REST API VAPT
Auth, BOLA/BFLA, mass assignment, injection, and pagination abuse.
Services
API security testing for REST and GraphQL
Manual API penetration testing against the OWASP API Security Top 10 — broken object-level authorization, excessive data exposure, and business-logic abuse that scanners miss.
Overview
APIs carry your most sensitive data and are now the top finding category in our VAPT reports for SaaS clients. Automated scanners catch the easy issues; our testers chain low-severity flaws — an IDOR here, a verbose error there — into real data-exposure proofs.
You provide an OpenAPI spec, Postman collection, or test credentials; we return CVSS-rated findings with exact reproduction steps, plus a free retest of critical issues after you patch.
What we deliver
Services included
GraphQL assessments
Introspection, batching attacks, nested-query DoS, and field auth.
OpenAPI-driven fuzzing
Spec-based fuzzing for edge cases and parser differentials.
Mobile backend testing
API abuse via repackaged apps, token theft, and cert-pinning review.
Rate-limit & anti-abuse
Credential stuffing, enumeration, and scraping resistance review.
Remediation retest
Free retest of critical/high findings with evidence verification.

Frequently asked questions
An OpenAPI/Swagger spec or Postman collection, test credentials for two roles (to test authorization), and a staging environment. We can work without docs, but coverage is better with them.
APIs lack UI constraints, so testers focus on object-level authorization, excessive data exposure, mass assignment, and business-logic flows unique to your endpoints.
Yes — introspection control, query depth/cost analysis, batching abuse, and per-field authorization are standard checks.
Typically 1–3 weeks depending on endpoint count and roles. You get a scoping call and fixed quote before we start.
