COPENHAGEN, Denmark, April 23, 2025 – Heimdal, a leading European cybersecurity company, today announced that it has been granted U.S. Patent No. 18333620 for a pioneering invention that calculates the probability of a domain being malicious. This milestone reinforces Heimdal’s position at the forefront of DNS security.
The patent, titled “Apparatus and Method of Predicting Malicious Domains,” grants Heimdal exclusive rights to a proprietary method that uses advanced algorithms to assess domain risk based on input data processed through a computer system.
Unleashing unlimited DNS security with AI
Heimdal’s Predictive DNS™ technology uses artificial intelligence to detect and block malicious domains. It combines machine learning, Natural Language Processing (NLP), and computer vision, powered by neural networks trained on millions of domain names, DNS records, and behavioral patterns.
This method evaluates the likelihood that a domain is malicious well before it can be used in phishing, command-and-control (C&C) activity, ransomware, or data exfiltration.
By identifying threats earlier, this approach significantly improves detection speed and accuracy, helping organizations strengthen their DNS security and stay ahead of evolving attacks.
Why DNS security matters more than ever?
DNS is a core part of how the internet functions, but it’s also one of the most exploited attack vectors.
In fact, 91% of malware, ransomware, and breach-related communications involve DNS. Yet many organizations overlook it as a frontline security layer.
Heimdal’s industry-first patent is strong proof of its unique capabilities in predictive protection and cybersecurity innovation.
With this technology, security teams can neutralize threats before they escalate, maintain compliance with data protection regulations, and reduce the risk of downtime and data loss.
I am proud to work with an organization of passionate individuals who strive to make a difference for the many customers relying on our platform and pioneering technology.
This tech patent will ensure that Heimdal operates at the frontline of DNS security for many years to come.
