# Implementing Security Information Sharing with STIX 2.1

Build and share structured threat intelligence using STIX 2.1 objects
with the stix2 Python library and TAXII 2.1 transport protocol.

## When to Use

- Building a threat intelligence platform that exchanges IOCs with partner organizations
- Automating ingestion and export of indicators from MISP, OpenCTI, or other TIP platforms
- Creating machine-readable intelligence reports for ISAC/ISAO sharing communities
- Publishing threat data to a TAXII 2.1 server for downstream consumption by SIEMs and SOARs
- Converting unstructured threat reports into standardized STIX 2.1 bundles
- Enriching detection rules with context by linking indicators to malware, campaigns, and threat actors
