Web application penetration testing.

We test single-page applications, multi-tenant SaaS platforms, and enterprise web portals for authentication bypasses, broken access controls, injection vulnerabilities, and business workflow flaws.

Web Application Penetration Testing Architecture

What is in scope

Key technical areas and vulnerability classes evaluated during the assessment.

Authentication and session management

Testing login flows, multi-factor authentication, password reset workflows, OAuth 2.0 and SAML integrations, session fixation, and token expiration handling.

Authorization and multi-tenant isolation

Testing horizontal privilege escalation (IDOR across user or tenant records) and vertical privilege escalation (accessing administrative functions from standard accounts).

Injection and server-side flaws

Testing for SQL injection, NoSQL injection, OS command injection, Server-Side Request Forgery (SSRF), XML/XXE parsing flaws, and insecure deserialization.

Client-side and DOM security

Testing for stored, reflected, and DOM-based Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), CORS misconfigurations, and clickjacking.

Business logic and race conditions

Testing multi-step checkout, payment, quota, and approval workflows for state manipulation and parallel request race conditions.

File uploads and parser security

Testing document, image, and archive upload handlers for unrestricted file execution, path traversal, and cloud storage exposure.

Testing methodology

Our step-by-step engineering workflow from reconnaissance to verified proof of concept.

1. Application mapping and role matrix setup

We map every route, input parameter, and user role across your web application to build a complete authorization test matrix.

2. Automated baseline and configuration audit

We evaluate TLS settings, HTTP security headers (CSP, HSTS, X-Frame-Options), cookie flags, and framework-level exposures.

3. Manual exploitation and workflow testing

Our engineers manually test each function using intercepting proxies and custom scripts, chaining findings to demonstrate real business impact.

4. Remediation verification

Once your developers deploy fixes, we re-run our test cases to confirm the vulnerabilities are resolved without introducing regressions.

Deliverables and retesting

What your engineering and compliance teams receive at the conclusion of testing.

Detailed technical report

Contains CVSS severity ratings, affected URLs and parameters, full HTTP request and response captures, and clear reproduction steps.

Developer remediation guidance

Provides framework-specific code examples and architectural recommendations to fix the root cause of each finding.

Verification and attestation letter

Includes a post-remediation retest report and formal VAPT attestation letter suitable for customer security reviews and compliance audits.
