Web Application Penetration Testing Service

We simulate real-world attacks to uncover the vulnerabilities that could lead to data breaches, unauthorised access, and operational disruption before attackers find them first.

Our consultants evaluate your authentication, session management, input validation, and overall security controls to ensure your applications can withstand cyber threats.

    Types of Web App Penetration Tests

    Known as “white box”, it assesses your web app’s security from the perspective of an attacker who has breached external defences or phished valid credentials to reveal the damage a successful cyber-attack could cause.

    What is Web App Penetration Testing?

    It's a proactive application security assessment that identifies and exploits vulnerabilities across web applications, APIs, and backend systems.

    By simulating real-world attacks, it uncovers weaknesses in authentication, session management, input validation, and security controls, giving you the confidence that your applications can withstand cyber threats.

      Why Should You Conduct Web App Pen Testing?

      Web applications expose a broad attack surface that requires comprehensive testing.

      • Prevent SQL injection, Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF).

      • Check the security of file upload functionalities to prevent malicious uploads and execution.

      • Ensure data is securely encrypted with strong ciphers and properly implemented.

      • Confirm that all application components are fully patched and up to date, reducing your exposure to threats.

      Methodology

      We ensure testing has both depth and breadth by aligning with recognised methodologies such as CREST, OSSTMM, OWASP, and NIST. 

      This ensures a structured, consistent approach grounded in best practice and real-world threat intelligence.

      We follow a clear seven-step process designed to deliver rigorous testing, meaningful insight, and practical remediation guidance at every stage.

      We listen to your needs and develop a tailored project strategy, producing a scope that meets your unique requirements.  

      We assess your target systems and design a testing approach based on: where your organisation is most vulnerable, the most effective and efficient attack techniques, and how to conduct the test while ensuring your organisation remains protected. 

      We scan and enumerate the defined targets to identify existing vulnerabilities. This includes listening for open ports, identifying running services, and developing an attack plan based on the scan results. 

      Our consultants assess how deeply they can access your systems using leading industry techniques, custom-built tools, and their first-hand experience. 

      If a consultant successfully exploits a vulnerability, they assess its severity. This involves determining which assets and networks can be accessed and how much information can be gathered. Your vulnerabilities are then ranked from low to critical in GuardNest.  

      Findings are published in a report on GuardNest, organised by category and type, with remediation advice for each exploit and vulnerability. On request, we also arrange debrief calls to review identified  risks in detail and discuss remediation. 

      Your GuardNest licence includes continuous external infrastructure scanning to minimise risk between tests. We also offer a remediation check service, and every engagement includes a full consultative approach to ensure ongoing support even after the project is complete.
