It provides millions of internet users with seamless digital life protection, keeping them secure against malware, phishing, ransomware, and other malicious digital attacks – without the need to download anything.
The European Commission has recognized Whalebone’s exceptional capabilities by appointing it the Consortium Leader for the European Union’s DNS4EU project. As the sole developer and operator of the official DNS resolver for the EU, in collaboration with a consortium of 13 members from 10 countries, European governments and enterprises can leverage Whalebone's expertise in securing DNS servers to protect against digital threats.
The success of Whalebone Aura among global T1 telco providers validates the company’s ability to deliver robust DNS security that is effective, user-friendly, and brings value to their business. Whalebone’s products also include Peacemaker (for regional ISPs), Immunity (for enterprises), and DNS4GOV (for government/public sectors), all of which have proven instrumental in defending against threats to global DNS.
