Web Application Penetration Testing Services we provide

Network Penetration Testing

To get an up-to-date assessment of vulnerabilities and threats to your network infrastructure, we simulate real-world attacks targeting common and less obvious system security aspects. Both internal and external checkups are performed by our best pen testing experts with years of experience in pen testing. 

Web Application Penetration Testing

At Relevant, we leverage a diverse number of solutions and testing approaches, such as the Open Source Security Testing Methodology Manual (OSSTMM), Penetration Testing Execution Standard (PTES), and Open Web Application Security Project (OWASP), which allow us to access all the security aspects of your web-based applications.

API Penetration Testing

To ensure your software product is resistant to any possible scenarios and tactics of various cyber attacks, our specialists can also provide a full checkup of the API’s functions/methods, how they could be abused, and how authorization and authentication could be bypassed.

Mobile Application Penetration Testing

To perform first-class pen testing for mobile, our experts apply a wide range of automated and manual testing to assess mobile app security on iOS and Android. In the process, we apply OWASP, eLearnSecurity Web Application Penetration Testing (eWPT) methodologies, as well as our proprietary approaches and checkups. 

Internal Network Penetration Testing

At internal pentest, our testers will conduct a series of attacks that could be carried out by a hacker who has already gained a foothold within your network and is searching for more benefit or damage to be performed within your systems, such as data disclosure, misuse, alteration or destruction, accessing the NPPI and many more.

Black Box and Gray Box Penetration Testing

Apart from the traditional white box testing, Relevant’s experts can perform the gray box testing, in which a pentester is given identifiers and passwords to assume the role of legitimate users of all privilege levels. Additionally, our pen testing professionals possess strong black box testing skills – external tests, similar to a real-world hacking attack.

FAQ

Which penetration testing methodology is applied to web applications?

To identify the possible vulnerabilities through pen testing, our security professionals perform multiple simulated attacks to see whether it’s possible to gain access to the app, which are mainly divided into two categories: internal and external penetration testing. 

The external approach implies analyzing the components accessible to hackers via the Internet, for instance, through web apps or websites, while internal penetration tests simulate a scenario in which cyber attackers gain an access to your app behind the firewall.

What's the first step in pen testing web applications?

To perform penetration testing on web applications, the first and most essential step is the test configuration. At this stage, developers define the scope and goals of the testing project. This will help to get a better idea of how to perform the tests, covering web architecture, API elements, general infrastructure information, and many more.

Why is web application penetration testing so important?

Web app penetration testing is essential to ensure your product is steady, secure, and resistant to possible attacks. Also, pen testing allows experts to conduct the infrastructure assessment, satisfy compliance requirements and confirm security policies, which are the key points for nearly any web application solution.

Does penetration testing break a system?

Penetration testing simulates the attacks to identify the risks of system intrusion, as well as detect the existing vulnerabilities in an app. This process does not cause a complete system outage, but there is always the potential for it to interfere with the system's performance. That is why it’s important to hire dedicated pen testing experts who can minimize the negative impacts and successfully resolve any possible issues. 

What is the most common method of penetration testing?

The most commonly applied pentest method is network testing, according to which the testers conduct internal and external network exploitation. 

Other popular methods which help to identify and fix security weaknesses are web application penetration testing, wireless pen testing, social engineering pentest, and physical penetration testing.
