How to Secure Your Retool App
Last updated: April 20, 2026
Retool builds internal tools that often access sensitive data. This guide covers securing your Retool applications.
Why Security Matters for Retool
Key Security Concerns
- Resource credentials stored in Retool - potential blast radius if compromised
- SQL injection possible if using raw string interpolation in queries
- Apps default to accessible by all org members - explicit restriction needed
- API endpoints created by Retool are publicly addressable (auth required)
- Staging/dev apps may accidentally connect to production databases
Security Strengths
- SOC 2 Type II certified - enterprise-grade compliance
- Self-hosted option (Retool On-Premise) for air-gapped deployments
- Comprehensive audit logging with user action tracking
- Granular RBAC - control access per app, resource, and query
- Query approval workflows for sensitive operations
- SSO integration (SAML, OIDC) for enterprise identity management
Step-by-Step Security Guide
1. Configure Resource Permissions
Use minimum required permissions for database connections. Don't connect with admin credentials.
2. Implement Row-Level Filtering
Use Retool's query parameters to filter data based on logged-in user. Don't expose all data to all users.
-- Filter by current user
SELECT * FROM orders WHERE user_id = {{ current_user.id }}3. Enable Audit Logging
Turn on audit logging to track who accesses what data and when.
4. Use SSO for Authentication
Configure SSO instead of Retool passwords for enterprise security and centralized access control.
5. Review Query Templates
Ensure queries use parameterized inputs to prevent SQL injection.
6. Set Up Access Controls
Use Retool's permission groups to restrict app and resource access by role.
Common Security Mistakes
Avoid these common Retool security pitfalls:
- Admin database credentials in resources
- No row-level filtering on queries
- Audit logging disabled
- Broad access to sensitive apps
- Unparameterized query inputs
Recommended Security Tools
Use these tools to maintain security throughout development:
Ready to Secure Your App?
Security is an ongoing process, not a one-time checklist. After implementing these steps, use vas to verify your Retool app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
Is it safe to connect Retool to production databases?
Yes, with precautions: use read-only credentials where possible, implement row-level filtering, enable audit logging, and restrict access to authorized users only.
How do I prevent SQL injection in Retool?
Use {{ }} template syntax for user inputs - Retool automatically parameterizes these. Never use string concatenation for query building.
