Digital sovereignty.starts with the infrastructure.

What digital sovereignty really means

Digital sovereignty means being able to make technical and organisational decisions about data, systems and dependencies yourself. This includes more than one server location in Europe. Operators, jurisdiction, administrative access, subcontractors, encryption, key control and the ability to re-export data and applications are also crucial.

An organisation is therefore not automatically sovereign just because a cloud region is labeled “Europe”. She must be able to understand where data is processed, which companies have access, which legal systems apply and how she can change providers.

Why AI video analytics has special requirements

AI video analytics processes video streams, images, events and metadata depending on the use case. People, vehicles, licence plates or other personal information can be identified on it. Technical configurations, user accounts, protocols and alarm histories are also created.

Therefore, it is not enough to just look at the storage location of recorded videos. Preview images, backups, support access, telemetry and model metadata are also included in data flow analysis. The more precisely these paths are documented, the more reliably data protection, information security and operations can be organized.

Data location is important, but not sufficient

The physical location initially only answers one question: In which data centre does data lie or originate? However, for a sovereign architecture, additional levels must be added.

• Operator: Which company operates the platform and infrastructure?
• Legal area: What legal obligations is the provider subject to?
• Accesses: Who can have administrative access to systems, backups or keys?
• Subcontractor: Which other companies are technically involved?
• Data paths: Through which networks, regions and services does information flow?
• Exit: Can data, configurations and interfaces be migrated in a controlled manner?

Only the interaction of these points creates demonstrable control. A European storage location can make sense, but it does not replace checking the contract, group structure and actual operating channels.

Schrems II and international data transfers

In 2020, the European Court of Justice declared the then EU-US Privacy Shield invalid in judgment C-311/18, known as Schrems II. At the same time, standard contractual clauses generally remained a permissible transfer instrument. However, those responsible must check whether the level of protection can actually be guaranteed in the specific recipient country.

The European Data Protection Board recommends a structured review of the transfers and, if necessary, additional technical, contractual or organisational measures. This can include strong encryption, controlled keys, pseudonymization and narrow access.

What has changed with the EU-US Data Privacy Framework

There has been a new adequacy decision for the EU-US Data Privacy Framework since July 2023. This allows personal data to be transferred to participating and certified US companies. However, this does not mean that every use of a US service is automatically covered.

Those responsible must continue to check which provider, which specific service and which recipients are involved. If a recipient is not part of the framework, other instruments such as standard contractual clauses and additional measures may be considered. Therefore, a contribution to digital sovereignty should neither give a blanket all-clear nor blanketly portray every US cloud as inadmissible.

What the CLOUD Act means for provider choice

The US CLOUD Act clarifies that providers under US jurisdiction may, under certain conditions, be required to release electronic data in their possession, custody or control. The physical location alone does not therefore resolve this jurisdictional issue.

This does not mean that authorities can access any European cloud at will. Nevertheless, the operating jurisdiction is a risk factor in its own right that must be evaluated alongside storage location, encryption and contracts. A robust decision documents these factors rather than relying solely on the label of a region.

Switzerland in the European data protection framework

The European Commission confirmed in 2024 that Switzerland continues to provide an adequate level of data protection for personal data transferred from the EU. This means that data transfers from the EU to Switzerland can in principle be based on this adequacy decision.

Nevertheless, each person responsible remains responsible for the purpose, necessity, security and transparency of their processing. Even a data centre in Switzerland does not automatically make a specific deployment legally compliant. Data minimization, access control and traceable deletion remain necessary.

How to build a confident Visual AI architecture

Digital sovereignty begins with the architectural decision. Depending on the risk and operating model, analysis can occur at the edge, on a local server, in a private cloud or in a hybrid environment. The most technically convenient model should not automatically win, but rather the model that best combines the need for protection and the process.

Seven building blocks for verifiable control

1. Data inventory: Collect video streams, images, events, metadata and logs.
2. Data flow plan: Document sources, connections, storage locations and recipients.
3. Role model: Limit rights by task and review them regularly.
4. Encryption: Plan transport, storage and key management separately.
5. Storage: Set deadlines for each data type and technically enforce deletion.
6. Operating records: Log access, changes, updates and incidents.
7. Exit plan: Clarify export, migration and controlled termination before signing the contract.

Edge, on-premise, private cloud or hybrid?

Edge analysis processes data close to the camera and can reduce transmissions. On-premise systems give organisations a lot of direct control, but require in-house expertise for updates, security and availability. A private cloud can combine centralized scaling with clearly defined data locations.

Hybrid models distribute tasks in a targeted manner. For example, video analytics can run locally while only reduced event metadata is processed centrally. Therefore, no one delivery model is inherently more sovereign than all others. What is crucial is whether data paths, responsibilities and dependencies match the protection needs.

How Synaedge implements data sovereignty

Synaedge plans Visual AI systems as edge, on-premise, cloud or hybrid architecture. This allows deployment to be tailored to privacy, performance, integration and operational responsibility. The technical basis allows operation independent of hyperscalers. Where data is actually processed and who gets access is agreed for each project.

A European infrastructure is no substitute for governance. That’s why network segmentation, minimum rights, multi-factor authentication, audit protocols, monitoring and regulated storage are part of the technical concept. Our page describes more about this Cybersecurity and Data Sovereignty.

What questions companies should ask before making a selection

A provider audit should produce concrete answers. Marketing terms alone are not enough. Those responsible should clarify at least the following questions in writing:

• Where is primary data, metadata, backups and logs processed?
• Which legal entities and subcontractors are involved?
• Who has administrative rights and who controls the keys?
• Which data leaves the defined legal area?
• How is support access shared and logged?
• What deadlines and deletion mechanisms apply?
• How does changing provider work without losing data and configurations?

Conclusion: Sovereignty is an architectural property

Digital sovereignty does not come from a single certificate or location sticker. It arises when an organisation knows its data paths, controls access, evaluates dependencies and can choose between suitable operating models.

This control is particularly important for AI video analytics because sensitive image data, events and operational processes come together. A European controlled infrastructure can reduce risks and complexity. However, legal compliance only arises through the combination of architecture, governance, contracts and a clearly documented purpose.

For operations in the EU, the GDPR and the relevant national regulations must be checked. In the case of police authorities, special data protection law can be decisive for criminal prosecution. Swiss requirements should also be viewed as a separate legal framework. Event-based processing is not automatically anonymous. Our article provides a current overview Data protection and EU AI Act.
