Web Application Penetration Testing

Web application penetration testing is a deep-dive security assessment of your web-based applications — including the APIs, authentication systems, session management, and business logic that power them. While automated scanners can identify known vulnerability patterns, experienced testers are required to discover business logic flaws, authentication bypasses, and chained vulnerabilities that require contextual understanding of your specific application. Our assessments align with the OWASP Testing Guide and OWASP Web Security Testing Guide (WSTG), ensuring comprehensive coverage of the OWASP Top 10 and beyond.

Web applications are the primary attack vector in the majority of data breaches. SQL injection, cross-site scripting, broken authentication, and insecure direct object references have been responsible for some of the most damaging breaches in history. More sophisticated are the business logic vulnerabilities unique to each application — price manipulation, unauthorized privilege escalation, or workflow bypasses that no scanner can detect because they require understanding how the application is supposed to behave. For e-commerce platforms, financial applications, and SaaS products, a single exploited flaw can expose millions of customer records or enable fraudulent transactions.

BugFoe web application testers use a black-box, grey-box, or white-box approach depending on your security objectives. We test both authenticated and unauthenticated attack paths, covering all user roles from anonymous visitor to administrator. Our team intercepts and analyzes all application traffic, tests every input field and API endpoint, and specifically hunts for business logic vulnerabilities that automated tools miss. Findings are reported with CVSS scores, exploit demonstrations, and developer-friendly remediation guidance that references the specific file, function, or configuration that needs to change. Free retesting is offered within 90 days for all critical and high findings.
