Digital technologies are a vital resource for Human Rights Defenders (HRDs) and civic actors around the world. However, these technologies can also be misused to target HRDs for repression and to undermine civic space. To address this, the United States is releasing new guidance that sets out best practices and actions online platforms can take to implement more robust support for HRDs under threat. This guidance builds on 10 recommendations jointly released by the United States and European Union on March 11 for online platforms to more effectively identify, mitigate, and provide access to remedy for digital attacks targeting HRDs.
