API Security

Your APIs are your attack surface.
Map them honestly.

CYBRET discovers every endpoint you actually expose — documented, shadow, or zombie — and checks each one against the OWASP API Top 10 with proof of exploit. BOLA, BFLA, schema drift, broken auth, missing rate limits: caught at the identity and object level, not at the URL pattern level. No more passing the test suite while failing production.

Capabilities

Built for the way
APIs actually fail.

◈
Runtime endpoint discovery
Passive traffic sampling and gateway introspection find every live route, including undocumented, deprecated, and staging endpoints still answering in prod.
◎
BOLA/BFLA identity checks
For each object-returning endpoint, CYBRET rotates identities and object IDs to prove ownership enforcement exists, not just that 200 came back.
⎔
Schema-drift monitor
Live traffic is diffed against your OpenAPI, GraphQL, or gRPC contract. New fields, new methods, and quietly widened types surface in under a minute.
⌖
Auth-middleware audit
Every route gets traced to the auth code that guards it. Missing middleware, optional checks, and "if user is admin" one-liners are called out explicitly.
◐
Rate-limit / quota enforcement
Endpoints without rate-limits, with per-IP limits that do not account for auth, or with quotas bypassable by ID rotation are all tested and scored.
▤
OpenAPI compliance gates
CI gates block merges when a route drifts from spec, loses auth, or widens a response. Reviewers see exactly which schema line moved.
How it works

From spec to evidence,
endpoint by endpoint.

API security vendors tell you what an endpoint looks like. CYBRET tells you who can reach it, what they can do to it, and which line of code needs to move to stop them.

01
Ingest spec & traffic
OpenAPI, GraphQL SDL, or gRPC protobufs go in one side; live traffic from your gateway goes in the other. The diff is the starting point.
Spec + reality
02
Map identities to objects
CYBRET models which identity types can see which object types, which endpoints mutate which, and which auth middleware gates each route.
Object-level
03
Probe with proof
Safe probes rotate identities and IDs against object-returning routes, generate crafted payloads for BFLA, and test rate-limit bypasses end-to-end.
Evidence-backed
04
Gate and govern
Findings flow to developers with the exact route, middleware line, and fix diff. Merge gates and runtime guardrails keep regressions from landing.
