This paper examines how new security technologies could reshape Bulgaria’s critical infrastructure resilience while simultaneously creating new vulnerabilities and dependencies. Bulgaria’s modernization, pursued through EU and NATO frameworks and supported by initiatives such as the Defense Innovation Center, promises stronger protection against evolving threats. Yet these same pathways embed risks, from reliance on external vendors and standards to design-level weaknesses such as expanded cyber attack surfaces and system complexity. Adopting a prospective, scenario-oriented approach, the paper argues that resilience and dependency develop in parallel, and that anticipating this paradox will be essential for shaping Bulgaria’s future security strategy.

This paper examines the prospective role of Bulgaria’s newly established Defense Innovation Center at Sofia Tech Park in strengthening critical infrastructure resilience. Designed in line with NATO and EU standards, the Center is expected to test emerging technologies and develop prototypes, with an initial focus on unmanned aerial vehicles (UAVs) and advanced defense systems. The analysis adopts a conceptual approach, outlining potential applications of these dual-use technologies across the energy, communications, cyber, and transport sectors. It also highlights key risks, including funding sustainability, dual-use dilemmas, and continued dependence on external technological ecosystems. By situating the initiative within the broader NATO and EU innovation landscape, the paper underscores both the opportunities and uncertainties of integrating defense-driven innovation into national resilience strategies.

Without claiming to be exhaustive, this paper aims at analyzing the tools of alternative (Track II and III diplomacy) for conflict resolution and crisis management. In order to maximize the gains from private diplomacy, the EU should take into account what Track II and III diplomacy has done so far to help solve conflicts, why it is need and how it can best be used.
