LLM Security Testing
Classic penetration tests quickly reach their limits with AI-based applications. With our white-box approach for LLM security, we reliably identify vulnerabilities – from architecture to operation.
Large Language Models and AI components do not function deterministically – the same input can produce different results. This makes stochastic penetration tests, which are based on repeated trial and error, of limited significance.
An effective approach to the security of AI applications, therefore, requires more: a systematic white-box analysis based on detailed information about architecture and implementation. This is the only way to comprehensively identify and assess risks in the model, integration, APIs, infrastructure, and cloud environment.
Our Services
We offer you a targeted security audit of your AI-based applications – either comprehensively or focused on selected system components. We are guided by current standards and frameworks:
- OWASP LLM Top 10: Classification and evaluation of the most common risks in LLM applications.
- Mitre ATLAS: Structured threat analysis for the secure use of AI.
Approach
Our analyses combine classic methods of application security with AI-specific tests. We use static, dynamic, and audit-based methods.
- Kick-off & Scoping: Joint definition of the goals and relevant system components.
- Architecture Review: Analysis of the overall architecture and data flows with a focus on security gaps.
- Whitebox Analysis: Investigation of implementation, interfaces, and integrations.
- Static & dynamic tests: Use of code analyses, audits, and targeted penetration tests.
- Result preparation: Detailed reports with prioritized recommendations for action for technology and management.
Checkpoints
We examine your AI applications along the entire value chain, focusing on:
- Vulnerabilities in LLM and AI components
- Risks according to OWASP LLM Top 10 and Mitre ATLAS
- Security of application and cloud environments
- Securing APIs, data flows, and integrations
- Lifecycle and architecture analysis (design, deployment, operation)
- Effectiveness of existing protection and governance measures
Your Benefit
Our analysis approach provides clarity about the actual security of your AI-based applications – beyond the limitations of classic penetration tests.
We combine white-box methods with established standards and contribute our expertise from Application Security and Cloud Security. This allows us to not only uncover LLM-specific risks, but also evaluate the entire system architecture and lifecycle. The result: a well-founded security profile with clear, practical recommendations.

mgm DeepDive
Conventional penetration tests are not sufficient for AI-based applications. While they reliably detect vulnerabilities in classic systems, they quickly reach their limits with LLMs and generative AI due to their non-deterministic behavior.
| Classic penetration tests | LLM analysis (white-box approach) | |
|---|---|---|
| Methodology | Stochastic trial and error of possible inputs (“black box testing”) | Systematic white-box analysis with architecture and implementation knowledge |
| Suitability for LLMs | Limited, as AI outputs are variable and not reproducible | Highly suitable, as vulnerabilities in the model, interfaces, and integrations are specifically examined |
| Objective | Detection of classic vulnerabilities (e.g., Injection, XSS, SQLi) | Assessment of LLM-specific risks such as Prompt Injection, Data Leakage, Jailbreaks |
| Transparency | Limited insight, focus on Input/Output | Deep insight into architecture, data flows, code, and deployment |
| Standards | OWASP Top 10, NIST, ISO | OWASP LLM Top 10, Mitre ATLAS, supplemented by Application & Cloud Security |
| Result | List of classic vulnerabilities with fix recommendations | Holistic security profile including AI-specific threats and lifecycle analysis |
