This chapter explores digital resilience as a core pillar of digital sovereignty in the technopolar age, emphasizing its strategic, cognitive, and legal dimensions. Moving beyond traditional notions of cybersecurity and infrastructural robustness, digital resilience encompasses a state’s capacity to anticipate, absorb, and adapt to disruptions across technological, diplomatic, and informational domains. The chapter reframes classical resilience models through a cognitive lens, analyzing how AI-augmented diplomacy and interpretive agility shape sovereign agency. Drawing on national case studies such as Estonia, the EU, the U.S., China, and Türkiye, the chapter highlights best practices in cybersecurity, supply chain diversification, digital strategic autonomy, and societal resilience. It also examines how international legal norms, particularly under the UN Charter, are being reinterpreted to address cyber conflict and digital coercion. The concept of “weaponized interdependence” underscores how technological dependencies can be used for strategic leverage, making resilience a precondition for sovereign decision-making. Finally, the chapter explores how regional cooperation and public-private partnerships enable more adaptive, secure, and inclusive digital ecosystems. Resilience is not only a defensive imperative but a forward-looking capacity that ensures operational continuity, legal integrity, and national autonomy in an era of constant digital contestation.
