API authentication audit
Fixed-scope review of OAuth/OIDC configuration, API keys, and gateway policies with a written findings report.
API Haven Consulting
Production APIs fail in predictable ways when OAuth flows, token lifetimes, and gateway policies are treated as afterthoughts. We help Malaysian product teams close those gaps through scoped reviews and hands-on authentication design.
+60-7-0000-1716Where API authentication work stalls
Teams often ship REST or GraphQL endpoints with inconsistent scope checks, refresh-token handling that breaks mobile clients, or service-to-service trust that relies on long-lived shared secrets. The symptoms show up as intermittent 401 loops, audit findings on session fixation, and integration partners blocked during onboarding.
API Haven Consulting focuses on the boundary between your identity provider, API gateway, and application code. Engagements stay bounded: we document what is broken, what is risky, and what to change first — without selling a platform license or open-ended staff augmentation.
How a typical security engagement runs
Surface mapping
Inventory public and internal routes, auth middleware order, and which clients use which grant types (authorization code, client credentials, mTLS).
Threat-aligned review
Walk through token leakage paths, broken object-level authorization, and misconfigured CORS or cookie flags on auth endpoints.
Remediation plan
Prioritized backlog with concrete code or configuration changes, plus test cases your CI can run against staging.
Advisory checkpoints
Optional follow-on calls while your engineers implement — we answer edge cases on PKCE, rotation, and partner onboarding.
Scoped project work and ongoing technical advisory — not a subscription dashboard. You keep your stack; we strengthen how it authenticates callers.
Code-level authentication reality
Reviews include reading middleware, gateway rules, and test harnesses — not slide decks alone. We trace a bearer token from issuance through validation and into database row filters.
Ways teams engage us
Design workshop
Working sessions to shape token lifetimes, scope models, and service accounts before greenfield services launch.
Technical advisory block
Pre-paid hours for questions as you roll out mTLS, rotate signing keys, or onboard B2B partners.
Questions we hear before signing
Do you run penetration tests?
We focus on architecture and implementation review. If you need formal pentesting, we can help you scope requirements for a specialist firm.
Which stacks do you work with?
Common stacks include Kong, Envoy, AWS API Gateway, Keycloak, Auth0, and custom JWT middleware in Node, Go, Java, or .NET — assessed case by case.
Who is this not for?
Teams looking for 24/7 SOC coverage or a managed WAF contract should speak with an MSSP. We are consultants on authentication design and API hardening.
