We spoke with the COcyber Batch #3 Ambassadors to reflect on their journey and gather their insights on Europe’s cybersecurity future. Christos Xenakis brings long-standing expertise in cybersecurity education, research, and competitive cybersecurity, and values the ambassadorship for supporting knowledge exchange, awareness raising, and stronger links between civilian and defence communities.

The third cohort of COcyber Ambassadors brings together seven cybersecurity professionals whose combined expertise supports Europe’s efforts to improve cooperation between civilian and defence communities, strengthen digital resilience, and encourage practical knowledge-sharing across diverse security domains.
