Web Application Penetration Testing Services
Bugstrix performs manual, OWASP-aligned penetration testing to identify exploitable vulnerabilities in web applications, APIs, authentication, authorization, and business logic.
Web Application Security Testing & Ethical Hacking
Web applications can expose risks in authentication, authorization, input handling, session management, and business logic. Bugstrix performs manual, OWASP-aligned penetration testing to identify exploitable weaknesses such as SQL injection, XSS, broken access control, and authentication flaws. You receive a prioritized report with evidence and remediation guidance to reduce risk and support relevant compliance requirements.
Start AssessmentWeb Application Attack Vectors & Vulnerabilities We Test
SQL Injection Attacks
Attackers manipulate database queries to illegally access, modify, or exfiltrate sensitive business data.
Cross-Site Scripting (XSS)
Malicious scripts injected into trusted web pages to hijack user sessions and steal credentials.
Broken Authentication Flaws
Weak login mechanisms exploited to hijack accounts and gain unauthorized access to your systems.
Security Misconfigurations
Poorly configured servers, HTTP headers, or cloud settings that expose your application to attackers.
Insecure Direct Object Reference
Unauthorized access to sensitive files or databases by manipulating exposed object references.
Sensitive Data Exposure
Unencrypted or poorly protected data intercepted, stolen, or leaked by attackers during transmission.
Why Web App Pen Testing Matters
Web application penetration testing helps identify and validate exploitable weaknesses in authentication, authorization, APIs, sessions, input handling, and business logic before they create greater security risk.
For in-scope applications, PCI DSS requires penetration testing at least annually and after significant changes. Web application testing can also support HIPAA risk analysis and ISO 27001 vulnerability-management programs.
Proactive web application penetration testing helps reduce financial, operational, and reputational risk while demonstrating a structured approach to protecting customer data and business systems.

Web App Penetration Approach
Reconnaissance & Intelligence Gathering
We collect intelligence on the application architecture, endpoints, APIs, and technology stack to map the agreed attack surface and identify potential entry points.
Threat Modeling & Attack Planning
We identify and prioritize potential attack vectors, entry points, and higher-risk areas based on architecture, business impact, and relevant threat intelligence.
Vulnerability Discovery & DAST Testing
Manual and automated dynamic application security testing identifies exploitable flaws, misconfigurations, and weaknesses across the tested application scope.
Exploitation & Proof of Concept
Where authorized, our testers safely validate selected vulnerabilities to assess real-world impact and exploitability, with proof-of-concept evidence where appropriate.
Post-Exploitation & Lateral Movement
Where authorized, we assess potential access to sensitive data, privilege escalation, and lateral movement within the agreed testing scope.
Reporting, Remediation & Re-Testing
Detailed penetration testing reports include risk-rated findings, actionable remediation guidance, and free re-testing until reported vulnerabilities are verified as resolved.
