API Pentest Authorization • tenant isolation • exploit proof
We test REST, GraphQL, mobile backend, partner, and internal APIs for broken object-level authorization, token issues, rate-limit gaps, tenant isolation flaws, and sensitive endpoint abuse.
APIs fail most often at access control, token handling, and trust boundaries.
Object-level access, role checks, cross-tenant boundaries, and admin-only paths.
JWTs, refresh tokens, API keys, SSO integrations, and scope handling.
Rate limits, enumeration resistance, bulk data access, and unsafe admin functions.
Tight scoping, safe testing, and findings your engineering team can act on immediately.
Step 01
Define API targets, auth methods, docs, accounts, and environment constraints.
Step 02
Test authorization, token handling, data access, and abuse controls with evidence.
Step 03
Translate technical flaws into impact, priority, and remediation steps.
Step 04
Verify critical fixes once your team ships changes.
A few common questions about API penetration testing.
API testing covers authentication, authorization, object-level access control, token scope, rate limits, data exposure, sensitive endpoints, and exploit validation across REST, GraphQL, and internal services.
Yes. Multi-tenant APIs are a common focus area. Testing typically includes tenant isolation, IDOR risks, access-control boundaries, and privilege escalation paths.
Yes. API testing can be scoped as a standalone engagement or included inside a broader penetration test or VAPT engagement.
