Comprehensive security assessment for REST, GraphQL, and SOAP APIs — protecting the interfaces that power your applications from exploitation and data breaches.
API penetration testing is a comprehensive security assessment that simulates real-world attacks against your application programming interfaces. Our experts combine automated tools with manual testing techniques to identify vulnerabilities in REST, GraphQL, SOAP, and other API architectures that could be exploited by attackers.
We go beyond automated scanners to test authentication mechanisms, authorization controls, business logic, and complex attack chains that automated tools miss. Our methodology covers the OWASP API Security Top 10 and extends to advanced vulnerabilities specific to your API architecture.
From public APIs to internal microservices, we adapt our testing approach to your technology stack and business requirements.
Comprehensive coverage of OWASP API Security Top 10 and beyond.
Weak API key management, JWT token manipulation, OAuth2 implementation flaws, and authentication bypass vulnerabilities.
Insecure direct object references (IDOR), privilege escalation, and object-level authorization flaws in API endpoints.
APIs returning more data than necessary, PII leakage, and improper filtering exposing confidential data.
Missing rate limiting, resource exhaustion attacks, and denial of service vulnerabilities impacting API availability.
SQL injection, NoSQL injection, command injection, and XML injection through API parameters and request bodies.
Binding client-provided data to internal objects without proper filtering, allowing unauthorized property modification.
CORS issues, insecure HTTP methods, missing security headers, and improper API versioning.
Race conditions, workflow bypasses, pricing manipulation, and state management issues automated tools miss.
Inadequate API activity logging, missing security event monitoring, and poor audit trails.
A comprehensive approach combining automated scanning with expert manual testing.
Discovering all API endpoints, methods, parameters, and authentication mechanisms to build a complete API inventory.
Analyzing OAuth2, JWT, API keys, and custom implementations for token manipulation and authentication bypass.
Testing access controls across all endpoints and user roles, identifying IDOR and privilege escalation paths.
Comprehensive fuzzing of API parameters, headers, and request bodies for injection and parameter tampering issues.
Manual testing of API workflows, rate limiting, and business rules to identify flaws automated tools cannot detect.
Detailed documentation with proof-of-concept API requests, risk ratings, and specific remediation recommendations.
Protecting your applications and data from API-based attacks.
APIs often handle your most sensitive data. Identify vulnerabilities exposing customer, financial, and proprietary data.
APIs power payments, subscriptions, and integrations. Prevent financial fraud and service abuse from API vulnerabilities.
Satisfy regulatory requirements including PCI DSS, GDPR, HIPAA, and SOC 2 that mandate API security assessments.
Deploy new API features confidently, support partner integrations securely, and scale without introducing vulnerabilities.
Assess security of external APIs you consume and ensure partner integrations don't introduce vulnerabilities.
Build security into your API development lifecycle and establish baselines for future deployments.
Comprehensive reporting and actionable remediation guidance.
High-level overview of API security posture, critical findings, and strategic recommendations.
Detailed vulnerability documentation with CVSS scores, OWASP API mapping, and exploitation scenarios.
Step-by-step reproduction with actual API requests, curl commands, and Postman collections.
Specific fixes with secure code examples and best practices aligned with OWASP API Security standards.
Optional sessions covering secure API design and how to prevent similar issues in future development.
Verification testing after remediation to ensure vulnerabilities are properly fixed.
Identify and fix API security vulnerabilities before attackers can exploit them with comprehensive API penetration testing.
