AI Security Testing

Vulnerability assessment services

AI is quickly becoming part of everyday business applications. Companies are using LLMs for customer support, internal assistants, document search, automation and decision-making. But once these systems are connected to company data, APIs and internal applications, they also create security risks that traditional penetration testing may not fully cover.

Nathan Labs Advisory provides AI Security Testing to help businesses understand how their AI applications could be attacked, manipulated or misused.

What We Test

Our testing looks at the complete AI application, not just the underlying model.

Prompt Injection Testing

We test whether specially crafted inputs can override system instructions, bypass restrictions, reveal hidden prompts or make the application behave in ways it was not designed to.

LLM Penetration Testing

Our consultants simulate realistic attacks against LLM-powered applications to identify weaknesses such as jailbreaks, information disclosure, insecure access controls and unintended model behaviour.

RAG Security Testing

For applications using Retrieval-Augmented Generation (RAG), we assess how information is retrieved from internal documents, databases, vector stores and knowledge bases. Testing includes unauthorized information retrieval, access-control weaknesses, retrieval manipulation and data poisoning scenarios.

Sensitive Data Leakage Testing

We check whether the AI can expose confidential information, customer data, internal documents, credentials, system prompts or other information that users should not be able to access.

AI Agent & Plugin Security

AI agents can interact with APIs, databases, applications and external tools. We test whether those capabilities can be abused to perform unauthorized actions or access information outside the user's intended permissions.

AI API Security Testing

We assess the APIs supporting the AI application, including authentication, authorization, input handling, rate limiting and other API security weaknesses.

Why AI Security Testing Matters

The risk with an AI application is not limited to getting an incorrect answer. A successful attack could allow someone to manipulate the application’s instructions, retrieve sensitive business information, bypass access restrictions or misuse systems connected to the AI.

These issues are often difficult to identify through automated vulnerability scanning alone because the outcome depends on how the model, application, data and integrations work together.

AI Security Testing provides a practical way to understand these risks before an application is widely deployed.

How Nathan Labs Advisory Can Help

Nathan Labs Advisory combines AI security testing, penetration testing, API security and application security to assess the complete AI environment.

Our consultants approach the application from an attacker’s perspective and test realistic misuse scenarios rather than relying only on automated scanning. We identify vulnerabilities, demonstrate their potential impact and provide practical recommendations for remediation.

Our testing can support organisations developing or deploying:

  • Generative AI applications
  • Enterprise AI assistants and copilots
  • Customer-facing AI chatbots
  • RAG-based applications
  • LLM-powered search platforms
  • AI agents and automated workflows
  • AI applications connected to internal business systems

Whether the AI solution is still under development or already in production, Nathan Labs
Advisory can help identify where it is exposed and what needs to be strengthened.
