Election Security

As more political activity touches the digital realm, there exists a real potential for these issues to influence voting, compromise election activities, and alter core democratic norms.


Our work is aimed at addressing key election cybersecurity issues, such as election official training, technical volunteer capacity building, social media disinformation campaigns, and robust post-election auditing.

CDT works to combat misinformation and disinformation, particularly as it impacts elections, targets marginalized communities, and engages in voter suppression.
