Web Application Penetration Testing

Deep-Dive Security Testing for Modern Web Applications

Your web applications are your primary attack surface. Our web application penetration testing goes far beyond running automated scanners against your URLs. We perform deep manual testing that examines every input field, every API endpoint, every authentication flow, and every business logic path in your application. Our testers think like attackers and find vulnerabilities that DAST and SAST tools fundamentally cannot detect.

Our Methodology

We follow a rigorous, structured approach to ensure comprehensive coverage and actionable results.

1

Application mapping and discovery to understand all endpoints, parameters, and user roles

2

Authentication and session management testing including SSO, OAuth, JWT, and MFA bypass attempts

3

Authorization testing across all user roles to identify privilege escalation and IDOR vulnerabilities

4

Input validation testing for XSS, SQL injection, command injection, and template injection across every parameter

5

Business logic testing to identify flaws in payment flows, discount systems, and workflow bypasses

6

Client-side security review including JavaScript analysis, DOM manipulation, and storage security

Real-World Attack Scenarios

These are the types of attacks we simulate to test your defenses against real threat actors.

Authentication Bypass & Account Takeover

We test every authentication mechanism in your application, from login forms to password resets to OAuth integrations. Common findings include JWT misconfiguration allowing token forgery, password reset token prediction, race conditions in login flows, and session fixation vulnerabilities that enable complete account takeover.

SQL Injection & Data Exfiltration

Our testers manually probe every parameter for SQL injection, including blind and out-of-band variants that automated tools frequently miss. We demonstrate full data exfiltration paths, showing how an attacker could extract your entire database through a single injection point using techniques like UNION-based, error-based, and time-based attacks.

Cross-Site Scripting (XSS) Attack Chains

We go beyond finding basic reflected XSS. Our team identifies stored XSS, DOM-based XSS, and mutation XSS variants, then demonstrates real impact by chaining them with other vulnerabilities to steal admin sessions, create backdoor admin accounts, or exfiltrate sensitive user data at scale.

Server-Side Request Forgery (SSRF) to Cloud Compromise

Modern applications frequently integrate with cloud services, creating SSRF opportunities. We test for SSRF in file upload features, URL parsers, webhook systems, and PDF generators, then demonstrate how SSRF can be escalated to access cloud metadata services, internal APIs, and sensitive infrastructure.

Tools & Technologies

Frequently Asked Questions

Do you test single-page applications (SPAs) and modern JavaScript frameworks?

Absolutely. We have deep expertise testing React, Angular, Vue, Next.js, and other modern SPA frameworks. Our testers understand client-side routing, state management, API communication patterns, and framework-specific vulnerabilities. We also test the underlying REST and GraphQL APIs that power these applications.

How is your testing different from running an automated DAST scanner?

Automated scanners find about 30-40% of vulnerabilities in a typical web application. They fundamentally cannot test business logic, complex authentication flows, multi-step workflows, or chained vulnerabilities. Our manual testing finds the other 60-70% that actually matters most, including authorization flaws, race conditions, and business logic bypass.

Can you test applications behind authentication?

Yes. We test both unauthenticated and authenticated attack surfaces. You provide us with test accounts for each user role, and we thoroughly test authorization controls, privilege escalation paths, and session management across all roles. We also test the authentication mechanisms themselves.

What reporting format do you provide?

We provide a comprehensive report that includes an executive summary for leadership, detailed technical findings with CVSS scores, proof-of-concept exploit demonstrations, and step-by-step remediation guidance. Reports are delivered in PDF format with an optional machine-readable JSON format for integration with your issue tracking systems.
