Web Application Penetration Testing Services

Gain peace of mind with our web application pentesting service. Our team of UK-based certified ethical hackers will simulate real-world attacks to identify and exploit vulnerabilities in your web applications, APIs, and mobile apps.

Authenticated and unauthenticated testing of your web applications to identify vulnerabilities such as SQL injection, cross-site scripting, and more.

What Our Web App Testing Includes

Our web application penetration testing service a thorough assessment of the security of your web applications, websites, and APIs. This includes identifying security vulnerabilities and exploiting them to demonstrate the potential impact of a successful attack.

We go above and beyond the OWASP Top 10 to ensure that your applications are secure against a wide range of threats.

Authenticated & Unauthenticated Testing

Alongside unauthenticated testing we provide Authenticated testing, delving deeper into your web applications to identify authorisation and access control issues, as well as other vulnerabilities that may not be visible during unauthenticated testing.

This includes testing user roles, access control, permissions, and session management.

OWASP Standards

Our testing methodology is aligned with the OWASP Top 10, ensuring that we cover the most critical web application vulnerabilities.

This includes broken access control, SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and more.

API Testing

We include API penetration testing as part of our web application assessments.

This ensures that your web application’s API endpoints are secure against common vulnerabilities such as parameter manipulation, broken object level authorisation, excessive data exposure, and more.

Manually Led Testing

Our web application testing methodology is 100% manually led, and combines both manual and automated testing techniques.

This means we perform manual testing to uncover complex vulnerabilities and logic flaws that automated tools may miss, while also leveraging automated tools to ensure thorough coverage of your applications.

Business Logic Flaws

In addition to technical vulnerabilities, we also assess your web applications for business logic flaws.

These are vulnerabilities that arise from the way your application is designed and how it handles user interactions, which can lead to unintended consequences or security issues.

Detailed Reporting

We provide detailed executive and technical reports that include a summary of findings, technical details, and actionable recommendations for remediation.

Our reports are tailored to both technical and non-technical stakeholders, ensuring clarity and understanding.
