OpenCTI is a cyber threat intelligence platform that helps organizations structure, store, and visualize technical and non-technical information about cyber threats using open standards.
The platform addresses the challenge of managing scattered threat intelligence by providing a centralized system built on STIX2 standards for data structuration. It captures both technical details like tactics, techniques, and procedures alongside non-technical information such as attribution and victimology, linking each piece to its source with metadata including confidence levels and temporal data. The tool infers new relationships from existing data to help analysts extract meaningful knowledge from raw intelligence.
Organizations managing threat intelligence at scale should consider OpenCTI if they need a modern web-based system with GraphQL API capabilities and want to avoid vendor lock-in through open standards compliance. The platform suits teams already working with frameworks like MITRE ATT&CK or those integrating with existing security tools. It supports bidirectional data flow through imports and exports in multiple formats including CSV and STIX2 bundles, with connectors available to integrate with platforms like MISP, TheHive, and MITRE ATT&CK.
The project maintains active development with continuous integration pipelines and automated dependency updates. Code quality is monitored through coverage tracking and static analysis. The platform has established community engagement with a substantial user base participating in collaborative channels.
