Is MetaDefender Endpoint Download Protection safe?

Clean risk

MetaDefender Endpoint Download Protection sends completed download URLs to an OPSWAT native host.

When a browser download finishes, the background service worker looks up the download item and forwards its metadata to the local native messaging host com.opswat.gears.client.mafbridge. The recorded claim identifies the download URL as included in that payload.
