Is TNB Teknoloji Elektronik İmza safe?

Clean risk

TNB Teknoloji Elektronik İmza bridges KEP signing pages to a local native application for digital signature operations.

The extension runs only on TNB Teknoloji's KEP (registered electronic mail) domains. When those pages trigger a signing request via a custom DOM event, the extension relays the request to a locally installed native host named 'tnbtimzahost' and returns the response to the page. No user data is transmitted to remote servers; all messaging stays between the browser page and the local native application.
