Aligning humansand agents.

Leyn turns your policies into controls for AI agents, so your people stay in charge as agents scale.

One rulebook in. One record out.

Align

Rulebook

Your policies, direction and governance documents, turned into controls. Each control points to the passage and version it comes from.

Guard

Three layers.

Every action is checked in up to three layers: a fast deterministic filter, then models that flag and decide in real time, then a review of the whole task.

How deep the checks go depends on the agent’s tier.

Escalate

Escalate or stop.

Most actions pass. When a layer flags one, Leyn routes it, holds it or stops it.

The case reaches a named person from your delegation matrix, with alternatives and their impact on cost, risk and value.

Assure

Record

One signed record per decision, written the moment the rule is applied: rule, passage, version, outcome, who decided.

Risk management for agentic AI: runtime controls built from your own policies and processes.

Filter at speed and see what matters.

Keep cost, risk and direction in check.

See

See every agent action.

Activity, timelines and records.

Align

Turn policies into checks.

Each check traced to your own documents.

Guard

Escalate or stop.

Every action checked against your controls before it takes effect.

Assure

Evidence on hand.

A record of every decision, ready for audit.

Every task, accounted for.

Account

Every action has a name, a purpose and a cost.

Mandate

A defined task, and the resources granted to complete it.

Rules

Checked against each action taken to complete the task.

Review

What was delivered, and at what cost.

Each control is set per task and per run, from documents you already hold.

How it works

From your documents to governed agents.

Build turns your documents into observable rules. Run applies them to every agent action as it happens.

Build

Turn your documents into observable rules.

  1. 01

    Ingest

    Leyn reads your direction, constraints and governance documents.

  2. 02

    Enrich

    Leyn proposes: you approve.

  3. 03

    Represent

    Direction, constraints and governance, mapped in one knowledge graph.

  4. 04

    Compile

    Each obligation becomes a rule stated as what an agent can be seen to do.

Observable rulesOutput of Build, input to Evaluate.

Run

Govern agent actions at runtime.

  1. 05

    Scope

    Selection: based on scope and risk, the tier and rules that apply to the agent.

  2. 06

    Observe

    Telemetry from every tool call and MCP call.

  3. L1 · L2 · L3

    07

    Evaluate

    Each action is checked against the rules: deterministic checks, probabilistic models and LLM as judge. Leyn judges the whole task across steps and systems, and confirms what changed in the target system’s own logs.

    Three layers, extent of monitoring depends on tier.

    • L1A deterministic filter answers what is certain, on every call.
    • L2Inline guard models detect, decision models filter out what matters.
    • L3Judges the whole task, across steps and agents, and prepares the alternatives a person sees.

    The first two layers keep the third, and routing, rare.

  4. 08

    Act

    Most actions pass. When a layer flags one, Leyn routes it, holds it or stops it.

Three roles, three views.

Built for owners, operators and experts.

The people who own the policies or agents decide whether an action is in or out of bounds.

Owner

Accountable for an agent or a policy.

Operator

Runs the agent.

Expert

Knows the field the rule covers.

Runs where your agents run.

The part of Leyn that sees your agents’ traffic runs in your cloud or on your premises. Agent traffic and customer data stay inside your Data Boundary.

Agents that follow your direction.

Leyn is a Stockholm-based company building controls for agentic AI, so people and agents work toward the same goals.

Start with one agent.

We show you what it does and how Leyn checks it against your rules.
