API Security Testing
REST, GraphQL, gRPC, and SOAP endpoints tested against the OWASP API Security Top 10 — where modern breaches increasingly begin.
Overview
APIs expose your business logic directly, and they're often less protected than the UI in front of them. We test each endpoint for the access-control and data-exposure flaws that dominate API breaches, including the ones only visible when you understand how objects and permissions relate.
What we cover
The ground a typical engagement covers — always tailored to your scope.
Broken object-level authorization (BOLA/IDOR) and function-level authorization
Broken authentication, token handling, and JWT flaws
Excessive data exposure and mass assignment
Rate-limiting, resource consumption, and business-logic abuse
GraphQL introspection, batching, and injection
Improper inventory — shadow, deprecated, and undocumented endpoints
What every engagement delivers
Impact-rated findings
Every issue rated by real-world impact and mapped to OWASP & MITRE ATT&CK — not just a raw CVSS score.
Developer-ready fix guidance
Practical, specific remediation steps for each finding, written for the engineers who'll fix it.
