Technical Deep Dive

Google Cloud SQL integrates deeply with IAM, but the 'database-native' permission layer often gets out of sync with GCP policies. DBX audits your Cloud SQL instance to ensure that IAM-linked users don't have excessive 'postgres-native' grants. We also verify that your Cloud SQL Proxy or Auth Proxy setup isn't bypassed by weak internal network permissions.

Audit Checklist

Audit IAM-to-Postgres role mappings

Verify that Cloud SQL Auth Proxy is strictly required

Check for public 'postgres' role grants on user schemas

Validate that 'cloudsqlsuperuser' is strictly controlled

Audit cross-project database access vulnerabilities

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.
