and AI solutions have long been an integral part of everyday business operations for many companies. For SMEs in particular—whose core business does not lie in IT—this raises an important management question: How dependent is your company on individual technology and cloud providers? Which data, applications, and processes are truly critical? And how capable will you remain of taking action if prices rise, services fail, legal requirements increase, or geopolitical developments affect access to digital infrastructure?

Digital sovereignty is therefore not purely a technical issue. It involves strategic decisions by management regarding risks, investments, vendor selection, data locations, compliance, and future viability. The goal is not to become completely self-sufficient or to operate all systems in-house. Rather, what matters most is being able to act independently: with control over critical data and processes, clear responsibilities, robust alternatives, and the freedom to switch providers or operating models as needed.

What is digital sovereignty?

In short: Digital sovereignty describes a company’s ability to use, evaluate, and further develop digital technologies, data, infrastructure, and its relationships with providers in a self-determined, secure, and legally compliant manner.

A concise definition of digital sovereignty is: Digital sovereignty is the ability to remain capable of acting in the digital space, to consciously manage dependencies, and to retain control over critical data, systems, and decisions.

For companies, digital sovereignty encompasses several dimensions:

• legal sovereignty, such as regarding data protection, data locations, and contract drafting
• economic sovereignty, such as through reduced dependencies on providers and greater bargaining power
• technical sovereignty, such as through portability, interoperability, security architectures, and the ability to exit

For SMEs, this means above all that they do not have to do everything themselves, but they should know where critical dependencies exist, what risks arise from them, and how they can remain capable of acting in an emergency.

What does digital sovereignty mean for businesses?

It does not mean developing all IT systems in-house, using only European providers, or ruling out global cloud platforms across the board. Rather, for executives and management, it is about making informed and robust decisions.

Digital sovereignty means being able to assess which providers, cloud models, data locations, security mechanisms, and operating models align with your business model, risk tolerance, and regulatory requirements. A manufacturing company with sensitive design data has different requirements than a retail company with highly seasonal peak loads. A company in the healthcare, energy, or financial sectors, in turn, must take into account different compliance and security requirements than an unregulated service provider.

The key question for management is: Which digital dependencies are acceptable, which must be actively reduced, and where do you need alternatives?

The Difference Between Self-Sufficiency and Digital Sovereignty

Digital sovereignty lies between two extremes. On one side is external control: providers, platforms, proprietary technologies, or external legal jurisdictions limit your ability to act. On the other side is self-sufficiency: the attempt to operate and develop everything on your own and to be independent of external partners.

For most SMEs, self-sufficiency is neither realistic nor economically viable. Modern companies benefit from specialized cloud providers, high-performance platforms, and external expertise. Digital sovereignty, therefore, does not mean isolation, but rather freedom of choice. You remain open to partnerships while retaining control over critical decisions, data, and options for change.

Why Digital Sovereignty Is Becoming a Management Challenge for SMEs

Many companies today use cloud services, SaaS solutions, external infrastructure, data platforms, and AI applications without fully understanding their actual dependencies. It is often clear which tools are in use. What is less clear, however, is which data flows where, which contractual terms apply, which chains of providers are involved behind the scenes, and how quickly a switch or recovery would be possible in an emergency.

For this reason, digital sovereignty should not be delegated solely to the IT department. IT can analyze risks, evaluate architectures, and implement technical measures. However, the decision regarding which risks are acceptable from a business perspective, which investments should be prioritized, and which vendor strategy to pursue belongs at the management level.

Dependence on a small number of cloud and technology providers

Vendor lock-in occurs when data, applications, or processes are so tightly tied to a specific provider that switching is only possible with significant effort, high costs, or considerable risk. This can result from proprietary interfaces, specialized data formats, tightly integrated platform services, licensing models, or a lack of internal expertise.

