## What it is
OpenCTI is an open-source platform for managing cyber threat intelligence knowledge, including observables, TTPs, and threat actor information. It structures data using a STIX2-based knowledge schema and provides a GraphQL API with a modern web frontend, integrating with tools like MISP, TheHive, and MITRE ATT&CK.

## Use cases
- manage cyber threat intelligence knowledge in one place
- structure threat data using STIX2 standards
- visualize relationships between threat actors, malware, and indicators
- integrate threat feeds from MISP and MITRE ATT&CK
- share threat intelligence across a SOC team
- track IOCs and observables with confidence levels and first/last seen dates
- infer new relations from existing threat intelligence data

## When to choose
- you need a self-hosted threat intelligence platform with a STIX2 data model
- you want to aggregate and correlate CTI from multiple sources like MISP and ATT&CK
- your SOC needs to visualize and disseminate threat knowledge to analysts
- you want an open-source alternative to commercial TIPs

## When to avoid
- you only need simple IOC list storage without knowledge graph relationships
- you need a lightweight SIEM or log analysis tool rather than a CTI platform
- you cannot operate a multi-service Docker deployment with Elasticsearch and Redis dependencies
