Join us for a webinar where we will discuss how modern recursive name servers can keep a record of every response they see – every answer, referral and error. That passive domain name system (DNS) data can be a goldmine that helps you detect suspicious activity, trade name infringement and more.

During this webinar we will discuss how passive DNS data is collected, replicated and how it can be analyzed to find security relevant information.

You’ll also learn how you can get involved by setting up passive DNS collection on your own name servers or by subscribing to feeds of suspicious or malicious domain names and IP addresses.
