API Security Testing

API Security Testing — REST, GraphQL & Beyond

APIs are the biggest attack surface modern applications expose. Our researchers specialize in finding BOLA, injection, auth bypass, and business logic flaws that automated scanners miss.

Testing Approach

How We Test Your APIs

REST API Testing

Full endpoint enumeration, verb tampering, parameter fuzzing, and business logic analysis on REST APIs.

GraphQL Security

Introspection abuse, query depth attacks, batch query attacks, and authorization bypasses in GraphQL APIs.

Auth Flow Testing

OAuth 2.0 flows, JWT signature bypass, token refresh attacks, and session management weaknesses.

IDOR at Scale

Systematic testing of Insecure Direct Object References across all object types, user roles, and endpoints.

API Discovery

Uncovering undocumented, legacy, and shadow API endpoints that developers may have forgotten.

Rate Limit & DoS

Testing for rate limiting bypass, account lockout evasion, and API abuse that could cause denial of service.

Integration

Works With Your Stack

Our researchers can test any API regardless of the technology stack or documentation format.
