Application & Web Application Pentest: Security at the Application Level
Traditional network pentests are not sufficient when your business logic resides in web applications and APIs. Our application pentest specifically examines the security of your applications – from authentication and authorization to business logic.
What is an application pentest?
- Web applications and single-page apps (SPAs)
- REST and GraphQL APIs
- Authentication and authorization mechanisms
- Business logic and workflows
- File uploads, session management and input validation
Application pentest procedure
Application architecture analysis
- Mapping of all endpoints, roles and data flows.
- Identification of technologies and frameworks in use.
Automated and manual vulnerability analysis
- Testing for OWASP Top 10 (Injection, XSS, SSRF, IDOR and more).
- Manual analysis of authentication, authorization and business logic.
Documentation and recommendations
- Detailed report with reproducible findings and risk assessment.
- Prioritized remediation measures – including developer-friendly recommendations.
Benefits of an application pentest
Business logic protection
Errors in application logic are often missed by automated scanners – our experts catch them.
OWASP-compliant testing
Systematic coverage of the OWASP Top 10 and beyond, tailored to your application.
API security
REST and GraphQL APIs are specifically tested for Broken Access Control, Mass Assignment and Injection.
Developer-friendly results
Findings are documented with concrete code examples and reproduction steps – directly actionable for your dev team.
Compliance evidence
Meet requirements from ISO 27001, PCI DSS and industry-specific standards with a thorough test report.
Frequently Asked Questions
01 What distinguishes an application pentest from a classic pentest?
A classic (external/internal) pentest focuses on the network and infrastructure level. The application pentest goes deeper and examines the logic, implementation and configuration of your software – things like authentication, role management, input validation and API security.
02 What information do you need in advance?
Ideally, access to a test or staging environment, API documentation and test accounts with different roles. Depending on the depth of testing, source code can also be helpful (white-box approach).
03 How long does an application pentest take?
Depending on the scope and complexity of the application, typically 1–3 weeks. A small API can be tested in a few days, while a complex web platform requires correspondingly more time.
04 Do you also test during development?
Yes, we also offer accompanying security tests during the development phase. This allows vulnerabilities to be fixed early, before they reach production.
05 Will I receive support in fixing the findings?
Absolutely. Our team is available for questions and can also provide direct support in implementing the recommended measures if needed.
