Find Every Flaw in Your Web Applications
Web applications are the primary attack surface for most organizations — and automated scanners catch less than half of the vulnerabilities that matter. Our web application penetration testing combines deep manual analysis with industry-leading tooling to uncover the critical flaws that scanners miss: business logic errors, complex authentication bypasses, race conditions, and chained attack paths that turn low-severity issues into full compromises.
What we test
Our testers systematically evaluate every attack vector relevant to this assessment type.
Authentication & Session Management
We thoroughly test your authentication mechanisms for password policy weaknesses, brute force susceptibility, credential stuffing resilience, multi-factor authentication bypass, and session fixation vulnerabilities. Our testers evaluate token generation entropy, session timeout enforcement, cookie security attributes, JWT implementation flaws, and OAuth/OIDC misconfigurations that could allow account takeover.
Injection Vulnerabilities
Beyond basic SQL injection, we test for blind and time-based SQLi, NoSQL injection against MongoDB and similar databases, LDAP injection, OS command injection, server-side template injection (SSTI), expression language injection, and XML external entity (XXE) attacks. Each injection vector is tested across all input points including headers, cookies, JSON bodies, and file uploads.
Business Logic Flaws
Automated scanners cannot find business logic vulnerabilities — they require human understanding of your application workflows. We test for price manipulation, coupon abuse, privilege escalation through workflow manipulation, race conditions in payment processing, IDOR vulnerabilities across multi-tenant boundaries, and state machine violations that let attackers skip required steps.
API Security Testing
Modern web applications are API-driven. We test REST, GraphQL, and gRPC endpoints for broken object-level authorization (BOLA), broken function-level authorization, mass assignment, excessive data exposure, rate limiting gaps, and improper input validation. GraphQL-specific testing covers introspection abuse, batch query attacks, and nested query depth exploitation.
Cross-Site Attacks (XSS/CSRF)
We identify stored, reflected, and DOM-based cross-site scripting vulnerabilities across your application, including contexts where standard payloads fail — JavaScript template literals, SVG handlers, CSS injection points, and dangerouslySetInnerHTML in React applications. CSRF testing evaluates token implementation, SameSite cookie configuration, and origin header validation.
Access Control & Authorization
We systematically test every endpoint and function for horizontal and vertical privilege escalation. This includes testing role-based access controls across all user types, evaluating multi-tenant isolation, checking for insecure direct object references, and verifying that server-side enforcement matches the access control model your application intends.
Our approach
A structured methodology that ensures thorough coverage and actionable results.
Scoping & Reconnaissance
We map your application architecture, identify all entry points, enumerate API endpoints, and understand user roles and business workflows. This phase includes technology fingerprinting, hidden endpoint discovery, JavaScript analysis for client-side routes and API calls, and documentation review to build a complete attack surface map.
Automated & Manual Assessment
We run calibrated automated scans using Burp Suite Pro alongside manual testing of every vulnerability class. Automated scanning provides broad coverage while our manual testing focuses on logic flaws, chained attacks, and context-specific vulnerabilities that tools cannot detect. Every automated finding is validated by hand to eliminate false positives.
Exploitation & Chaining
Confirmed vulnerabilities are exploited to demonstrate real business impact. We chain low-severity findings into high-impact attack paths — a reflected XSS combined with a CSRF bypass and an IDOR can equal full account takeover. This impact-driven approach helps your team prioritize remediation effectively.
Reporting & Retest
We deliver a detailed report with every finding documented — severity, CVSS score, reproduction steps, screenshots, HTTP request/response evidence, and tailored remediation guidance. After your team implements fixes, we perform a complimentary retest to verify that vulnerabilities are properly resolved and no regressions were introduced.
