Step-by-Step Security Guide
1. Use Railway Variables for Secrets
Never commit secrets to your repository. Add them in Railway Dashboard → Project → Variables.
2. Use Private Networking
Connect to Railway databases via private networking, not public endpoints.
# Use private URL for internal connections
DATABASE_URL=$DATABASE_PRIVATE_URL3. Separate Environments
Use Railway environments to isolate production from staging. Each gets its own variables and databases.
4. Secure API Routes
Validate authentication in every API endpoint. Railway doesn't add auth for you.
5. Enable Deploy Protection
Require approvals for production deployments in Project Settings.
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 Railway app is secure before launch, and consider regular scans as you add new features.
Frequently Asked Questions
What's the difference between DATABASE_URL and DATABASE_PRIVATE_URL?
DATABASE_URL is accessible from the public internet. DATABASE_PRIVATE_URL uses Railway's private network, keeping database traffic internal. Always use private URLs for services within Railway.
Should I use Railway's managed databases?
Railway's managed PostgreSQL and Redis handle security configuration automatically. They're often more secure than self-managed for small teams.
