About Whalebone
Whalebone develops security products that work at the network level, so they do not need to be installed or updated on individual devices. The company sells to telecommunications operators, internet service providers, enterprises, public institutions, and governments. Its main offering is a protective DNS resolver that filters malicious traffic before it reaches users. This approach covers all connected devices, including phones and IoT equipment that are hard to secure with traditional software. The company also provides identity protection and fraud call protection as additional layers. Whalebone was founded in 2016 in Brno, Czech Republic. It leads the DNS4EU project, which aims to provide secure DNS resolution for the European Union. More than 300 telecom providers use its services. The company says its no-installation model leads to higher adoption rates and lower churn compared to conventional security tools.
