Comprehensive security testing of REST, GraphQL, SOAP, and gRPC APIs. We identify authentication flaws, data exposure risks, and business logic vulnerabilities in your API infrastructure.
Our API penetration testing covers all aspects of API security following OWASP API Security Top 10.
API pentest procurement guide
A useful API penetration test is defined by business objects, identities and trust boundaries—not only by endpoint count. During scoping, nCrypt maps user roles, tenant boundaries, partner integrations, machine identities and sensitive workflows so testing can exercise the authorization decisions that create the highest business impact. Active testing starts only after the customer approves the target list, test accounts, testing window and rules of engagement.
We test login, token issue and refresh, logout, password reset, MFA, API keys, OAuth/OIDC flows and service-to-service credentials. The objective is to determine whether a lower-trust identity can obtain or retain access beyond its intended role.
Testing covers BOLA/IDOR, broken function-level authorization, tenant isolation, administrative actions and workflow state changes. We use approved accounts representing different roles and tenants so cross-account results are reproducible.
We assess injection, mass assignment, unsafe file or URL handling, GraphQL query controls, pagination, rate limits and abuse of multi-step transactions. Testing is adapted to the API design rather than reduced to an automated OWASP checklist.
The scope can include public, mobile-backend, partner and webhook endpoints; REST, GraphQL, SOAP and gRPC interfaces; and documented or discovered versions. Undocumented endpoints are reported as attack-surface findings, not silently added to active scope.
