API Security Testing
Service Overview
APIs are the backbone of modern applications and a prime target for attackers. Our API Security Testing service uncovers vulnerabilities in REST, SOAP, GraphQL, and other APIs to ensure your backend services are secure, compliant, and hardened against exploitation. We simulate real-world abuse cases to identify broken authentication, excessive data exposure, injection flaws, and business logic vulnerabilities before attackers do.

What Is API Security Testing?
API Security Testing is a comprehensive security evaluation of your application's Application Programming Interfaces (APIs). This includes validating how clients interact with services, how authentication and access control are enforced, and how data flows through endpoints. We test for both technical flaws and logical abuse scenarios ensuring your APIs are not just functional, but resilient against modern threat vectors.
What Do We Test?
We perform exhaustive testing across key API security risks, including
Broken Object Level Authorization (BOLA)
Insecure direct object references
Broken Authentication
Token flaws, session handling, brute force
Excessive Data Exposure
Leaking sensitive fields via APIs
Lack of Rate Limiting
Abuse of login, search, or transaction endpoints
Mass Assignment & Parameter Tampering
Over-posting data to update internal fields
Injection Attacks
SQL, command, XML, NoSQL
Improper Assets Management
Exposed staging/debug APIs
Security Misconfigurations
Verb tampering, CORS misconfigs, header issues
Our Testing Process
We follow a proven methodology to ensure nothing gets overlooked
Define Scope

Key Benefits
Why Our API Security Testing Delivers Real Impact
Comprehensive OWASP API Top 10 Coverage
We go beyond surface-level scans to identify complex API-specific threats and compliance risks.
Protection Against Modern API Threats
Detects issues like BOLA, mass assignment, and insecure tokens before they’re exploited in the wild.
Secure Multi-Role Access
We validate API behavior for different roles ensuring privilege boundaries are enforced properly across users, admins, and third parties.
Logic Abuse Identification
Catch flaws like business rule bypasses, pricing manipulation, or resource misuse that automation misses.
Cryptography & Token Validation
We evaluate your use of JWTs, OAuth, HMACs, and encryption to ensure your data and sessions are secure.
Scalable & Future-Proof
Whether you're building an internal microservice or a public developer platform, our methodology adapts to your API’s structure and growth.
