Highline AI Book a demo
Patent pending

Private, governed, secure AI agents

A complete platform a company runs inside its own environment to build, run and control AI agents end to end. Agents work inside real limits, a named person approves what goes beyond them, and every action is kept in a record an auditor can check.

Platform

What an AI agent is, and why most companies cannot deploy one

The agent

An agent takes actions.

It does not only answer questions. It credits a guest, approves a loan, changes a record or sends a payment. That is where the value is, and where the risk is.

The problem

Most companies cannot let it act.

In a company that is regulated or holds sensitive data, the data cannot leave. Nothing counts what agents have already done, so many small allowed actions can add up to one breach.

Highline AI

Highline AI lets it act within limits.

Highline AI runs the agent inside your environment. It counts what AI has done to each customer, account or record across every agent and system. A named person approves anything above the limit.

Console

The Highline Console

Each team sees what its agents did, what waits for a named person and what was refused. Below, payments at a building society.

Why checking one action at a time is not enough

A hotel sets a limit on goodwill per guest stay. Three agents in three systems each credit the same guest. Move any slider and watch the total.

£150
Set by the hotel, in pounds
£60
Credit in the property system

Voucher through the booking channel
A limit on each action£180
A limit on the total, with Highline AI£120
Guest services agent£60 fits. Running total £60 of £150.
Allowed
Front desk agent£60 fits. Running total £120 of £150.

Reviews agent£60 would take the total to £180. A named person decides.
Needs approval

Needs approval. The action waits for a named person at the hotel. No answer means no. The limit is in the business's own units, pounds, records or permissions, never a count of actions, because an agent can split one action into many.

Foundations

Five things in every deployment

An agent that only answers questions needs none of them. An agent that opens accounts, moves money or changes records needs every one.

Private.

Runs in your cloud, your data centre or fully offline. Any model. No data leaves.

Protects againstYour data passing through a vendor's cloud.

Built into the work.

The agent acts inside your booking, banking or document systems, not a chat window.

Protects againstAgents acting where nobody enforces your rules.

Real limits, enforced automatically.

A cap on the total across every agent and system. Patent pending.

Protects againstSmall allowed actions adding up to a breach.

A person is always in the loop.

A named person approves anything above the limit. No answer means no.

Protects againstAn agent acting beyond its authority.

A full, permanent record.

Every action, who approved it and why, sealed and timestamped.

Protects againstLogs edited after the fact. Verifiable without Highline AI.

Hover a card to see what it protects against.

In a company that is regulated or holds sensitive data, agents cannot be deployed without this end to end control, governance and traceability.

Architecture

How one action runs

The agent proposes an action. A separate part decides whether it is allowed. A third part carries it out with credentials the agent never sees. If any check fails, the action does not happen and the attempt is recorded.

Propose

Highline Vector

Runs the agent in a sealed sandbox with no credentials. It can only ask.

Check

Highline Gate

Compares the live server to its signed, approved setup. If anything changed, the action stops.

Decide

Highline Governance

Reads the running total and applies the rules your compliance team wrote.

Approve

Highline Sentinel

Asks the named person when the limit requires it. No answer means no.

Act

Highline Vault and Highline Bridge

The only parts that hold credentials. They act and update the total.

Record

Highline Ledger

Writes every step to a chained, timestamped record you can verify without Highline AI.

Security

How Highline AI guards your systems

Four layers. Each card names the risk it removes.

Separation of duties.

The agent proposes, a separate part decides, a third part acts. They exchange signed tokens and nothing else.

Protects againstA hijacked or confused agent acting on your systems. All it can do is ask.

The machine is checked before every action.

Highline AI keeps a signed copy of each server's approved setup and compares the live server to it.

Protects againstTampered or drifted servers. If anything changed, the action stops.

Every agent is contained.

Every AI change to a customer, account or record is counted across all agents and systems. Patent pending.

Protects againstSmall allowed actions adding up to a breach.

Tamper evident record.

Every action, decision and approval is sealed with a timestamp from an independent authority.

Protects againstLogs edited after the fact. An auditor can verify the record without Highline AI.
Comparison

How Highline AI differs from Google, Microsoft, Mistral, ElevenLabs and the agent startups

They build and run good agents. The difference is where the data, the governance and the record live.

How the large platforms work
How Highline AI works
Runs in their cloud.Your data and the agent's actions pass through the vendor, which fails compliance in most cases involving sensitive data.
Runs in your environment.Your cloud, your data centre or fully offline. No data leaves.
Model on your premises, governance in theirs.Some can put the model on your premises. The governance stays in their cloud.
Everything on your premises, any model.Governance, approvals and records never leave your environment.
Governance sold as parts.A registry, access rules, policies and audit logs for you to assemble.
Governance built in.Set by configuration. Limits, approvals and records work from day one.
Agents cannot be contained.Each request is allowed or denied on its own. Nothing adds up the total, so a limit is passed by splitting the work.
Agents cannot escape their limits (patent pending).Highline AI counts what AI has done to each customer, account or record across every agent and system.
The vendor keeps the record.The system that acts also holds the credentials and keeps the log. It checks its own homework.
You keep the record.Sealed, timestamped and verifiable without Highline AI. Highline AI never sees it.
Sectors

Who buys Highline AI

Any company that has to answer for what its AI does, to a regulator, a board, shareholders or customers. Regulated or not. Sold direct and through partners.

Banking

Account opening, KYC checks and loan decisions.

AI must stay inside the bank's thresholds, with proof. Weak controls cost UK banks tens of millions in fines.

Example limit£5,000 of AI adjustments per account per day, across refunds, collections and support agents.
Hospitality

Guest service, front desk and reviews.

Guest facing AI hands out credits, points and vouchers across several systems, so the cap must be per guest.

Example limit£150 of goodwill per guest stay, however many agents handle the guest.
Pharma and clinical

Clinical trial documentation.

AI that drafts or changes trial documents needs a named reviewer on every change and a record the regulator can inspect.

Example ruleEvery AI change to a trial document waits for a named reviewer.
Health technology

Patient data processing.

AI that processes patient data needs a named reviewer and a record. Patient data stays inside.

Example ruleNo patient record leaves your environment. Every access is recorded.
Property technology

KYC checks and property matching.

AI that checks applicants and matches buyers to sellers works on personal data, financial data and client money.

Example limit20 applicant records changed by AI per day before a person reviews.
Media and marketing

Proposals, budgets and campaign KPIs.

AI that drafts budgets and tracks campaign spend works on client money and client data.

Example limitAny AI change to a campaign budget above £1,000 needs a named approver.

Hover a sector to see an example limit.
