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.
About osquery
osquery, developed at Facebook, exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data - running processes, loaded kernel modules, open network connections, browser plugins, hardware events, file hashes, and hundreds of other system attributes are all available as SQL tables. For security teams, this means you can query your fleet in real-time: 'SELECT * FROM processes WHERE name LIKE \'%miner%\'' finds cryptominers, 'SELECT * FROM listening_ports WHERE port = 4444' finds suspicious listeners. osquery supports scheduled queries that log differential changes over time, making it powerful for continuous security monitoring and compliance verification. It runs on Linux, macOS, Windows, and FreeBSD, and integrates with fleet management tools like Fleet (formerly Kolide) for centralized querying and alerting across thousands of endpoints.
