Developed within a European consortium with the support of ENISA and national CERTs, DNS4EU is now fully operational and publicly available. It is the first EU-backed resolver to offer a secure, transparent, and privacy-focused alternative to services like Google and Cloudflare.

DNS4EU includes several components: a public resolver; DNS4GOV, a commercial-grade service for governments and critical infrastructure; and a threat intelligence sharing network that supports the adoption of secure DNS and cross-border cybersecurity coordination.

The launch highlights the Czech Republic's growing role in European cybersecurity. With its hub in Brno, the region boasts a vibrant community of cybersecurity companies and a collaborative environment with global impact. Key institutions such as Masaryk University and Brno University of Technology lead major European cybersecurity projects (QARC and CCAT), underscoring the region's expertise in cryptography and quantum security certification. Both universities are also founding members of CyberSecurityHubCZ, a national center of excellence that fosters cross-sector collaboration.

According to a recent JIC report, cybersecurity is the most dynamic technology sector in the region in terms of venture capital investment. In early 2025 alone, local companies secured nearly €40 million, including funding rounds for Whalebone, Threatmark, and Safetica. This adds to Brno's strong track record of cybersecurity companies becoming international players, including the acquisition of Runecast for $28.4 million and the sale of Flowmon Networks. The city was also the birthplace of AVG Technologies, the Czech Republic's first unicorn, acquired by Avast in 2016 and now operating globally as Gen.

"Brno's success in cybersecurity is based on thorough research, exceptional talent, and strategic support for startups," said Petr Chládek, CEO of the innovation agency JIC. "DNS4EU demonstrates that the region can achieve digital sovereignty on a European scale."