For companies, this means that their bargaining power decreases, price increases are harder to mitigate, and technical decisions are increasingly shaped by existing vendors. A well-thought-out cloud strategy does not create immediate independence here, but it does ask the right questions: Which systems are particularly critical? Where do we need options for switching? Which architectures should be designed to be more portable in the future?

Geopolitical Risks and Access Restrictions

Cloud and technology dependencies are not merely technical or economic issues. Global platforms are subject to different legal jurisdictions, political frameworks, and international tensions. Sanctions, export controls, access restrictions, or changing regulatory requirements can influence which services are available and under what conditions data is processed.

Particularly relevant in this context is the conflict between European data protection requirements and non-European access powers. Under the CLOUD Act and FISA Section 702, U.S. providers are subject to a legal framework that grants U.S. authorities access to data, regardless of whether the data is stored in the U.S. or in a European data center. This right of access may directly conflict with the GDPR and cannot be resolved simply by choosing the location of storage.

This does not mean that global cloud providers must be ruled out entirely. Rather, it is crucial to carefully assess the legal framework and design cloud strategies in such a way that critical data, core business processes, and regulatory requirements are adequately protected.

Complex Regulatory and Compliance Risks

The GDPR, industry-specific requirements, and NIS2 are increasing the pressure on companies to professionally manage their digital risks. The more critical the data and processes are, the more important transparent data processing, clear accountability, technical safeguards, and auditability become.

For management, this means that compliance is not just a matter of documentation. It is directly linked to cloud architecture, the selection of providers, data flows, and the ability to demonstrably implement security and data protection requirements. Digital sovereignty helps establish this transparency.

Cybersecurity, Data Leaks, and Information Security

Digital sovereignty and cybersecurity are closely linked. Companies need to know who has access to data, how systems are secured, how quickly they can respond to incidents, and whether critical services remain available even during crises.

A lack of transparency regarding chains of providers, interfaces, and responsibilities increases the risk of misconfigurations, data leaks, and delayed responses to security incidents. A sovereign cloud strategy lays the foundation for better information security through clear governance, defined responsibilities, robust contingency plans, and controlled data processing.

What makes a cloud a sovereign cloud?

A sovereign cloud is a cloud environment that gives companies more control over data, infrastructure, operations, provider dependencies, jurisdictions, and options for switching providers. It is important to note that a sovereign cloud is not a single product that can simply be purchased. It is a strategic approach encompassing architecture, provider selection, data classification, security strategy, governance, operations, and an exit strategy.

A sovereign cloud must therefore always be tailored to the company. Not every application requires the highest level of protection. Not every workload needs to run in a European cloud. However, critical data, regulated processes, and business-critical applications should be carefully evaluated and appropriately secured.

Guidance Based on C3A Criteria and the EU Cloud Sovereignty Framework

To ensure that digital sovereignty in the cloud does not remain an abstract concept, recognized criteria and evaluation frameworks help with classification. These include the BSI’s C3A criteria and the EU’s Cloud Sovereignty Framework. Both frameworks describe the dimensions relevant to the evaluation of sovereign cloud offerings, such as strategic control, legal frameworks, data sovereignty, operational independence, supply chains, technological openness, and security and compliance aspects.

For management, the goal is not to technically assess every criterion themselves. It is more important to determine what level of sovereignty the company requires, which criteria must be met given its risk and business profile, and which are of secondary importance.

The frameworks provide a structured basis for this. They help compare cloud offerings not only in terms of cost, feature set, or performance, but also in terms of how well they support control, transparency, the ability to switch providers, and long-term operational flexibility.

Data Sovereignty and Controlled Data Processing

Data sovereignty begins with transparency: Where is data stored? Where is it processed? Who can access it? Which jurisdiction governs its processing? And what technical and organizational safeguards are in place?

For management, this transparency is crucial for assessing risks and clearly defining responsibilities. Particularly sensitive data should be classified, protected, and processed only in environments that meet the organization’s own requirements for security, data protection, and compliance.

