The purpose of this briefing is to report on the key observations from the EvoCS Regional Workshop for North Western Europe. The insights emerging from this EvoCS regional workshop have provided a sense of the complex interconnectivity of the debates that have shaped/are shaping the security discourse, as well as the disconnected dimensions that could be considered under this nebulous and politically charged term. The workshop allowed for corroboration and/or re-calibration of the EvoCS coding analysis, informing the coding with expert opinion from a cross-section of policy makers, academics and practitioners. This approach aimed to overcome the cross-sectional nature of the dataset, revealing something of the provenance of the concept of security and its constituent components from a variety of stakeholder perspectives.
