Security Best Practices
#1Use Environment Variables for Secrets
criticalNever commit secrets to your repository. Use Render's environment variable management.
Implementation
Add secrets in Render Dashboard → Service → Environment
#2Use Private Services
criticalServices that don't need public access should be private, accessible only within your Render network.
Implementation
Set service type to 'Private Service' for internal APIs and workers
#3Configure Auto-Deploy Carefully
highConsider whether automatic deploys are appropriate for production services.
Implementation
Disable auto-deploy for production, use manual or branch-protected deploys
#4Secure API Routes
highValidate authentication and authorization in every API endpoint.
Implementation
Check auth tokens and user permissions at the start of each route
#5Use Separate Environments
highUse Render environments or separate services for production and staging.
Implementation
Create separate services with different environment variables
#6Enable Health Checks
mediumConfigure health checks to ensure only healthy instances receive traffic.
Implementation
Configure health check path in Service Settings
Common Mistakes to Avoid
All services set to public
Internal services don't need public internet access
Use private services for anything that only your other services access
Auto-deploy to production
Any push deploys immediately without review
Disable auto-deploy for production, require manual deployment
Same environment for all stages
Staging can affect production data
Create separate services with isolated databases
Verify Your Render App Security
Following best practices is the first step. Verify your app is actually secure with a comprehensive security scan.

Are Render environment variables secure?
Yes, Render encrypts environment variables. They're only exposed to your service and not visible in logs or the dashboard after creation.
What is a private service?
Private services are only accessible within your Render network. They don't have public URLs and can only be reached by your other Render services.
How do I secure database connections?
Use internal database URLs when connecting from Render services. Enable SSL for all database connections.
