API Security Testing
About API Security Testing
APIs connect applications, services, partners, and customers—and they frequently provide direct access to valuable business data and functionality. Our API Security Testing service evaluates whether those connections can be abused to access information or perform actions beyond what a legitimate user should be allowed to do.
What We Test
We assess REST, SOAP, GraphQL, and other business APIs, including authentication, authorization, data handling, user roles, exposed functions, error responses, and integrations with backend systems.
Key Security Areas
- Authentication and authorization
- User and role permissions
- Unauthorized data access
- Excessive data exposure
- Input validation
- API configuration
- Business logic
- Rate and usage controls
- Protection of sensitive information
Deliverables
The final report provides verified findings, affected API endpoints or functions, severity and business impact, supporting evidence, and practical remediation recommendations. Leadership receives an executive summary, while technical teams receive actionable information to support fixes.
Business Value / Outcome
API testing helps prevent unauthorized access to sensitive data and business functions while reducing the risk created by interconnected systems. It enables organizations to identify weaknesses in the underlying connections that power modern applications, integrations, and digital services.
Secure the connections behind your digital business—not just the applications customers can see.
