Overview

What This Engagement Covers

A comprehensive assessment tailored to your environment.

Modern applications rely heavily on APIs, making them critical attack vectors. Our API penetration testing service identifies authentication flaws, authorization bypasses, injection vulnerabilities, and business logic issues specific to API implementations.

Our Process

What We Test & How

What We Test

We test REST APIs, GraphQL endpoints, SOAP services, microservices architectures, and third-party API integrations. Our assessment covers authentication mechanisms (OAuth, JWT, API keys), rate limiting, input validation, error handling, and API-specific vulnerabilities that traditional web testing misses.

Our Approach

Using specialized API testing tools and custom scripts, we map your API surface, analyze authentication flows, test authorization boundaries, and identify data exposure risks. We test for OWASP API Security Top 10 vulnerabilities and examine your API documentation for security gaps.
