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 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.

Online Fraud Detection and Prevention

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

Regulatory Compliance

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.

Identity Access Management

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.

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."
