OpenCTI (Open Cyber Threat Intelligence) is an open‑source platform that centralizes and structures cyber‑threat intelligence—merging technical data (e.g., TTPs, observables) and contextual information (e.g., attribution, victimology)—while enforcing STIX‑2 standards, GraphQL APIs, and connectors to tools like MISP, TheHive, and MITRE ATT&CK. It is aimed at security operations teams, threat analysts, and organizations that need a free‑as‑in‑freedom knowledge‑management and sharing solution for both technical and non‑technical threat data.
