Overview

What is API Security Testing?

APIs are the backbone of modern applications, connecting systems and enabling data exchange. However, insecure APIs can expose sensitive data and critical business logic. Our API Security Testing identifies vulnerabilities such as broken authentication, data exposure, and improper access control to ensure secure and reliable integrations aligned with STQC and industry standards.
