AI & LLM Security
Adversarial testing of LLM applications, agents, RAG pipelines and machine-learning models, mapped to OWASP guidance, MITRE ATLAS and the NIST AI RMF, with support for EU AI Act readiness.
We test direct and indirect prompt injection, system-prompt and data disclosure, poisoned retrieval sources, excessive agent permissions, unsafe tool use, resource exhaustion and other system-specific abuse cases. Testing is adapted to the application architecture and authorised data flows.
The assessment is structured around the OWASP Top 10 for LLM Applications, MITRE ATLAS and the NIST AI Risk Management Framework. Results distinguish application defects, model limitations, architectural risks and governance gaps.
For organisations preparing for the EU AI Act, we support system inventory, preliminary risk classification, technical documentation and repeatable security testing within the AI development lifecycle.
- OWASP LLM Top 10
- every risk tested, LLM01–LLM10
- MITRE ATLAS
- adversary techniques mapped
How it works
- 01
Scoping & AI inventory
Map models, LLM apps, agents, RAG sources and data flows; classify by EU AI Act risk tier.
- 02
Threat modelling
Derive AI-specific threats using the OWASP LLM Top 10 and MITRE ATLAS.
- 03
Adversarial testing
Hands-on red teaming – prompt injection, jailbreaks, RAG poisoning, agent and model attacks.
- 04
Analysis & reporting
Risk-rated findings with proof of impact, mapped to OWASP/ATLAS/NIST and remediation.
- 05
Governance & retest
AI RMF-aligned controls, EU AI Act evidence and re-testing (optional).
