Laravel Security Best Practices

Comprehensive security guidance for Laravel applications to protect against common vulnerabilities.

When to Activate

• Adding authentication or authorization
• Handling user input and file uploads
• Building new API endpoints
• Managing secrets and environment settings
• Hardening production deployments

How It Works

• Middleware provides baseline protections (CSRF via VerifyCsrfToken, security headers via SecurityHeaders).
• Guards and policies enforce access control (auth:sanctum, $this->authorize, policy middleware).
• Form Requests validate and shape input before it reaches services.
• Rate limiting adds abuse protection alongside auth controls.
• Data safety comes from encrypted casts, mass-assignment guards, and signed routes.
