Why sovereignty is crucial for real digital trust

Written by Peter Amrhyn | 10/30/26, 3:27 PM

Is digital sovereignty only a matter for policymakers? Not really; for any organization that signs, seals, or certifies online, the lack of it can become a business risk.

In today's digital business environment, questions like the following arise on a daily basis: Is this email genuine? Did the person named on this contract really sign it? Can we prove this log entry has not been altered? A profound answer usually relies on certificates, electronic signatures, seals, and timestamps, provided by trust service providers (TSPs). Buying such services is not a big deal, but in 2026 businesses must look behind the curtain and ask: who is the organization behind the trust services, and who ultimately controls the assets?

From policy to procurement requirements

What actually is digital sovereignty? Usually, it is defined as the ability to make independent decisions about digital infrastructure, technology, data, and services. This is not just about server location. It is about who can access, control, and legally influence data and digital infrastructure across the whole digital value chain. On the other hand, sovereignty in the digital context does not mean isolation or full self-sufficiency. It is more about reducing critical dependencies and staying resilient when geopolitical or economic conditions shift. This shift is no longer abstract; it is now reality. Thus, the EU has been putting strong emphasis on the practical implementation of sovereign infrastructure in the past months:

  • April 2026: The European Commission awarded a 180 million Euro contract for sovereign cloud services for EU institutions. Its Cloud Sovereignty Framework scores providers on legal and jurisdictional independence, supply chains, technology and security.

  • 3 June 2026: The Commission presented its Technological Sovereignty Package, covering semiconductors, cloud and AI, open source and the digitalization of the energy system.

  • Until 15 September 2026: A targeted consultation on EU data sovereignty examined the risks of third-country access to sensitive information.


Two sides of the same coin

Sovereignty gives you control over digital systems; trust decides whether anyone is willing to rely on them. Sovereignty asks who controls the infrastructure, where data is processed and which laws apply. Trust asks whether users, businesses and governments can count on those systems being reliable, transparent and accountable. Dependency is where the two collide: If critical services run on infrastructure controlled outside Europe, questions about jurisdiction, data access and supply-chain disruption follow. Those questions erode trust, no matter how advanced the technology is. Sovereignty alone does not create trust. A European provider is not trustworthy simply because it is European. It still has to prove strong security, transparent operations, and regulatory compliance through certification, audits, and clear liability rules.

The relationship works as a cycle. Sovereignty creates the conditions for trust, and trust makes sovereign infrastructure usable and sustainable. Resilience ties the two together: a service you control and can verify is one that keeps running when conditions change.


Trust is only as sovereign as its foundation

Certificates, signatures, and seals together build the technical form of digital trust. If they are not sovereign and resilient, trusted transactions are at risk. It is because of this that in the EU and Switzerland trust service providers face clear rules, mandatory audits and defined liability. With providers from other jurisdictions, companies cannot always be sure how fully European requirements are met or whether foreign governments might want to interfere. Sovereignty therefore gains a legal dimension. Every organization that depends on electronic signatures, seals or certificates should be well aware of the possible consequences of non-sovereign infrastructures.

The safest way is to work with a qualified provider that is certified and audited under European law, keeps its keys and infrastructure within its customers' jurisdiction, and can lay open its supply chain. That is how trust stays intact when the geopolitical climate changes. One such provider is Swisscom Trust Services, which is certified under both eIDAS and the Swiss ZertES, operates georedundant data centers, and sources hardware security modules from European vendors. Through its eIDAS certification in Austria, its trust service is directly subject to European law.
