How to Secure Your Neon App
Last updated: January 12, 2026
Neon provides serverless PostgreSQL with security handled at the infrastructure level, but application security is your responsibility.
Step-by-Step Security Guide
1. Protect Connection Strings
Store Neon connection strings in environment variables, never in code or repositories.
2. Enable Row Level Security
Neon supports full PostgreSQL RLS. Enable it for multi-tenant data protection.
ALTER TABLE user_data ENABLE ROW LEVEL SECURITY;
CREATE POLICY user_isolation ON user_data
USING (user_id = current_user_id());3. Use Separate Branches
Neon branching creates isolated database copies. Use separate branches for dev, staging, and production.
4. Use Connection Pooling Securely
Neon's connection pooler handles connections. Ensure your client is configured for pooled connections.
5. Use Parameterized Queries
Prevent SQL injection by using parameterized queries, never string concatenation.
6. Scan Your Application
Run VAS to verify RLS and other security configurations are working correctly.

Ready to Secure Your App?
Security is an ongoing process, not a one-time checklist. After implementing these steps, use VAS to verify your Neon app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
Is Neon's managed security enough?
Neon handles infrastructure security (encryption, network isolation). You're responsible for application-level security: connection string protection, RLS policies, and query security.
How do I use Neon branching securely?
Each branch has its own connection string. Use separate branches for each environment and don't share production credentials with development branches.
