Our verdict on DomainTools Reverse WHOIS
DomainTools Reverse WHOIS helps investigators find domains connected by shared registration information. Searches can use an email address, company or organization name, or registrant or contact name. It supports current and historical WHOIS records, making it suited to threat investigation, fraud analysis, brand protection and infrastructure research. Multi-term queries separated by a pipe character add flexibility when a search needs to cover several identifiers.
The Individual Membership is available at $99 USD per month or $995 USD per year. Both billing options include web-based research access, Reverse WHOIS searches, WHOIS history and domain reports. Individual memberships provide limited monthly Reverse WHOIS searches. Enterprise access is sold separately through DomainTools, giving larger teams a different purchasing path from the individual plans. There is no free plan for Reverse WHOIS searches.
Platform fit is a notable strength. The service is available through web-based research tools and an API, which can return matching domain lists and generate current or historical result counts and report pricing. Integrations include Anomali, Cortex XSOAR, Cortex XSIAM, CrowdStrike, Elastic, IBM QRadar, Maltego, Microsoft Sentinel, ServiceNow, Splunk, ThreatQ and Tines. Choose it when shared-registrant investigation, historical records and security-workflow connectivity matter. Teams needing unrestricted individual usage or a free starting point should consider an alternative.
