Web Application Penetration Testing Services
Your web applications are critical business assets — and among the most targeted attack surfaces in any organisation. GoAgile Technologies delivers comprehensive web application penetration testing that goes beyond automated scanning, simulating real-world attack scenarios to uncover the vulnerabilities that matter before malicious actors do.
Intelligence-Led Testing Methodology
Our approach integrates advanced tooling with deep human expertise to deliver enterprise-grade security assessments. Every engagement follows a structured, repeatable process tailored specifically to web application environments.
Scope & Recon
Define the application boundary, identify the technology stack, and map the full attack surface
What you receive:
Application profile, technology stack, attack surface map
Vulnerability Analysis
Systematically identify common and complex vulnerabilities, including the OWASP Top 10 and beyond
Exploitation
Safely attempt to exploit identified vulnerabilities to confirm real-world impact and business risk
Reporting & Guidance
Deliver detailed findings, risk ratings, and prioritised remediation recommendations
Our Comprehensive Testing Portfolio
OWASP Top 10 Vulnerabilities Assessment
We systematically test for the most critical web application security risks as outlined by the OWASP Top 10, including Injection, Broken Authentication, Sensitive Data Exposure, XML External Entities (XXE), Broken Access Control, Security Misconfigurations, Cross-Site Scripting (XSS), Insecure Deserialization, and Using Components with Known Vulnerabilities.
API Security Testing
With the increasing reliance on APIs, securing these interfaces is paramount. Our testing covers REST, SOAP, and GraphQL APIs, focusing on vulnerabilities such as broken object level authorization, excessive data exposure, broken function level authorization, and mass assignment, ensuring secure data exchange and functionality.
Client-Side Security Analysis
Client-side vulnerabilities can expose users to risks like phishing and data theft. We assess the security of client-side scripts, local storage, and browser-side controls to prevent attacks such as DOM-based XSS, clickjacking, and insecure client-side data storage.
Business Logic Flaw Detection
Beyond technical vulnerabilities, we delve into the application’s unique business logic to uncover flaws that could be exploited for unauthorized actions, fraud, or data manipulation. This includes testing for issues like improper workflow enforcement, parameter tampering, and race conditions.
Tailored testing approaches
| Approach | What it simulates | Best suited for |
|---|---|---|
| Black Box | An external attacker with zero knowledge of the application's internals | External-facing apps, pre-launch assessments |
| Grey Box | A compromised insider or threat actor with partial access (credentials, architectural overview) | Post-authentication flows, privilege escalation testing |
| White Box | Full access to source code, architecture diagrams, and environment details | Deep-dive code review, CI/CD pipeline integration, maximum coverage |
Why GoAgile for web application pentesting?
Our web application security practice is built around one principle: findings that drive real change. Every engagement delivers not just a vulnerability list, but the context, business impact assessment, and step-by-step remediation guidance your development and security teams need to act.
We bring expertise across modern web architectures — monolithic, microservices, serverless, and API-first — and combine that with a developer-aware approach that supports secure development culture, not just point-in-time compliance.
Human-led, not tool-dependent
Automated scanners find the obvious. Our consultants find the rest — business logic flaws, chained vulnerabilities, and application-specific weaknesses that no scanner is built to detect.
Reporting built for two audiences
Every report includes a management-ready executive summary and a developer-ready technical breakdown — so the right people understand the risk and know exactly what to fix first.
Retest included
We don’t close an engagement at the report. Once your team has addressed the findings, we retest to verify the fixes hold — giving you documented evidence of remediation.
Secure your web applications before someone else tests them for you.
