API Gateway Software FAQs
Here are some answers to common questions about API gateway software:
How does API gateway software differ from an API management platform?
API gateway software focuses on technical essentials like routing, securing, and monitoring traffic. In contrast, API management platforms offer broader capabilities like developer portals, monetization, and full lifecycle management. Many organizations—from a high-growth startup to enterprise giants—use both together for complete control.
Can API gateway software handle both internal and external APIs?
Yes, most API gateway software can manage both internal and external APIs. For internal traffic, a service mesh is often used alongside the gateway to handle service-to-service communication, while the gateway manages the ingress controller for external requests entering the cluster.
What are the main security risks if I don’t use an API gateway?
Without a gateway, APIs are exposed directly, increasing the risk of unauthorized access and DDoS attacks. Gateway software centralizes auth (authentication and authorization) by enforcing protocols like JWT (JSON Web Tokens) and rate limiting, ensuring that only verified users or AI agents can access your data.
How do I know if my team needs API gateway software?
If your team manages multiple APIs, needs to enforce consistent security policies, or wants to simplify integration between services, API gateway software can help. It provides deep observability into your traffic patterns and improves performance through caching, which reduces the load on your backend services.
Is it difficult to migrate existing APIs to an API gateway?
No, most API gateway software provides migration tools, documentation, and support to help teams onboard existing APIs. Planning and testing are important to ensure smooth transitions, especially for high-traffic or mission-critical services.
