API Pentesting

APIs are the backbone of modern applications, enabling seamless communication between services, systems, and users. But this convenience comes with risk — APIs often expose large portions of an application’s logic and data, making them a prime target for attackers. Our API penetration testing service identifies weaknesses in authentication, authorization, and data handling that could allow unauthorized access, data leakage, or service disruption.

We take a comprehensive approach, assessing REST, GraphQL, and SOAP endpoints using both manual testing and automated fuzzing to uncover hidden vulnerabilities. From broken object-level and function-level authorization to improper rate limiting, injection flaws, and verbose error messages, we replicate real-world attack techniques to reveal how your APIs could be exploited. Our testing is aligned with the OWASP API Security Top 10 (2023) to ensure industry-standard coverage, helping you secure your API ecosystem before attackers can exploit it.
