Web Application Penetration Testing

Web application penetration testing is a crucial process in the modern development lifecycle. It helps identify and fix vulnerabilities before they can be exploited. A web app pen test can identify and address any security flaws that exist, and make sure the web application is secure and does not disclose sensitive data or information.

Our approach to web application penetration testing

Web application coverage and depth of pen testing are accomplished by using Informer’s automated vulnerability discovery capability in combination with our expert pen testers. To give you a high level of assurance, our pen testers follow an in-depth methodology and use their experience to find a range of vulnerabilities.

How we security test web apps

Each web application testing phase builds upon the other that results in the full attack surface of the web application and gives you the information that you need to action and reduce your security risk:

  • Web application mapping and analysis
  • Attack vector discovery
  • Vulnerability identification and exploitation

Successful application security testing is dependent upon mapping the entire application’s functionality and touchpoints from an unauthenticated perspective and from an end user’s perspective.

Vulnerabilities are identified by exploiting them. We go beyond the OWASP Top 10 and advise on defence-in-depth web application approaches so that you can strengthen the application if a vulnerability was introduced.

In-depth dynamic security testing with multiple user levels gives us greater application visibility and coverage. This approach gives us access to wide-ranging functionality that could contain a variety of vulnerabilities that lead to sensitive information exposure.

Instant online reporting

Our web app penetration testing service is delivered through our SaaS platform for a faster and more dynamic security testing experience. You can start to remediate vulnerabilities as soon as our testers find them without having to wait for the test to be completed. Utilize our Jira integration to automate ticket creation for your developers to get to work on fixing issues.

A summary is provided for each test and gives you a non-technical overview of the results. For each vulnerability discovered, you can access:

  • Detailed descriptions of the finding with CVSS scores
  • Evidence detailing the location and parameters affected
  • Screenshots uploaded by our penetration testers
  • Remedial action and recommendations
  • References to more information if you need to dig deeper

Each test is stored separately in the platform so you can access detailed findings fast or create a PDF report. You can download reports in a number of formats at any time during or after the test.

Technical support

We go beyond providing reports by offering a comprehensive debrief session so our penetration testing team can talk about the findings. This is a great opportunity for you and your security, IT, and development teams to ask any questions or seek advice.

Frequently asked questions

If you have any further questions, get in touch with our friendly team.

How safe is my application while you're testing?

Your application and data will be safe. We would prefer to test using test accounts that can be destroyed after we’ve finished testing.

Can you test using different user privilege levels?

We would recommend that all user levels are tested depending on the size of the user base and the potential damage that could be caused.

Do I need to have a staging environment for testing?

We can test on your production environment for a realistic assessment or test on your staging environment to remove the potential for any disruption. Vulnerabilities discovered in staging can then be retested on the production application.

Is my customer data secure when you are testing?

This depends on the environment that we’re testing. If we are testing an application in production then there could be a risk to the data, but we don’t aim to affect any live information.

What is Web Application Penetration Testing?

Web application pen testing attempts to uncover security vulnerabilities stemming from insecure development practices in the design, coding, and publishing of web applications or a website.

What are the different types of penetration testing?

Common types of pen testing include:

Internal Network Penetration Testing

Pen testing focused on assets within the corporate or the organizational network.

External Network Penetration Testing

Pen testing focused on testing assets and infrastructure that is internet-facing.

Mobile Application Penetration Testing

A penetration testing process that focuses on mobile applications on Android and iOS operating systems to identify authentication, authorization, data leakage, and session handling issues.

Which type of Penetration Testing is best?

There are many penetration testing methodologies and services available.

The most common is vulnerability discovery and assessment.

Vulnerability discovery takes a variety of pen testing approaches to find the weaknesses in a system and identify potential threats.
