Web Application Penetration Testing
Deep, OWASP-aligned web app testing.
Manual-led testing of your web applications against the OWASP Web Security Testing Guide and Top 10, covering authentication, authorization, injection, and the business-logic flaws automated scanners miss.
What we test
Where we focus
Authentication and session management
Authorization, access control, and IDOR
Business-logic and workflow abuse
Injection (SQL, command, template, and more)
Cross-site scripting and client-side flaws
Server-side request forgery (SSRF)
Cross-site request forgery (CSRF)
File upload and handling
Configuration, hardening, and secrets
This is part of our Vulnerability Assessment & Penetration Testing service. Retest validation is included at no added cost.
Why web apps need manual testing
Scanners miss what matters most
Web applications are where most organizations meet their customers, and where most attackers look first. Automated scanners are good at finding shallow, well-known issues, but the flaws that cause real breaches usually live in authentication, access control, and business logic, where only a human tester who understands your workflows can find them.
Our testing is manual-led and aligned to the OWASP Web Security Testing Guide (WSTG) and the OWASP Top 10. We test the application the way an attacker would, chaining lower-risk issues into full attack paths, and we validate every finding by hand so you get proof of impact, not scanner noise. Every engagement includes retest validation at no added cost.
Grounded in the OWASP Testing Guide
The areas we test in depth
We work through the OWASP Web Security Testing Guide and Top 10, then go beyond the checklist to test how your specific application behaves under abuse.
Business logic and workflow abuse
Flaws in how the application is meant to work: bypassing multi-step workflows, abusing pricing, discount, and quantity logic, replaying or tampering with transactions, skipping approval or verification steps, and defeating rate or usage limits. These have no signature and are invisible to scanners, so we learn what your application is supposed to enforce and then try to break those assumptions.
Authentication and session management
Weak or guessable credentials, flawed multi-factor and password-reset flows, session fixation, weak token generation, and logout and timeout handling that leaves sessions alive.
Authorization and access control
Insecure direct object references (IDOR), horizontal and vertical privilege escalation, forced browsing to hidden functions, and multi-tenant isolation gaps that expose other customers' data.
Injection
SQL, NoSQL, OS command, LDAP, XML, ORM, and server-side template injection, tested by hand to confirm real impact rather than reflected error strings.
Cross-site scripting and client-side flaws
Reflected, stored, and DOM-based XSS, plus DOM clobbering, prototype pollution, and unsafe use of client-side frameworks and third-party scripts.
Server-side request forgery and file handling
SSRF into internal services and cloud metadata, along with unrestricted file upload, path traversal, and unsafe file parsing and storage.
Cross-site request forgery and state changes
Missing or bypassable anti-CSRF protection on state-changing actions, weak same-site and origin controls, and unsafe cross-origin resource sharing (CORS).
Configuration, secrets, and data protection
Security headers, TLS and cookie flags, verbose errors and information disclosure, exposed admin and debug endpoints, hard-coded secrets, and weak or missing encryption in transit and at rest.
