What is Web Application Pentesting?

Web applications remain the primary attack vector for data breaches. Our web application penetration testing delivers a comprehensive, manual-first assessment of your web application against the OWASP Top 10 and beyond - identifying the vulnerabilities that automated scanners consistently miss. We test for the full spectrum of web application vulnerabilities: SQL Injection (SQLi), Cross-Site Scripting (XSS) including stored, reflected, and DOM-based variants, Cross-Site Request Forgery (CSRF), Insecure Direct Object References (IDOR), Server-Side Request Forgery (SSRF), XML External Entity (XXE) injection, and authentication/session management flaws. We go deeper into business logic testing, privilege escalation, and access control bypass that require human expertise to discover. Our methodology covers both authenticated and unauthenticated testing perspectives. We test every user role in your application - from anonymous visitors to administrators - to identify horizontal and vertical privilege escalation paths. Session management testing includes token entropy analysis, cookie security flags, session fixation, and concurrent session handling. We specialize in modern web frameworks including React, Angular, Vue.js, and Next.js. We understand how client-side rendering, single-page application (SPA) routing, state management, and API integration create unique attack surfaces. We also review security headers (CSP, HSTS, X-Frame-Options), CORS configuration, and third-party library vulnerabilities. Every engagement includes compliance mapping to the frameworks that matter to your business - SOC 2, PCI DSS, HIPAA, or ISO 27001. Critical vulnerabilities are reported immediately during testing, and we include one round of free retesting after your team implements fixes.
