In October 2020, the European Union followed in the footsteps of the United States and imposed its cyber sanctions for the very first time. These are one of the instruments available in the Union’s cyber diplomacy toolbox and are specifically designed ‘to prevent, discourage, deter and respond to continuing and increasing malicious behaviour in cyberspace’. While representing an important step forward for the Union’s commitment to uphold a ‘rules-based order’ in cyberspace as a single voice, the adoption of cyber sanctions raises however questions on their effectiveness and their broader strategic function. Addressing these two aspects, this panel debate thus aims 1) to shed light on the current developments on cyber sanctions within the EU; 2) to interrogate their effectiveness as legal instruments; and 3) to explore how they intersect with the EU’s broader strategic and geopolitical role as normative power in cyberspace.
