What is TAXII?
Trusted Automated Exchange of Intelligence Information: a protocol for sharing STIX threat intelligence between systems over HTTPS.
TAXII is a protocol, also maintained by OASIS, for exchanging threat intelligence over HTTPS. A TAXII server hosts collections of STIX objects, and clients poll or push to them.
It lets threat intelligence platforms, SIEMs and sharing communities subscribe to each other's feeds automatically, without custom integrations for each source.
