WSO2 API Manager provides strong internal API security, including token-based authentication and HTTPS support for various formats like REST. However, the newer API security features that are emerging are not available yet. They might be in development, but for now, internal API security is well-covered.

WSO2 API Manager could improve by adding external API security features, which is one area where there is room for enhancement. Internally, API security is strong, and all other necessary features are already available. It has a solid marketplace, supports both Docker and standalone setups, and offers great enterprise integration. The developer portal has greatly improved the user experience, making it simple and user-friendly wherever we’ve implemented it. Overall, it’s not as complicated as other API gateways.
