+### New TAXII 2 Threat Intelligence Sources

+* CISA TAXII Client
+* Dragos TAXII Client
+* Nozomi TAXII Client
+* Recorded Future TAXII Client
+* Unit42 TAXII Client

+Sumo Logic provides the following sources based on the underlying code of our STIX/TAXII 2 Client Source, but tailored for each of the vendors to facilitate setup:
+* CISA TAXII Client
+* Dragos TAXII Client
+* Nozomi TAXII Client

+Although we recommend these sources to get feeds from these vendors, you can instead set up JSON configurations. See [Recommended configurations](#recommended-configurations) below.

 ## JSON Configuration
 
 Sources can be configured using UTF-8 encoded JSON files with the Collector Management API. See [Use JSON to Configure Sources](/docs/send-data/use-json-configure-sources) for details.
