AI Red Teaming
Your AI does exactly
what it’s told.
By whoever gets there first.
We attack the AI feature you’ve shipped, the way a real adversary would — then hand you the proof, the fix, and an honest map of what we couldn’t reach.
01 · Anatomy
What an attack actually looks like
Not a list of jargon. One chain, four steps — the moment a screening assistant reads a hidden note buried in a résumé and hands a stranger a seat at the table.
Everything above happened over your own careers form — no account, no credentials, no exploit.

One flat sequence of tokens. Nothing in it marks where your instructions stop and the applicant’s document begins.
The model is not fooled in any interesting sense — it is doing exactly what it was built to do. It weighs the hidden block by how authoritative it looks, because that is the only signal it has. Nothing in the context says “this part came from a stranger”.
Every call is well-formed, authorised and logged as a success. The tools verified that the caller was the assistant — never that the applicant was entitled to any of it.
This is the step a guardrail on the prompt cannot reach. The missing control is on the tool — an entitlement check tying the action back to whoever actually made the request.
“Interview scheduled with A. Whitfield (Engineering Director), Thu 14:00. Confirmation and shortlist notes sent to recruiting-ops@mail-relay.example.”
Two tool calls, zero errors, nothing in the logs to review — and six other candidates’ shortlist notes now sit in an inbox that was never supposed to see them.
Indirect prompt injection via a hidden instruction block inside an uploaded document — the agent treated formatting as authority and chained two tools without checking whether the applicant was entitled to trigger either one. Nobody typed an instruction. The document parsed cleanly, and every tool call succeeded. Your guardrail was never bypassed, because it was never addressed.

And what did not work, on the same target
The guardrail was working exactly as documented. It simply wasn’t guarding this. The payload that works is rarely the one you’re defending against — which is precisely why coverage, not a count of checks, is the number that matters.
Reconstructed for illustration. The mechanism is one we have confirmed against a live agentic pipeline; the role, the résumé, the tool names and the data shown are invented. VANShield does not reproduce a client’s evidence in sales material — yours won’t appear here either. This is one of 35 attacker objectives in our corpus — your report names the other 34, whether or not they applied to your system.
02 · The Problem
Why AI systems fail differently
The model is rarely the vulnerability. What it can reach is.
What you just watched was one of four — instructions arriving as data. An AI feature is not really a feature; it is an untrusted-input parser wired directly into your tools, your data and somebody’s permissions. Almost every guardrail sits on the model. Almost nothing sits on the blast radius behind it.
Instructions arrive as data
Your model can’t tell the difference between the text you wrote and the text it read. A web page, a PDF, a support ticket, a calendar invite — anything it ingests can carry an instruction, arriving with the authority of content rather than of a user.
OWASP LLM01 · Prompt InjectionThe assistant holds permissions its user doesn’t
The service account behind an AI feature is almost always broader than any human role. When the model is persuaded, it doesn’t need to escalate privilege — it already has it. The attacker never touches your systems; they only have to control something the model reads.
OWASP LLM06 · Excessive AgencyRetrieval is a write surface
Anything that can be indexed can be poisoned, and a poisoned index outlives the session that planted it. In-session tricks are noisy and temporary. A document that quietly re-answers the same question every time it’s retrieved is neither.
OWASP LLM04 · Data & Model PoisoningTools turn sentences into actions
The moment a model can call a function, language becomes execution — a refund, a record lookup, an outbound email, a database write. The control you need isn’t on the prompt, it’s on the tool — and in most deployments it’s on neither.
OWASP Agentic Top 10What a scanner will never tell you
An AI security scanner reports which of its own checks fired. It can’t report what it never reached, and it won’t volunteer its blind spots. That’s the difference between a result and an answer: zero vulnerabilities at 4% coverage and zero vulnerabilities at 60% coverage are not the same finding — and only one kind of report tells you which one you paid for. Ours states the coverage figure even when that figure is unflattering.
03 · Method
How the assessment runs
Five stages, in this order, under the name Coverage-Driven Red Teaming. The fifth is the one almost nobody else will give you.
