OpenCTI vs Pulse Intelligence

OpenCTI has no write-up on Specifiction yet; its figures are above.

Pulse Intelligence is an open-source, self-hosted threat intelligence workspace for analyst workflows. It organizes threat actors, aliases, campaigns, indicators, reports, sources, CVEs and ATT&CK mappings, and ingests public feeds including CISA KEV, NVD, FIRST EPSS, abuse.ch, OTX, vendor blogs and security news. Indicator enrichment uses OTX, AbuseIPDB and VirusTotal, with Redis-backed quota controls. Analysts can save hunts across indicator fields, receive alerts for new matches and export results as CSV, STIX 2.1, MISP JSON, or Snort and Suricata rules. Scheduled Markdown reports can cover new indicators, KEV additions, hunt alerts and feed health. A public read-only API with scoped keys supports integrations; its default limit is 120 requests per API key per 60-second window, and indicator pages are capped at 500. The project lists Argon2id passwords, database-backed session cookies, hashed API keys and an admin-only audit log. Deployment requires Node.js 20.9+, PostgreSQL 17 or compatible PostgreSQL, and a Redis-compatible server. Native and Docker Compose deployment paths are documented.
