API Security Testing
APIs are where modern breaches happen: broken object-level authorisation, excessive data exposure, unauthenticated business flows — flaws browser-centric scanners never exercise. SigmaReview tests APIs as a first-class surface, not a by-product of web scanning.
Why API testing is its own discipline
The OWASP API Security Top 10 exists because API risk differs from web risk: BOLA/IDOR, broken function-level authorisation, mass assignment and unrestricted resource consumption need schema-aware, auth-aware testing.
Schema-driven coverage
Effective API testing starts from the contract — OpenAPI/Swagger definitions drive systematic coverage of every endpoint and method, including the deprecated ones still answering in production.
How SigmaReview runs it
Automated API scanning integrated with the same pipeline as SAST/DAST, findings consolidated into the single audit-ready picture, with senior testers exercising authorisation logic — the flaw class automation reliably misses.
Where API testing fits your compliance
PCI DSS 6.2.4 attack coverage and 11.4 penetration testing for API-driven payment flows; RBI/SEBI application-security expectations; the API inventory discipline your ISO 27001 asset management wants anyway.
FAQ
We already run DAST — do we need API testing?
Browser-driven DAST exercises what a browser renders; APIs behind mobile apps and integrations need schema-driven testing with per-role credentials to find authorisation flaws.
What do we need to provide?
API definitions (OpenAPI/Postman), test credentials for at least two privilege levels, and a safe environment — the setup conversation happens at onboarding.
Does it cover internal APIs?
Internal and partner APIs carry the same flaw classes and are testable the same way; scope follows your risk, not just your public surface.
