API Penetration Testing
We test your API implementations for flaws in authentication, authorization, and data handling, protecting sensitive information exchanged between systems.
What is API Penetration Testing?
API penetration testing is a security assessment of your REST, GraphQL, or gRPC APIs that identifies vulnerabilities in authentication, authorization (BOLA/BFLA), rate limiting, data exposure, and business logic (the attack surface that automated scanners miss).
Testing Checklist
Every engagement covers these critical security areas.
Testing Methodology
A structured, repeatable process that ensures thorough coverage and actionable results.
API Discovery & Documentation
Map all API endpoints, methods, parameters, and authentication mechanisms through documentation review and active discovery.
Authentication & Token Testing
Test OAuth flows, JWT implementation, API keys, and token lifecycle for weaknesses in issuance, validation, and revocation.
Authorization Testing (BOLA/BFLA)
Test for Broken Object Level Authorization and Broken Function Level Authorization across all endpoints and user roles.
Input Validation & Injection
Test all parameters for injection vulnerabilities, mass assignment, and data type manipulation across REST, GraphQL, and SOAP endpoints.
Rate Limiting & Abuse
Verify rate limiting implementation, resource consumption limits, and protection against automated abuse and enumeration attacks.
Reporting & Remediation
Deliver findings with API-specific remediation guidance, including code examples and security header recommendations.
Framework Alignment
Our methodology is aligned with industry-recognized security frameworks for thorough coverage and compliance readiness.

Frequently Asked Questions
What is API penetration testing?
API penetration testing is a security assessment of your REST, GraphQL, or gRPC APIs that identifies vulnerabilities in authentication, authorization (BOLA/BFLA), rate limiting, data exposure, and business logic (the attack surface that automated scanners miss).
Do you test GraphQL and gRPC APIs?
Yes. We test REST, GraphQL, and gRPC APIs including introspection attacks, query depth abuse, field-level authorization, and schema-specific vulnerabilities.
