NestJS Guards are classes with a single goal to determine whether the route handler should handle a request. They can be used to prevent unauthorized access to endpoints in your application by checking if a user has the necessary permissions to access a specific resource. The Guards we write can protect either individual route handlers or a group of route handlers.
