In the Abuse Manager Marketplace, each feed has its own “info card”, so you know exactly what you're getting.
So let's dig a little deeper into one of them.
As can be seen in the SURBL info card, we provide the following for each feed:
Feed name
Feed subscription type (base or premium). Base feeds are included in the standard subscription costs.
Feed description
The total number of reports in the threat feed
The total number of domains identified as a threat by the feed (note: a domain can have more than one report)
The cost to you per domain per month
The percentage of reports, out of the total reports from all feeds, that have been identified by this feed as threats
The categories of threats that this feed monitors, identifies and alerts on. Clicking on the category name will provide you with more information
