Cyber threat intelligence lies behind most cybersecurity strategies, platforms, or operation centers. Yet the scale and scope of today’s ever-dynamic and geographically dispersed threat landscape means organizations cannot settle for partially informed or run-of-the-mill threat intelligence. Accounting for every bit of information, including countless real-time and historical Internet events, matters to proactively notice, monitor, and protect networks from threat actors.
Cyber threat intelligence can only be as good as the raw data used in its development. Historical coverage of DNS, WHOIS, and other Internet records facilitates malicious infrastructure investigation and disruption by exposing otherwise hidden connections. These critical Internet events significantly contribute to every stage of the threat intelligence development cycle—enabling early threat detection, real-time threat analysis, broader threat expansion, and timely threat disruption.
Our enterprise packages offer scalable data access, flexible licensing models, and better coverage and higher total value delivered. Contact us for information on our packages and the contained premium, tier 1, and tier 2 products.

Contact UsThe WhoisXML API data engine is built and frequently upgraded to offer you the most complete, updated, and unique Internet intelligence footprints since 2010. Don’t get lost in all the red tape and unforeseen technical complexities of finding your own domain and DNS data. Our technology is ready to give back months or years of development cycle time to your most pressing and mission-critical projects and deployments.
Our Internet intelligence sources enriched the various processes required in the development of cyber threat intelligence, including:
Detect suspicious domains, subdomains, nameservers, IP addresses, and other Internet-related records as soon as they get added, updated, or dropped, including cyber properties that seem to imitate legitimate brands and those that currently or historically share the same infrastructure as known threats.
Gather accurate geolocation, ownership, administration, DNS infrastructure details, and other Internet intelligence raw materials needed to deepen threat contextualization and bring you one step closer to fully understanding and pinning down threat actors.
Analyze tactics, techniques, and procedures (TTPs) in real-time by observing and detecting old and new patterns in domain registration events, nameserver assignments, registrar affiliation, top-level domains (TLDs), IP geolocation, and other data that can be associated with threat actors.
Anticipate the badness of a domain, subdomain, or IP address before they are weaponized by following breadcrumbs left behind by the adversaries’ inevitable reuse of digital assets, such as nameservers, registrars, IP ranges, Secure Sockets Layer (SSL) certificates, and suspicious domain types.
Track down malicious properties to their respective owners, registrars, registries, and Internet service providers (ISPs) to intercept threat actors. Expose their domain, DNS, and IP connections to take steps toward disrupting malevolent infrastructure.
Pinpoint domains, subdomains, and IP addresses that currently share the same details or infrastructure as those used in confirmed threats or have recently or historically done so to support threat prevention efforts, from preemptive blocking to fueling security heuristics analysis and threat prevention models.
A comprehensive and unhindered view of real-time and historical Internet events can help make your cyber threat intelligence more complete and powerful. Learn how in this use case sheet.

What Our Clients Say
"Through WhoisXML API, we can access DNS, WHOIS, and IP intelligence with real-time and passive coverage. The data works seamlessly with our other intelligence sources, allowing us to derive the most complete cyber threat intelligence so we can analyze and predict threat actor behaviors and provide timely insights to our users."
CTO & Co-Founder
Threat Intelligence Feed Provider
"We found certain nameservers that were always used for a phishing campaign, having those in our rules enabled us to catch phishing sites before they affected our user base. WhoisXML API is a responsive and reliable provider of domain intelligence. Whenever there are issues, they are quick to respond and resolve them. Working with them is smooth and straightforward."
