How to Secure Your Render App
Last updated: January 12, 2026
Render handles infrastructure security, but application configuration is your responsibility. This guide covers securing Render deployments.
Step-by-Step Security Guide
1. Use Environment Variables for Secrets
Add secrets in Render Dashboard, never in code. Render encrypts environment variables.
2. Use Private Services
Internal APIs and workers should be private services, not publicly accessible.
3. Use Private Database Connections
Connect to Render databases via internal URLs, not public endpoints.
4. Configure Auto-Deploy Carefully
Consider disabling auto-deploy for production services to require manual approval.
5. Secure API Routes
Validate authentication in every API endpoint. Render doesn't add auth for you.
6. Scan Your Application
Run VAS to catch security issues in your deployed application.

Ready to Secure Your App?
Security is an ongoing process, not a one-time checklist. After implementing these steps, use VAS to verify your Render app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
What's the difference between public and private services?
Public services have external URLs accessible from the internet. Private services are only accessible within your Render network. Use private for internal APIs and workers.
Are Render environment variables secure?
Yes, Render encrypts environment variables. They're only exposed to your service runtime and not visible after creation.
