Web Application Penetration Testing

Web Application Penetration Testing

Our web application penetration testing service identifies exploitable vulnerabilities in web applications and APIs through manual testing, attack simulation and expert validation. Find and fix the vulnerabilities attackers would exploit with proof, not just a scanner dump.

Web application penetration testing and API security assessment.

Overview

Web application penetration testing is an authorised security assessment that simulates real-world attacks against web applications and APIs to identify exploitable vulnerabilities before attackers can use them. IntelligenceX combines automated security testing with manual expert validation to identify issues such as broken access control, authentication flaws, injection vulnerabilities, business logic weaknesses and API security risks. Our testers validate exploitability, demonstrate potential business impact and provide prioritised, developer-ready remediation guidance to help organisations reduce the risk of data breaches and application compromise.

Methodology & Standards

OWASP WSTG v4.2, OWASP Top 10 (2021), OWASP ASVS and the OWASP API Security Top 10, framed by PTES and NIST SP 800-115. Burp Suite Pro plus manual verification removes false positives.

Frequently Asked Questions

No. Automated tools are only a starting point. Our testers manually validate every issue, remove false positives, and chain low-severity flaws into real attack paths that scanners cannot find. You get proof of exploitability, not a noisy tool dump.

We agree rules of engagement up front and prefer a staging mirror for destructive checks. Production testing is throttled and scheduled to avoid disruption, with a real-time contact channel throughout.

Yes. A remediation retest of all reported findings is included, and we issue an updated attestation letter confirming fixes were independently verified.

Typical assessments include authentication, authorization, session management, input validation, business logic, error handling, and API security controls.

Yes. Our web application penetration testing identifies vulnerabilities such as SQL injection, cross-site scripting (XSS), authentication flaws, business-logic vulnerabilities and API security issues, based on industry best practices and the OWASP Top 10.

Yes. We run comprehensive API security assessments covering authentication, authorization, rate limiting, business-logic flaws, data exposure and API abuse scenarios, aligned with the OWASP API Security Top 10.