Portability and Exit Potential

Sovereignty is evident not only in day-to-day operations but also in the ability to switch providers. In this context, portability means that data, applications, and workloads are designed so that they can be transferred and continued to operate across different cloud environments, platforms, or providers with reasonable effort. Data and applications should, whenever possible, be designed so that they are not permanently tied to proprietary mechanisms.

Open standards, documented interfaces, containerized architectures, and clear data exports can make switching providers easier. This does not mean that a switch must be planned at all times. But having the option to switch strengthens your bargaining power and reduces strategic risks.

Interoperability Instead of Proprietary Silos

Interoperability means that systems can communicate with one another without every new project becoming a custom solution. For companies, this is a key lever for flexibly developing their digital landscapes.

Proprietary siloed solutions may be convenient in the short term, but they often make it difficult to integrate new technologies, data platforms, or AI applications. Open interfaces and modular architectures increase flexibility and create better conditions for innovation.

Resilience and Availability

A sound cloud strategy also takes into account outages, access restrictions, and crisis situations. What happens if a central service becomes unavailable? Which processes come to a standstill? How quickly can data be restored? And who makes decisions in an emergency?

A resilient cloud strategy includes contingency plans, redundancy, backup and restore procedures, clear responsibilities, and regular testing. For small and medium-sized businesses (SMEs), it’s important to note that resilience doesn’t have to be maximal—it just needs to be appropriate. The key is to specifically safeguard business-critical processes.

Open Source and Open Standards

Open source should not be viewed through an ideological lens, but rather as a potential building block for digital sovereignty. Open technologies can promote transparency, verifiability, portability, and independence. They make it possible to further develop systems over the long term and reduce dependence on individual vendors.

At the same time, open source alone is no guarantee of security or sovereignty. Professional operation, clear responsibilities, regular updates, security processes, and the right expertise are crucial.

Opportunities Presented by a Digitally Sovereign Cloud Strategy

A well-thought-out cloud strategy is not just about risk management. It also opens up business opportunities. Companies that understand their dependencies and deliberately design their cloud landscape can grow in a more controlled manner, integrate new technologies more easily, and better comply with regulatory requirements.

Greater control over data and critical business processes

With improved transparency and governance, you’ll know which data, applications, and processes are truly business-critical. This allows you to prioritize protective measures more effectively. Instead of striving for the same level of security across the board, you can allocate resources where they provide the greatest business value.

Reduced Risk of Vendor Lock-in

A well-thought-out cloud strategy doesn’t mean immediately replacing existing providers. However, it does create options for switching. This strengthens your bargaining power, reduces dependencies, and prevents your company from ending up in a technological dead end in the long run.

More flexibility for new technologies

Open standards and modular architectures make it easier to integrate new platforms, data solutions, and AI applications. By designing a flexible cloud landscape, organizations can test new technologies more quickly, integrate them more securely, and scale them if they prove successful.

Improved Compliance and Legal Certainty

Clear data flows, defined responsibilities, and appropriate cloud architectures help organizations better meet regulatory requirements. This applies to data protection, information security, industry-specific guidelines, and NIS2 requirements. Control ensures traceability and thus provides a better foundation for audits, contracts, and risk reports.

Greater resilience to crises

Cyberattacks, technical failures, supply chain issues, or political restrictions can severely disrupt digital business processes. Companies with robust cloud architectures are better able to respond because they have alternatives, defined responsibilities, and recovery processes in place.

Greater capacity for innovation

Digital sovereignty does not hinder innovation. On the contrary: Those who understand dependencies and design flexible systems can implement new digital business models more quickly and securely. Sovereignty creates the framework within which innovation can take place in a controlled, scalable, and legally compliant manner.

Digital Sovereignty in the Workplace: The Risks of Ignorance

Digital dependencies do not disappear unless they are actively addressed. They simply become harder to manage. For executives and management, the risk is that operational IT decisions will gradually give rise to strategic dependencies.

