Europe is at the center of global digital transformation  from fintech in London and Berlin to advanced manufacturing in Germany and energy innovation across the Nordics. But as digital adoption accelerates, so do cyber risks. From ransomware attacks on healthcare systems to espionage targeting critical infrastructure, Europe’s cyber threat landscape is evolving rapidly.
