Shadow API Discovery You can't protect what you can't see.
Shadow APIs — undocumented, forgotten, or zombie endpoints — are the soft underbelly of modern apps. Karbon's API security platform watches live traffic, builds an inventory of every endpoint, and flags the ones nobody told security about.
Traffic-derived inventory
Karbon learns your real API surface from live traffic — not a stale OpenAPI spec — so shadow and zombie endpoints can't hide.
Drift detection
When a new endpoint appears or an old one changes shape, you're alerted. No more surprise routes shipped on Friday.
Sensitive-data flags
Endpoints returning PII, tokens, or secrets are highlighted so you can lock down the riskiest paths first.
Schema-aware
REST, GraphQL, and gRPC are parsed and understood, not just logged as opaque URLs.
Frequently asked questions
- What is a shadow API?
- A shadow API is an endpoint that exists in production but isn't in your documentation, gateway, or security review — often a leftover from an old feature or a route shipped without sign-off. Because nobody's watching it, it's a prime target. Karbon finds these from live traffic.
- How does discovery work without a spec?
- Karbon observes real requests and responses passing through the proxy and reconstructs the API surface from them. It doesn't depend on an OpenAPI file that may be outdated or missing.
- Is this part of a broader API security platform?
- Yes. Discovery feeds the same platform that handles API rate limiting, bot mitigation, and abuse detection, so inventory and enforcement stay in sync.
