Web/API Application Testing


Web applications play a critical role in business success and are an attractive target for cybercriminals. Web application penetration testing proactively assesses applications to identify vulnerabilities that could lead to the loss of sensitive user and financial data.


Penteor’ methodology is based on industry best practice frameworks for penetration testing and application testing. Reference documents include OWASP Testing Guide, Open-Source Security Testing Methodology Manual (OSSTMM), vendor-specific security documents and our own experience with risk and technical testing. Our web application security testing team will help to identify vulnerabilities including:

Injection flaws
Authentication weaknesses
Poor session management
Broken access controls
Security misconfigurations
Database interaction errors
Input validation problems
Flaws in application logic

Our approach to web application security testing

Step one

Scoping - define any websites and applications in scope and develop an appropriate testing strategy.

Step two

Reconnaissance and intelligence gathering - using the latest intelligence gathering techniques to uncover security and technical information that could help consultants to understand the websited and applications.

Step three

Active testing and vulnerability analysis - using a combination of automated tools and manual testing, our consultants seek to identify security vulnerabilities and develop a strategy to exploit them.

Step four

Exploitation - after a vulnerability have been identified the consultant develop and execute a plan to exploit vulnerabilities in a safe way that avoids damage and disruption.

Step five

Reporting - once testing is complete, our consultants will document all findings and provide you prioritized guidance on how to address the identified vulnerabilities.


Frequently asked questions about Web Application testing

A web application penetration test is a type of ethical hacking that evaluates the architecture, design, and configuration of web applications. Testing is performed to identify cybersecurity risks that could lead to unauthorized access and/or data exposure.

Penteor's web application penetration testing is conducted by a team of certified professionals who have a deep understanding of the latest tactics and techniques used by attackers to compromise web applications.

The information needed for the scope of a web application security test typically includes the number and type of web applications to be tested, the number of static and dynamic pages, the number of input fields, and whether the test should be authenticated or unauthenticated (i.e., with known/unknown credentials).

Penetration testing for web applications requires not only knowledge of the latest web application security testing tools, but also a deep understanding of how to use them most effectively. To assess web application security, our consultants use several specialized tools. These range from specialized pen-testing platforms (such as Cobalt Strike, Metasploit Pro, and Kali Linux) to networking tools (such as Wireshark) to homegrown tools and exploits written using Python, Java, and PowerShell.

The time it takes a consultant to perform a web application penetration test depends on the scope of the test. Factors that affect the duration include the number and type of web applications being tested, and the number of static or dynamic pages and input fields.

After each web application security test, the ethical hacker(s) assigned to the test will produce a custom written report, detailing any weaknesses identified, associated risk levels, and recommended remedial actions.

The cost of a web application penetration test is based on the number of days it takes a consultant to complete the agreed scope of the job. To get a quote for a penetration test, your company will need to complete a questionnaire in advance, and Penteor's experts can assist you with this.
