The European Centre of Excellence for Countering Hybrid Threats, commonly shortened to Hybrid CoE, is an autonomous international organisation based in Helsinki, Finland. It was established in 2017 following a memorandum of understanding signed by an initial group of nine states, and operates on the basis of a network linking the European Union and NATO with participating states.
Hybrid CoE's mandate is to strengthen participating states' civil-military capabilities, resilience, and preparedness to counter hybrid threats — coordinated and synchronised actions that deliberately target democratic states' and institutions' systemic vulnerabilities through a wide range of means (political, economic, military, civil, and informational). Typical subject areas include disinformation, election interference, cyber operations, economic coercion, weaponised migration, and sabotage of critical infrastructure.
The Centre is structured around several Communities of Interest, which have included Hybrid Influence, Vulnerabilities and Resilience, and Strategy and Defence. It produces research papers, trend analyses, and scenario-based exercises (notably tabletop exercises bringing together EU and NATO officials), and hosts training events for practitioners from member states.
Membership is open to EU member states and NATO Allies. The Centre has expanded steadily since its founding, growing to include the large majority of EU and NATO members. The United States, United Kingdom, Germany, France, and the Nordic states were among the early participants. Its Steering Board includes representatives of the EU's External Action Service and NATO's International Staff, reflecting its bridging role between the two organisations.
Hybrid CoE does not have operational or intelligence functions; it is a knowledge hub rather than a command. Its outputs are typically used to inform national policy, EU Hybrid Toolbox measures, and NATO's counter-hybrid posture, which was reinforced after Russia's 2014 annexation of Crimea and again after the 2022 full-scale invasion of Ukraine. Analysts often cite Hybrid CoE's working definition of hybrid threats as a reference point in academic and policy literature.
Example
In 2022, Hybrid CoE expanded its membership and stepped up tabletop exercises with EU and NATO officials in response to Russia's invasion of Ukraine and related hybrid activities across Europe.
