Every day, you connect with suppliers, vendors, resellers, distributors, customers, users, and countless other parties to cultivate relationships through different digital channels. But the inherent and emerging blind spots of the Internet, alongside persistent and resourceful threat actors, make these virtual relationships potentially risky and untrustworthy. There’s an urgent need to tackle the challenge of fragmented and widely spread-out data sources by unmasking the digital identities of everyone you’re talking to for better regulatory compliance, fraud detection, and merchant and customer identity verification.
Implementing a zero-trust security framework calls for a unified view of the DNS for continuous and accurate identification, certification, and verification of digital identities—suppliers, vendors, resellers, distributors, customers, users, employees, or anyone really. WHOIS, domain, IP, and other Internet intelligence sources can complement and enrich sophisticated security solutions and strategies, helping you tread the fine line between relationship cultivation and network protection.

Our Internet intelligence footprints have enabled a variety of use cases, among which:
Help insurers, reinsurers, and brokers assess and quantify the cyber risks of insurance buyers by identifying and attributing possible cyber attack vectors and risk exposures.
Determine, validate, and monitor customer identities by scrutinizing their WHOIS, IP, and DNS footprints. Deepen due diligence by exposing suspicious and malicious connections.
Strengthen cybersecurity measures by determining the trustworthiness of domains, IP addresses, and email addresses through WHOIS, DNS and IP intelligence enrichment.
Create and enrich the digital risk profiles of suppliers, resellers, distributors, merchants, and other third parties. Monitor their DNS activities, including domain registrations and IP connections, and assess DNS and domain infrastructure configurations.
Enable multifaceted brand protection, including assessing and monitoring distribution channels, preventing brand abuse, and supporting trademark prosecution and Uniform Domain-Name Dispute-Resolution Policy (UDRP) complaints.
Intensify financial transaction verification and monitoring by examining IP addresses and uncovering all relevant details, such as geolocation, connection type, ISP, and netblock.
Meet regulatory requirements set by various government agencies and international organizations to avoid costly penalties. Do your due diligence before conducting business with any entity.
Ensure that only authorized users can access specific resources and systems by expanding your DNS resolution scrutiny to include connections to suspicious web properties, WHOIS ownership details, and other Internet-related clues.

“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.”
