Web Application Penetration Testing
Uncovering Vulnerabilities in Your Web Application
Web applications are the face of your business in today’s digital world, but they also serve as prime targets for cybercriminals. At Xium Labs, our Web Application Penetration Testing service identifies vulnerabilities that could put your application and your sensitive data at risk. We help you fortify your web applications against attacks, ensuring a secure, seamless experience for your users
What is Web Application Penetration Testing?
Web Application Penetration Testing is a process of simulating cyberattacks against your web applications to identify vulnerabilities. These simulated attacks allow us to assess the security posture of your application and provide actionable insights for remediation, ensuring protection against potential breaches and compliance with industry standards
Who Needs Web Application Penetration Testing?
If your business runs a customer portal, an ecommerce store, a SaaS platform or any web application that handles personal or payment data, you are a target regardless of your size. Attackers scan the whole internet indiscriminately, and automated tools find weak applications within hours of deployment. Testing is most valuable before a major launch, after significant changes to authentication or payment flows, when a contract or framework requires independent assurance, and on a regular annual cycle in between.
What You Receive
Every engagement ends with evidence you can act on and share:
- A report with an executive summary written for decision makers and detailed technical findings for engineers.
- Severity ratings for every issue, with proof of exploitation and step-by-step reproduction.
- Clear remediation guidance your developers can implement without guesswork.
- A debrief call to walk through findings and answer questions.
- A free re-test within six weeks and an updated report confirming what was fixed.
Standards and Compliance
Our web application testing follows the OWASP Top 10 and the OWASP Web Security Testing Guide, so coverage is systematic rather than ad hoc. The resulting report supports Cyber Essentials Plus, ISO 27001 and SOC 2 requirements for independent security testing, PCI DSS obligations where cardholder data is involved, and the security-of-processing duties in Article 32 of UK GDPR. If a client or insurer has asked you for evidence of testing, this is the document that answers them.

Common Web Application Vulnerabilities
SQL Injection
Attackers manipulate database queries to access unauthorised data.
Cross-Site Scripting (XSS)
Malicious scripts are injected into web pages viewed by other users, potentially compromising user data.
Cross-Site Request Forgery (CSRF)
Attackers trick authenticated users into executing unwanted actions on a web application.
Insecure Direct Object References (IDOR)
Attackers gain access to unauthorised resources by manipulating user inputs.
Weak Authentication & Session Management
Poor login mechanisms, weak passwords, or improper session handling can lead to unauthorised access.
How Does Web App Penetration Testing Work?
At Xium Labs, we conduct thorough web application penetration tests by simulating real-world attacks to uncover potential weaknesses in your application. Our process involves the following steps:
- Initial Reconnaissance:We gather information about your web application’s structure and features.
- Threat Modelling:Identify potential threats based on the app’s use cases and data flow
- Vulnerability Scanning: Automated tools are used to detect common vulnerabilities.
- Manual Testing: Our certified testers perform manual tests to identify complex vulnerabilities that automated tools miss.
- Exploitation: We simulate potential attacks to understand the impact of the vulnerabilities.
- Reporting & Remediation: A detailed report is provided with vulnerabilities identified and steps for remediation.
