Abstract In the era of digital globalization, cross-border data flows have become essential for economic growth, innovation and international collaboration. However, the growing concerns about privacy, cybersecurity and state control have intensified national efforts to assert data sovereignty through restrictive policies like data localization. This research investigates the tension between national security imperatives, data sovereignty and the benefits of global data interoperability.
While data sovereignty helps in protecting privacy, infrastructure and state interests, the research found that rigid data localization can fragment the internet and hinder global innovation. Key drivers and challenges in data sovereignty include national security and law enforcement, privacy and data protection, strategic economic resource and cybersecurity. Comparative legal and regulatory frameworks analyses revealed that flexible systems such as the GDPR’s adequacy model or the US Cloud Act’s bilateral mechanisms provide more adaptive paths than unilateral restrictions. Additionally, the research study showed that encryption, federated learning and data classification tools can significantly reduce cross-border data risks.
To balance national security and global interoperability in cross-border data flows, international cooperation and agreements, harmonisation of legal standards and addressing legitimate security needs offer a diplomatic path towards convergence. The study concluded that a balanced model which is anchored in trust, transparency and accountability is feasible and necessary. Such a model should integrate legal, technical and cooperative tools to secure national interests while preserving the benefits of an open and interconnected digital economy.
