Vulners
Overview
Enriches OpenCTI Vulnerability entities with Vulners intelligence: CVSS, EPSS, CISA KEV status, known exploits and related software, delivered as a ready-made STIX bundle.
Vulners is a vulnerability intelligence platform that aggregates data from a wide range of public and proprietary sources. This connector enriches OpenCTI Vulnerability entities with Vulners intelligence, including CVSS scoring, EPSS exploitation-probability, CISA KEV (Known Exploited Vulnerabilities) status, links to public exploits and proof-of-concept code, and references to affected software and products.
The enrichment follows a thin-client design: the complete STIX 2.1 bundle is built server-side by the Vulners backend, and the connector simply relays it to OpenCTI. This keeps enrichment results consistent with the Vulners platform and minimizes client-side processing. Security teams can use the enriched data to prioritize remediation based on real-world exploitation signals rather than severity alone.
