The Civil Society Information Society Advisory Council (CSISAC) is the "voice of civil society" at the OECD. CSISAC's mission is set out in the Seoul Declaration. CSISAC contributes to the OECD’s work on Digital Economy Policy and promotes the exchange of information between the OECD and civil society. The OECD provides civil society participants with substantial empirical analysis that enable informed policy assessments; CSISAC provides the OECD with the essential perspectives of experts and NGOs leaders. CSISAC strengthens the relationship between civil society and the OECD and promotes better-informed and more widely accepted policies for the IT sector.

Support for CSISAC has been received from the Open Society Institute, the Markle Foundation, the EPIC Public Voice Project, and other donors.
