“ We’ve used WhoisXML API’s data in our own investigations, and it is one of the most popular integrations among Malfors users. It is the best source we’ve found for WHOIS data, including WHOIS history and Reverse WHOIS. Analysts can pivot on DNS records or WHOIS text to uncover more infrastructure and support threat actor attribution. Our users, from SOC teams to incident responders, can access that data in just a few clicks. ”
