Development Challenge Governments are deploying digital public infrastructure, AI systems, and data-driven services at speed - but without adequate trust frameworks in place. Cybersecurity vulnerabilities, weak data governance, and deepening dependencies on foreign technology, talent, and cloud platforms expose countries to systemic risk. For developing economies, these challenges converge into a crisis of digital sovereignty: limited ability to govern data, regulate AI, build domestic capacity, or ensure the resilience of essential digital services. Retrofitting trust after deployment is costly and often ineffective. World Bank Group The WBG addresses digital trust through an integrated approach that brings cybersecurity, data protection, and responsible AI governance together as a cohesive function - ensuring these protections are built into digital systems from the start, not added as an afterthought once infrastructure is already in place. WBG's engagement spans three interconnected pillars. Foundations establish the legal and regulatory baseline through data protection laws, cybersecurity frameworks, and AI governance architecture, tied directly to government budget support agreements so that the right legal protections are in place before digital infrastructure is built. Capabilities strengthen enforcement institutions - Data Protection Authorities, national Computer Emergency Readiness Teams (CERTs), and cybersecurity bodies - while embedding data rights and digital safety into skills programs. Resilience prepares countries for inevitable incidents through contingency financing and pre-approved response mechanisms. A WBG-supported multistakeholder collaboration, spanning public, private, academic, and civil society organizations, produced the third edition of the Guide to Developing a National Cybersecurity Strategy, delivering streamlined, actionable guidance to help low- and middle-income countries build cybersecurity strategies aligned with national development priorities, with new emphasis on multi-year financing, governance accountability, and policy agility for emerging technologies including AI, IoT, and quantum. In partnership with peer multilateral development banks (MDBs) and international forums, WBG advocates for data governance frameworks reflecting developing economy realities. International
