Neon Security Checklist
Last updated: January 12, 2026
Use this checklist to ensure your Neon application is secure before launch. 4 critical items require immediate attention.
Why This Security Checklist Matters
Security checklists serve as systematic guides for identifying vulnerabilities that might otherwise be overlooked during rapid development cycles. For Neon applications specifically, this checklist addresses the most common security gaps that emerge when using AI-assisted development workflows.
Research from multiple security organizations indicates that approximately 80% of AI-built applications contain at least one exploitable vulnerability at launch. The vulnerabilities are often predictable—they follow patterns that this checklist is designed to catch. By systematically reviewing each item, you significantly reduce the risk of launching an insecure application.
Unlike generic security checklists, this guide focuses specifically on vulnerabilities prevalent in Neon applications. Each item has been prioritized based on real-world attack patterns and the potential impact of exploitation. Critical items should be addressed before any production deployment.
Critical Priority
Critical items can lead to complete application compromise, data breaches, or unauthorized access to all user accounts. These must be addressed before deploying to production. Attackers actively scan for these vulnerabilities.
High Priority
High priority items represent significant security risks that could allow unauthorized access to sensitive data or functionality. While not immediately catastrophic, these vulnerabilities should be fixed as soon as possible.
Medium/Low Priority
Medium and low priority items strengthen your overall security posture. While they may not be immediately exploitable, addressing them prevents attack chains and defense-in-depth gaps.
Manual vs Automated Security Checking
While manual security reviews are thorough, they're time-consuming and prone to human error. Automated scanning catches common vulnerabilities instantly, freeing you to focus on business logic and complex security decisions.
Items VAS Automates
- Exposed API keys and secrets in JavaScript bundles
- HTTP security header configuration
- Supabase RLS policy testing
- Firebase Security Rules validation
- Cookie security attributes
Manual Review Still Required
- Business logic vulnerabilities
- Custom authentication implementations
- Access control logic in API routes
- Data validation requirements
- Third-party integration security
Row Level Security
Enable RLS on all tables with user data
AutoNeon supports full PostgreSQL RLS - use it for multi-tenant security
Write RLS policies for each operation
AutoCreate SELECT, INSERT, UPDATE, DELETE policies
Pass user context for RLS
Use session variables to identify users in RLS policies
Test policies in Neon SQL Editor
Use Neon's SQL editor to verify RLS behavior
Connection Security
Use connection pooling securely
Neon's pooler handles connections - configure appropriately
Use SSL for all connections
Neon requires SSL by default - ensure your client supports it
Protect connection strings
AutoStore Neon connection strings in environment variables, not code
Use separate credentials per environment
Create different roles/databases for dev, staging, production
Branch Security
Use separate branches for environments
Neon branching creates isolated copies - use for staging
Don't share production credentials with branches
Each branch has its own connection string
Clean up unused branches
Delete old branches to reduce attack surface
Protect branch data in previews
Be aware that branch data may be from production snapshot
Access Control
Review project member access
Audit who has access to your Neon project
Use roles with minimal privileges
Create database roles with only needed permissions
Rotate credentials periodically
Regularly rotate database passwords and connection strings
Enable IP restrictions if available
Restrict database access to specific IP ranges
Don't Check Manually

Run Automated Security ScanFrequently Asked Questions
What's the difference between critical and high priority items?
Critical items represent immediate security risks that could lead to data breach if not addressed - like missing database access controls or exposed secrets. High priority items are important but typically require an additional vulnerability to exploit.
Can I skip low priority items?
Low priority items provide defense-in-depth but aren't immediate risks. Address all critical and high items before launch. Low items can be added post-launch, but shouldn't be ignored entirely - they protect against edge cases and future vulnerabilities.
How often should I re-run this checklist?
Re-run after major feature additions, authentication changes, or new database tables. Set up automated scanning with VAS to catch regressions. Many teams integrate security scans into their CI/CD pipeline for continuous verification.
What does 'Auto-Scanned' mean on checklist items?
Items marked 'Auto-Scanned' can be automatically verified by VAS. Instead of manually checking each item, run a VAS scan to instantly verify these items against your deployed application. Non-automated items require manual verification.
