API Pentesting
Our API penetration testing identifies vulnerabilities in your application's endpoints. We tailor each assessment to your architecture for the best coverage.
The Challenge
APIs expose direct paths to data and logic; broken authorization and object-level access flaws are among the most common and damaging issues.
How We Help
We test REST, GraphQL and other APIs against the OWASP API Security Top 10, focusing on authorization, data exposure and abuse of business logic.
- Authentication & token testing
- Broken object-level authorization (BOLA/IDOR)
- Broken function-level authorization
- Excessive data exposure
- Rate limiting & resource abuse
- Input validation & injection
- GraphQL and REST-specific testing
- Prioritized report & remediation guidance
Typical project examples
Authorization testing across a multi-tenant API
GraphQL schema and resolver abuse testing
Mobile app backend API assessment
Frequently asked questions
Do you test GraphQL as well as REST?
Yes — we cover REST, GraphQL and similar interfaces, adapting techniques to each.
Do you need our API documentation?
Documentation and example requests speed things up and improve coverage, but we can also work from discovery.
What standard do you use?
The OWASP API Security Top 10, extended with manual authorization and business-logic testing.
