This paper examines the issue of Russian disinformation in Estonia and how the country has built resilience against this threat. Drawing upon existing literature and a series of interviews conducted with Estonians of a variety of professional backgrounds, this work explores Estonia's whole-of-society approach to resilience and examines its incorporation of national security strategy, inter-institutional cooperation, and media literacy education. Ultimately, this paper argues that Estonia's efforts have been largely successful in enabling the country to strengthen its society against Russian disinformation and offers key takeaways for other countries such as the United States.
