API Security Testing
I assess REST and web APIs to identify security weaknesses that impact authentication, authorization, and sensitive data exposure. My testing focuses on validating real-world exploitability of API flaws that are commonly abused in modern applications.
Assessments are conducted in alignment with the OWASP API Security Top 10, combining manual testing techniques with industry-standard tools to uncover issues that automated testing alone may miss. Each engagement results in clear, actionable findings designed to help teams reduce risk and secure their APIs effectively.
