[ api security ]

Every endpoint. Every token. Tested continuously.

Discovers REST, GraphQL, SOAP and microservice endpoints, then attacks authentication, authorization and business logic.

[ what the agent does ]

Four passes over every API, end to end.

01

Discovery & Documentation

Identifies all endpoints, parameters and auth mechanisms.

02

Authentication & Authorization

Tests token handling and access controls.

03

Data Validation & Business Logic

Hunts injection and logic flaws.

04

Security Controls Assessment

Rate limiting, encryption, logging.

[ sample finding ]

What lands in your queue.

High Endpoint GET /api/v1/users/{userId}

Broken Object Level Authorization

The API endpoint allows users to access other users' data by manipulating the userId parameter without proper authorization checks.

[ recommendation ]

Implement proper authorization checks to ensure users can only access their own data or data they have explicit permission to access.
