# Locke vs Enterprise Privacy Platforms

Enterprise privacy platforms (governance, consent and data-mapping suites) help you inventory personal data, manage subject-rights requests and prove compliance. They're essential at scale. They don't watch a free-form prompt as someone types it into a third-party AI tool.

## When Enterprise privacy / governance platforms fits

- You need to inventory personal data across hundreds of systems and meet GDPR, CCPA, and similar regulations.
- You need to manage data-subject access, deletion, and portability requests at scale.
- Your privacy program needs Records of Processing Activities, vendor risk, and consent receipts.

## When Locke fits

- Your governance platform tells you 'employees are using AI tools' but not what they are sending.
- You need a control that operates at the moment of prompt composition, not at the inventory layer.
- You want to keep the privacy layer itself out of the chain of custody (zero-knowledge).

## Side-by-side

| Dimension | Locke | Enterprise privacy platforms |
| --- | --- | --- |
| Layer of the stack | Runtime control on outbound prompts. | Program management, inventory, and rights handling. |
| Touches user data? | Never. Runs locally, no telemetry. | Often, to power inventory and rights workflows. |
| Primary user | End users at the moment they're using AI. | Privacy/legal team running the compliance program. |
| Rollout effort | Per-user install of the Locke Early Access desktop app. | Cross-functional program with system integrations. |
| Best for | Stopping prompt leakage in real time. | Building and proving an enterprise privacy program. |

## Bottom line

These aren't competitors. A privacy platform tells you what data you have and how it's used. Locke stops one kind of leak the platform wasn't built to catch.
