About the Czechia web market
Czechia is one of Central Europe's most digitally advanced economies, with internet penetration approaching 85% of the population. The country boasts a robust IT sector, with Prague serving as a leading European hub for software development, cybersecurity, and tech startups. Global companies including IBM, Red Hat, and Avast have significant operations in the country, and the local startup ecosystem has produced notable successes in cybersecurity and SaaS. High-speed fiber and mobile broadband networks cover the majority of the population, with ongoing investment in rural connectivity.
The .cz ccTLD, managed by CZ.NIC, is one of the most actively maintained and technically innovative domain registries in Europe. CZ.NIC has been a pioneer in DNSSEC adoption and open-source DNS software development, contributing tools widely used internationally. The registry operates the Turris router project, a widely deployed security-focused home router. Czech businesses show strong preference for .cz domains, and the registry maintains millions of active registrations. E-commerce, digital media, and cloud services sectors are particularly dynamic, driving consistent growth in domain registrations and hosted services.
