AI security
Secure the AI you're shipping, not just the code around it.
Chatbots, copilots, RAG search and autonomous agents bring a new attack surface where data becomes instructions. We break them the way attackers will, then help you build guardrails that hold.
Why it matters
One poisoned document. Full agent takeover.
Agents read untrusted content and act with real permissions. Without the right design, an attacker never needs to touch your servers: they just need your AI to read something they wrote.

What we test for
The AI attack surface
Mapped to the OWASP Top 10 for LLM Applications, OWASP agentic AI guidance and MITRE ATLAS.
Prompt injection
Direct and indirect: instructions hidden in emails, documents, web pages or tool output that hijack your model.
Excessive agency
Agents with more tools and permissions than they need, turning one injection into real-world actions.
Sensitive data leakage
System prompts, PII, secrets or another customer's data surfacing in responses.
RAG & vector store risks
Poisoned knowledge sources and retrieval that ignores who is allowed to see what.
MCP & tool supply chain
Untrusted MCP servers, plugins and tool descriptions that smuggle instructions or over-reach.
Insecure output handling
Model output passed unchecked into browsers, shells, SQL or other systems.
Credential & identity misuse
Agents acting with shared or over-privileged credentials, with no per-user authorisation.
Guardrail bypass
Jailbreaks, encoding tricks and multi-turn attacks that slip past your safety filters.
Services
Three ways we secure your AI
AI & LLM Security Testing
LLM and AI chatbot penetration testing for RAG pipelines, AI agents and MCP servers: prompt injection, data leakage, tool abuse.
AI Threat Modeling
Design-stage threat modeling for LLM apps and agentic systems: data, tools, autonomy and trust.
AI Application Security
Secure code review and guardrail engineering for the code that wires LLMs into your product.

FAQ
AI security questions
We use a major model provider. Isn't security their job?
Providers secure the model. You're responsible for everything around it: what data it can see, which tools it can call, what it's allowed to do and how its output is used. That's where real-world AI incidents happen.
Can you test agents built on LangChain, LlamaIndex, CrewAI or custom frameworks?
Yes. Our testing is framework-agnostic. We focus on the behaviour of your system, its tools and its permissions, whatever it's built with.
Do you test MCP servers?
Yes, both MCP servers you build and the third-party ones your agents connect to, covering tool poisoning, over-broad permissions, authentication and data exposure.
Should we threat model or test first?
If you're still designing, start with an AI threat model: it's cheaper to fix architecture early. If you're already live, start with testing, then use the results to drive the threat model.
Launching an AI feature or agent?
Talk to us before it goes live. A short call is enough to identify your biggest AI risks and the fastest way to address them.
