Organized cybercrime has become the norm. As threat groups’ Internet infrastructure are increasingly volatile and difficult to track, WhoisXML API launched the Security Intel Exchange Program.
The program facilitates the exchange of critical domain, IP, and DNS intelligence between leading security companies and threat researchers worldwide to achieve greater scale, scope, and precision to ultimately monitor and respond to every meaningful Internet security event.
Application to the Security Intel Exchange Program is open. Contact us for more information about eligibility criteria.

Members of the Security Intel Exchange Program includes top security companies, OSINT investigators, threat researchers, and some of the largest ISPs and Internet registries.
The program enables members to collate threat data in real-time to help tackle some of the most pressing security issues and ongoing cyber attacks.
Our combined domain, DNS, and IP footprints cover billions of historical WHOIS records and DNS lookup events across most TLDs and virtually every IP address in use.
We are actively looking to provide data from our DNS, subdomains, WHOIS, and geolocation databases in exchange for data contributions from our partners’ DNS, subdomains, WHOIS databases and other potential sources.
Key criteria include the volume, freshness, and uniqueness of the partner data as well as relevance for cybersecurity, especially to monitor and investigate today’s most prominent attacks and threat groups.
Among other events, we keep a close eye on:
Some of our key coverage statistics include:
Yes, new partners and WhoisXML API typically enter into an initial evaluation period of up to several weeks during which both sides can assess the benefits derived from the data exchange.
