Law enforcement agencies always need to stay ahead of the technology curve and how bad actors are able to take advantage of innovative developments, privacy regulations, and bulletproof hosting and other services that make it easy to set up and maintain criminal infrastructure online. But the challenge is not just adapting to the ever-changing technological landscape or digital abuse techniques but also obtaining as much connected data as possible, leading to clues for deeper and more intensified crime investigations.
Technological capabilities that aid thorough crime investigations and case resolutions can strongly benefit from a complete view of the Internet—the network that often provides law offenders an avenue, anonymity, and the audacity to commit cybecrimes. Access to real-time and historical domain, WHOIS, IP, DNS, and other Internet-related intelligence can lead to additional clues about cybercrime and perpetrators that would otherwise remain unnoticed.

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 support multiple processes that enable intelligence-led cybercrime investigations, such as:
Trace the digital footprints of law offenders, including their domains and subdomains, along with their connected IP addresses, geolocation, nameservers, and other Internet records. Broaden investigations by obtaining more clues from other properties sharing the same DNS infrastructure and characteristics.
Thoroughly examine pieces of cybercrime evidence in light of historical and real-time Internet intelligence. Provide more context to security incidents and malicious properties, such as registration, geolocation, categorization, and DNS resolution details.
Continue protecting economies, communities, entities, and individuals through real-time and early threat detection. Feed advanced law enforcement repositories and systems with real-time DNS events to detect suspicious domains, subdomains, IP addresses, and other Internet properties.
Gather the information needed to take down the bad guys and their infrastructure by looking into the registration, administration, and assignment details of confirmed malicious domains and IP addresses. Support the necessary legal documents and processes for the takedown with essential DNS intelligence.
Obtain real-time access to domain registration data to enable the timely detection of domain drop-catching and cybersquatting domains that could be vehicles for counterfeiting. Hasten the identification process by uncovering other domains registered by the offending party.

Download“WhoisXML API’s passive DNS database, even the lite version for academic purposes, has much better subdomain data coverage compared with other commercial and free databases.”
“WhoisXML API’s rich repository of domain records will be invaluable for Cyware and joint customers, as it enables automated enrichment of domain and IP content via Cyware Orchestrate.”
“We did trials with WhoisXML API to make sure the data was truly resulting in successful takedowns. We were able to consistently discover and mitigate real threats as a result of using the products.”
“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.”
