Cloud-based communication tools have become a core part of how organisations operate. Platforms for messaging, file sharing, and video conferencing now underpin daily business workflows, supporting everything from internal collaboration to customer engagement. Remote and hybrid working have accelerated this shift, and for most organisations these tools are no longer optional.
At the same time, organisations are paying closer attention to how and where their data is processed. Questions around jurisdiction, control, and compliance used to be directed mainly at storage systems and databases. Now they apply equally to real-time communication tools.
This post looks at what sovereignty means in the context of video conferencing: why jurisdiction matters, how sovereign cloud differs from simpler concepts like data residency, and what to ask a provider before you sign up.
Table of contents
The term 'sovereign cloud' refers to a cloud computing environment where data is subject only to the laws and governance frameworks of a specific country or region, typically where the data is processed and controlled.
A practical definition generally includes four core elements:
Sovereignty goes beyond where servers are physically located. True sovereignty requires alignment across infrastructure, ownership, and legal control. Without all three, organisations may still face external legal risks.
These two terms are often used interchangeably, but they mean different things. Data residency means that data is stored in a specific location. It does not guarantee who can access the data or under which laws. For example, data stored in an EU data centre operated by a foreign provider may still be subject to non-EU legislation.
Many providers offer 'EU region' hosting, which typically means that data sits on servers located within Europe. But that alone is not enough.
The provider may still be headquartered outside the EU, meaning its global corporate structure could expose it to legal obligations that extend beyond European regulatory frameworks. As a result, the provider may need to comply with legal requests or disclosure requirements from non-EU authorities, and data could potentially be accessed under a foreign jurisdiction.
A simple comparison makes the difference clear:

This distinction matters for organisations that need to comply with European data protection requirements. EU regulations such as the GDPR place strict obligations on how personal data is processed, transferred, and accessed. Relying on data residency alone, without ensuring full sovereignty, can still leave an organisation exposed to foreign legal frameworks that conflict with those requirements. That can undermine key GDPR principles such as lawful processing, data minimisation, and protection against unauthorised access.
Legal jurisdiction is one of the most important aspects of sovereignty, and one of the most commonly overlooked.
The US CLOUD Act allows US-based companies to hand over data to US authorities even when that data is stored outside the United States. So data sitting in a European data centre may still be accessible under foreign law if the provider is a US-headquartered company. The Schrems II judgment (Court of Justice of the European Union, 2020) reinforced this concern, ruling that standard contractual clauses alone are not sufficient where a provider is subject to surveillance laws that conflict with EU data protection standards.
A few implications follow:
For organisations in healthcare, education, and public administration, these issues are especially important. ENISA has noted that healthcare providers in particular face significant risks when cloud services are operated by entities subject to extraterritorial laws (ENISA, 2021). These sectors handle health records, student information, and citizen data, all of which carry strict legal and ethical obligations around confidentiality and accountability, often with national or sector-specific rules on top of GDPR. Any uncertainty around jurisdiction or data access can introduce serious compliance risks and erode trust in the services they provide.
Video conferencing platforms present different challenges compared to traditional cloud services because they process data continuously and in real time.
Live communication streams are transmitted, processed, and sometimes routed across multiple nodes simultaneously. Unlike a file sitting in storage, audio and video data is in constant motion, which makes it essential to understand where processing occurs and under which jurisdiction.
Video platforms also generate a significant amount of metadata alongside the media streams: participant identities, join and leave times, and device and network information. In regulated environments, this metadata can be just as sensitive as the content of the calls themselves.
Many platforms also offer recordings, automated transcripts, and chat logs. These create persistent data that must be stored, managed, and protected in line with applicable regulations, adding another layer of compliance responsibility.
Modern platforms often integrate with third-party services or support live streaming, which can introduce additional data flows and extend the number of systems touching your data.
Compared to static data storage, video conferencing raises the sovereignty stakes: data is processed dynamically rather than simply stored, multiple data types are involved simultaneously, and external integrations can spread data flows beyond the primary platform. Evaluating where data is stored is not enough. You also need to understand how it is handled throughout its lifecycle.
When assessing a provider, these questions will help you get past the marketing and into the detail:
In practice, sovereign video conferencing means that real-time communication data is processed within a defined jurisdiction, the infrastructure is run by entities subject to that jurisdiction, and data flows are predictable and transparent. Organisations also retain control over optional features such as recordings and integrations.
This aligns with the core principles of data protection: minimisation, accountability, and control. It also reflects growing demand for digital infrastructure that meets regulatory requirements without sacrificing functionality.
Digital Samba is built around European data protection and operational control. The following aspects of the platform's architecture are relevant for organisations assessing sovereignty.
For organisations that handle sensitive data, sovereignty in video conferencing is not an abstract concern. Live communication generates real-time streams, metadata, and potentially persistent records, all processed under whatever legal framework governs the provider. Understanding which jurisdiction applies, who controls the infrastructure, and how data flows through the platform is the only way to make an informed decision about whether a provider actually meets your compliance requirements.
