Enigmata Sentinel by Enigmata, Inc.

Keep your AI provider's web app with Enigmata Sentinel.

Enigmata Sentinel helps protect selected sensitive content in supported AI conversations while you continue using your provider's own website. Sign in to Sentinel, use your entitled workspace, and follow the Sentinel status badge as you work.

For supported workflows, Sentinel applies your workspace's protection policy before recognized sends reach the provider. Content selected for protection is substituted in the material sent to the provider. Sentinel presents values you are authorized to see in your local conversation view, so you can work with readable content.

With Sentinel you can:
- Keep using the provider's own web app and account.
- Apply workspace protection policy to supported text and attachment workflows.
- See authorized values in the conversation view, including inside the provider's own content panels (a Claude artifact document, a Microsoft 365 Copilot compose card), which the provider shows in frames on its content hosts.
- Check the status badge for protection state and actions that need attention.

When authentication or protection is unavailable, Sentinel holds recognized sends on supported surfaces and indicates that attention is needed. Coverage depends on the browser, provider, and workflow. Check the support site for the supported combinations and limitations before use.

How your content is processed

To perform protection, the extension sends the full text being protected and original files submitted through supported attachment workflows to Enigmata's Sentinel service over HTTPS. The service processes this content and returns protected content and authorized display data. Read the privacy policy for data handling and retention details.

Your choice, first

Nothing is processed until you enable protection on Sentinel's settings page, which explains what is sent to Enigmata, when, and for what. Signing in does not enable it by itself. The same page lets you sign out, or stop protection so nothing is processed until you enable it again.

Account requirements

The extension is free to install. Use requires a Sentinel account and a workspace with access to the Sentinel service. Workspace access may be provided by your organization or through an eligible Sentinel plan. A provider account is also required and is separate from your Sentinel sign-in. Any provider subscription is separate.