Rising Costs Due to Dependence on Providers

Vendor lock-in can become a financial risk. When there are no alternatives, it is difficult to negotiate price adjustments, new licensing models, or rising operating costs. Companies then end up paying not only for the technology, but also for their lack of freedom to act.

Limited ability to act in the event of outages or access restrictions

In the absence of alternatives, outages or access restrictions can quickly lead to business interruptions. This is particularly critical when core applications, production processes, customer data, or communication systems are affected. Without contingency plans and recovery options, the risk of productivity losses increases.

Increased Data Privacy and Compliance Risk

Unclear data locations, complex chains of service providers, and insufficient control over access can contribute to legal uncertainty. The less transparent the cloud landscape is, the more difficult it becomes to properly meet data protection requirements, compliance obligations, and contractual responsibilities.

Weaker Information Security

A lack of transparency regarding systems, interfaces, and responsibilities increases cyber risks. As a result, companies cannot reliably determine which systems are critical, what dependencies exist, and how security incidents are coordinated. In light of NIS2 and professional risk management, this transparency is increasingly becoming a prerequisite for responsible corporate governance.

Reduced capacity for innovation due to complex IT landscapes

Proprietary siloed solutions, a lack of interoperability, and insufficient expertise are holding back new technologies. Each new integration becomes more complex, data remains trapped in silos, and digital projects take longer to complete. This weakens competitiveness.

Strategic Risk Due to a Lack of Awareness Among Management

A key obstacle is a lack of awareness at the executive level. Digital sovereignty requires knowledge, clear priorities, and a willingness to change. A shortage of skilled workers and limited resources do not make this issue any easier for SMEs. This makes it all the more important to take a realistic first step that prioritizes critical areas.

The Path to Greater Digital Sovereignty: How Companies Can Get Off to a Successful Start

Digital sovereignty is not achieved by simply switching providers once. It is a process that begins with transparency and is gradually implemented in strategy, architecture, governance, and operations.

1. Identify critical data, applications, and processes

Start by taking stock: Which data is particularly sensitive, subject to regulations, or business-critical? Which applications support core business processes? Which systems must not fail in the event of an emergency?

This prioritization helps ensure that resources and investments are allocated strategically. Not every application requires the same level of attention. However, critical systems should be clearly identified and protected.

2. Make dependencies and risks transparent

Identify dependencies on providers, data flows, contract terms, operating models, interfaces, exit options, and compliance risks. Questions such as the following are particularly important:

• Which providers operate business-critical services?
• Where is sensitive data located and how does it flow?
• What are the contract terms, notice periods, and export options?
• Which systems are proprietary or difficult to migrate?
• Which emergency and recovery processes are documented?

3. Develop a Roadmap for a Successful Cloud Strategy

Based on the assessment, a target vision can be developed. The key question here is which cloud models are right for your company: public cloud, private cloud, hybrid cloud, or multi-cloud.

The goal is not a one-size-fits-all solution, but rather an architecture that takes into account business objectives, regulatory requirements, security needs, cost-effectiveness, and existing expertise.

4. Take open standards and portability into account

Architectural decisions have a long-term impact on your ability to switch systems. Open standards, documented interfaces, and portable applications provide flexibility. Especially for new projects, it’s worth considering portability and interoperability early on, because making adjustments later can be significantly more expensive.

5. Develop Skills and Responsibilities

Digital sovereignty requires not only technology but also expertise. Companies should clarify who assesses risks, who prepares vendor decisions, who monitors security and compliance requirements, and who makes decisions in the event of an emergency.

Especially in the face of a shortage of skilled workers, it is important to build up internal knowledge in a targeted manner and to incorporate external expertise where it makes strategic sense. Management awareness is a crucial factor for success in this regard.

6. Regularly assess and further develop sovereignty

Digital sovereignty is not a static state. Providers, technologies, legal frameworks, and business requirements are constantly changing. Companies should therefore regularly assess their dependencies, identify emerging risks, and determine which courses of action can be improved.
