Web Application Testing
Your web apps, tested beyond automated scans.
Following OWASP methodologies, we probe your web applications for injection flaws, authentication bypasses, business logic vulnerabilities, and data exposure risks.
Overview
Web application penetration testing goes far beyond automated scanning. Our testers manually analyze your application's functionality, business logic, and data flows to identify vulnerabilities that automated tools miss. We test authentication, authorization, session management, input validation, and application-specific functionality using the OWASP Testing Guide as our foundation.
What We Test
Our web application testing engagements cover these key areas:
Authentication & Sessions
Login mechanisms, password policies, session management, and multi-factor authentication implementation tested for bypass opportunities.
Authorization Controls
Role-based access controls, privilege escalation, and horizontal/vertical access control weaknesses evaluated.
Injection Vulnerabilities
SQL injection, command injection, LDAP injection, and other injection attack vectors tested across all input points.
Business Logic Flaws
Application workflows analyzed for logical vulnerabilities that could allow fraud, data manipulation, or process bypass.
Client-Side Security
JavaScript analysis, DOM-based vulnerabilities, and client-side storage examined for security weaknesses.
Data Protection
Encryption, data exposure in transit and at rest, and sensitive data handling evaluated.
Our Approach
Our web application testing combines automated scanning with extensive manual testing, focusing on vulnerabilities that require human understanding of application context and business logic.
Application Mapping
We map the application's functionality, user roles, data flows, and technology stack to understand the attack surface.
Automated Scanning
Vulnerability scanners identify common issues, while we manually verify and expand on automated findings.
Manual Testing
Each functional area is tested manually for OWASP Top 10 vulnerabilities and business logic flaws.
Exploitation
Identified vulnerabilities are exploited to demonstrate real impact and data exposure potential.
Common Findings
These are issues we frequently discover during web application testing engagements:
SQL Injection
CriticalInput fields vulnerable to SQL injection, potentially allowing data theft, modification, or complete database compromise.
Broken Access Control
HighUsers able to access resources or functionality outside their authorized permissions through IDOR or privilege escalation.
Cross-Site Scripting (XSS)
MediumUser input reflected or stored without sanitization, enabling session theft or malicious content injection.
Insecure Direct Object References
HighPredictable identifiers allowing access to other users' data by manipulating URL parameters or API calls.
Weak Session Management
HighSession tokens that are predictable, don't expire properly, or are transmitted insecurely.
Sensitive Data Exposure
HighPII, credentials, or other sensitive information exposed through API responses, error messages, or inadequate encryption.
Common Questions
Do you test in production or do we need a staging environment?
We can test either. Production testing reveals real-world vulnerabilities but carries some risk. Staging environments are safer but may miss production-specific configurations. We'll recommend an approach based on your application and risk tolerance.
Do you need credentials or source code access?
For thorough testing, we recommend authenticated testing with accounts at each user role level. Source code access (gray-box testing) helps identify deeper vulnerabilities. We can also test black-box with no credentials if you want to simulate an external attacker.
How long does web application testing take?
Typically 1-3 weeks depending on application complexity. Simple applications with few features might take a week; large enterprise applications with many user roles could take 3+ weeks.
Other Application Testing Options
Mobile Application Testing
Security assessment of iOS and Android applications covering client-side vulnerabilities, backend API security, data storage, and platform-specific attack vectors.
API Security Testing
Comprehensive security assessment of REST, GraphQL, and SOAP APIs covering authentication, authorization, injection vulnerabilities, and business logic flaws.
