API Security Assessment
Evaluates the security of REST/SOAP/GraphQL APIs for authentication weaknesses, improper authorization, data exposure, and logic flaws.
Overview
Why this assessment matters.
APIs are the backbone of modern applications but are often the weakest link. Our API Security Assessment focuses on the unique vulnerabilities associated with Application Programming Interfaces. We test for Broken Object Level Authorization (BOLA), Broken User Authentication, Excessive Data Exposure, Lack of Resources & Rate Limiting, and Mass Assignment. Whether you use REST, SOAP, or GraphQL, our experts analyze your API documentation and endpoints to ensure secure data exchange and prevent unauthorized access to backend systems.
Capabilities
What we evaluate
01
OWASP API Top 10
Focused testing on the specific top risks affecting APIs.
02
BOLA/IDOR Testing
Critical checks for unauthorized access to other users' data.
03
Rate Limiting & Throttling
Verifying controls to prevent abuse and denial of service.
Methodology
Assessment phases
A structured, repeatable methodology to ensure comprehensive coverage of the attack surface.
01 - Discovery
Identifying all API endpoints, including undocumented or "shadow" APIs.
02 - Analysis
Reviewing API documentation (Swagger/OpenAPI) and understanding expected behavior.
03 - Testing
Sending malformed requests and attempting to bypass auth/authz controls.
04 - Validation
Confirming the severity of findings and impact on the backend.

FAQ
Common questions
Do you test GraphQL APIs?
Yes, we have specialized methodologies for testing GraphQL specific vulnerabilities like introspection abuse and query depth.
Do I need properly documented APIs?
Documentation helps significantly, but we can also perform black-box testing by discovering endpoints through traffic analysis.
Can you test internal APIs?
Yes, via VPN or other secure access methods, we can assess internal-only APIs.
