Lucidum

Lucidum is a cyber asset and security data platform (CAASM) that ingests, correlates, and enriches data from more than 500 sources to give security and IT teams a unified inventory of assets, identities, data, and their relationships. The Security Data Fabric platform eliminates blind spots by connecting to existing SIEM, cloud, endpoint, and identity systems without extra ingestion charges, and surfaces unseen systems and accounts for exposure and attack-surface management. Lucidum was acquired by Cyderes and its capabilities are now delivered as part of the Cyderes "Meridian" platform. This profile originated as a GGV Capital portfolio lead and was enriched from Lucidum public web surface; the company publishes no public developer API.

Lucidum is profiled on the APIs.io network. Tagged areas include Company, Security, CAASM, Cyber Asset Management, and Attack Surface Management.

Lucidum’s developer surface includes documentation, support, and 6 more developer resources.
