AI Systems Penetration Testing

Secure your LLM apps, agents, and AI features.

We test AI-enabled applications, model endpoints, RAG pipelines, and autonomous agents for the failure modes unique to AI, aligned to OWASP and MITRE ATLAS guidance for AI security, alongside the traditional application and API weaknesses they still inherit.

What we test

Where we focus

Prompt injection (direct and indirect)

Insecure output handling and downstream impact

Sensitive data and training-data leakage

Model and RAG access control and tenant isolation

Tool / function-call and agent abuse

Supply-chain and model-integrity risks

This is part of our Vulnerability Assessment & Penetration Testing service. Retest validation is included at no added cost.

Why AI needs its own testing

The AI attack surface is different

AI features change the attack surface. A model that reads untrusted content, calls tools, or acts on a user's behalf can be steered into leaking data, taking unauthorized actions, or bypassing its own guardrails. These failures rarely show up in a traditional scan.

We test the whole system: the model and its prompts and guardrails, the RAG pipeline and vector store, the tools and agents it can invoke, and the APIs around it. Testing is aligned to OWASP guidance for LLM and generative AI applications and the MITRE ATLAS threat matrix, and combined with the application and API testing these systems still inherit.

Grounded in AI security guidance

The AI risk areas we test

We test against the risk areas defined by OWASP guidance for LLM and generative AI applications and the MITRE ATLAS threat matrix. As those standards evolve, our coverage evolves with them.

Prompt injection and jailbreaks

Direct and indirect attempts through user input, RAG content, tools, and web data to override instructions or safety controls.

Sensitive information disclosure

Leakage of PII, secrets, and proprietary data through model responses and error paths.

Insecure output handling

Unsanitized model output that drives XSS, SSRF, or code and command execution downstream.

Excessive agency and tool abuse

Over-permissioned tools, functions, and autonomy that let the model take unintended actions.

System prompt and instruction leakage

Disclosure of hidden prompts and the logic or secrets they contain.

RAG and embedding weaknesses

Poisoning, cross-tenant leakage, and inversion in vector stores and retrieval pipelines.

Model and data supply chain

Risk in third-party models, datasets, plugins, and training or fine-tuning data.

Resource abuse and denial

Unbounded consumption, denial of wallet, and model extraction through abusive queries.

Adversary-informed

Mapped to MITRE ATLAS

MITRE ATLAS maps real adversary behavior against AI systems. We exercise the tactics your model is genuinely exposed to and report findings against the ATLAS matrix.

  1. TACTIC 01

    Reconnaissance

    Profile the model, its version, guardrails, and exposed capabilities.

  2. TACTIC 02

    ML Model Access

    Abuse inference APIs and application entry points to reach the model.

  3. TACTIC 03

    Execution

    Use prompt injection and jailbreaks to make the model act against policy.

  4. TACTIC 04

    Defense Evasion

    Bypass guardrails, safety filters, and content classifiers.

  5. TACTIC 05

    Discovery

    Extract the system prompt, available tools, and model behavior.

  6. TACTIC 06

    Collection & Exfiltration

    Pull sensitive data, training data, or model intellectual property.

  7. TACTIC 07

    ML Attack Staging

    Craft adversarial inputs, poisoning sets, and model-extraction queries.

  8. TACTIC 08

    Impact

    Abuse of agency, denial of service and wallet, and model-integrity erosion.
