Cortex vs OpenCTI
GitHub Stats
About Cortex
Cortex is a powerful observable analysis and active response engine that pairs with TheHive to supercharge incident response workflows. It provides a unified API for running analyzers against observables - IP addresses, file hashes, domain names, URLs, email addresses, and more - using over 100 built-in analyzers that query services like VirusTotal, Shodan, PassiveTotal, MISP, MaxMind, AbuseIPDB, and many others. Analysts can submit observables individually or in bulk and receive structured reports with taxonomy-based classifications. Cortex also supports responders for active response actions like blocking IPs on firewalls, disabling user accounts, or quarantining endpoints. Its REST API and TheHive integration allow organizations to automate the tedious parts of IOC analysis while keeping analysts in control of decision-making.
About OpenCTI
OpenCTI is an open-source platform for managing cyber threat intelligence knowledge and observables. Built on a STIX2-native data model, it provides a unified view of threat data including threat actors, intrusion sets, campaigns, malware, vulnerabilities, and their relationships. OpenCTI uses a graph database (Neo4j or Amazon Neptune) to store and visualize complex relationships between entities, making it easy to understand how threat actors, TTPs, and infrastructure are connected. It supports connectors for automatic ingestion from MISP, AlienVault, VirusTotal, Shodan, and dozens of other sources. The platform includes role-based access control, workflow management for analyst collaboration, and export capabilities for integration with SIEMs and SOAR platforms.
