API Security Testing
Comprehensive security assessment of Application Programming Interfaces to identify vulnerabilities and ensure secure API implementations across your digital ecosystem.
Overview
API Security Testing
APIs form the backbone of modern digital applications and services, making their security critical for protecting data and business operations. Our API security testing evaluates REST, SOAP, GraphQL, and other API implementations to identify vulnerabilities in authentication, authorization, data validation, and business logic. We assess API security across the entire lifecycle from design through deployment and maintenance while testing for OWASP API Top 10 vulnerabilities and industry-specific security risks.
Methodology
Our API security testing follows industry-standard methodologies including OWASP API Security Testing Guide, NIST API Security guidelines, and API-specific penetration testing frameworks to ensure comprehensive coverage of API vulnerabilities and security weaknesses.
Benefits
- Identify API-specific vulnerabilities before attackers exploit them
- Protect sensitive data transmitted through API interfaces
- Ensure compliance with API security standards and regulations
- Validate effectiveness of API security controls and implementations
- Reduce risk of data breaches through compromised APIs
- Build stakeholder confidence in API security and reliability
API Discovery & Documentation Analysis
Involves comprehensive identification of all API endpoints, analysis of API documentation, and mapping of API functionality to understand the complete API attack surface and potential security risks.
Authentication & Authorization Testing
Encompasses thorough testing of API authentication mechanisms, token validation, session management, and authorization controls to identify bypass opportunities and privilege escalation vulnerabilities.
Data Validation & Business Logic Assessment
Includes detailed evaluation of input validation, output encoding, rate limiting, and business logic implementation to identify injection vulnerabilities and logic flaws.

Our Approach
API Endpoint Discovery
We conduct systematic discovery of all API endpoints including public, private, and undocumented APIs to establish complete visibility of the API attack surface and potential entry points.
Authentication Mechanism Testing
We thoroughly test API authentication including OAuth, JWT tokens, API keys, and other authentication methods to identify weaknesses in credential validation and session management.
Authorization Control Assessment
We evaluate API authorization controls including role-based access, resource-level permissions, and privilege escalation opportunities to identify unauthorized access vulnerabilities.
Input Validation Testing
We conduct comprehensive input validation testing including SQL injection, NoSQL injection, command injection, and other injection vulnerabilities across all API parameters and data inputs.
Rate Limiting Evaluation
We assess API rate limiting and throttling mechanisms to identify potential denial-of-service vulnerabilities and abuse scenarios that could impact API availability.
Error Handling Analysis
We analyze API error handling mechanisms to identify information disclosure vulnerabilities and improper error message exposures that could aid attackers.
Data Exposure Assessment
We evaluate API data exposure including sensitive information leakage, excessive data exposure, and inadequate data filtering to identify privacy and security risks.
Business Logic Testing
We test API-specific business logic including transaction manipulation, workflow bypass, and process exploitation to identify logic-based vulnerabilities.
Integration Security Review
We assess API integration security including third-party API security, microservices communication, and inter-service authentication to identify integration vulnerabilities.
Comprehensive Documentation
We provide detailed API security reports with vulnerability descriptions, exploitation scenarios, risk assessments, and specific remediation guidance for secure API development.
