Definition
What is web application penetration testing?
Web application penetration testing services proactively assess applications to identify vulnerabilities, such as those that could lead to the loss of sensitive user and financial information. Web applications play a vital role in business success and are an attractive target for cybercriminals, so regular web app pen testing is essential.
Redscan is a CREST-certified web app pen testing company. Our expert team, which includes Certified Web Application Testers (CCT APP), are hugely experienced at performing web application penetration testing and website security testing and can help your organisation to identify and remediate a wide range of risks.
Vulnerabilities
Web application vulnerabilities
Redscan’s web application penetration testing service can be commissioned to assess both proprietary web applications developed in-house as well as those from third party vendors.
Testing includes assessing applications for vulnerabilities listed in the OWASP Top 10, the Open Web Application Security Project’s ten most critical application security risks. 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
Methodology
Our web application security testing methodology
Web application pen testing can be both authenticated and unauthenticated. The methodology below outlines how Redscan approaches a ‘blackbox’ unauthenticated assessment where few details are shared with the tester in advance of an assessment taking place.
Benefits
What are the benefits of web app penetration testing?
Web app penetration testing provides a proactive approach to assess web applications and uncover vulnerabilities that could lead to unauthorised access and data exposure. Pen testing can be used to assess the architecture, design, configuration and/or implementation of apps.
A web app pen test will look for critical risks in apps developed in-house or those from third party vendors, including injection flaws, authentication weaknesses, security misconfigurations and flaws in application logic.
Web app penetration testing enables companies to achieve key outcomes to enhance the overall security of their application. These include improving access control, developing strong authentication and session management controls, ensuring compliance and checking the configuration of firewalls.
Process
Process for web app pen testing
A web app penetration test includes key steps that are completed in a cyclic pattern until no more vulnerabilities are found. The process focuses on the environment and the setup process, aiming to replicate the techniques used by attackers. Following the scoping phase, the testing process begins with collecting information about the web app, mapping the network it is hosted by and investigating any potential points of attack. An extensive threat modelling exercise is conducted prior to attack execution, and the test will conclude with a custom report, listing vulnerabilities by severity and ease of execution, and providing prioritised remediation guidance.

Frequently asked questions about web app pen testing
- What is web application penetration testing?
-
A web application penetration test is a type of ethical hacking engagement designed to assess the architecture, design and configuration of web applications. Assessments are conducted to identify cyber security risks that could lead to unauthorised access and/or data exposure.
- Who performs a web application penetration test?
-
Redscan web application penetration testing is performed by a team of CREST CCT APP certified professionals that have a deep understanding of the latest tactics and techniques that adversaries use to compromise web applications.
- What information is needed to scope a web app pen test?
-
The information needed to help scope a web application security test typically includes the number and types of web applications to be tested, number of static and dynamic pages, number of input fields and whether the test will be authenticated or unauthenticated (where login credentials are unknown/known).
- Which web application security testing tools are used?
-
Penetration testing for web applications not only requires knowledge of the latest web application security testing tools but also a deep understanding of how to use them most effectively. To assess web app security, ethical hackers leverage a range of specialist tools. These range from specialist pen testing platforms (such as Cobalt Strike, Metasploit Pro and Kali Linux), to networking tools (such as Wireshark), and custom-developed tools and exploits written using Python, Java and PowerShell.
- How long does it take to perform a web application security test?
-
The time it takes an ethical hacker to complete a web application penetration test depends on the scope of the test. Factors influencing the duration include the number and type of web apps assessed, plus the number of static or dynamic pages and input fields.
- Is web app testing right for your business?
-
Web application pen testing can be highly beneficial for your business if you develop proprietary web applications in-house or use an app provided by third party vendors. It can help to reduce the financial and reputational costs of a security weakness being uncovered in your app after it’s gone to market or has been shared with your customers. While web application pen testing provides many advantages, your business may benefit from other types of security assessments. Depending on your organisation’s specific requirements, other types of assessments include mobile application security testing, agile pen testing, cloud penetration testing and scenario-based testing. A good offensive security provider should be able to advise you on the most appropriate choice of assessment for your organisation.
- What is the difference between web app testing and network penetration testing?
-
While web app pen testing focuses on identifying security vulnerabilities in applications, network penetration testing, also known as infrastructure penetration testing, aims to identify cyber security vulnerabilities that could be used to compromise on-premises and cloud environments. Unlike web app testing, which looks at the app environment and the setup process, network pen testing looks at potential issues inside and outside an organisation’s network perimeter.
- What is the difference between web app testing and vulnerability scanning?
-
Web app pen testing focuses specifically on identifying security vulnerabilities in web applications while vulnerability scanning is an automated approach that aims to provide a broader overview of potential security risks, looking at aspects areas such as networks, servers, routers, mobile devices, websites and network applications. As a subset of vulnerability assessments, automated vulnerability scans are run via commercial scanner services or platforms on network infrastructure or application components.
- What happens at the end of a web app pen test?
-
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.
- How much does a web application penetration test cost?
-
The cost of a web application penetration test is determined by the number of days it takes an ethical hacker to fulfil the agreed scope of the engagement. To receive a pen test quotation, your organisation will need to complete a pre-evaluation questionnaire, although Redscan’s experts can support you with this.
