Public procurement refers to processes through which national, regional, and local public authorities, state-owned enterprises, or other related bodies governed by public law, purchase products, services, and public work. Such purchases have been a particularly important element in developing the Internal Market of the European Union (EU). Given recent procurement reforms in the EU, including the 2009 reform on defense procurement, this paper examines public cyber security procurement in Europe. Two questions are examined: (1) whether cyber security procurement differs from public procurement in general, and (2) whether there are any noteworthy signs of Europeanization in terms of cyber security procurement. According to the empirical results, cyber security procurement tends to differ from general public procurement. In particular, competition obstacles are visible in terms of bids for cyber security procurement tenders. This result is accompanied with a visible lack of Europeanization, although the same observation generalizes to public procurement in the EU generally. With these results and the accompanying discussion, the paper contributes to the recent lively discussion about European security and its relation to marketization.
