Digital Security and Human Rights Defenders in the Asia-Pacific assesses the adoption of digital security tools and measures by changemakers in the region to address online threats that they currently face amid increasing state surveillance. The report highlights the various ways in which changemakers in the region have adopted to the threats: they are evaluating the security of their online infrastructure, increasing ownership of these infrastructures, and adopting secure software and work flows. Nonetheless, changemakers face varying obstacles in adopting online security measures, including complexity of the tools, limited adoption of these measures in the wider sector, cultural/language barriers and technical, financial and human resource constraints. The report concludes with a set of recommendations for changemakers, INGOs, donors, and technology companies to address key challenges that limit the effective implementation of digital security tools and protocols. It points to the need of a multi-stakeholder approach to address digital threats faced by changemakers.
