SATIE was explicitly about securing air transport infrastructure across Europe, with Zagreb Airport as a participating operator.

Croatia's main international airport — operational testbed for aviation and critical infrastructure security research.
Their core work
Zagreb International Airport is Croatia's main international aviation gateway, responsible for operating complex airport infrastructure serving millions of passengers annually. In EU research, they participate not as a technology developer but as an end-user and real-world validation environment — bringing practitioner knowledge of how a functioning international airport actually manages physical security, access control, emergency response, and system interdependencies. Their contribution to consortia is the operator's perspective: they define requirements, validate proposed solutions against live infrastructure conditions, and stress-test technologies against the specific constraints of a major transport hub. They do not produce research outputs; they make research credible by grounding it in operational reality.
What they specialise in
PRAETORIAN addressed protection of critical infrastructures from advanced combined cyber and physical threats, where the airport represents a canonical critical infrastructure target.
PRAETORIAN keywords include combined physical and cyber threats, digital twin, cascading effects, and coordinated attack — all applied to their airport operational context.
PRAETORIAN lists situation awareness, first responder, and natural disaster as keywords, reflecting the airport's role in multi-agency incident management.
How they've shifted over time
Zagreb Airport's H2020 participation is short and recent (2019–2023), leaving no early-period baseline to compare against. Their first project, SATIE, was tightly scoped to aviation — securing the European air transport infrastructure specifically. Their second project, PRAETORIAN, broadened significantly: the airport moved into generalist critical infrastructure protection, engaging with cyber threats, digital twins, cascading failure scenarios, and coordinated attacks that apply well beyond aviation. This shift from sector-specific security to cross-sector critical infrastructure resilience is the clearest trend available in their limited data.
Zagreb Airport is expanding from aviation-specific security toward a broader critical infrastructure operator identity — making them an increasingly versatile end-user partner for consortia working on ports, rail, energy, or any infrastructure facing combined cyber and physical threats.
How they like to work
Zagreb Airport has participated exclusively as a consortium partner, never as a coordinator — consistent with an end-user role where the airport provides access, operational context, and validation rather than leading research design. Both projects were large Innovation Actions with the airport embedded in consortia spanning 11 countries and 39 distinct partners, indicating they are comfortable operating inside complex multi-partner structures. They contribute requirements and use cases; they do not drive technical work packages.
Across two projects, Zagreb Airport has connected with 39 unique consortium partners across 11 countries — a wide geographic spread for just two participations, reflecting the large pan-European consortia typical of Pillar 3 security projects. No single geography dominates, suggesting they fit into broad EU-wide security research networks rather than a tight regional cluster.
What sets them apart
Very few functioning international airports participate actively in EU research consortia, which makes Zagreb Airport rare: they offer something technology developers cannot provide — a live, regulated, high-stakes operational environment for validating security solutions. Their willingness to engage in Innovation Actions signals openness to testing new technologies against real airport conditions. For any consortium that needs an aviation or transport infrastructure end-user to satisfy reviewers and satisfy real-world applicability requirements, Zagreb Airport fills that slot with credibility.
Highlights from their portfolio
- SATIEThe largest project by EC funding (EUR 177,625) and the most direct fit with their core identity — a pan-European effort to secure air transport infrastructure where an operating airport is an essential, not supplementary, partner.
- PRAETORIANDemonstrates the airport's ability to step into broader critical infrastructure research beyond aviation, engaging with digital twin methodologies and combined cyber-physical threat modelling.
