NGINX API Gateway vs OPNsense comparison

The NGINX Plus API gateway authenticates API calls, routes requests to appropriate backends, applies rate limits to prevent overloading services and to mitigate volumetric attacks, offloads SSL/TLS traffic, and handles errors and exceptions. NGINX's API gateway takes all API requests from a client, determines which services are needed, and delivers the result in a high‑performance manner.

NGINX Plus API gateway is used to protect APIs with rate‑limiting policies, enforce specific request methods, and provide fine‑grained access control:

• Ensures application backends are not overwhelmed by a problematic or malicious API clients through rate limits based on attribute of the request.
• NGINX Plus allows only specific request methods for app services. For example, you can accept only the GET method to ensure that access to your inventory service is read‑only (just returns the inventory).
• Controls access to specific resources using JSON Web Tokens (JWTs). For example, you can allow write access to a service for API clients with admin credentials, but only read access for clients with standard user credentials.
