Practical Usage

Accelerate threat detection and response

Stay one step ahead by analyzing DNS data, from long-term historical records to real-time resolution activity, to detect and mitigate potential threats, such as new and existing malware variants and evolving attack patterns.

Monitor threat actors’ DNS footprints

Don’t lose sight of threat actors and their tactics, techniques, and procedures (TTPs) on the Internet. Intensify threat actor monitoring by tracking their historical and active DNS footprints and exposing malicious connections and infrastructures.

Provide security solutions with a complete view of the DNS

Reduce cyber blind spots by feeding security applications with the most extensive DNS intelligence, combining long-term depth, verified accuracy, and live visibility, allowing users to leverage otherwise hidden and untapped insights.

Bring attack surfaces and hidden connections to light

Widen asset discovery and vulnerability management—find suspicious and malicious DNS patterns and connections by combining scale, accuracy, and timeliness, helping ensure you or your clients are not vulnerable.

“WhoisXML was the game changer for us. It has revolutionized our ability to disrupt cybercrime in process and at scale by quickly identifying all of the vendors providing material support for scammers using sophisticated website templates that look legitimate. By quickly identifying the vendors unknowingly supporting the criminals, we can provide them with public interest justification to burn down the criminal infrastructure.”
