How API Gateways Are Becoming Security Perimeters

In this episode of The API Podcast, Lucas and Luna explore how API gateways have evolved from simple reverse proxies into critical security perimeters. They break down a real-world case: how a mid-sized fintech company used gateway-level policies to block a credential-stuffing attack before it reached their application servers. Topics include gateway authentication strategies, the trade-off between centralised and distributed security, and why rate limiting alone isn't enough. They also discuss how modern gateways like Kong and Envoy support pluggable security policies, and what the rise of zero-trust architectures means for API design. If you've ever wondered whether your API needs its own security layer, this episode offers a concrete framework for thinking about gateway-level protection. #APIGateway #SecurityPerimeter #Fintech #CredentialStuffing #ZeroTrust #KongGateway #EnvoyProxy #APISecurity #RateLimiting #Authentication #Plugins #ReverseProxy #Technology #TechPodcast #APIDesign #CloudNative #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
