This Milestone assesses selected, currently operational systems delivering Remote Desktop Access to sensitive data for social sciences and humanities. Prior to selection, criteria were established in three domains: technical, legal, and organizational/administrative. A significant consistency was found across the systems, and this is grounds for cautious optimism that “scaling up” from these systems may be possible. However, several factors contribute to the need to accommodate a solution with substantial flexibility. Recommendations will be provided in SSHOC D5.10 White Paper on Remote Access to Sensitive Data in the Social Sciences and Humanities: 2021 and beyond.
