Quick Wins
Security Best Practices
#1Use Railway Variables for Secrets
criticalNever commit secrets to your repository. Use Railway's environment variable management.
Implementation
Add secrets in Railway Dashboard → Project → Variables
#2Use Private Networking for Databases
criticalConnect to Railway databases via private networking, not public endpoints.
Implementation
Use DATABASE_PRIVATE_URL instead of DATABASE_URL for internal connections
#3Enable Deploy Protection
highRequire approvals for production deployments to prevent accidental or unauthorized changes.
Implementation
Configure deploy protection in Project Settings
#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 Railway environments to isolate production from staging and development.
Implementation
Create separate environments with their own variables and databases
#6Configure Health Checks
mediumSet up health checks to ensure only healthy instances receive traffic.
Implementation
Configure health check endpoint in Service Settings
Common Mistakes to Avoid
Using public database URL
Exposes database to internet, relying only on password
Use DATABASE_PRIVATE_URL for internal services
Same secrets in all environments
Production data accessible from development
Use separate environments with different credentials
No deploy protection
Anyone with access can push to production
Enable deployment approval requirements
The Practices Railway Apps Most Often Skip
The Railway practices most often skipped in what we scan.
Storing database URLs and secrets in environment variables, not git.
Using private networking for internal service traffic.
Adding the app-level security the platform does not provide for you.
Verify Your Railway App Security
Following best practices is the first step. Verify your app is actually secure with a comprehensive security scan.
Scan your Railway app →Frequently Asked Questions
Are Railway environment variables secure?
Yes, Railway encrypts environment variables. They're only exposed to your deployments and not visible in logs.
Should I use Railway's managed databases?
Railway's managed databases handle security configuration automatically (encryption, backups, private networking). They're often more secure than self-managed for small teams.
How do I secure database connections?
Use DATABASE_PRIVATE_URL for private networking between Railway services. This keeps database traffic off the public internet.
