Identify Application Vulnerabilities — Before Attackers Do

Whether web platforms, mobile apps, or traditional desktop software, almost every organization develops or relies on business-critical applications. These applications are among the most attractive targets for cyber attackers. Security flaws in the application itself or insecure interfaces can lead to serious cyber incidents.

Application Penetration Testing is designed to identify these vulnerabilities through structured, real-world security assessments. Our experts evaluate your applications using established methodologies such as the OWASP Web Security Testing Guide (WSTG) and help you understand, remediate, and sustainably reduce security risks.

We make your applications more resilient — through structured security assessments, actionable recommendations, and a solid foundation for continuous improvement.

Our Services at a Glance

Modern web applications are particularly exposed due to their complexity, numerous interfaces, and the processing of sensitive data.

Our assessments include, among other things:

  1. Testing for common vulnerabilities based on the OWASP Top 10 (e.g. SQL Injection, Cross-Site Scripting)
  2. Security assessment of APIs and web services based on the OWASP API Security Top 10
  3. Review of role-based access control and authorization concepts
  4. Static and dynamic source code analysis (depending on scope)
  5. Assessment of the underlying web server infrastructure
  6. Evaluation of connected backend systems, including databases

Mobile applications require particular attention due to their widespread use and the sensitive data they process.

Our methodology is based on the OWASP Mobile Security Testing Guide (MSTG) and includes:

  1. Testing for mobile-specific vulnerabilities based on the OWASP Mobile Top 10
  2. Assessment of APIs and authentication mechanisms
  3. Static and dynamic source code analysis
  4. Testing for platform-specific vulnerabilities on Android and iOS
  5. Evaluation of connected backend components such as servers and databases

Native desktop applications on Windows, macOS, and Linux often contain business-critical functionality and therefore represent attractive attack targets.

Our services include:

  1. Assessment of common vulnerabilities such as DLL hijacking, remote code execution (RCE), SQL Injection, and hard-coded credentials
  2. Reverse engineering and network communication analysis
  3. Source code reviews and privilege escalation testing
  4. Assessment of connected servers and backend systems

Applications powered by large language models (LLMs) introduce new attack vectors through manipulated prompts, insecure model outputs, and exposed API integrations.

Our assessments include, among other things:

  1. Testing for AI-specific vulnerabilities based on the OWASP Top 10 for LLM Applications (e.g. prompt injection and data leakage)
  2. Assessments following the OWASP AI Security Testing Guide
  3. Security evaluation of connected APIs, plugins, and retrieval components
  4. Technical assessment of LLM integration within frontend and backend applications
  5. Review of authentication and authorization controls surrounding AI components
  6. Validation of model and infrastructure configurations

Our findings are clearly documented, prioritized, and reviewed together with your team. If required, we also support you in establishing secure software development practices and effective patch management processes.
