A widely deployed open-source and enterprise API gateway used for routing, authentication plugins, and rate limiting across microservices and hybrid environments.
Kong governs API traffic at the network edge: routing requests, enforcing rate limits, terminating TLS, and validating tokens through plugins before traffic reaches the services behind it. That is the right architecture for protecting the provider side of an API call. The gap appears on the caller side. Kong verifies that a request carries a valid credential. It cannot attest the identity of the workload or AI agent that obtained that credential, and it has no visibility into whether the caller’s runtime posture is healthy or whether the request is a legitimate task versus an adversarial one. Aembit operates at the caller layer. Before the request reaches Kong, Aembit attests the workload’s runtime identity, evaluates access policy, and issues a short-lived, identity-bound JWT or OAuth token. When that token arrives at Kong, it is not a static API key or a reused secret. It carries cryptographic proof of the caller’s identity. The two tools protect opposite ends of the same API call and are both present in mature microservices environments.
Aembit does not replace Kong. Kong handles network-layer traffic management that Aembit is not designed to perform.
Aembit issues short-lived, workload-bound JWTs and OAuth tokens that Kong validates through its authentication plugins (JWT plugin, OAuth 2.0 plugin, or custom plugins). When a workload or AI agent needs to call an API protected by Kong, Aembit attests the workload’s runtime identity and issues a credential bound to that identity. Kong receives the token, validates it against the configured JWKS endpoint or authorization server, and applies its routing and rate limiting policies as normal.
The result is that Kong’s authentication pipeline is no longer validating static API keys or reusable secrets. It is validating short-lived, identity-bound tokens. The workload never stores a credential, and the token cannot be reused after expiry.
Organizations already running Kong do not need to modify their gateway configuration significantly. Aembit slots in as the authorization server that issues tokens Kong already knows how to consume.
Kong and Aembit protect opposite ends of the same API call.
Kong sits inline on the data plane between the network and the APIs it protects. It handles the provider-side problems: routing requests to the right upstream service, enforcing rate limits, terminating TLS, and applying coarse-grained access policy based on token presence and claims. For AI agent workloads, Kong can enforce quotas and validate token format, but it cannot determine whether the calling agent is the one that was supposed to make the call, whether its runtime environment is healthy, or whether the request represents a legitimate task.
Aembit operates on the control plane at the caller side. Before the request is made, Aembit establishes trust: attesting the workload’s runtime identity using Kubernetes service account tokens, AWS metadata, or other platform signals; evaluating conditional access policy; and injecting a short-lived credential directly into the request. By the time the token arrives at Kong, the caller’s identity has already been cryptographically established.
Organizations with both tools get coverage at both ends: Aembit on the outbound side establishing caller identity, Kong on the inbound side enforcing network-layer policy. Neither tool does the other’s job, and neither is redundant.
