Is Netwrix EPP Browser Connector safe?

Clean risk

Netwrix EPP Browser Connector captures page text and document content, relaying it to the local Netwrix Endpoint Protector native app.

The extension injects a content script on all pages. When instructed by the native Netwrix Endpoint Protector application via a native messaging port, it collects the visible text of the current page, fetches file contents from Google Docs, OneDrive, and SharePoint documents as byte arrays, and captures PDF bytes by URL. All collected content is relayed to the local native host 'com.cososys.epp_browser_connector' over a long-lived native messaging port, and page content is also captured on print events.
