VAPT & Security Testing
API Security Testing
APIs expose business logic directly. We test them for the weaknesses attackers exploit most.
Overview
What is API Security Testing?
API security testing covers REST, GraphQL and other APIs: authentication and token handling, object- and function-level authorization, excessive data exposure, rate limiting, input validation and business-logic abuse — based on API specifications and real traffic.
