Web Application Penetration Testing
Identify The Hidden Risks in Your Web Applications
Professional web application security testing by certified ethical hackers.
Web applications are prime targets for cybercriminals because they're accessible from anywhere and often contain sensitive data. Our manual penetration testing goes beyond automated scanners to identify business logic flaws, authentication bypasses, and complex vulnerabilities that put your applications at risk. While automated scanners can find known vulnerabilities, they miss business logic flaws and complex attack chains that require human expertise to identify.
Our experienced penetration testers use the same techniques as real attackers, providing you with an authentic security assessment that reveals how your applications would fare against actual threats. With over a decade in business and thousands of clients served, we help organizations strengthen their web application security posture and discover critical issues before attackers exploit them.

Our Web Application Testing Process
-
Align on scope
We’ll ask you a few simple questions about what needs to be tested and align with you on your objectives and timeline.
-
Testing period
Your dedicated pentester will generally spend about one week searching for vulnerabilities and exposures.
-
Report & remediation
We’ll provide a detailed report on the issues we found and recommendations for remediation.
-
Retest and validate
After issues are resolved, we’ll retest to confirm that the issues are no longer present.
Frequently Asked Questions
How much does web application penetration testing cost?
Web application penetration testing starts at $4,975 and varies based on application complexity and scope. We provide fixed-price quotes with no hidden fees after our free scoping call.
Factors that affect pricing:
- Number of user roles and authentication levels
- Application size and complexity
- API endpoints and integrations
- Custom business logic requirements
Every quote includes comprehensive testing, detailed reporting, remediation support, and one round of retesting.
How is manual testing different from automated scanning?
Manual penetration testing provides deeper security analysis that automated tools cannot match:
- Business Logic Testing: Human testers understand application workflows and can identify logic flaws
- Complex Attack Chains: Manual testing can link multiple vulnerabilities for greater impact
- False Positive Elimination: Human validation ensures all findings are real security issues
- Custom Payloads: Testers create specific exploits tailored to your application
While automated scanners are useful for initial assessment, manual testing is essential for comprehensive security validation.
What applications and technologies do you test?
Our penetration testers have experience with a wide range of web technologies and frameworks:
- Custom web applications built with any framework
- E-commerce platforms and payment systems
- Customer portals and SaaS applications
- REST APIs, GraphQL, and web services
- Single-page applications (React, Angular, Vue.js)
- Content management systems and CMS platforms
We adapt our testing methodology to your specific technology stack and business requirements.
How long does web application penetration testing take?
Testing timeline depends on application complexity and scope:
- Simple Applications: 1-2 weeks for basic web apps with limited functionality
- Complex Applications: 3-4 weeks for enterprise apps with multiple user roles
- Large Applications: 4+ weeks for complex systems with extensive business logic
We provide specific timelines during the scoping phase and work with you to minimize disruption to your operations.
How do you you test applications that require authentication?
Of course. We regularly test authenticated web applications. Our testing can include:
- Multi-level user role testing (admin, user, guest)
- Session management and privilege escalation testing
- Role-based access control validation
- Single sign-on (SSO) and OAuth implementation testing
During scoping, we'll discuss the different user roles and access levels that should be tested, and you'll provide appropriate test accounts.
Do you provide ongoing support after testing?
Yes, we provide comprehensive support throughout the remediation process:
- Direct access to your penetration tester for questions
- Clarification on findings and remediation steps
- Guidance for development teams implementing fixes
- Included retesting to verify successful remediation
Our goal is not just to identify vulnerabilities, but to help you successfully secure your applications.
