The Invisible Shield for AI Data Loss

A browser extension that runs a DLP model right in the browser, warning your team before they paste secrets, PII, or source code into AI tools. Roll it out across your org and set the policy from one dashboard.

No proxy. No MITM. Prompts are inspected on-device — never sent to a server to be scanned.

Scan everything

The extension scans everything your team types or pastes into ChatGPT, Claude, Gemini, Copilot, Perplexity, Grok, and more — in the browser, before it ever leaves the page.

Org-Wide Visibility

Centralized dashboard for every enrolled browser. Findings, warned and blocked submissions, pending approvals, policy enforcement — one pane of glass.

Private by architecture

Your data never leaves the device

Most AI-security tools are network proxies that route every prompt your team writes through a vendor cloud to inspect it. Medusa does not. The detection model runs entirely inside the browser— so the content being checked is never sent anywhere to be scanned.

  • On-device inference
    The DLP model runs locally in the browser. No prompt is shipped to a server for inspection.
  • No proxy, no MITM
    Nothing to route, no TLS interception, no network reconfiguration. Install and go.
  • You control the data
    Self-host the entire stack on your own infrastructure — or run it fully air-gapped.
