How We Deliver Web Application Penetration Testing Services

Here are the stages of our web app pentesting service you will encounter while working with us as your web app pen test provider.

Step 1. Scoping and Information Gathering

Our web app pen test starts with a clear definition of the engagement scope. Our security experts identify the web applications, services and critical assets to be tested and the compliance mandates that will guide the test. In this phase, we outline the test objectives and gather the necessary information about third-party vendors, network infrastructure, and in-house-developed apps.

Step 2. Vulnerability Mapping

Our penetration testers map out potential vulnerabilities that might compromise business operations by using both automated and manual techniques. We identify security flaws through comprehensive vulnerability scanning, followed by checking for injection flaws, authentication weaknesses and security misconfigurations.

Step 3. Exploitation and Risk Validation

We simulate an attack in a real-world scenario via application logic testing and remote code execution among our methods. This offensive security approach by our pentesters confirms whether certain issues can actually blow up as critical vulnerabilities.

Step 4. Reporting and Remediation Guidance

The discoveries we make are compiled into a report describing vulnerabilities and app security issues based on their criticality, likelihood of exploitation and potential impact. A clear remediation guidance is also included to help the development teams resolve security weaknesses as fast as possible.

Step 5. Retest and Follow-up Support

After fixing, we retest the identified vulnerabilities to ensure they are patched. Our web application pen testing company offers recurring pentesting web services to keep your security team ahead of the newly emerging threats. We will further engage with you to keep your applications secure throughout the software development lifecycle.

Frequently asked questions

What is web application penetration testing?

Web application penetration testing systematically uncovers vulnerabilities in in-house, outsourced or third-party-vendor web applications. It is used to test for vulnerabilities in application logic, authentication and memory — areas that may be used by threat actors to gain access to a client’s web application.

What is the difference between web app testing and network penetration testing?

Web app testing is used by a web app pen test company to examine the data flow and unique features of web apps, such as login or APIs. Network penetration testing, on the other hand, is used to get a broader view of network infrastructure and connected systems.  

Who performs web application penetration tests?

These assessments are performed by professional penetration testers. Our security experts at Astro are ex-NASA cybersecurity professionals who apply cutting-edge techniques to uncover vulnerabilities in your attack surface. By applying methodologies of offensive security and using extensive experience in application penetration, we help you manage security risks, fortify business operations and protect valuable assets.

Which tools are used to perform web application security testing?

Our pen testers combine automated tools with manual approaches for maximum coverage. Our best-in-class toolset and custom scripts identify injection flaws and remote code execution possibilities, while manual analysis then validates critical vulnerabilities to provide your security team with the remediation guidance needed to address security weaknesses at their root cause.

How long does a web application security test take?

This timeline depends on the complexity of the application, the number of endpoints, and integrations with third-party vendors. Usually, the projects take any time from some days to weeks or so. Frequent test scheduling means that teams are able to keep up with critical risks and comply with set mandates.

How often should a web application be tested?

In a dynamic environment, testing should be done more frequently. Most businesses test quarterly, or after every significant update to find emerging threats. With a company like Astro, you get ongoing support to overcome vulnerabilities and keep pace with ever-evolving risks in the software development lifecycle.

Can web application penetration testing disrupt ongoing business operations?

Yes, it can, but minimizing this disruption is our task. Working in close coordination with your security team, we find optimal test windows and design scenarios to reduce risk as much as possible to the production system. Website pentest services hold your environment stable using thoughtful planning and progressive testing, giving your development teams room to iteratively operate while ensuring you address key vulnerabilities quickly.
