Launch PassiveDNS Service


Domain Name System (DNS) is used for every transaction on the Internet, good or bad. Farsight Security, Inc. provides a comprehensive set of solutions that provide real-time and historical information about the everchanging Global DNS. By enriching your existing Threat Intelligence with our data, you can more quickly detect, respond and prevent the next cyberattack and protect your business.


Farsight DNSDB is the largest, most proven real-time and historical collection of Passive DNS data available in the market today. DNSDB can provide information about threat actors and their motives by answering such questions as: What domain names map to “this” IP address, now and in the past? When was “this” name first used and by whom? What domain names share this same MX record? Learn more about our latest integration with Splunk and how DNSDB works.
