OpenCTI

The Sublime OpenCTI connector delivers email threat intelligence directly into your centralized threat intelligence platform, where it can be correlated with existing security telemetry, including network logs, endpoint data, SIEM alerts, and external threat feeds. This provides a comprehensive, contextualized view of the threats targeting your organization—without requiring manual enrichment or analysis.

You can access the connector here.
