How to Secure a Laravel App
Protect your Laravel application with these essential configurations.
Laravel is a secure framework with many built‑in protections, but misconfigurations are common. This guide covers the most important Laravel security settings: CSRF, XSS protection, SQL injection prevention, and deployment‑specific recommendations.

APP_DEBUG=True in Production critical
Missing Security Headers high
Insecure Cookie Settings medium
1. Production Configuration
Set `APP_DEBUG=false` in production. Set `APP_ENV=production`. Use environment variables for secrets (`APP_KEY`, `DB_PASSWORD`, `API_KEYS`). Set `ALLOWED_HOSTS` in `config/app.php`. Always generate a new `APP_KEY` for production (`php artisan key:generate`).
2. CSRF Protection
Laravel includes CSRF protection via `CSRF Token` middleware. Use `@csrf` in all forms. For AJAX, include the token in the `X-CSRF-TOKEN` header. Exclude routes from CSRF protection only when necessary (e.g., webhooks).
3. XSS Prevention
Laravel automatically escapes HTML in Blade templates using `{{ }}`. Use `{!! !!}` only with trusted content. Use `htmlspecialchars` for manual escaping. Always validate and sanitize user input using Laravel's validation rules.
4. Security Headers
Use middleware like `laravel-csp` or `spatie/laravel-csp` for CSP headers. Set `SESSION_SECURE_COOKIE = true` in `.env`. Set `SESSION_HTTPONLY = true`. Use `SECURE_SSL_REDIRECT = true`.
The Problem
Laravel apps often have misconfigurations
- APP_DEBUG=true exposing secrets
- CSRF protection not enforced
- Missing security headers
- Insecure cookie settings
- No CSP header
