The year 2021 began with cautious but genuine optimism in much of the world, buoyed by the twin effects of a new U.S. administration, and the hope that, with new vaccines, the COVID-19 pandemic would soon end.

People across the globe have never been more digitally connected than now. While that connectivity enables amazing new technological capabilities, it also constantly creates new vulnerabilities.
