TAXII 2.1 is the OASIS protocol for exchanging STIX over HTTPS. Clients discover API roots, list collections, and poll objects — the same workflow CERTs and MSSPs already use for commercial TI.

Why TAXII matters for National CERTs

TAXII is the interoperability layer between vendors. Reyhford’s ICS honeypot feed plugs into the same automation that already ingests commercial and ISAO feeds — no custom agent required.

Personal sensor collections

Customer-enrolled sensors can expose a sensor-scoped TAXII collection (org-owned) so operators see attacks hitting their own sensor without receiving only the pooled feed. See authentication and portal sensor setup. Next: Indicators of Compromise, Confidence scoring.
