How Do You Collect Enough Relevant Data to Unify Fragmented Digital Identities?
Business Problem
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.
Data-Driven Solution
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.
