About Whalebone
At a glance
Whalebone is a cybersecurity company specializing in Network Security, founded in 2016 and headquartered in Brno, Czech Republic. It has raised $17.6M in total funding, employs about 400 people, and is privately held.
Whalebone is a cybersecurity company that delivers DNS-based security solutions to telecommunications operators, internet service providers (ISPs), enterprises, and public institutions. The company offers three primary product lines: Whalebone Aura, Whalebone Immunity, and Whalebone Peacemaker. Whalebone Aura is designed for telco operators and enables them to offer cybersecurity services to their consumer (B2C), small business (B2B), and government (B2G) customers. It requires no installation or software updates on end-user devices, operating at the network/DNS level. Aura includes multiple security layers: DNS Security, Identity Protection, and Fraud Call Protection. Whalebone Immunity targets enterprises and public institutions — including critical infrastructure, educational institutions, financial services, government bodies, and municipalities. It functions as a DNS security layer that blocks access to malicious domains before threats reach end users, complementing existing firewall and endpoint security tools. Whalebone Peacemaker is aimed at ISPs, helping them reduce user-generated support issues and generate additional revenue through network-level security offerings. All products rely on real-time threat intelligence rather than periodic signature updates, enabling immediate blocking of newly identified malicious domains. The company also leads the DNS4EU project, a European Union initiative to provide secure and private DNS resolution for EU institutions, governments, and citizens, targeting coverage of up to 100 million users. Whalebone reports over 300 telecommunications providers using its services globally.
