Web Applications Penetration Testing

Web Application penetration testing could use combination of automated and manual methods in order to exploit discovered vulnerabilities, security flaws and threads in web applications. In other words the testing simulates the activities of a malicious hacker by representing the methods and tools which the hacker would use. Security vulnerabilities could be discovered in front end and back end systems, databases, programming code, authentication mechanisms and more. After that the test discovers and prioritizes the discovered vulnerabilities. After all the test represents options for remediation of the discovered vulnerabilities. In addition the web application penetration test also examines all communication channels and APIs.
In cases when mobile application is also present, mobile application penetration test might also be required.


  • Introduction and Objectives
  • Information Gathering
  • Configuration and Deployment Management Testing
  • Identity Management Testing
  • Authentication Testing
  • Authorization Testing
  • Session Management Testing
  • Input Validation Testing
  • Error Handling
  • Cryptography
  • Business Logic Testing
  • Client Side Testing

White box vs Black box testing

Black Box Testing

It requires no knowledge of internal paths, structures, or implementation of the tested software.

Gray Box Testing

In Gray Box testing a tester attempts to find security bugs with incomplete information of the software product’s inner code structure.

White Box Testing

White Box testing provides the tester with knowledge of the application structure and functionality. In other words the purpose of the white box testing is to test the application from developer’s point of view.


Penetration testing report covers the activities, performed during the penetration testing. Therefore the report represents the discovered vulnerabilities in two parts:

Management part

  • A general description of the security of the systems.
  • The impact that the discovered vulnerabilities might have on the information security.
  • Required security measures to address the problems.

Technical part

  • Definition and classification of risk levels, used to classify the detected vulnerabilities.
  • Description of the information gathering phase for identifying information systems.
  • Results of scanning and exploitation of detected vulnerabilities, description, impact, criticality, affected asset, proof of concept, vulnerability replication method, and remediation steps.


  • Your developers might be good in the development of functional, fast and scalable applications, but security is another topic. Pentest is recommended for those without Internal pentesting team.
  • Penetration tests are often required by mandates like PCIDSS, HIPAA/HITECH and FINRA.
  • Web application penetration testing is especially valuable if your business is dependent on your application, it holds your clients private data or it as options for onlie payments and orders.
  • Penetration testing can help you comply with the technical requirements of GDPR.

5 to 30 days for a single Web Application, depending on the complexity.

Our experts hold various certificates in the area, like CEH, OSCP, CCSA and more.

We can engage our partners to fix your vulnerabilities if you lack expertise. We avoid fixing them on our own due to conflict of interests.
