Radware highlights that API gateways, while essential as a single entry point for API calls and offering basic functions like authentication, authorization, rate limiting, and traffic management, are not sufficient on their own to fully secure APIs.

They also face challenges with false positives that limit automated threat response and can be vulnerable due to misconfigurations, making dedicated API security solutions necessary to complement API gateways for comprehensive protection.
