Render + PostgreSQL Security
Render's managed PostgreSQL simplifies database operations. Ensure your configuration is secure with these practices.
Why Render + PostgreSQL?
Render's managed PostgreSQL with automatic backups and SSL is popular for production applications. Configuration still requires security attention.
Common Vulnerabilities
These are the security issues we find most often in Render apps using PostgreSQL.
External Connections Enabled
Database may allow connections from any IP when it should be internal only.
Connection String in Code
Database credentials may be hardcoded instead of using environment variables.
Missing Application-Level Authorization
Application may not verify user authorization before database queries.
Shared Environment Variables
Production credentials may be copied to preview environments.
What We Check for Render + PostgreSQL
Network Access
Verify database access is restricted to internal services.
Credential Management
Check credentials are in Render environment variables, not code.
Query Authorization
Review application code for proper authorization checks.
Environment Isolation
Verify different databases for production and other environments.
Quick Security Wins
Apply these fixes right now to improve your security.
Use internal database URL for Render servicesMove all credentials to Render Environment VariablesCreate separate databases for each environmentEnable RLS for multi-user applicationsAdd authorization checks before all database operationsThe Bottom Line
Render + PostgreSQL is secure when using internal networking and environment-based configuration. Keep production data isolated from other environments.

How do I restrict access to my Render PostgreSQL database?
Use Render's internal database connection for services running on Render - this keeps traffic off the public internet. For the managed database, access is already restricted by credentials; you can't add IP allowlists, so strong credentials and SSL are essential.
Can I have different databases for production and staging on Render?
Yes, create separate PostgreSQL instances for each environment. Use different environment variables in each Render service configuration. This isolates your production data from development and staging access.
Does Render PostgreSQL support Row Level Security?
Yes, Render uses standard PostgreSQL with full RLS support. Enable RLS on your tables and create policies to restrict data access. This is especially important for multi-tenant SaaS applications sharing a database.
Is SSL automatically enabled for Render PostgreSQL?
Yes, Render's managed PostgreSQL requires SSL for all connections. You don't need to configure it - all connections are encrypted. This protects your data in transit from your application to the database.
