Comparisons anchored on MISP, the AGPL-3.0 threat intelligence sharing platform from the CIRCL community: against OpenCTI and Yeti.
MISP's indicator sharing and correlation against OpenCTI's STIX knowledge graph: AGPL against Apache-2.0 with an Enterprise Edition, sharing communities against analysis and reporting, infrastructure needs and which SSO features each gates.
MISP for sharing indicators between organizations against Yeti for DFIR teams that keep forensic artifacts, Sigma and YARA rules with their intelligence: data models, integrations and who runs each.
The three open source threat intelligence platforms side by side: sharing (MISP), knowledge management (OpenCTI) and forensic intelligence (Yeti), with licenses, paid editions, stacks and typical team fit.
Whether to choose one or run both: how the OpenCTI MISP connector imports events, which system stays the sharing hub, what duplicating data costs in operations, and when one platform is enough.
Whether to install MISP 2.5 natively with the project's Ubuntu 24.04 installer script or run the misp-docker images. Covers what the MISP project recommends, how each is upgraded, the containers misp-docker splits MISP into, high availability options and what happens to legacy 2.4 installs.
A threat intelligence sharing platform against an incident case management tool: how TheHive's documented MISP integration turns MISP events into alerts, why they are usually paired, and the license gap (MISP AGPL-3.0, TheHive 5 commercial with a 2-user free tier).
Data model only: MISP events, attributes, objects, taxonomies and galaxies with MISP JSON and STIX exports against OpenCTI's STIX 2.1 entities and relationships fed by connectors. What each model means for analysts, sharing and moving data between them.
