Frameworks help, but they do not replace threat modeling. List your assets: customer data, API keys, admin actions, and export capabilities.
Security is defaults plus discipline: reviews, dependency updates, and least privilege.
Enforce CSRF on session-backed forms, validate all inputs, and cast arrays to DTOs or validated structures before they touch models.
Lock down mass assignment with explicit `$fillable` or guarded models, and gate sensitive fields behind policies.
Rotate secrets, use environment-specific keys, and run `composer audit` in CI. Automate what repeats; review what does not.
