API Security Testing
Manual REST and GraphQL API testing against the OWASP API Top 10, with focus on authorization flaws, authentication weaknesses, data exposure, injection, and resource abuse.
Protect the APIs that power your products, AI systems, and customer data with manual penetration testing built around the OWASP API Top 10. Vynox Security tests REST and GraphQL endpoints for authorization gaps, token weaknesses, injection paths, data exposure, and resource abuse, then delivers evidence-backed findings your engineers can reproduce, prioritize, and fix quickly.
Manual API security testing for REST, GraphQL, authentication, authorization, and data exposure risks.
Manual REST and GraphQL API testing against the OWASP API Top 10, with focus on authorization flaws, authentication weaknesses, data exposure, injection, and resource abuse.
Deep testing of REST endpoints, tokens, objects, parameters, and workflows to uncover BOLA, mass assignment, excessive data exposure, and business logic attack paths.
Focused assessment of GraphQL schemas, queries, mutations, access controls, introspection exposure, batching behavior, and authorization weaknesses across roles and tenants.
Vynox Security begins with a discovery call to understand your API architecture, authentication model, endpoint inventory, roles, environments, and testing constraints. The team confirms scope, access requirements, and whether REST, GraphQL, AI-connected, or compliance-sensitive APIs need priority.
Security-conscious teams trust Vynox Security to find exploitable gaps and accelerate remediation.
Vynox Security combines deep manual testing with clear reporting and fast remediation support.
Hand-exercised testing uncovers authorization, logic, and data exposure flaws automated scanners miss.

API pentesting is a manual security assessment of application programming interfaces, such as REST and GraphQL APIs. Testers interact with endpoints like an attacker would to find authorization flaws, weak authentication, excessive data exposure, injection issues, rate-limit bypasses, and business logic abuse. Vynox Security maps findings to OWASP API Top 10 and provides HTTP-level evidence, reproduction steps, and remediation guidance.
