Elections influenced by fake news on social media, manipulation of purchasing decisions by global organisations, outdated consumer protection, a loss of trust coupled with the ongoing digitalisation of all areas of politics, daily life and the economy, alongside increasingly sophisticated, large-scale and automated attacks at ever-lower costs, are leading to the erosion of democracy. In the face of hybrid threats and the intertwined interests of state- and commercially-driven cyberattacks, the dividing line between internal and external security is becoming blurred. In the borderless digital space, not only crime and competition but also conflicts and wars are being waged. To strengthen democracy, many protective measures have been introduced: legislation, the strengthening of digital infrastructure, the bolstering of critical organisations, awareness-raising, and cooperation between governments, businesses and civil society. Not all measures are proving effective. Who needs to take what action to ensure that the resilience of German and European democracy in the digital realm is on a par with that in the analogue world?
