01 · what you already run

Your assistants read what strangers write.

Then they act. An email arrives, the assistant reads it, and one step later something is sent, written, paid or deleted. Nobody has to break in.

a small bank: 6 assistants · 14 tools they can call · 5 sources nobody checks
The estate. Every place the institution runs a language model that reads text it did not write and can do something afterwards. It is inventoried at intake and rediscovered continuously, because the third item on any list of agent incidents is the agent nobody knew about.
02 · five numbers

Why this product is an absolute must.

None of this is a projection about robots. It is money that already moved.

Read the fourth and fifth together. Shadow AI at 43% and missing access controls at 92% describe the same estate: tools arrive through employees rather than procurement, and nothing scopes what they can reach once they are in.
03 · the ten attacks

Ten ways an agent gets turned. Pick one and watch it happen.

Ranked by how often it lands and how much it costs when it does. Click any attack on the left to see a real example play out, step by step, and where it gets stopped.

Vocabulary. The classes follow the OWASP Top 10 for Agentic Applications, published 9 December 2025. Using the published list means the finding an auditor reads and the finding your engineers read carry the same name, and the ranking here is by observed frequency and cost rather than by list order.
04 · how it is built

Seven parts. One of them is a person.

All of it sits inside your own walls. Hover or tap any part to see what it does.

Seven parts: taps, lens, ledger, desk and policy engine inside the client's walls; the range and the learning loop outside. inside your walls · your keys · your data outside · ours · sees no client data every line exports to your SIEM whatever the policy does, it acts back on the agent a planted instruction arrives your agents taps part 1 lens part 2 ledger part 3 desk · a person part 4 policy engine part 5 the range part 6 the learning loop part 7

hover, tap or tab through any of the seven parts

the path an attack takes: agent → tap → lens → desk → policy · the ledger records every step of it
The doctrine sentence. Assume the model can be tricked, then make sure a tricked model cannot do damage: least privilege, allow-listed tools, your own people approving anything consequential, everything sandboxed and audited, all of it running inside your environment.
05 · how it decides

Cheap checks first. The AI is the last resort.

A thousand things happen. Simple rules settle almost all of them for nothing. A small model looks at what is left. A large model is asked about a handful, and even then it only writes an opinion.

ruleslayer 1
Allow-lists, known bad patterns, marker text hidden in documents that should never be quoted back, and hard limits on volume. Costs nothing per event and never surprises anyone.
0of 1,000
classifierlayer 2
A small model that knows the shape of an injection, and notices when the action proposed has drifted away from the task asked for.
0of 1,000
judgelayer 3
A frontier model with our whole library of past attacks behind it. Called only when the first two disagree. It returns a finding. It never returns an action and it holds no key.

finding · written to the ledger
class: goal hijack
severity: S1
decided by: layer 1
why: marker text quoted in an outbound draft
proposed: hold the send, ask the desk
cost: 41 ms, no model call

Every verdict says which layer decided and why. Your auditor can replay it and get the same answer.

rules → classifier → judge · a model is called only where a function could not be written
Why the order matters. Deterministic checks run on every event at fixed cost and produce a repeatable verdict, which is what a regulator asks for. Probabilistic judgement is expensive and unrepeatable, so it is reserved for the small tail where the cheap layers disagree or a severity threshold is crossed.
06 · your people

Your people decide, in twenty seconds, from a phone.

We do not sit in your escalation chain and we do not know your business. Your officer does. The product's job is to make that decision take twenty seconds instead of a meeting.

The card shows the evidence, not the agent's summary of it. That one choice is most of the defence against an agent that talks a person into approving harm.

approve, edit or reject the card · every outcome is recorded with what the approver saw at the time
The record. Every decision is written with its latency, the roster position that answered, and a hash of the evidence rendered on screen. An approval you cannot reconstruct is not a control, and the reconstruction is what a DORA or EU AI Act reviewer asks to see.
07 · when nobody answers

The AI recommends. The policy acts. The ledger records.

Acting alone is a narrow, signed, reversible exception. It is never a mode you leave switched on.

Replayable containment. The engine's decision procedure is a state table, not a model call, so an auditor can take any ledger line and reproduce the same action. Default timers are set by you at intake: five minutes for the top severity, thirty for the next, next business day below that, a weekly digest at the bottom.

09 · the rehearsal

Watch it before you buy it. Forty-five minutes, nothing installed.

We build a copy of your assistant in our sandbox: your instructions, your tool list with the tools disconnected. Then we attack the copy while you watch.

attacker · 15 scenario types · pick one to fire it
VS
a copy of your assistant
your instructions
your tools, disconnected
your sources, seeded with planted text
no production data · nothing installed
every scenario you fire here is one the regression suite runs on every release · two of the fifteen land
What comes out. Five artefacts: an injection surface map, a tool-permission audit, a data-flow map, a list of the places a human gate is missing, and a hardening plan with effort estimates. Every scenario that lands becomes a rule, a training example and a permanent test.
10 · three products, one codebase

Three ways to deploy it. Watch each one go in.

You can start with the one that touches nothing, and stop there. Each step up is the same software with more of it switched on, in more places.

We attack a copy of your assistant while you watch.

Nothing is installed on your side. Nothing of yours is connected. We rebuild your assistant in our sandbox from two things you already have written down, and then we try fifteen ways to turn it. You get a report and a fix list.

no install · no production data

All of it in our sandbox. Your systems are not touched, and no production data leaves your side.
how long
A forty-five minute demo you watch. Then about a week to run it properly against your real estate and write it up.
what you are left with
Five documents and a fix list. Useful even if you never buy anything else from us.
Technically. A digital twin is built from the target's system prompt and tool manifest, with every tool stubbed and retrieval sources seeded with planted text. The attacker agent runs the scenario library against it. Output is the five-part assessment: injection surface map, tool-permission audit, data-flow map, human-in-the-loop gap list, hardening plan with effort estimates.
one codebase · three shapes · the seven parts never move, only how much is switched on
11 · who holds what

You keep your data. We keep the rules.

The most common reason a bank says no to a security vendor is that the vendor wants a copy of everything. We do not want one, and the product is built so that we could not take one.

your side

Everything that identifies you

  • Your prompts and your documents
  • The ledger, and the keys to read it
  • The credentials the policy engine may revoke
  • Your people, on their own channels
  • The switch that turns any of it on or off
If we disappeared tomorrow, this keeps running and you keep the record.
our side

Nothing that identifies you

  • The library of attack patterns, stripped of whose incident it was
  • The rules and the detection models
  • Signed releases and updates
  • Counts, so we know the product works
No prompts. No documents. No keys. No customer records. Not by policy, by architecture.
Two planes. The control plane distributes templates, rules, the abstracted pattern library and release signatures; the execution plane holds all content and all credentials and lives in the client's boundary. Findings are abstracted before they leave a tenant: the pattern travels, the client's data never does. Residency is a configuration value, and the air-gapped shape removes the upward link entirely.
12 · the market

Nine companies bought in eighteen months. None of them sells to a two-hundred-person insurer.

The buying proves the problem is real. The gap is who nobody is serving.

What is hard to copy. A first-hand library of findings from production deployments, categorised with the fix and the hours it took. The acquirers on the top shelf bought filters, not libraries. Second: having actually run agents in production for clients, with the audit trails to show for it. Most sellers in this category have advised. Few have operated.
