About us

The Security & Defence Agenda (SDA) is Brussels' only dedicated security and defence think-tank. The SDA raises awareness by anticipating the political agenda and focusing attention on European and transatlantic policy challenges related to security and defence. Its activities include roundtables, lunch and evening debates, policymakers’ dinners, international conferences and a range of publications. The SDA brings together experts and policymakers from the EU institutions, NATO, national governments, industry, the media, think-tanks, academia and NGOs. This diversity, and a reputation for thought-provoking debate, has kept the SDA at the heart of the defence and security community.
