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.
Govern with precision
Set per-category policy for every enrolled browser from the dashboard. Warn, block, require justification, or hard-block — your policy, your rules.
- ✓ Per-Category Policy
- ✓ Per-Endpoint Rules
- ✓ Approvals
Zero-leak guarantee
In-browser DLP powered by a fine-tuned Medusa Model. Detects secrets, PII, prompt injection, and 7 more categories. All inference runs locally — text never leaves the browser.
Org-Wide Visibility
Centralized dashboard for every enrolled browser. Findings, warned and blocked submissions, pending approvals, policy enforcement — one pane of glass.
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 inferenceThe DLP model runs locally in the browser. No prompt is shipped to a server for inspection.
- ✓No proxy, no MITMNothing to route, no TLS interception, no network reconfiguration. Install and go.
- ✓You control the dataSelf-host the entire stack on your own infrastructure — or run it fully air-gapped.
