LLM Penetration Test
Structured attack testing against your deployed LLM application — scoped, documented, and reproducible, in a format your customers and auditors accept.
Sound familiar?
- Standard web pentests stop at the API and never touch the model layer.
- Jailbreaks and system prompt extraction have never been tried on your system.
- Tool-calling paths allow actions the interface never intended to expose.
- There is no report to show when a customer asks whether the AI was tested.
What we do
System prompt & guardrail testing
Extraction, override and bypass attempts against your instructions and filters.
Data exposure
Leakage of other users' data, internal documents and configuration.
Tool & function abuse
Making the application take actions outside its intended authorisation.
Reporting
Severity-ranked findings, reproduction steps, and a remediation plan.
Questions we get
How long does a test take?
Typically one to two weeks depending on scope, plus a retest after remediation.
Can we share the report externally?
Yes. We write it to be shareable with customers and auditors.

We'll tell you what we'd check first — and what we wouldn't bother with.
