Web Application Penetration Testing

We thoroughly test for all OWASP Top 10 vulnerabilities including injection flaws, broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfigurations, cross-site scripting, insecure deserialization, using components with known vulnerabilities, and insufficient logging. Our testing methodology ensures comprehensive coverage of these critical security issues that affect the vast majority of web applications.

We evaluate the strength of your authentication mechanisms, testing for weak password policies, session management flaws, multi-factor authentication bypasses, and privilege escalation vulnerabilities. Our testing helps ensure that only authorized users can access sensitive functionality and data, protecting your application from unauthorized access and account takeover attacks.

Beyond technical vulnerabilities, we examine how your application handles business processes. We test for logic flaws that could allow users to manipulate pricing, bypass payment systems, abuse discount codes, or exploit workflow processes in unintended ways. These vulnerabilities often can't be detected by automated tools and require expert manual testing to uncover.

We test how your application handles various types of user input, looking for injection vulnerabilities (SQL, NoSQL, command injection), cross-site scripting, file upload vulnerabilities, and data validation issues. Proper input validation is crucial for preventing attackers from manipulating your application's behavior or accessing sensitive data through malicious input.

We analyze how your application manages user sessions, testing for session fixation, predictable session tokens, insecure cookie configurations, and cross-site request forgery vulnerabilities. Proper session management is critical for maintaining user security and preventing session hijacking attacks that could compromise user accounts.

Even secure code can be vulnerable through misconfiguration. We review your application's security headers, CORS policies, TLS configuration, error handling, and server settings. We check for information disclosure through verbose error messages, unnecessary services, default credentials, and other configuration issues that could provide attackers with valuable information or access.
