OpenCTI is an open source platform allowing organizations to manage their cyber threat intelligence knowledge and observables. It has been created in order to structure, store, organize and visualize technical and non-technical information about cyber threats.

The goal is to create a comprehensive tool allowing users to capitalize technical (such as TTPs and observables) and non-technical information (such as suggested attribution, victimlogy etc.) while linking each piece of information to its primary source (a report, a MISP event, etc.), 

With multiple tools and viewing capabilities, analysts are able to explore the whole dataset by pivoting on the platform between entities and relations. Relations having the possibility to own multiple context attributes, it is easy to have several levels of context for a given entity.
