Technical Deep Dive

Zero Trust is often discussed at the network layer, but your database is where the 'crown jewels' live. DBX enables a Zero Trust posture by assuming that every connection—even from internal services—is potentially compromised. We audit your table-level grants, execution rights on functions, and Row Level Security to ensure that the principle of least privilege is technically enforced, not just documented.

Least-privilege enforcement

Lateral movement prevention

Identity-aware security

Formal grant verification

Primary Vulnerability Vectors

01
Over-privileged service accounts
02
Internal data exfiltration
03
Credential compromise blast radius

Audit Checklist

Audit 'PUBLIC' role for excessive table grants

Verify that application roles cannot drop or truncate tables

Check for cross-database schema access via postgres_fdw

Validate that only necessary roles have 'LOGIN' attributes

Audit effectively inherited permissions via nested roles

How it works

High-integrity schema introspection

Introspect

Run a read-only script to extract your database catalog. No data ever leaves your machine.

Simulate

Our engine executes billion-path simulations to find logical RLS bypasses.

Remediate

Receive copy-paste SQL fixes for every high-risk vulnerability discovered.
