With the increase in proficiency and *creativity* of hackers, enabled by AI tools, cybersecurity has become a major topic of discussion worldwide. The EU's [NIS2 Directive](https://digital-strategy.ec.europa.eu/en/policies/nis2-directive?ref=therecursive.com) now binds **more than 160,000 entities to mandatory cyber obligations**, with fines of up to €10 million or 2% of global turnover, while the [European Union Agency for Cybersecurity (ENISA) logged 4,875 incidents](https://www.enisa.europa.eu/publications/enisa-threat-landscape-2025?ref=therecursive.com) across the bloc in June 2024 - June 2025\. The market is racing to keep up: [European cybersecurity spend](https://www.marketsandmarkets.com/Market-Reports/europe-cybersecurity-market-156644743.html?ref=therecursive.com) is set to climb from $54.8 billion in 2025 to $83.1 billion by 2030, and [**global venture funding**](https://www.securityweek.com/cybersecurity-firms-secured-14-billion-in-funding-in-2025/?ref=therecursive.com) into the sector hit nearly $14 billion in 2025 — its strongest year since 2021.

Central & Eastern Europe is quietly cashing in. Deep technical talent, lower burn rates, and a regulatory tailwind from the EU have turned the region into one of Europe's most prolific cybersecurity production lines: from post-quantum authentication in **Prague** and behavioral fraud AI in **Brno**, to identity verification in **Sofia**, supply-chain security in **Zagreb**, and offensive tooling in **Bucharest**. 

To have a better view of the CEE’s cybersecurity players, consult the list below.
