API Security Assessment
Our API Security Assessment service helps businesses identify and address security weaknesses in their APIs before they can lead to unauthorized access, data exposure, or service disruption. We evaluate API security controls, authentication mechanisms, permissions, and data handling practices to help ensure that APIs communicate securely and expose only the information and functionality intended for authorized users.
We begin by reviewing API documentation, endpoint structures, authentication methods, access policies, and data flows within an agreed assessment scope. Through systematic testing and configuration reviews, we identify potential vulnerabilities and recommend improvements tailored to the application's architecture and security requirements.
Our assessment focuses on common API security risks, including broken object-level authorization, broken authentication, broken function-level authorization, excessive data exposure, improper input validation, and security misconfiguration. We also review rate limiting, error handling, sensitive information management, and protections against abuse of business workflows.
For REST APIs, we examine how endpoints handle authenticated and unauthenticated requests, whether users can access resources belonging to other accounts, and whether sensitive operations enforce appropriate permissions. We also review token handling, session security, request validation, pagination limits, and the consistency of authorization checks across endpoints.
Following the assessment, we provide a structured report documenting identified issues, supporting evidence, severity ratings, potential impact, and practical remediation recommendations. Where appropriate, we can also perform retesting to help verify that security fixes address the reported weaknesses.
Whether you are building a public REST API, a mobile application backend, an e-commerce platform, or a business integration service, our goal is to help protect API endpoints, safeguard sensitive data, and strengthen the overall security of your application.
All testing is conducted with explicit authorization and within a clearly defined scope, using controlled methods designed to minimize disruption to production systems.
