Free DNS Firewall Threat Feeds

These DNS Firewall Threat Feeds can be used by organizations running their own DNS infrastructure.  Included feeds are:

– Drop
– Coin-blocker*

*N.B. Only “Drop” is curated by Spamhaus.  The other zones are service feeds curated by third parties.  These service zones may contain false positives, that cannot be remediated.

Please be aware that these free feeds only provide protection from the worst of the worst. They do not give users the breadth of protection that our paid subscription provides. A complete list of feeds can be found on our DNS Firewall Threat Feeds page.