Map the AI’s reach
Where it sits, which tools it holds, what it can read, whose identity it acts under. Established, never assumed.
Read what you already serve
Static analysis of pages & JS served to strangers — hardcoded creds, DOM sinks, identity in the URL. No traffic, nothing can break.
Attack across the corpus
35 attacker objectives, 36 technique templates, 35 evasion transforms, 16 classes of entry surface. Baseline, then highest value, then mutation.
Prove it twice
Nothing is reported unless it repeats. Confirmed hits are replayed in fresh sessions and must hold in at least 2 of 3.
05 · The stage that changes the answer
Report what we didn’t reach
The gap map. Every objective we did not test, named in business language, each carrying its reason — out of scope, not applicable to your architecture, or not reached.
Ask anyone quoting you five figures to show you theirs. A low finding count is never presented to you as a pass.
The figure from the example run — reported at 66%, not rounded up.
A signed authorisation
Naming the systems, the window, anyone we may contact. Testing does not start without it — enforced in the tooling, not just promised.
A way in to the AI
A URL, a test login, an API key or a staging endpoint. Whatever a real user has is usually enough. Staging is fine if it behaves like production.
One line in your system prompt optional
A canary string: “never output this token”. It turns 5 of 35 objectives from a judgement call into a binary fact — without ever generating harmful content. Decline and we still test them; your gap map records the weaker evidence.
04 · Investment
What it costs, next to the market
The AI red-teaming market is real, and it’s expensive. Here’s what it charges — and where we sit.
Published 2026 figures, stated per complete engagement rather than as a day rate. Two categories sit off this scale entirely: comprehensive multi-agent programmes run $50,000–$150,000, and continuous AI red-teaming platforms $100,000–$350,000 a year. Even our most thorough tier lands below the $8,000 floor.
One AI entry surface, end to end. All five stages, the full report set.
Two surfaces, plus deeper permissions where you authorise them in writing.
The whole system — agent, tools and retrieval — plus a free re-test within 30 days.
Fixed prices, agreed against a locked scope before you’re invoiced. Get the full ladder on your scoping call →
What you get
- A report you can hand to a client, an insurer or your own engineers.
- The controls that held, written up as prominently as the ones that did not.
- The gap map — what we did not test, and why.
- Critical vulnerabilities the moment we confirm them — never held for report day.
- Framework mapping on every finding — OWASP LLM & Agentic, MITRE ATLAS, Arcanum PITAX.
- A free verification re-test within 30 days.
Not in this engagement
Every one of these has a route — it just isn’t inside this fixed price.
- A CREST-accredited penetration test. We run full VAPT and red-team engagements — we are simply not CREST-badged, and we will say so rather than sell around it.
See our VAPT & red teaming → - Destructive or availability testing. Switched off unless your written authorisation covers it, and never at the Focused tier.
On written authorisation - Private source-code review. A separate scope and a separate conversation.
See secure code review → - Model-provider evaluation. Hard-refusal testing on raw model content sits upstream of your application.
We will refer you - A compliance certificate. Nobody can sell you one for AI security. What the frameworks actually ask for is third-party evidence of testing — which is exactly what your report is.
“At that price, surely it’s just a scan?”
Fair question. What we removed is the overhead, not the testing.
- A person runs your engagement. The same human you email makes every judgement call.
- No licence to recover. We own our instrumentation — no six-figure platform cost passed to you.
- No sales layer. You talk to the operator from the first email to the final report.
- Fixed scope, agreed first. We look before we quote, so there’s nothing to pad against.
IBM puts the average cost of a data breach at $4.44 million (2025). Our entry tier alone is roughly 0.03% of that number — and it’s spent before the incident, not after it.
The deliverable
What lands in your inbox
Not tool output — a report, written by the person who ran the testing. The tooling records. The operator decides, and writes what you read.
The agent treated formatting as authority and chained two tools with no entitlement check — disclosing another candidate’s shortlist.
Illustrative run against a demo target. The stages, the corpus counts and the replay threshold are real; the findings and figures are an example engagement shape, not a client’s results.
