WhoisFreaks is a domain and IP intelligence platform that turns internet identifiers into structured, queryable data. Security analysts, fraud teams, brand protection specialists, and data engineers use it to answer one question reliably: who is behind this domain, and how has it changed over time. The platform delivers WHOIS, DNS, SSL certificate, IP geolocation, subdomain, and newly registered domain data through REST APIs, downloadable databases, and browser-based lookup tools. Every record is parsed and normalized into consistent JSON, XML, or CSV, so ingestion into a SIEM, SOAR, data warehouse, or internal application takes hours instead of weeks. Core capabilities: Live and historical WHOIS across 1500+ gTLDs and ccTLDs, with records dating back to 1986 Reverse WHOIS by registrant email, name, organization, or keyword to map an entire portfolio controlled by one party DNS lookups covering A, AAAA, MX, NS, TXT, SOA, and CNAME records, plus historical DNS to track infrastructure changes SSL certificate data including issuer, validity window, and chain details IP geolocation and ASN ownership enrichment Subdomain discovery for external attack surface mapping Daily feeds of newly registered, expired, and dropped domains Bulk database downloads sliced by TLD, country, registrar, or registrant Common use cases: Phishing and typosquatting detection, including lookalike domain monitoring against your brand SOC alert enrichment through bulk WHOIS and DNS pivots inside SIEM and SOAR workflows Takedown preparation using registrar and abuse contact data Vendor and counterparty due diligence based on domain age and ownership history Threat actor infrastructure mapping through shared registrants, name servers, and certificates Market and registration trend research using historical and newly registered domain datasets Coverage includes 800M+ tracked domains and 4.4B+ WHOIS records, refreshed daily. Teams choose WhoisFreaks for predictable credit-based pricing, documented endpoints with no minimum contract, and direct engineering support instead of a ticket queue.
