API gateways protect entry points, not everything behind them. If backend services assume all requests are trusted simply because they passed through the gateway, internal bypass paths become dangerous.
Misconfigurations, internal network access, or compromised services can allow traffic to reach backends without proper enforcement. For this reason, backend services should still validate identity and authorization independently.
Gateways are an important layer, but they can’t be the only one.
Takeaway: Gateway security doesn’t replace service-level security.
