Practical Uses: Why Buy Our Whois Database

Cybersecurity professionals use WHOIS download services for reconnaissance needs and security analysis, such as the correlation of domain activity for threat detection and mitigation, as well as for fraud prevention and the identification of Internet assets from high-risk locations.
WHOIS database download can be used to enrich security information and event management (SIEM), Security Orchestration, Automation, and Response (SOAR), Threat Intelligence Platform (TIP), Automation, and Orchestration Tools.
Registrars purchase WHOIS database downloads to keep track of domains.
Digital risk protection products can work with WHOIS intelligence to gather context on hostnames, IPs, and email addresses found on pastebins and forums as part of pivot and enrichment analyses.
Law enforcement agencies use WHOIS data downloads to identify all the connected domains, websites, and IP addresses associated with fraudulent activities and criminals.
WHOIS data downloads help managed security service providers (MSSP) and managed detection and response providers (MDR) to differentiate their threat detection and management services.
Marketing research analysts and contact data warehouses use WHOIS data to examine domain registration trends and create market forecasts.
Utilizing data from billions of WHOIS records helps you offer a greater strategic advantage over competitors. Develop accurate statistical market insights, providing an authoritative market understanding for your marketing and sales clients.
Brand protection agents can rely on WHOIS data downloads to check for registrations that strongly overlap with their brands and trademarks and take action to prevent highly-similar and copycat domain names from confusing customers and visitors.
Digital forensics and incident response (DFIR) consultants can rely on WHOIS data downloads to provide their clients with easy-to-read lists of domains that may have ties to cybercrime, allowing them to beef up their cybersecurity posture.
Fraud solution vendors, payment processing companies, and banks can integrate domain data points from our WHOIS database into their models and applications. By correlating the data with other sources, they can improve their ability to detect inconsistencies indicative of fraud or connections to domain names flagged malicious.
WHOIS database download is also an excellent means to look for domains related to phishing and other malware-instigated attacks.
Contact data warehouses can purchase WHOIS data to enrich, verify and enhance business contact data.
Researchers seeking answers to Internet-user-base-related questions can buy WHOIS database downloads to gauge the maturity of existing markets and identify budding growth areas.
Investment banking institutions use domain registration data to enhance business intelligence on portfolio companies and monitor corporation domain assets.
WHOIS data can help investigate Indicators of Compromise (IOC) and produce Threat Intelligence.
