API Security Testing
Safeguard the backbone of your digital architecture. Our specialized API security audits evaluate RESTful, GraphQL, SOAP, and microservice APIs to uncover broken authorization, data exposure, and logic flaws before malicious actors exploit them.
Why API Security Testing Is Essential
APIs transfer vast volumes of sensitive data between clients and backend microservices, creating high-value targets for modern cyberattacks.
Uncover BOLA & BFLA Flaws
Detect Broken Object Level Authorization (BOLA) and Broken Function Level Authorization (BFLA)—the most prevalent and dangerous API vulnerabilities.
Microservice Interconnection
Ensure secure trust boundaries across internal and third-party microservices, preventing lateral movement and unauthorized backend data calls.
Prevent Data Over-Exposure
Identify raw JSON response payloads that leak excessive data properties, sensitive records, or unhashed internal IDs to unauthorized consumers.
Vulnerabilities We Uncover
Fully aligned with the OWASP Top 10 API Security standard.
Our API Security Testing Methodology
A structured, rigorous manual and automated testing process tailored for complex API ecosystems.
Endpoint Discovery & Schema Mapping
We analyze OpenAPI/Swagger documents, Postman collections, and WSDL schemas to map all REST, GraphQL, and SOAP endpoints alongside authentication methods.
Authentication & Token Analysis
We evaluate OAuth 2.0 implementation, JWT signature validations, session expiration, token revocation, and multi-factor authentication (MFA) enforcement.
Authorization & Input Fuzzing
Engineers perform cross-user token swapping, parameter tampering, batch payload injections, rate-limit testing, and deep authorization checks across endpoints.
Reporting & Remediation Verification
We provide a comprehensive report detailing CVSS-scored vulnerabilities, clear reproduction steps, code-level remediation guidance, and a complimentary re-test.
