Standard security tools view APIs as if they are standard Web pages and do not consider the essential logic flaws that constitute modern breaches. Secure Arcane stands out from the rest by offering API penetration testing services that are focused on Business Logic Validation. We don’t just fuzz parameters and know it is about the relationship between your data objects. Our experts manually create complex requests to see if authorization rules can stand up to the pressure – making sure that a “read-only” user can never cause a “delete” function. This logic-based approach is essential for ensuring true security. A scanner interprets a “200 OK” response as a success, and we check if the response contained data that it shouldn’t have. We carefully examine your token processing, role definitions and data filtering to reveal the subtle holes in the automated tools. Whether you are using GraphQL or traditional REST, our API penetration testing service gives you the granular, developer-ready insights necessary to close these dangerous loopholes and harden your backend against targeted attacks.
