Slovakia became an independent country in 1993, joined the EU in 2004 and uses the euro. ESET has grown into one of Europe’s largest privately held cybersecurity companies, but its headquarters never moved: it still sits in Bratislava, under EU law and EU data-protection rules.

Development happens across a network of R&D centers — including Bratislava, Prague, Kraków, Montreal and Singapore. None of them is in Russia.
