# Locke vs Enterprise AI Plans

Enterprise AI plans bring real contractual upgrades: no training on your data, retention controls, SOC 2 reports, region pinning and admin controls. They meaningfully lower the risk of using a single provider. What they don't change: your prompt still leaves the device, the provider can decrypt it, and provider staff can see it under their own access rules.

## When Enterprise plans of major AI providers fits

- Your organisation has standardised on one or two AI providers and signed enterprise contracts.
- You need provider-level features (custom models, enterprise SSO, admin audit logs) that only the provider can offer.
- You are comfortable that provider contractual controls and independent audits are sufficient for the data you send.

## When Locke fits

- Even with enterprise contracts, some categories of data should not leave your machine: privileged material, PHI, customer PII, regulated financial data.
- Your users mix sanctioned enterprise AI with unsanctioned tools and you want one consistent control.
- You want defence-in-depth: enterprise contract on one side, on-device control on the other.

## Side-by-side

| Dimension | Locke | Enterprise AI plans |
| --- | --- | --- |
| Where data goes | Sensitive fields never leave the device. | All prompt content leaves the device, governed by contract. |
| Trust boundary | Your machine. | The provider's infrastructure plus your contract. |
| Coverage of unsanctioned AI | Same controls regardless of which AI is open. | None. Applies only to the provider you contracted with. |
| Visibility for the provider | Provider sees masked data only. | Provider sees raw prompt content. |
| Best for | Categorically sensitive data and unsanctioned tool use. | Standardising on a vetted provider for general workloads. |

## Bottom line

Enterprise AI plans reduce risk on the provider's side. Locke reduces it on yours. Most regulated teams end up wanting both: the contract for general use, the on-device layer for data that should never leave the machine.
