Securing the Algorithms That Drive Business Decisions

AI and machine-learning systems support use cases including LLM chatbots, fraud detection, clinical workflows and automated decision-making. These systems introduce attack paths across models, prompts, training data, APIs, tools and third-party components.

NSI Global tests AI and ML systems for direct and indirect prompt injection, sensitive-information disclosure, excessive agency, insecure output handling, model extraction, inference attacks, data poisoning and supply-chain compromise. Findings document the affected component, reproduction evidence, likely impact and prioritised remediation.

Where applicable, testing is mapped to the OWASP GenAI LLM Top 10 2026 and MITRE ATLAS, with governance findings referenced to the NIST AI Risk Management Framework and its Generative AI Profile.

What We Assess

Model Exploitability

Test whether adversarial inputs can bypass controls, alter intended behaviour, expose protected information or trigger unauthorised actions.

LLM Security & Prompt Injection Testing

Test direct and indirect prompt injection, jailbreaks, retrieval-augmented generation inputs, system-prompt exposure and tool or plugin misuse.

Model Extraction & Inference Risks

Assess whether interfaces disclose model behaviour, membership, training data or proprietary outputs to a degree that could support reconstruction or imitation.

Testing for Data Poisoning & Supply Chain Threats

Review datasets, preprocessing and training pipelines, model repositories, libraries and third-party integrations for poisoning, tampering, provenance and dependency risks.

Risks Covered

  • Disclosure of sensitive prompts, data or system instructions
  • Manipulation of model behaviour or decision outputs
  • Unauthorised actions through connected tools or agents
  • Poisoning or tampering affecting training and inference
  • Weaknesses in model, dataset and dependency provenance
