OpenCTI
Open Cyber Threat Intelligence Platform
...The platform enables teams to correlate technical indicators such as observables and TTPs with higher-level context like attribution and victimology, creating a unified intelligence knowledge base. OpenCTI is built to integrate with external tools including MISP, TheHive, and MITRE ATT&CK, allowing it to function as a central intelligence hub in security operations. Its design emphasizes traceability by linking intelligence objects back to their original sources and tracking confidence levels and temporal metadata.
