The Global Cyber Summit will focus on collaboration. We face a level of geopolitical instability not witnessed for a generation or more. The international order on which we have relied since 1945 has gone, for better or for worse. What will replace it continues to take shape. Prudence suggests we prepare for the worst. Instability favours our adversaries, presenting organisations with complex challenges augmented by the emergence of new technologies. Collaboration and trusted relationships will be key to managing risks and navigating our organisations safely through the attendant threats.
