How Do You Collect Enough Relevant Data to Unify Fragmented Digital Identities?


Every day, you connect with suppliers, vendors, resellers, distributors, customers, users, and countless other parties to cultivate relationships with multiple entities 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. That’s why you have to unmask the digital identities of everyone you’re talking to and tackle the challenge of fragmented and widely spread-out data sources.


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.

Know Your Customer (KYC)

Determine, validate, and monitor customer identities by scrutinizing their WHOIS, IP, and DNS footprints. Deepen due diligence by exposing suspicious and malicious connections.

Cybercrime Protection and Prevention

Strengthen cybersecurity measures by determining the trustworthiness of domains, IP addresses, and email addresses through WHOIS, DNS and IP intelligence enrichment.

Third-Party Risk Management

Create and enrich the digital risk profiles of suppliers, resellers, distributors, and other third parties. Monitor their DNS activities, including domain registrations and IP connections, and assess DNS and domain infrastructure configurations.

Brand Protection

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.

Online Fraud Prevention

Intensify financial transaction verification and monitoring by examining IP addresses and uncovering all relevant details, such as geolocation, connection type, ISP, and netblock.

What Our Clients Say

"Companies can’t afford to break the speed at which they enlist new business partners. But it’d be foolish to blindly trust every unknown party on the Web. WhoisXML API brought in new perspectives on overlooked Internet properties and DNS configurations to add value to our third-party verification criteria and mechanisms."

Director of Product
Identify Verification Platform Provider

"We’re excited to get the data, as it’s above our expectations in terms of accuracy. We haven’t used data feeds from providers like WhoisXML API before. They were among the main components that we used to spin up our business."
