Web Service Penetration Test

What is a Web Service Penetration Test?


Web service penetration testing is assessing the functions and methods of an Application Programming Interface (API), determining how they could be abused, and how authorisation and authentication mechanisms could be bypassed.

We perform a series of in-depth authenticated, unauthenticated, automated and manual runtime analysis of the web service and explore the target API for vulnerabilities that cannot be found by automated means, such as business logic flaws. For the best results, we develop custom test cases tailored to the target API context to probe the web service and find the faults before the bad guys do.

All of our web service security testing is benchmarked against the industry-recognised Open Web Application Security Project (OWASP) Application Security Verification Standard.


Did You Know?

  • Web applications are the intial target in 86% of security breaches.

  • 1 in 5 web application vulerabilities are considered to be of high severity

  • Out of 338 cases with confirmed breach data, 11.8 billion records were compromised. That's an average of almost 35 million records per breach!

  • Attacks on company web applications increased by 52% in 2019, with most attackers targeting financial and personally identifiable information.

  • In 2019, 16% of successful attacks resulted in full control of the underlying system hosting the application, with half allowing further attacks on the internal corporate network.

By building off industry-recognised testing standards, such as those developed by the Open Web Application Security Project (OWASP), we ensure that our assessments deliver the right balance of breadth and depth to allow you to feel confident about your application security.

Our Web Service Penetration Tests help identify weaknesses in your API development and deployment, and provide benefits including:

  • Verifying that sensitive information store in your application databases is not vulnerable to theft and is stored in a secure manner
  • Discovering vulnerabilities in the way that information is transferred between applications
  • Ensuring that your API is using strong authentication and session management controls
  • Analysing the difference in responses between a well-formed, expected request and one that has been tampered with
  • Discovering business logic flaws that could lead to the theft of sensitive data
