At the same time that cyberspace has created some opportunities, such as higher efficiency of critical infrastructures and a lower barrier cost venue for non-state actors to project their ideas and voices, the securitisation of the digital domain happens. Society’s collective imaginary has already created some catastrophic scenario projections directed to states and military manoeuvres. Besides, recent geopolitical movements related to emerging technologies, have rekindled ideas towards power in cyberspace. These developments increase concerns about instability in cyberspace and deserve some consideration and more in-depth debate.Thus, aiming to promote an in-depth debate about security in cyberspace, the online workshop “Security in Cyberspace: dynamics, limits, and opportunities” – held by the Alexander von Humboldt Institute for Internet and Society (HIIG), Getulio Vargas Foundation (FGV Direito SP) and the Federal Universities of Santa Catarina (UFSC) and Rio Grande do Sul (UFRGS), – encompassed four main topics: (1) cyberspace as a war domain, (2) liberty vs security in cyberspace, (3) the cyber institutional and organisational apparatus of European and Brazilian states and (4) the changes, or the lack thereof, as a consequence of the international balance of power entrenched in the digital sphere. Seeking also to demystify, with the presentations of Brazilian and European scholars, the perception that cyber problems are constrained to a very few “great powers” like China, Russia, and the USA.
