API security testing

Protect your applications and data!

API security breaches can lead to the leakage of sensitive data, financial losses, and damage to your company’s reputation—especially if your interfaces are vulnerable to attacks.

Regular API security testing helps you identify and eliminate potential security weaknesses before they can be exploited, ensuring your APIs are resilient to attacks and compliant with security standards.

What is API security testing?

API security testing is the process of assessing the security of application interfaces to ensure their resilience against attacks. It involves a variety of tests that help identify vulnerabilities and protect sensitive data.

Why is regular testing important?

Regular testing is essential because new security vulnerabilities constantly emerge due to software updates, configuration changes, and evolving attack methods. This is especially important for companies that develop or use software products, web applications, mobile apps, and e-commerce platforms. We recommend conducting tests 2–4 times a year to ensure ongoing security.

What does API security testing include?

  1. Authentication and authorization
    We check whether your API has a proper authentication mechanism in place, ensuring that access rights are correctly managed.
  2. Input validation
    We test how input data is validated to prevent common vulnerabilities such as injection attacks.
  3. Encryption and data integrity
    We ensure that sensitive data transmitted through the API is properly encrypted using secure protocols.
  4. Rate limiting and throttling
    We verify that your API implements appropriate rate limiting and throttling techniques to prevent abuse or denial-of-service attacks.
  5. Error handling and logging
    We check that error messages returned by your API do not reveal sensitive information, and ensure that logging mechanisms are in place to track security incidents.
