How to Deploy to Railway Securely
Railway makes deployment easy, but you need to configure security properly before going to production. This checklist covers environment variables, private networking, database security, and application hardening.
Find security issues automatically before attackers do.
Follow These Steps
Verify all secrets are in Railway Variables
Confirm no credentials are hardcoded in source files.
grep -rn "sk-\|password.*=.*[\x27\x22]\|DATABASE_URL.*=.*postgresql" src/ --include="*.ts" --include="*.js"Configure private networking
Use internal URLs for service-to-service communication.
Services without a public domain are automatically private on Railway.
Secure database connections
Use SSL and parameterized queries for all database connections.
const pool = new pg.Pool({
connectionString: process.env.DATABASE_URL,
ssl: { rejectUnauthorized: false }
})Add security headers and rate limiting
Configure your web framework with security middleware.
import helmet from 'helmet'
import rateLimit from 'express-rate-limit'
app.use(helmet())
app.use(rateLimit({ windowMs: 15 * 60 * 1000, max: 100 }))Deploy and scan
Deploy to Railway and scan the public URL with VAS.
What You'll Achieve
Your Railway deployment uses environment variables for secrets, private networking for internal communication, SSL database connections, security headers, and rate limiting.
Common Mistakes to Avoid
Mistake
Exposing internal services with public domains
Fix
Only assign public domains to services that need to be internet-accessible. Use Railway private networking for everything else.
