API Security Testing helps organizations identify security risks within Application Programming Interfaces (APIs) that power modern applications and integrations. By assessing APIs for vulnerabilities, misconfigurations, and logic flaws, organizations can prevent unauthorized access, data exposure, and abuse of backend systems.
What is API Security Testing?
API Security Testing focuses on evaluating the security of REST, SOAP, and GraphQL APIs by analyzing authentication mechanisms, authorization logic, data validation, and business workflows. Unlike traditional application testing, API testing targets the backend logic that attackers often exploit directly.
This service is critical for applications that rely on microservices, third-party integrations, or mobile and web frontends.
What We Test?
- Authentication and authorization mechanisms
- Broken object level and function level authorization
- Input validation and injection vulnerabilities
- Rate limiting and abuse protection
- Business logic and workflow flaws
- Insecure data exposure
- API versioning and deprecated endpoints
- OWASP API Top 10 risks
Our approach:
We conduct API Security Testing using a combination of automated tools and in-depth manual testing to validate findings and uncover complex logic flaws. Our assessments are aligned with the OWASP API Security Top 10 and focus on real-world attack scenarios.
Each engagement prioritizes accuracy and actionable results, ensuring that identified issues can be effectively remediated by development and security teams.
Benefits of API Security Testing
- Reduced risk of unauthorized access and data breaches
- Improved protection of backend services
- Early identification of logic and authorization flaws
- Enhanced security for integrations and third-party consumers
- Alignment with modern API security best practices
What you get?
- Detailed API security assessment report
- Risk-ranked vulnerabilities with clear descriptions
- Proof-of-concept examples where applicable
- Actionable remediation recommendations
- Executive summary for stakeholders
- Optional validation testing after fixes
When to Perform API Security Testing?
- Before production deployment
- After major API changes or new endpoints
- For applications using microservices architectures
- When exposing APIs to external or third-party users
