Data and Tech Sovereignty are crucial for businesses today to maintain control, security, and competitive advantage in an increasingly digital and regulated world. In this blog, find out the need-to-know information and the top expert speakers.
What is Data Sovereignty?
Data sovereignty is the principle that all data is subject to an individual country’s governance and laws from where the data is collected or stored. For example, in the UK, data must be in accordance with regulations such as the General Data Protection Regulation (GDPR). This results in laws around data differing depending on where the data comes from or is stored.

What is Tech Sovereignty?
Technology sovereignty is the ability not to excessively rely on foreign suppliers to design, develop. Operate and maintain critical technologies. This ensures that individual countries or regions can protect their digital infrastructure, data and innovation, therefore strengthening their national security and self-resilience.

Why are Data & Tech Sovereignty Important in the Digital Age?
In the digital age, data and technology sovereignty are vital because they enable nations and organisations to retain control over where data is stored, how it is processed, and who has access to it, thereby protecting privacy, security and strategic autonomy. According to a recent survey, 51% of UK organisations now regard data sovereignty as a crucial part of their data-management approach. By ensuring local governance and resilience of digital infrastructure, sovereignty helps guard against external dependencies and geopolitical risks.
How Does Data & Tech Sovereignty Affect Individuals, Businesses & Governments?
Data and tech sovereignty affect individuals, businesses and governments by shaping how data is managed, controlled and protected across all levels of society. For businesses in particular, a recent study found that 84% of companies view data sovereignty as a central strategic point, and 70 % reported its relevance has significantly increased over the past one to two years. Ensuring sovereign control over data helps organisations maintain compliance, build customer trust and reduce risks tied to regulation or foreign jurisdiction.
