DBX vs Microsoft Defender for Business

DBX is a web-based security analysis tool for PostgreSQL and Supabase databases. It examines how identities can reach database objects through RLS policies, grants, functions, storage, relationships, and tenant boundaries. DBX inspects live security objects and uses a deterministic rule engine and permission graph to evaluate practical access. It groups individual weaknesses into attack paths and reports severity, confidence, and evidence. Each deterministic finding includes a proposed migration linked to the relevant object, with an expected security effect and compatibility risk. The snapshot contains catalog metadata, including schemas, policies, grants, routines, and relationships, but no database rows. DBX says its snapshot workflow requires no database password, persistent connection, agent, or production write access; scanning is designed for a dedicated least-privilege role with catalog permissions. A language model explains verified findings and drafts remediation for human review. DBX does not test application code, network controls, or client authorization logic, and it makes no compliance certification claims. Free unlimited introspection is available; Full Remediation costs $195, paid once.
