APIs expose your business logic and data directly. A single broken authorisation check can leak every customer record.
We test REST, GraphQL and SOAP APIs against the OWASP API Security Top 10, with deep manual testing of object-level and function-level authorisation.
Objectives
- Detect broken object- and function-level authorisation
- Identify excessive data exposure and mass assignment
- Assess authentication, token handling and rate limiting
- Find injection and server-side request forgery issues
Methodology
01
Inventory
- Review API documentation, collections and schemas
- Map endpoints, roles and data sensitivity
02
Test
- Authorisation testing across users, roles and tenants
- Input validation, injection and SSRF testing
- Rate limiting and abuse-case testing
03
Report & retest
- Findings with sample requests and fixes
- Verification of remediated issues
