API penetration testing
Penetration testing for APIs
Your API is the real application behind your website and mobile app. We test it directly, aligned to the OWASP API Security Top 10.

What we test
- Broken object-level authorisation — changing an ID to reach someone else’s record
- Authentication, token handling and expiry
- Responses that return more data than the screen shows
- Mass assignment — setting fields such as role or price you shouldn’t control
- Rate limiting and resource exhaustion
- GraphQL introspection and query depth
What helps
An API description (OpenAPI/Swagger or a GraphQL schema) and test accounts for each role make testing faster and more thorough.
