Our Approach to Web Application Penetration Testing

Web application penetration testing is a comprehensive service that evaluates the security of your web applications from an attacker’s perspective. At Informer, we use a combination of automated and manual techniques to achieve maximum coverage and depth of pen testing. Our automated vulnerability discovery capability scans your web applications for common and emerging vulnerabilities, such as injection, cross-site scripting, broken authentication, and insecure deserialization. Our expert pen testers use their skills and experience to perform manual testing and exploit the vulnerabilities found by the automated tools.

How We Security Test Web Applications

Our web application security testing service follows a systematic process that covers the entire attack surface of your web application and provides you with actionable insights to reduce your security risk:

Web application mapping and analysis: We start by mapping and analyzing your web application’s structure, features, and components from both an unauthenticated and an authenticated perspective.

Attack vector discovery: We then identify and prioritize the potential attack vectors that could compromise your web application’s security.

Vulnerability identification and exploitation: We use various tools and techniques to test and exploit the vulnerabilities associated with each attack vector. We not only check for the OWASP Top 10, but also advise you on how to implement defence-in-depth strategies to harden your web application against future threats.

In-depth dynamic security testing with multiple user levels: We perform dynamic security testing with different user roles and privileges to gain more visibility and coverage of your web application’s functionality. This helps us discover and assess vulnerabilities that could lead to sensitive data exposure.

Instant Access to your Web App Pen Test Results

Our web app penetration testing service uses our SaaS platform to give you a quick and interactive security testing experience. You can fix vulnerabilities as soon as our testers discover them without waiting for the test to end. Use our Jira integration to create tickets automatically for your developers to resolve issues.

Each test comes with a summary that gives you a simple overview of the results. For each vulnerability discovered, you can access:

  • Detailed descriptions of the vulnerability 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 our platform so you can access detailed findings fast or export them in a PDF report. You can download reports in a number of formats at any time during or after the test.

Technical support and debrief sessions

Our web application penetration testing service does not end with delivering reports. Our commitment extends to offering comprehensive debrief sessions with our expert penetration testing team. During these sessions, you’ll have the opportunity to discuss findings, ask questions, and seek advice. Whether you’re part of the security, IT, or development teams, we’re here to empower you with actionable insights.

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.
