How is diplomacy evolving as Cyberspace becomes central to national defense and global security? José Manuel Barroso, President of the European Commission (2004-2014) and Prime Minister of Portugal (2002-2004), shares his perspective on how cyber capabilities are reshaping geopolitics and international relations.

Drawing on decades of experience at the highest levels of global governance, he explores the growing asymmetry between nations’ cyber capabilities, the integration of cybersecurity into defense and diplomatic strategy, and how developing nations can strengthen their competitiveness and influence in an increasingly interconnected world.

From cyber diplomacy and public-private cooperation to the idea of cybersecurity as a global public good, Barroso reflects on why cooperation remains essential in an evolving geopolitical landscape, and underscores the importance of coordinated action between governments, industry, and civil society to address shared cyber risks.
