When Cloud-based DLP platforms fits
- You already operate a corporate proxy or CASB and need to extend coverage to a sanctioned set of SaaS apps.
- Your compliance program requires central policy enforcement and an auditable inspection record on every transmission.
- Your AI usage is funnelled through a single approved provider that exposes admin APIs.
When Locke fits
- Users routinely paste sensitive content into AI chat boxes that are not on your sanctioned list.
- You cannot route every browser session through a proxy without breaking workflows or trust.
- You want detection to happen before the data leaves the device, not after.
Side-by-side
| Dimension | Locke | Cloud DLP |
|---|---|---|
| Where inspection runs | On the device, before any network call. | On a server-side gateway, after data leaves the endpoint. |
| Coverage of unsanctioned AI tools | Works on supported browser-based AI chats by default. | Limited to apps the gateway proxies or has API hooks for. |
| Trust model | Zero-knowledge: vendor never sees prompt content. | Vendor inspects prompt content to enforce policy. |
| Deployment | Locke Early Access desktop app: minutes per user. | Network/identity integration: weeks to months. |
| Best for | AI-specific prompt leakage in regulated workflows. | Broad enterprise DLP across email, files, and managed SaaS. |
Bottom line
Cloud DLP is the right call for broad enterprise data flows. Locke is the right call for AI prompts, the newest exfiltration channel and one that usually skips your gateway.
