DNS4EU is a European Union initiative aimed at strengthening digital sovereignty and cybersecurity. Unlike foreign DNS services that often lack GDPR compliance and transparency, DNS4EU ensures that DNS data stays within the EU’s legal and geographic boundaries. This whitepaper outlines DNS4EU’s core benefits, including secure DNS resolution, threat blocking capabilities, and compliance with European data protection standards. We explore its technical strengths, deployment opportunities, and the strategic role it can play in enterprise and government networks.
