Overview

What Is API Security Testing?

API security testing is a specialized API security assessment that targets the application programming interfaces your organization exposes to partners, mobile applications, and third-party integrations and services. Our testers test REST, GraphQL, and SOAP API endpoints against the OWASP API Security Top 10 and advanced API attack scenarios to uncover vulnerabilities that traditional web application testing may miss. The result is a prioritized report detailing every weakness along with clear remediation guidance.

Why Do You Need It?

APIs handle the majority of your application traffic and often provide direct access to sensitive data and business logic. A single misconfigured endpoint can expose customer records, enable account takeover, or allow unauthorized transactions. Regular API security testing helps ensure your interfaces enforce proper authentication, authorization, and input validation — meeting compliance requirements such as PCI DSS, GDPR, and SOC 2 while protecting your revenue and reputation.

What We Test

Our API security assessment covers the full spectrum of API-specific security attack vectors aligned with the OWASP API Security Top 10.

Broken Object Level Authorization (BOLA) & BFLA
Authentication token security and session management
Rate limiting and resource consumption abuse protection
Injection attacks (SQL, NoSQL, command, GraphQL)
Mass assignment & excessive data exposure
Server-Side Request Forgery (SSRF)
API versioning & deprecated endpoint exposure
Business logic flaws in API workflows
Methodology

Our Methodology

API security testing is always authenticated: real user accounts per role are used so authorization can be checked, not just authentication. Any available OpenAPI, Swagger, Postman, or GraphQL schema is leveraged, and undocumented endpoints — often the source of the worst bugs — are actively hunted for.

Scoping & Credentials

The APIs in scope (public, partner, internal) are defined, any OpenAPI/Swagger or Postman collections are collected, and test accounts are set up for each user role. This ensures authorization is tested properly, not just authentication.

Process

Testing Lifecycle

Every API engagement follows the same end-to-end API security testing process — scoping the APIs and roles, discovering every endpoint (documented or not), systematically testing for OWASP API risks and business-logic bugs, proving real impact with clean proofs-of-concept, and delivering developer-ready fixes with a free retest after you ship them.
