What is a Web Application Penetration Test?

Web application penetration testing is the process of safely simulating cyberattacks on a web application to find and fix security vulnerabilities before attackers can exploit them. Web application penetration testing services allow you to identify and fix issues before they can be exploited, providing your organization with protection against cyberattacks.

Rootshell Security’s Web Application Penetration Testing services assess your applications for issues listed in the Open Web Application Security Project (OWASP) testing guide; these are industry-recognised guidelines for web app security. We then safely utilise the same techniques as real-world threat actors to establish how vulnerabilities could be exploited.

Our CREST-certified penetration testers provide expert guidance throughout. You will receive the support you need to successfully fix issues as quickly and effectively as possible to keep your web applications protected.

The Benefits of Application Penetration Testing Services

Web application penetration testing is a proactive way to identify security flaws that could lead to unauthorised access or data breaches. It evaluates an app’s architecture, design, configuration, and implementation.

Year-round protection
Prepare for a real-world attack

Web applications are popular targets for threat actors; penetration tests are one of the most effective ways to improve and maintain their security. By emulating the tactics, techniques, and procedures used by threat actors, our penetration testing services truly put your web application security to the test.

Uncover critical vulnerabilities
Uncover critical vulnerabilities

As the risk of cyber attacks continues to increase, it’s crucial you have complete visibility of your organization’s vulnerabilities. Our web application penetration testing services will identify any vulnerabilities within your applications, from low to high risk, so you can take action.

Effectively remediate risk
Protect Sensitive Data

Sensitive data is a prime target for cybercriminals. Web application penetration testing helps you find and fix vulnerabilities that could be exploited to gain unauthorised access to information such as customer details, login credentials, financial records, and proprietary business data.

Comply with security standards
Comply with Security Standards

Many regulations (like GDPR, PCI DSS, and ISO 27001) require regular security testing. Pen testing helps demonstrate due diligence and supports compliance efforts. Our CREST-certified penetration tests will make sure that your organization is compliant.

Recognized industry leader in Cloud Penetration Testing

Process for Web App Pen Testing

A web app penetration test follows a repeatable cycle to identify and exploit vulnerabilities until none remain. After scoping, the process begins with gathering information, mapping the hosting environment, and identifying attack points. Threat modelling is carried out to simulate real-world techniques. The test concludes with a tailored report outlining vulnerabilities by severity and providing prioritised remediation advice.

01

Scoping

We work closely with your organization to understand and agree on the complexity of your requirements. This gives us the opportunity to discuss any prerequisites, such as test accounts, authorisation, and escalation processes. All scoping, including exchanging information, is conducted securely within the Rootshell Platform.

02

Pen testing

We assess your web applications against industry-standard OWASP guidelines to identify potential vulnerabilities. Our testing simulates a real-world attack by adopting the perspective of an unauthenticated and uninformed attacker, aiming to gain unauthorised access to sensitive application data or internal systems.

03

Reporting

We provide you with a clear and extensive pen test reporting, detailing all our findings from your web application penetration test. The report provides you with a clear understanding of any areas of risk or vulnerability and will form the basis of your remediation process.

04

Review

Once your penetration test is complete and you have reviewed your report, you can discuss all aspects of it with your consultant. We offer expert post-pen test support and guidance on web application remediation activities.

05

Free re-test

We are passionate about our cybersecurity testing and it’s our firm belief that delivering a report of vulnerabilities should not complete a penetration test. Following an assessment, we will provide clear recommendations on how to mitigate against reported vulnerabilities and offer free remote retesting following remediation.

Types of Penetration Testing

Network Infrastructure Testing

Rootshell conducts in-depth assessments of your network environment to find and exploit security vulnerabilities. This helps determine whether assets like sensitive data can be accessed or compromised.

Cloud Penetration Testing

Cloud penetration testing evaluates the security posture of cloud-hosted environments and services, taking into account cloud-specific risks like misconfigured storage, access controls, and identity management.

Wireless Network Penetration Testing

Wireless penetration testing identifies vulnerabilities in Wi-Fi networks, such as weak encryption protocols or rogue access points, and assesses how attackers might exploit them.

Social Engineering Assessments

Human error remains one of the biggest cybersecurity threats. Rootshell’s social engineering testing includes targeted phishing simulations and other attack scenarios to evaluate how well your staff and systems respond to real-world social engineering attempts.

Mobile Application Security Testing

With mobile apps becoming a primary access point for customers, ensuring their security is vital. Rootshell performs thorough assessments of iOS and Android applications using up-to-date frameworks and tools, helping to identify vulnerabilities and improve the security of mobile platforms.

Web services penetration testing aims to identify security weaknesses within your web applications that could be leaving your organization open to cyber attack. The same methods as threat actors are safely utilised to confirm and demonstrate how a vulnerability could lead to a breach.

A penetration test simulates a real-world attack on your organization’s network, applications, and systems to identify any weaknesses. A pen test is conducted manually by skilled consultants, who use the same techniques as real-world hackers; you can think of it as ‘ethical hacking’. On the other hand, vulnerability scanning is carried out using automated tools and solely focuses on identifying vulnerabilities within software. Find out more about vulnerability and penetration testing services.

The duration depends on the size and complexity of the application, but most tests take between 3 to 10 working days from initial scoping to final reporting.

At a minimum, once a year or after major updates to the application. Regular testing is recommended as part of a continuous security strategy, especially if you deploy new features often.

No. A vulnerability scan is automated and provides a basic overview, while penetration testing involves an in-depth manual assessment and exploitation by ethical hackers to uncover complex, real-world risks.
