Safety and trust

Built for teams that cannot take risks

Large and regulated teams ask one question first: where does the data go? With SteerPlane it stays in your environment. And every check runs before the step does, not after.

Principles

Six things we never compromise on

Rules decide, not a model

Every check is deterministic. The same step always gets the same answer.

Checks before the step runs

A blocked call never reaches your tools or database. It is stopped, not reported later.

Fails closed

If the control plane goes down, the SDK keeps enforcing limits locally.

Your data stays yours

Self-hosted keeps everything in your environment. Cloud-hosted runs on a dedicated instance. We never sell or share your data.

Keys stay on the server

Your provider key never sits in the agent process.

Open code you can audit

The core engine is on GitHub. Your security team can read every line.

How a step is checked

Nothing runs until it passes

  1. 1

    Agent proposes a step

    A model call or a tool call, with its arguments.

  2. 2

    SteerPlane checks it

    Against your cost ceiling, step limit, loop rules and action policies.

  3. 3

    Allow, stop or block

    Allowed steps run. Anything else is stopped before it reaches your systems.

  4. 4

    Every decision is logged

    In your own database, for debugging and audit.

Where it runs

You choose where your data lives

Self-hosted

Run the API, gateway and dashboard on your own servers or in your VPC. Prompts, tool calls and run data never leave your network.

Cloud-hosted

We run a dedicated instance for your team, in the region you choose. Nothing is shared with other customers.

Enterprise

On-premise or in your own cloud account, with help through your security review and a named contact.
