What is a WHOIS Database Download?

A WHOIS database download is a repository of intelligence containing current and historical domain registration and ownership data for millions of domain names. A WHOIS database can be useful to different types of users, including security operations centers (SOCs), security platforms, managed security providers, brand agents, and others.

Practical usage

Cybersecurity

Digital forensics and incident response (DFIR) consultants can rely on WHOIS Database Download 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.

WHOIS Database Download is also a great means to look for domains related to phishing and other malware-instigated attacks.

Security analysis and fraud detection

WHOIS Database Download can help enrich a complete list of indicators of compromise (IoCs) for your investigation needs or to improve your threat intelligence-gathering efforts.

Threat detection

Help managed security service providers (MSSPs) and managed detection and response (MDR) teams differentiate their threat detection and management services from the rest of the pack. WHOIS data is also helpful to assess website reputation.

WHOIS data is also helpful to correlate observed domain activity with threat intelligence sources to detect, understand, and mitigate threats as well as to assess website reputation.

Security platform data enrichment

Fuel your security information and event management (SIEM) and security orchestration, automation, and response (SOAR) systems and threat intelligence platforms (TIPs) with domain intelligence.

Other players, such as digital risk protection platforms, can also use WHOIS data to enrich hostnames, email addresses, and IPs identified on the surface and deep web.

Use WHOIS data in combination with other cyber threat sources to monitor and detect suspicious Internet assets that can be traced back to high-risk locations.

Domain analysis

WHOIS Database Download is a rich source of information on specific domains for cybersecurity specialists’ reconnaissance needs.

Marketing research

Researchers seeking answers to Internet-user-base-related questions can use WHOIS Database Download to gauge the maturity of existing markets and identify budding growth areas.

Market analysis

Reinforce your market intelligence analyses by gathering accurate data obtained from billions of WHOIS records. Understand the market with domain ownership data and boost your revenue.

Brand protection

Get insights from WHOIS data to catch potential trademark infringers before they can cause damage. Scour the Web for domain lookalikes that can harm your reputation and image.

Market forecasts

Marketing researchers and analysts and contact data warehouses use WHOIS Database Download to examine domain registration trends and create market forecasts.

Investment analysis

Investment banking institutions use domain registration data to enhance business intelligence on portfolio companies and monitor corporations’ domain assets.

Payment processing

Finance companies and departments use domain data to enhance their machine learning (ML) research and models for fraud detection. WHOIS data points such as location, domain age, and IP addresses can also help them spot domains that have ties to suspicious doings so they can take the necessary precautions.

WHOIS Database Download can be configured to match your specific requirements
