PostgreSQL and MongoDB take different approaches to data security. PostgreSQL offers Row Level Security, while MongoDB relies on role-based access control.
Scan Your AppPostgreSQL's RLS provides more granular row-level control, making it better suited for multi-tenant applications. MongoDB's flexibility can make security harder to reason about.
For applications needing row-level security (like those built with Supabase), PostgreSQL is the better choice. Use VAS to verify your security configuration regardless of database.
When comparing PostgreSQL vs MongoDB, consider these broader security trends.

“Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.”
Regardless of which platform you choose, VAS scans for security issues specific to your stack.
