Render Security Best Practices

Secure your Render deployments with these essential practices. From environment variables to private services.

Verify your app follows these best practices automatically.

Render handles infrastructure security, but application security is your responsibility. These practices help you deploy securely on Render.

Quick Wins

Verify no secrets in git repository
Audit which services are public vs private
Review auto-deploy settings
Test API routes without authentication
Configure separate environments

Security Best Practices

#1Use Environment Variables for Secrets

critical

Never commit secrets to your repository. Use Render's environment variable management.

Implementation

Add secrets in Render Dashboard → Service → Environment

#2Use Private Services

critical

Services 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

high

Consider whether automatic deploys are appropriate for production services.

Implementation

Disable auto-deploy for production, use manual or branch-protected deploys

#4Secure API Routes

high

Validate authentication and authorization in every API endpoint.

Implementation

Check auth tokens and user permissions at the start of each route

#5Use Separate Environments

high

Use Render environments or separate services for production and staging.

Implementation

Create separate services with different environment variables

#6Enable Health Checks

medium

Configure 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

Why it's dangerous:

Internal services don't need public internet access

How to fix:

Use private services for anything that only your other services access

Auto-deploy to production

Why it's dangerous:

Any push deploys immediately without review

How to fix:

Disable auto-deploy for production, require manual deployment

Same environment for all stages

Why it's dangerous:

Staging can affect production data

How to fix:

Create separate services with isolated databases

Frequently Asked Questions

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.
