Web Application Penetration Testing

Manual-first, exploit-validated testing of your web applications and the APIs behind them, against OWASP WSTG, ASVS and the API Top 10. Scanner output is not a finding.

What it is

Three shapes, scoped to what you actually run: web application only, API only, or both. The right shape gets proposed at scoping; the call is yours.

Depth and order are set by what day one surfaces. Every confirmed critical is reported the moment it is validated, so you patch while testing continues. For the platform underneath the application, see cloud penetration testing.

Method

• Authenticated and unauthenticated testing across every defined role
• Business-logic abuse derived from your real product flows
• Authentication, session and access control against OWASP ASVS 5.0, Level 2
• Server-side injection: SQLi, SSRF, command injection, deserialisation
• Client-side: XSS, CSRF, prototype pollution, postMessage handling
• API: OWASP API Top 10 — BOLA, BFLA, mass assignment
• GraphQL: introspection abuse, depth and complexity attacks, batching
• Chained exploitation to demonstrate real impact, where in scope

What you get

• Executive summary in plain language — no CVSS, no jargon
• Technical findings with CVSS v3.1 vector, evidence, repro steps and fix guidance
• Findings as CSV or JSON for your tracker, on request
• Walkthrough call with your engineers after delivery
• Retest by agreement
