Governance
Governance that's on by default.
Sema enforces who can see what before any SQL runs, masks restricted columns by role, and records every question, plan and answer — so AI on sensitive data is safe to share and easy to audit.
Role-based access
Permissions enforced at plan time, per workspace and per role — before a query executes.
Column masking
PII and restricted fields are refused or masked automatically based on the asker's role.
Append-only audit
Every query, plan and config change is logged immutably and exportable to CSV.
