Web Application Penetration Testing

Your web applications are among your most exposed assets. Our CREST Pathway certified consultants go beyond automated scanning to find the vulnerabilities that matter — from injection flaws to broken access controls.

Understanding the Risk

What is Web Application Penetration Testing?

Web applications expose your data beyond the network perimeter. Customer portals, e-commerce platforms, SaaS dashboards, and internal tools all present attack surfaces that are directly accessible from the internet. A single vulnerability can lead to data theft, account takeover, or full system compromise.

We test like a real attacker, not a scanner. Our consultants manually probe your application’s authentication, authorisation, input handling, session management, and business logic — areas where automated tools consistently fall short.

You get findings you can act on. Every vulnerability is demonstrated with proof of exploitation, rated by business impact, and accompanied by clear remediation guidance tailored to your technology stack.

The Case for Testing

Why Your Web Applications Need Penetration Testing

01

Your apps are internet-facing

Web applications are accessible to anyone with a browser. They are the most common entry point for external attackers targeting your organisation's data.

02

Scanners miss business logic flaws

Automated tools catch common issues but miss authentication bypasses, privilege escalation, and workflow manipulation that require human reasoning to discover.

03

New features introduce new risks

Every release, feature update, or third-party integration can introduce vulnerabilities. Regular testing ensures new code doesn't create new attack paths.

04

Compliance demands it

PCI DSS, ISO 27001, and Cyber Essentials Plus all require or recommend application-level penetration testing, particularly for systems handling sensitive data.

05

Customer trust depends on it

A breach of your web application directly impacts your users. Proactive testing demonstrates your commitment to protecting their data.

How We Work

Our Testing Approach

OWASP-Based Assessment

We test against the OWASP Top 10 and beyond — covering injection, broken authentication, sensitive data exposure, security misconfiguration, XSS, CSRF, and more.

Authentication and Authorisation Testing

We probe login mechanisms, password policies, session handling, multi-factor authentication, and role-based access controls for bypasses and weaknesses.

Business Logic Testing

We assess application workflows for flaws that allow users to manipulate pricing, skip steps, escalate privileges, or access data belonging to other users.

API and Integration Testing

We examine the APIs powering your web application for insecure endpoints, missing authentication, excessive data exposure, and injection vulnerabilities.
