API penetration testing

Test the interfaces your mobile and partner apps trust—authn/authz, object-level access, and business-logic abuse on REST or GraphQL.

Scope

Documented and discoverable API endpoints in scope: authentication and token handling, broken object/function level authorization, mass assignment, rate-limit bypasses, injection into parameters, and sensitive data exposure in responses. MCP/tool APIs can be included when access is provided—or via /ai-security.

Method

Contract/schema-aware testing plus manual abuse cases. CREST-aligned methodology; exploit validation before rating. Our testers hold OSCP and CREST certifications.

Deliverables

Endpoint-oriented findings with request/response evidence, remediation guidance, optional retest. Strong fit before SOC 2 security reviews.

Common questions

Helpful, not mandatory—discovery included in scope time.

Yes when in scope.

Only systems you authorize.

Common combo — also /pentesting/mobile.
