The industry standards for Cyber Threat Intelligence

Stix taxii


TAXII (Trusted Automated eXchange of Indicator Information) is a collection of services and message exchanges to enable the sharing of information about cyber threats across product, service and organizational boundaries. It is a transport vehicle for STIX structured threat information and key enabler to widespread exchange.


STIX (Structured Threat Information eXpression) is a standardized language which has been developed by MITRE in a collaborative way in order to represent structured information about cyber threats. It has been developed so it can be shared, stored, and otherwise used in a consistent manner that facilitates automation and human assisted analysis.

Why is it important?

STIX and TAXII allow transportation of threat information among IT security and intelligence technologies. Re-aligning IT security efforts based on real-time information exchanges between government, commercial suppliers, non-profit efforts and industry partners. One organization’s reactive, is the other’s proactive.

STIX and TAXII are open community efforts sponsored by the U.S. Department of Homeland Security are heavily supported by MITRE corporation. Enjoying global adoption, the industry will need to continue to work together and build upon this platform to make STIX and TAXII standards we continue to rely on.

The ecosystem

STIX and TAXII make it easier to share and collaborate within your sector, community or with partners, which in turn creates true Cyber Intelligence communities.
