Is Rave Companion safe?

Clean risk

Rave Companion sends Medidata Rave page, login, study, and form data to a local Companion WebSocket.

On Medidata and Medidata Rave pages, the extension gathers login metadata, study identifiers, subject and form details, field counts, and form row data. It forwards that JSON to a local process at ws://localhost:8587/ for the Companion product suite.

Where it sends data

Destinations our analysis observed Rave Companion contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
