CST VerdictShort answer
Mid-market and enterprise teams drowning in shadow data across hybrid infrastructure need DataGuard specifically for its AI-powered discovery that actually finds what you've missed, not just what you already know about. The platform maps data flows into AI training pipelines and RAG systems, then enforces controls through automated remediation, which means you're covering the ID.AM and PR.DS gaps that most DSPM tools skip. Fair warning: this is an on-premises deployment that requires container orchestration overhead, and it leans hard into detection and response while leaving incident recovery largely to you and your SOAR integrations. Mid-market and enterprise security teams drowning in data access sprawl across cloud and on-premises environments need Theom for its real-time identity and data flow mapping, which actually catches what's moving where instead of relying on static catalogs. The agentless architecture and Databricks Unity Catalog integration mean you get observable data lineage without the deployment overhead that kills most DSPM pilots. Skip this if you need a generalist data governance tool; Theom is built specifically for teams who treat data access control as a security problem, not an operational convenience.
