CISA Automated Indicator Sharing (AIS) TAXII Server

CISA's Automated Indicator Sharing (AIS) program uses a TAXII 2.1 server to deliver STIX-formatted cyber threat indicators (CTI) and defensive measures (DM) to vetted partners. AIS includes AIS PUBLIC, FEDGOV, and CISCP feed communities. Connection requires a static IP, a Terms of Use, and an Interconnection Agreement; commercial data aggregators also redistribute AIS content to subscribers.
