Farsight Passive DNS sensors collect DNS response data received by caching, recursive DNS servers distributed around the Internet. This data, which does not contain personally identifiable information, is aggregated and made available via the Farsight Security Information Exchange (SIE) platform where it is imported into Farsight DNSDB, the world's largest passive DNS historical database. Operating a Farsight Passive DNS sensor supports anti-abuse research and enables the creation of better, more robust anti-abuse tools.
The passive DNS sensor only collects the DNS data received by a caching server as the result of recursion, so no Personal Identifiable Information (PII) is included. In fact, the Farsight platform was designed from the very beginning with privacy in mind. Our privacy-by-design approach means end-user queries cannot be seen by our sensors.
Farsight Security passionately believes that everyone should have a reasonable expectation for safety while using the Internet. Sharing passive DNS data provides the community with greater insight into how cybercriminals are using DNS to exploit the Internet.
Farsight continues to grow our Passive DNS community, and invites vetted organizations to join the Passive DNS network by configuring their DNS infrastructure to be a Passive DNS sensor.
Once you join the community, the data your hosted sensor contributes becomes a part of the global Passive DNS network, helping to fight cybercrime.
Gain free access to global passive DNS data. Those organizations that contribute their own passive DNS data are granted free access to global DNSDB data to protect their own networks and systems, or for conducting research (“give a little, get a lot”).
Data contributors become eligible for discounts on Farsight commercial services.
